Field of the Invention

[002] This disclosure is related to the field of network communications. In particular, it relates to systems and methods for aggregating signals in a mesh network.

Description of the Related Art

[003] The“smart” movement is an attempt to utilize interconnected devices as a way to generate data and supply improved and more targeted services. The basic concept is that when “things” can communicate with each other and with users, a wealth of data can be made available, often in real time, which can then be accumulated and analyzed without the need for users to manually gather, store, and organize this information.

[004] One area where this concept is now being implemented is in the“smart city” movement, in which municipalities leverage various types of automated data collection to provide information that can be used to manage municipal assets and resources in an efficient and effective manner. These efforts rely on a variety of data sources, ranging from data collected automatically by devices in various locations throughout the city, to devices carried by citizens or employees. Data may also be collected by or from vehicles, or provided directly by citizens. “Smart city” strategies can help improve the delivery and efficiency of city services, such as law enforcement, trash collection, public safety, traffic management, and even achieve reductions in pollution and crime.

[005] Commonly,“Internet of Things,” or IoT, devices are leveraged in a smart city to obtain real-time data about municipal operations. The idea is that a more accurate and up-to-date data snapshot of the city can be used to improve the quality of municipal services and optimize costs and resource utilization. These solutions are particularly attractive in densely populated areas, where the cost overhead of deploying IoT devices and collecting and monitoring data provides high information density relative to cost. [006] However, there are a number of challenges with smart city initiatives (or in smart systems more generally). One such challenge is determining where and how to deploy devices, as well as managing and consolidating the vast quantity of data produced for effective analysis and use. For example, all of the devices are electrically powered, which requires a source of electricity. This in turn means that devices are generally installed on municipal fixtures with an existing source of power, such as a light pole.

[007] An example of one such prior art fixture is depicted in FIG. 1. The depicted municipal fixture (103) is in the nature of a municipal light. The depicted fixture (103) comprises a base (104) affixed to a sidewalk (106) adjacent to a street (108), with an elongated pole (105) extending vertically from the base (104). The pole (105) provides sufficient elevation to disperse illumination, allow clearance for passing pedestrians and vehicles, and inhibit tampering. Extending laterally from the pole (105) is a light arm (107). A light head (109) is attached to the light arm (107). The light head (109) contains a source of illumination (1 10). A power conduit runs through the pole (105) and the light arm (107) to the source of illumination (110), and an electric power line (1 11) is run through that conduit from a municipal power source (not depicted) to power the source of illumination (110). Typically, the source of illumination is a municipal luminaire (110).

[008] However, municipal lights have various power supply configurations, sometimes even within the same cluster of lights. This in turn requires a multitude of different, expensive power adapters to be deployed. If the lights are later rewired or the power characteristics change, all of the power supplies must be replaced. Further, each individual device on or within the fixture (103) may have different power requirements, which in turn can require a single fixture (103) to be equipped with multiple power conversion units for each device.

[009] Another problem is that even once the devices are installed and powered, to get realtime data, the devices must communicate live data as it is collected. This in turn requires network access, which is difficult and expensive to deploy and manage. Most cities are very old, and it is uneconomical to run power and network wires to every device deployed in the city. Further, the quantity of data produced by any one device is typically modest, and providing a wired data solution is expensive and wasteful.

[010] Using wireless solutions is also problematic. Although the quantity of data is often manageable through a standard short-range wireless transmission protocol, this is not always the case. Short-range wireless transmission devices have a limited transmission radius, generally measured in hundreds of feet, and up to two thousand feet at the high end. A balance must be struck between broadcast distance and bandwidth, wherein long-range transmissions have very low bitrates, and high-bitrate transmissions have very short range. This can introduce network slowdowns and dropped packets in standard wireless protocols, particularly if a particular device receives a temporary burst of activity, such as from an unexpectedly large amount of data generated at a particular device or a flood of data from other nearby devices. [Oi l] In any case, even a transmission radius of two thousand feet is too small to allow all devices in a city to communicate directly with a central server so that data can be gathered, collected, analyzed, and used in real time. Each IoT device can be equipped with a broadband wireless transmitter, such as a cellular data transmitter, but this imposes significant costs and is wasteful by providing more bandwidth that is reasonably expected to be produced by any one individual device during ordinary use.

[012] Another problem subsists in how to attach the devices and the required accompanying hardware to the fixture (103), and to communicate with new devices. For example, a typical municipal lighting pole (105) lacks sufficient suitable surfaces for attaching IoT devices, power converters, and wireless transmitters. Moreover, some of this equipment should be stored within an enclosure to minimize damage from weather and tampering. In particular, power converters must tap into the central power line (111) of the pole (105), meaning they must have access to the internal structure of the fixture (103), but a fixture (103) typically has insufficient interior volume to install the power supply. Further, each device has its own command system and communication protocol, requiring a separate communication gateway for each device.

[013] This presents additional challenges as cities upgrade older lights to newer, more energy- efficient technologies, such as LED-based light sources. Moreover, in the continued effort of reducing power utilization related to street lights, attempts have been made to reduce power usage during off-peak times, or whenever full power is not necessary. However, such solutions have been incomplete.

[014] Control over the luminaire (110) in a standard street light can be implemented via a dimming receptacle (115) atop the light head (109). The receptacles (115) are mechanical and electrical/physical interfaces to the luminaire (110) for control devices. For example, the ANSI Cl 36.41 standards define multiple interface configurations facilitating various degrees of control over the luminaire (110). These include 3-, 5-, and 7-pin interface configurations.

[015] In the simplest interface, a 3-pin configuration, the three pins provide power lines only. In the 5-pin configuration, three pins provide power and the remaining two pins provide a dimming circuit, referred to in the art as“DIM”. In the 7-pin configuration, three pins provide power, two pins provide a first dimming circuit (known in the art as“DIM1”), and the final two pins provide a second dimming circuit (known in the art as“DIM2”). One problem with the ANSI Cl 36.41 standards, particularly in 7-pin configurations, is that the dimming circuit lines are sometimes accidentally swapped. Additionally, prior art implementations have used pulse-width modulation dimming, which produces flicker when using the dimming circuits. This has led to generally unsatisfactory implementations of the standard.

[016] Another problem with the standard is that the physical dimensions limit the available form factor designs, which must be compact. This in turn limits how many components may be placed in a standard-compliant control device. This presents challenges in powering the components stored within the control device, because electronic components use low-voltage direct current (DC), but the three power pins pass through the current on the municipal line, meaning they carry alternating current (AC) at variable distribution voltages ranging from 110-480 volts AC. Thus, the components must be powered by an electrochemical cell, which produces DC power, a point-of-consumption energy sources such as a photovoltaic device or small wind turbine, or the AC power received via the municipal line must be converted to DC, and stepped down to a usable voltage.

[017] Batteries and point-of-consumption solutions introduce additional difficulties. Batteries eventually expire and must be replaced, which requires servicing. Additionally, by the nature of its location, the control device is exposed to hostile environmental conditions, which can reduce battery life. Likewise, renewable solutions cannot reliably provide power in most deployment locations, requiring battery backups. Furthermore, such solutions add additional maintenance overhead. Accordingly, these solutions are expensive and duplicative, compared to the minimal power requirements of the internal components.

[018] Likewise, using municipal power is difficult. For most of the last century, power has been supplied to cities using high voltage AC power lines, generally in the range of 138-765 kVAC, and then stepped down for industrial, commercial, and residential use, and converted to DC as necessary. This variability in voltage is provided across municipal power grids, and even within a power grid or street, is a result of various factors, such as consumer need and zoning. In any given area, distribution voltages can range between 110-480 VAC, with variances of +/- 10%, resulting in a range of 90-528 VAC.

[019] The practical consequence of these variances is that a multitude of control devices must be manufactured and stocked, one for each potential voltage. This imposes significant costs, such as stocking inventory, and tracking the voltage on any particular pole. For example, if a unit requires service or replacement, it can only be replaced by a unit adapted to convert the correct input voltage. If the service personnel are unsure of the voltage of a given pole, or accidentally use the wrong type of control device, the device may be damaged or simply not function at all.

[020] The end result is that prior art solutions have been simplistic, and simply use a photocell to detect light and, if there is sufficient ambient illumination, cut power to the luminaire using the power supply pins in the standard. The dimming control circuits defined in the standard are not used because there is no way to power the components needed to use the dimming circuit lines via the receptacle interface.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

[063] The following detailed description and disclosure illustrates by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the disclosed systems and methods, and describes several embodiments, adaptations, variations, alternatives, and uses of the disclosed systems and methods. As various changes could be made in the above constructions without departing from the scope of the disclosures, it is intended that all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

[064] Because of these and other problems in the art, described herein, among other things, are systems and methods for modifying a municipal fixture to affix endpoint devices, provide a power to such devices, and managing network traffic between and among such devices, including managing upstream transmission and efficiently propagating desired state changes through the network.

[065] The systems and methods described herein generally use a plurality of mesh radio transmitters which are configured for peer-to-peer data exchange to propagate system state changes to one or more uplink gateways. The gateways may then aggregate this data and transmit it over a wide area network to a server or server farm for processing, analysis, and other use. That data may also be viewed in real time by user devices, and instructions and commands may also be relayed to the individual IoT devices in the mesh network via such user devices. These and other features are described herein.

[066] Throughout this disclosure, the term“computer” describes hardware which generally implements functionality provided by digital computing technology, particularly computing functionality associated with microprocessors. The term“computer” is not intended to be limited to any specific type of computing device, but unless otherwise specified, it is intended to be inclusive of all computational devices including, but not limited to: processing devices, microprocessors, personal computers, desktop computers, laptop computers, workstations, terminals, servers, clients, portable computers, handheld computers, cell phones, mobile phones, smart phones, tablet computers, server farms, hardware appliances, minicomputers, mainframe computers, video game consoles, handheld video game products, and wearable computing devices including, but not limited to, eyewear, wristwear, pendants, fabrics, and clip-on devices.

[067] As used herein, a“computer” is necessarily an abstraction of the functionality provided by a single computer device outfitted with the hardware and accessories typical of computers in a particular role. By way of example and not limitation, the term“computer” in reference to a laptop computer would be understood by one of ordinary skill in the art to include the functionality provided by pointer-based input devices, such as a mouse or track pad, whereas the term“computer” used in reference to an enterprise-class server would be understood by one of ordinary skill in the art to include the functionality provided by redundant systems, such as RAID drives and dual power supplies.

[068] It is also understood to those of ordinary skill in the art that the functionality of a single computer may be distributed across a number of individual machines. This distribution may be functional, as where specific machines perform specific tasks; or, balanced, as where each machine is capable of performing most or all functions of any other machine and is assigned tasks based on its available resources at a point in time. Thus, the term“computer” as used herein, can refer to a single, standalone, self-contained device or to a plurality of machines working together or independently, including without limitation: a network server farm, “cloud” computing system, software-as-a-service, or other distributed or collaborative computer networks.

[069] Those of ordinary skill in the art also appreciate that some devices that are not conventionally thought of as “computers” nevertheless exhibit the characteristics of a “computer” in certain contexts. Where such a device is performing the functions of a “computer” as described herein, the term“computer” includes such devices to that extent. Devices of this type include, but are not limited to: network hardware, print servers, file servers, NAS and SAN, load balancers, and any other hardware capable of interacting with the systems and methods described herein in the matter of a conventional“computer.”

[070] As will be appreciated by one skilled in the art, some aspects of the present disclosure may be embodied as a system, method or process, or computer program product. Accordingly, aspects of the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a“circuit,”“module,” or“system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable media having computer readable program code embodied thereon.

[071] Any combination of one or more computer readable media may be utilized. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. Unless otherwise specified, a non-transitory medium is intended. A computer readable storage medium may be, for example, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.

[072] A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.

[073] Throughout this disclosure, the term“software” refers to code objects, program logic, command structures, data structures and definitions, source code, executable and/or binary files, machine code, object code, compiled libraries, implementations, algorithms, libraries, or any instruction or set of instructions capable of being executed by a computer processor, or capable of being converted into a form capable of being executed by a computer processor, including, without limitation, virtual processors, or by the use of run-time environments, virtual machines, and/or interpreters. Those of ordinary skill in the art recognize that software can be wired or embedded into hardware, including, without limitation, onto a microchip, and still be considered“software” within the meaning of this disclosure. For purposes of this disclosure, software includes, without limitation: instructions stored or storable in RAM, ROM, flash memory BIOS, CMOS, mother and daughter board circuitry, hardware controllers, USB controllers or hosts, peripheral devices and controllers, video cards, audio controllers, network cards, Bluetooth® and other wireless communication devices, virtual memory, storage devices and associated controllers, firmware, and device drivers. The systems and methods described herein are contemplated to use computers and computer software typically stored in a computer- or machine-readable storage medium or memory. [074] Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including, but not limited to, wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.

[075] Throughout this disclosure, the term“network” generally refers to a voice, data, or other telecommunications network over which computers communicate with each other. The term “server” generally refers to a computer providing a service over a network, and a“client” generally refers to a computer accessing or using a service provided by a server over a network. Those having ordinary skill in the art will appreciate that the terms“server” and“client” may refer to hardware, software, and/or a combination of hardware and software, depending on context. Those having ordinary skill in the art will further appreciate that the terms“server” and“client” may refer to endpoints of a network communication or network connection including, but not necessarily limited to, a network socket connection. Those having ordinary skill in the art will further appreciate that a“server” may comprise a plurality of software and/or hardware servers delivering a service or set of services. Those having ordinary skill in the art will further appreciate that the term“host” may, in noun form, refer to an endpoint of a network communication or network (e.g.,“a remote host”), or may, in verb form, refer to a server providing a service over a network (“hosts a website”), or an access point for a service over a network.

[076] Throughout this disclosure, the term“real-time” refers to software operating within operational deadlines for a given event to commence or complete, or for a given module, software, or system to respond, and generally invokes that the response or performance time is, in ordinary user perception and considered the technological context, effectively generally cotemporaneous with a reference event. Those of ordinary skill in the art understand that“real time” does not literally mean the system processes input and/or responds instantaneously, but rather that the system processes and/or responds rapidly enough that the processing or response time is within the general human perception of the passage of real time in the operational context of the program. Those of ordinary skill in the art understand that, where the operational context is a graphical user interface,“real time” normally implies a response time of no more than one second of actual time, with milliseconds or microseconds being preferable. However, those of ordinary skill in the art also understand that, under other operational contexts, a system operating in“real time” may exhibit delays longer than one second, particularly where network operations are involved.

[077] Throughout this disclosure, the term“municipal infrastructure fixture” refers to light, power, and telecommunications poles and appurtenances thereto, which are installed and used by or on behalf of cities and/or utilities and carriers to deliver utilities and services to the public. Such poles are generally installed in a row along a roadway for related purposes, such as street lighting, power lines, and/or telecommunication cables. As further set forth in this disclosure, the fixtures are generally close enough together that a collection of short-range transmitters installed on them can form a mesh network.

[078] FIG. 2 and FIG. 3 depict embodiments of a municipal fixture (103) having various devices and systems described herein. The depicted municipal fixture (103) is a municipal street light (103) similar to that depicted in FIG. 1. The depicted municipal fixture (103) comprises a base (104) attached to a sidewalk (106) adjacent to a street (108). However, the fixture may be installed in other locations, such as (but not necessarily limited to) along pedestrian walkways, hiking or biking paths, in a park or parking lot, and the like. A vertical pole (105) rises vertically above the street (108) to disperse illumination, provide clearance for traffic, and to reduce tampering. A light arm (107) extends laterally from the pole (105) over the street (108). The depicted light has been modified from that shown in FIG. 1, via an enclosure (321) disposed between the light arm (107) and the light head (109). [079] One aspect of the depicted embodiment is the use of the enclosure (321) to modify the existing municipal fixture (103) to protect and enclose certain components. Examples of such an enclosure (321) are described in U.S. Pat. App. No. 15/656,675, filed July 21, 2017, the entire disclosure of which is incorporated herein by reference, and related cases, which describe a hull enclosure (321) for use with a cobra arm municipal lighting fixture. Another example of such an enclosure (321) is described in U.S. Prov. Pat. App. Ser. No. 62/688,194, filed June 21, 2018, the entire disclosure of which is incorporated herein by reference, and which describes a universal mounting system for use with a municipal fixture, such as the municipal fixture (103) described herein.

[080] The depicted light head (109) is further outfitted with a luminaire control device (201), which in turn includes a universal power supply (21 1). The enclosure (321) may in turn comprise a power supply (361). In the depicted embodiment, a plurality of endpoint devices (351 A), (35 IB), (351C), and (35 ID) are shown deployed in the proximity of the luminaire control device (201). One such depicted endpoint device (351 A) is a pedestrian/motion sensor. Another such depicted endpoint device (35 IB) is a traffic camera. Another such depicted endpoint device (351C) is a system for detecting the presence of a vehicle, shown disposed beneath the surface of the street (108). The fourth depicted endpoint device (351D) is a configurable bar light (35 ID). These and other endpoint devices may be referred to collectively herein by the general term“endpoint device” (351) for simplicity. These and other components of the municipal fixture (103) shown in FIG. 2 are described in further detail elsewhere herein.

[081] As can be seen in the depicted embodiment of FIG. 2, the power line (1 1 1) may supply power to the power supply (361) within the enclosure (321), which in turn may power one or more endpoint devices (351 A) and (35 IB). The power supply may also supply power to the source of illumination (110) and/or to the luminaire control device (201). At the luminaire control device (201), power may be converted to direct current by a universal power supply (211). The universal power supply (211) may be used to accept as a power input the voltage and current available on the power line (111) and convert that power input to one or more standard outputs usable by the luminaire control device (201). Also, the enclosure (321) may include a power supply or power converter. The depicted luminaire control device (201) may comprise a network communication device (225) used to collect and exchange data from endpoint devices, generally using a peer-to-peer protocol in a mesh network.

[082] FIG. 4 depicts an embodiment of a system as described herein. In the depicted embodiment of FIG. 4, the system (501) comprises a mesh network (505) formed by a plurality of luminaire control devices (201), sometimes also referred to herein as nodes (201 A), (20 IB), and (201C) in wireless communication. The term“mesh network” will be understood as referring to a local network topology in which network infrastructure devices and nodes connect non-hierarchically to other nodes and cooperate to route data efficiently ffom/to clients. Mesh networks are often characterized by dynamic self-organization and self- configuration. In an alternative embodiment, a conventional network topology may be used, but a mesh network is preferred.

[083] In the depicted embodiment of FIG. 4, the mesh network (505) is formed by three nodes (201 A), (20 IB), and (201C), but this is exemplary only and there may be fewer or (in most cases) more nodes in any given mesh network (505). For sake of simplicity, the plurality of nodes will be referred to herein collectively as nodes (201) unless a specific node is described. The depicted nodes (201) communicate with each other in the local mesh network (505), and one such node (20 IB) is designated as a gateway node (20 IB) and also communicates to a wide area network (503). The depicted wide area network (503) is the public Internet, but this is exemplary only. In an alternative embodiment, the wide area network (503) may be a private or virtual private network, or another type of telecommunications network. Although the nodes (201) are capable of, and may, communicate with one another, the nodes (201) primarily communicate with one or more designated gateway nodes (20 IB). Although the gateway nodes (20 IB) are also capable of communicating with one another, in the preferred embodiment, they do not, and instead, they communicate with a server (507) as described elsewhere herein. In alternative embodiments, a different communication protocol may be implemented via the nodes (201) and gateways (20 IB), depending upon whether the transceivers of the nodes (201) are capable of mesh network communication, or if an alternative protocol is instead implemented.

[084] The depicted gateway node (20 IB) communicates over the wide area network (503) with a server computer (507). Conceptually, it is anticipated that the server computer (507) is primarily responsible for maintaining an authoritative state diagram of the current status of all managed endpoint devices (351), and the gateway nodes (20 IB) and/or other nodes (201) are responsible for local handling of individual protocols and device commands for managing and altering the state and functions of the various endpoint devices (351). Shifting this function to the gateway nodes (20 IB) or other nodes (201) has the additional advantage of executing operational functionality proximate to the nodes (201), which achieves faster reaction time.

[085] The depicted gateway node (20 IB) may also communicate with one or more client devices (509). However, in the typical embodiment, client devices (509) communicate with the server (507) over the WAN (503), and the server (507) communicates with one or more gateway nodes (201B) in the mesh network (505). Thus, the mesh network (505) is local only and topologically separated from the WAN (503) by the gateway node (20 IB).

[086] The depicted nodes (201) of FIG. 4 are preferably not off-the-shelf network hardware, but rather customized devices. The depicted nodes (201) may comprise a radio transceiver (225), a processor or controller (221) operatively coupled to the radio transceiver (225), and a memory (223) operatively coupled to the processor (221). The memory (223) generally contains program instructions, scripts, and local storage. The program instructions are executed by the processor (221) to operate the transceiver (225). A node (201) may comprise one or more additional components, inputs, and outputs, including, but not limited to, a power supply, as further described elsewhere herein.

[087] In use as the nodes (201) of a smart city embodiment, each of the depicted nodes (201) is disposed at a corresponding municipal fixture (103A), (103B), and (103C). For sake of simplicity, the municipal fixtures will be referred to herein collectively as fixtures (103) unless a specific fixture (103 A), (103B), or (103C) is described. The depicted fixtures (103) are street lighting poles, but this is exemplary only and alternative fixtures may be used in an embodiment. Such alternatives may include, but are not limited to, signage, buildings and structures, bridges and overpasses, traffic control signals, electrical poles and fixtures, telecommunications poles and fixtures, railings and handrails, awnings, bus and train stops or stations, trees and plants, benches and trash receptacles, or any other municipal fixture that would not ordinarily be significantly moved or relocated. In an alternative embodiment, one or more nodes (201) may be affixed to a vehicle or other movable object, such as city vehicles or equipment (e.g., to track where they are, or how they are used), or in transit vehicles (e.g., to track movement and utilization). In a still further embodiment, a node (201) may be affixed to a microtransit vehicle, such as a motorized scooter or bicycle.

[088] In the depicted embodiment, a municipal light (103) is modified by a housing adapter or enclosure (321), including a power supply (361). The depicted power supply (361) is configured to provide electrical power to other components from the power line (111). The municipal lights (103) may be thus modified by attaching the enclosure (321) to the end of the light arm (107), installing a power supply (361) in the housing (321), and attaching endpoint devices (351) to the modular power supply enclosure (321).

[089] It will be clear that in an alternative embodiment using another type of fixture, the particular configurations of these structures may differ. For example, if a node (201) is installed on a traffic control light, a different type of adapter may be necessary to provide an attaching point for the node (201). Similarly, if a node (201) is installed on a fixture without a power source, then the configuration of the power supply (361) may differ. For example, a chemical cell or renewable power source may be required.

[090] In the depicted embodiment of FIG. 4, at least one of the municipal lights (103) has affixed thereto an endpoint device (351B), (351D), or (351F). The endpoint device (351) is typically an input and/or output device in the broadest sense, providing either communication to those present nearby or collecting input from the locality. By way of example and not limitation, the depicted endpoint device on a first municipal light (103 A) is a traffic camera (351B). The depicted endpoint device (351D) on a second municipal fixture (103B) is a bar light (35 ID). The depicted endpoint device (35 IF) on a third municipal fixture (103C) is a rain sensor (35 IF). These endpoint devices may themselves contain network hardware and communicate in the mesh network (505) by wireless transmission, or may be wired to the node (201) associated with the municipal fixture (103) and provide data to the node (201), which then provides the data on the mesh network (505). In either event, the endpoint device is conceptually similar to an IoT device.

[091] An IoT device generally is a device or product whose primary purpose or function is generally unrelated to network communications (e.g., a traditional“dumb” device), but which is enabled for network communication regardless, in order to share and exchange data and information for remote monitoring, access, and control. The depicted endpoint devices (351) may be IoT devices themselves, but an advantage to the present systems and methods is that it does not matter whether a given endpoint device (351) is IoT-ready, because the device can be connected to the corresponding node (201) on the municipal fixture (103) via the housing (321), communicate with the corresponding node (201), and use the transceiver (225) of the corresponding node (201) for IoT functionality. [092] A non-limiting example may illustrate the point. In the depicted embodiment of FIG. 4, a configurable bar light (35 ID) is affixed to a fixture (103B). This light (35 ID) may be an out- of-the-box, off-the-shelf light (35 ID) with no network connectivity, though its hue, intensity, and other characteristics may be altered or changed. The light (35 ID) may be powered by the power supply (361) or a power supply (211) of an associated node (20 IB), and connected to the associated node (201B) via the enclosure (321). Thus, whether or not the light (351D) is an IoT device, it can be controlled by the node (20 IB). The node (20 IB) is part of the mesh network (505), and the mesh network (505) has access to a WAN (503) through a gateway node (20 IB). In this example, the gateway node (20 IB) is also the corresponding node (20 IB) to the endpoint device (351D). Thus, the node (201B) can relay instructions and data pertaining to the endpoint device (35 ID) to and from servers (507), client devices (509), or other nodes (201) via the mesh network (505) alone, via the WAN (503) alone, or, in most instances, a combination of the two. For example, the corresponding node (20 IB) happens to be the gateway node (20 IB) in the depicted embodiment and so it can directly communicate with the WAN (503) for data exchange with the depicted server (507) and/or client devices (509). The corresponding node (20 IB) can also communicate over the mesh network (505) with the other two depicted nodes (201 A) and (201C). Alternatively, for an input endpoint device (351), this data flow is effectively reversed, from the device (351) to the gateway (20 IB) to the server computer (507).

[093] In another non-limiting example, endpoint device (35 IB) is a traffic camera, which again may be an out-of-the-box, off-the-shelf camera, which may or may not have network connectivity. Whether or not the camera (35 IB) is an IoT device, it can be controlled by the node (201 A). The node (201A) is again part of the mesh network (505), which has access to a WAN (503) through the gateway node (201 A). In this example, the gateway node (20 IB) is not the corresponding node (201 A). Thus, in this instance, the camera (35 IB) can send and receive data with its corresponding node (201 A), which communicates over the mesh network (505) with gateway node (201B), which can then communicate over the WAN (503) with servers (507), client devices (509), and other machines on the WAN (503).

[094] Also, the node (201 A) can communicate directly with another node (201C), or indirectly by routing through the gateway node (20 IB). Although only three nodes are shown, it will be understood that the corresponding node (201 A) could be an edge node in the mesh network (505), and may be outside the transmission range of the gateway node (20 IB). In this case, an edge node (201 A) could communicate with other nodes in range, and rely on those nodes to route communications to and from the gateway node (20 IB). This allows for a large number of nodes in the mesh network (505) to spread across a wide geographic region, including in an urban area with high-rises that may block or inhibit wireless communications, and to route communications around such obstacles.

[095] The endpoint devices shown in FIG. 4 are non-limiting and exemplary, and a variety of different devices could be used in an embodiment. Examples include, but are not limited to, parking monitoring devices (e.g., sensors to monitor whether a parking space is occupied, such as magnets, optical sensors, proximity sensors, etc.), pedestrian sensors, occupancy sensors, structural sensors (e.g., devices which monitor vibrations and material conditions in buildings and infrastructure), bridge sensors, noise sensors, light sensors, smartphone detection, cameras, traffic monitoring and sensors, street lighting, waste management, fire sensors, smoke detectors, air pollutant sensors, pollen sensors, snow accumulation sensors, weather sensors, rain sensors, water level sensors, earthquake sensors, landslide and avalanche sensors, environmental sensors, carbon dioxide sensors, water quality and/or purity sensors, chemical sensors (e.g., to detect air or water pollution or leakage), water flow sensors (e.g., to detect blockages or rubbish in waterways), light sensors, digital banners, visibility distance sensors, sea level sensor, wave and tidal sensors, water main sensors, water pressure or speed sensors, hazardous or explosive gas or material sensors, radiological sensors, optical and infrared cameras, smart trash bin sensors, and so forth.

[096] In the depicted embodiment, the plurality of nodes (201) communicates commands associated with the endpoint devices (351) over the mesh network (505) to one or more gateway nodes (20 IB). Each gateway node (20 IB) may then communicate this and other data with a server (507) over the WAN (503). The gateway node (20 IB) may also receive instructions over the WAN (503), from a server (507), from a client device (509), or from another source. The instructions generally comprise requests for information or data pertaining to one or more endpoint devices (351), or commends to control one or more endpoint devices (351).

[097] The systems and methods described here may be used in an embodiment to propagate external instructions through the mesh network (505). This may be done by a user of a client device (509) providing instructions to the server (507), which then relays those instructions over the WAN (503) to one or more gateway nodes (20 IB). The gateway node(s) (20 IB) then relay(s) instructions to all other nodes (201A) and (201C) in the mesh network (505).

[098] This may be further understood through a non-limiting illustrative example. Suppose that the municipal fixtures (103) are municipal street lights and that each light is equipped with a configurable bar light device (35 ID). The city in question has multiple sports teams or colleges with different team colors and desires for the bar lights (35 ID) to be the color of one specific team on days when that team is playing a game (e.g., red), and to be the color of a different team on days when that team is playing (e.g., blue). On days when no team is playing, the city wishes for the lights (35 ID) to be white. Rather than physically visit each municipal fixture (103) to adjust the color, the systems of FIG. 4 may be used to provide instructions.

[099] A user, generally a person associated with the city or a relevant department thereof (e.g., streets, tourism, sports commission, etc.) will use an authorized client device (509) to connect to a server (507). Typically, the authorized client device (509) is a computer running a web browser or other web interface to connect to the server (507). The server is in communication with one or more gateway nodes (201B) in the mesh network (505) formed by the nodes (201) associated with each bar light (35 ID). The user provides instructions to the client device (509) via a user interface to change the light shade to blue. This may be done using any appropriate interface, such as a color wheel, manually providing red-blue-green (RBG) values or other color codes or values, and so forth. The client (509) then communicates these instructions to the server (507) over the WAN (503). The server (507) then communicates these instructions to the applicable gateway node(s) (20 IB). The gateway node(s) (20 IB) then use the mesh network (505) protocol to distribute the instructions across the mesh network (505) to the other nodes (201). All nodes (201), including the gateway node(s) (201B), then operate the connected light bar (35 ID) to change its color to blue as instructed.

[100] It will be clear that security procedures and protections are needed. For example, if the communication protocol for the mesh network (505) is known, an unauthorized third party could use a wireless device to spoof an instruction to one or more nodes (201), and thus provide unauthorized instructions to an associated endpoint device (351). Similarly, an unauthorized third party could spoof a device (351), node (201), or gateway (20 IB), and provide false or unauthorized data to the server (507). To inhibit such tampering, the mesh network (505) may use a data exchange protocol encrypted via a private key, as well as asymmetric cryptographic key algorithms for device and gateway identity validation. Similarly, the gateway (20 IB) may use an encrypted communications technique, such as a secure sockets layer, virtual private network, or other secure networking protocol.

[101] Additionally, and as further described elsewhere herein, a“snapshot” of the system state may be stored and used to periodically update endpoint devices (351). For example, the server (507) and/or one or more gateway nodes (20 IB) may maintain a stored copy of the desired current system state, based on the most recently received user instructions. The gateway (20 IB) may then periodically“check in” with the nodes (201) to confirm that the associated endpoint devices (351) have the correct settings and, if not, instruct the node (201) to configure the device (351) with the correct settings. The frequency of these“check-ins” may vary by endpoint device (351) type. For example, where the endpoint device (351) is a light bar, the consequences of an improper setting are generally not severe (a light may be off or have the wrong color), and it is less urgent to check in frequently. However, where the endpoint device (351) is a security or traffic camera, the frequency may be greater to ensure that the camera is properly configured, focused, and oriented to monitor the area. Thus, even if an unauthorized third party were to break into the system and provide spoofed instructions to a device, the error would be corrected in due course because the unauthorized third party cannot access or change the stored system state data, which is used to correct endpoint devices (351) with errant settings.

[102] In an embodiment, methods for detecting errant behavior may comprise the use of acknowledgements. Such acknowledgements may take the form of the current state accompanied by a checksum, which is sent to one or more gateways (20 IB). Each such gateway (20 IB) has data concerning whether a particular command (e.g., instructing the settings of an endpoint device (351)) was successful. In the event that an endpoint device (351) received a command from an unauthorized or malicious external source, the endpoint device (351) would be programmed via the communications protocol to report the commanded state change from that source to its designated gateway (20 IB) in the form of an acknowledgement of the command. However, the gateway (20 IB) would have knowledge that it issued no such command, and could thus verify that the requested change was not actually requested via the system, and instruct the errant device to correct its state back to the stored state tracked by the gateway (201B) or the server (507). A checksum may be utilized to quickly assess whether the state is correct. That is, a checksum may be calculated to be representative of the intended or current device state. After the application of a delta (discussed in more detail elsewhere herein), a new checksum will be calculated and compared to the prior checksum. If they differ, then the system knows that a requested change was missed or an unauthorized change was executed, and resynchronize the system by transmitting a full copy of the device state to all nodes (20 IB), which can then provide appropriate command instructions to the endpoint devices (351).

[103] As will be understood by a person of ordinary skill, the server (507) may be a single server, but it is more common for multiple servers to coordinate or collaborate to respond to requests to ensure timely responses. These multiple servers function as a single logical server (507), and the particular server selected to handle any one request may be determined using any number of techniques, such as by use of a load balancer.

[104] To improve efficiency and minimize network bandwidth utilization, in an embodiment, the communications protocol in the mesh network (505), and/or between the gateway nodes (201B) and server (507), and/or among multiple server instances (507) forming a logical server, may operate on a“delta” basis. That is, when an instruction is received to alter the system state, only the deltas need be transmitted. By way of example and not limitation, if an instruction is received to change light bars to blue, but make no changes to intensity, there is no need to relay data about intensity, and only the delta between the current state and the desired state need to be communicated. This reduces the transmission of superfluous data, increases response time, and reduces bandwidth consumption.

[105] Additionally, in an embodiment, endpoint devices (351) are treated as an abstraction and each type of endpoint device (351) has an associated format of expected data that may be sent to or received from the device. For example, a light bar type may have expected RBG and intensity values, but no orientation data. Thus, if an instruction is received for a light bar device that includes orientation data, the instruction can be quickly rejected and not propagated through the system, because it is formatted incorrectly for the device type. This is typically done at the server (507) but could also be done elsewhere in the system to prevent improper data from being unnecessarily transmitted, such as at the gateway node (20 IB), client (509), or any other nodes (201). The device type data format facilitates the data delta system described herein to operate efficiently by facilitating the elements of the system removing redundant data and communication with other elements of the system which already have the same information. In an embodiment, this may be performed at essentially each step of the data flow. Thus, if incorrect data is identified, it can be used to attempt to correct the system state and resolve conflicting deltas. Further, in an embodiment, it can be used as a flag for possible intrusion detection or attempted instruction by identifying endpoint device (351) behaviors or data values which are inconsistent with the expected behaviors and values based on the stored system state in the master record.

[106] The overall framework for this system functions as a communication library for connecting devices. That is, the server (507) and gateways (201B) are programmed with a cohesive communication framework which tracks the system state and provides communications as necessary through the mesh network (505) to set devices to the desired state, or acquire desired data, and to do so in a device-agnostic fashion. This is done by abstracting each device in memory as a collection of data and states. When a new endpoint device (351) is desired to be added to the system, the endpoint device (351) itself may have its microcontroller or other programming modified to include a communications library for interoperating with the systems and methods described herein. Likewise, the communications library implemented via the server (507) and the gateways (20 IB) may also be modified to recognize the new type of endpoint device (351) throughout the system. However, because the communications layer is uniform, the operation of the system does not require further modification to accommodate new types of endpoint devices (351). [107] In an embodiment, the systems could be used to coordinate a performance among a plurality of lights. For example, a series of light poles (103) on a block or street could each be outfitted with a multi-color light tube controlled by a luminaire control device (201) described herein. A sequence of illumination instructions could be programmed so as to cause each luminaire (110) (or a second luminaire (117), light bar, or other device) to illuminate in a sequence and timing to present an image when viewed from a given perspective or angle. By way of example and not limitation, the luminaires (1 10) could present the impression of a national flag, such as the U.S. flag. Each luminaire (1 10) could also be operated to animate the flag, such as to simulate a“waving” effect. The luminaires (1 1) could also be coordinated to music so as to present a multimedia presentation.

[108] Also described herein is a luminaire control device for use with a municipal light pole. The device is plugged into a standard dimming receptacle and includes a universal power supply for converting AC power received in any of the common municipal distribution voltages to a uniform DC output usable by small electronic components of an accompanying control system. The universal power supply and control system are configured to fit within the form factor required by applicable standards. The control system includes program logic to control the luminaire by sending control signals via the dimming receptacle. These signals may be sent using one, two, or more control channels as defined by the standard, and may control a single luminaire or multiple luminaires via the different channels. The device may further include a wireless transceiver to facilitate remote access and control of the light, allowing a municipal light pole to be retrofitted as an IoT device.

[109] Described herein, among other things, is a luminaire control device (201) including a universal power supply (21 1) and control system for use on a municipal infrastructure pole (103). FIG. 5 depicts a basic diagram of a device (201) as described herein. At a high level of generality, the luminaire control device (201) depicted in FIG. 5 can be thought of as having three main components: a housing (203) and (205), a power supply (21 1), and a control system (207). When the device (201) is further outfitted with a wireless communication system as part of a network of similar devices in a deployment, it may sometimes be referred to in shorthand as a“node” or“beacon.”

[110] The depicted housing comprises a base (203) and an enclosure (205) adapted to plug into a dimming receptacle (1 15) and enclose a power supply (211) and control system (207). The depicted control system (207) is adapted to control one or more luminaires (1 10), and the depicted power supply (21 1) is adapted to receive municipal electrical power in any of the commonly provided voltage ranges and convert that power into a uniform DC output suitable to power the components of the control system (207). Both of these elements (21 1) and (207) are adapted and arranged so as to fit within the enclosure (205), which is in turn adapted to the form factor of the base (203), and are further described elsewhere herein.

[111] The form factor of the housing elements (203) and (205) may be defined or limited by the specifications of an applicable standard. For purposes of the exemplary embodiments described herein, that standard is ANSI 036.41. In an embodiment using the ANSI 036.41 standard, there may be 3-pin (power only), 5-pin (3 power pins plus one 2-pin dimming circuit), and 7-pin configurations (3 power pins and two 2-pin dimming circuits). In an alternative embodiment, the base (203) or other elements may comport with different standards or requirements as may be needed for the particular embodiment.

[112] The depicted base (203) is a generally circular element made from a rugged, weather- resistant material to extend operational life and provide a suitable surface for supporting other elements. Generally, the base is sized and shaped to comport with the applicable standard for receptacles or sockets on a municipal light. As described elsewhere herein, the depicted base (203) is sized and shaped for use with a receptacle in compliance with ANSI 036.41. [1 13] The depicted enclosure (205) is a roughly cylindrical dome sized and shaped to accommodate the interior components of the device (201) described herein. The enclosure (205) has an open bottom end adapted to mate with the base (203) so as to form a sealed connection. The sealed connection should inhibit or prevent moisture penetration. Because the device (201) will ordinarily by used outdoors on a street light, it is desirable to endure outdoor weather conditions in most climates. The enclosure (205) should be manufactured from a rugged, water-resistant or waterproof material which can withstand liquid and solid precipitation, high winds, impacts from debris, and so forth. The enclosure (205) may be opaque, transparent, or translucent. A generally cylindrical enclosure (205) is shown but other sizes, shapes, and configurations of enclosures (205) are possible, including but not limited to enclosures (205) which have an orthogonal or prism configuration.

[114] The particular configuration will generally depend on the shape of the base (203) to which the enclosure (205) attaches and the size and shape of the internal components. In certain embodiments, the enclosure (205) may further comprise one or more openings or apertures to allow some or all of the internal components to be disposed external to the enclosure (205). By way of example and not limitation, if an internal component is a wireless communication apparatus which includes an antenna (227), it may be desirable to dispose the antenna outside of the enclosure (205) for greater range. Thus, a water-resistant or watertight opening (229) in the enclosure (205) may be provided for this purpose.

[115] In the depicted embodiment of FIG. 5, the base (203) has seven conductive elements to establish an electrical connection via the receptacle (1 15). These comprise three power transmission connections in the form of prongs (209) disposed in a circular twist-lock arrangement extending generally perpendicularly from the bottom of the base (203), and four functional inputs in the form of spring contacts (213). The depicted prongs (209) are sized, shaped, and arranged for plugging into the dimming receptacle (1 15) and provide a current path for electrical power (i.e., AC current) from the municipal power line (111) in the pole (105) to be provided to the power supply (21 1) as described elsewhere herein.

[116] The particular size, shape, and number of prongs (209) may vary from embodiment to embodiment and will depend upon the particular configuration of the dimming receptacle (115) for which the device (201) is designed to interoperate. Generally, the prongs (209) comprise two hot lines and a neutral line and are electrically connected to the power supply (211).

[117] The four depicted spring contacts (213) are for central circuits, or dimming pins, and are disposed in the positions on the bottom of the base (203) specified in the applicable standard. This allows the depicted device (201) to be used in a standard receptacle (115) to, for example, control light intensity, reduce power consumption, or perform other functions as described elsewhere herein. The contacts (213) are generally electrically connected to components of the control system (207). The depicted four dimming inputs (213) comprise various dimming command lines as defined by applicable standards. In an embodiment, the Digital Addressable Lighting Interface (DALI) standard may be used. These inputs generally do not connect directly to the power supply (211), but rather pass through to the control system (207) and are controlled by components disposed thereon.

[118] By way of example and not limitation, this relationship is shown in FIGs. 10, 11, and 12 with respect to the spring contacts (213). Also by way of example and not limitation, a standard may implement a 0-10 volt analog interface to indicate desired light intensity. A 10- volt signal indicates maximum light intensity and 0 volt signal indicates“off’ or no light intensity. In the depicted embodiment, the two pairs provide two separate channels of control, referenced to as the“dual channel” aspect.

[119] The depicted contacts (213) are arranged into pairs and each pair connects via the receptacle (115) to a different dimming driver within the luminaire (110) structure. Thus, each pair can be separately commanded or operated to control the luminaire (110) by components, circuitry, and logic in the control system (207).

[120] The power supply (21 1) is designed and laid out so as to fit within the form factor of the housing (203) and (205), and comprises all components required to adapt the range of power conversion described herein, and leave sufficient surplus volume within the house (203) and (205) to accommodate a control system (207) and/or other components. FIG. 8 provides a schematic diagram of an embodiment of a power supply (21 1) implementing power conversion from a range of 90-528VAC to 12VDC. For example, header P8 provides the connection to route various electrical lines (e.g., to the control PCB/control system (207)). The current sensing function is at pin 7, PI (DIM1+) is at pin 3, P2 (DIM1 -) is at pin 5, P3 (DIM2+) is at pin 4, P4 (DIM2-) is at pin 6, and a load switch to the relay is at pin 8 of header P8. A device (201) having a form factor compliant with the applicable standards requires small components, yet must also step down voltage as high as 528 VAC to 12 VDC to operate a small electrical load in excess of 1 W, as high as 4 W, and preferably about 3 W to 3.3 W. In particular, the form factor defined by the ANSI standard is generally too small to allow the inclusion of all electronic components required to both convert all ranges of voltage commonly found in a municipal light pole power line, as well as fit a control system (207) and other desired components. Prior art components of appropriate size to be fitted within the device (201) form factor lacked the ability to provide power conversion in this range by a significant margin.

[121] To achieve the required form factor, a transformer core may be custom wound to achieve a desired isolation voltage range within the volume or size limitations imposed by the standard. Additionally, or alternatively, a particular circuit layout may be used to minimize the physical footprint of the power supply (211 ) so as to fit within the form factor. The depicted embodiment of FIG. 8 has a small enough footprint to be contained within the form factor of the ANSI standard, while also accommodating the control system (207). [122] The depicted device (201) of FIG. 5 can accept as power input any range of AC current between about 90 and 528 VAC and convert this power input into a consistent level of DC power output. The specific power output may vary from embodiment to embodiment depending upon the power requirements of the associated device to be powered. In the typical embodiment, such as that in which the control system (207) is for controlling a luminaire (110), the power output is about 12 VDC. In a further embodiment, the power output is at least 12 VDC. In a further embodiment, the power output is at least 12 VDC at 140 mA, or about 1.7 W at 12 VDC. In a further embodiment, the average operational capacity is at least 12 VDC at 170 mA, or about 2.0 W at 12 VDC.

[123] In certain embodiments, it may be desirable to have systems and/or apparatus for identifying differing power supply bases. By way of example and not limitation, it may be economical feasible to stock a power supply (211) for converting 90-277 VAC power, and a second power supply (21 1) for converting up to 480 VAC power. However, it is also desirable that the corresponding control system (207) be agnostic as to which power supply (211) it is packaged with, so that a single software version may be maintained, reducing development and maintenance costs. This may be done by using four pins on the headers connecting the power supply to the control system (207). One such pin would be a ground pin, and three would be signal pins. Depending on the pattern of the three pins connected to the ground line, it is possible to determine which power supply (21 1) is connected to the control system (207). The other lines not connected to the ground would then be left as floating lines. It should be noted that the ground and signal lines come from the control system (207) and the power supply (21 1) may only connect the pins together in a specific pattern. Pins Dl, D2, and D3 are connected to microcontroller pins. However, in the preferred embodiment, it is desirable to use a uniform configuration of power supply (211) to minimize complexity and stocking requirements, and this element may not be used. [124] It will be appreciated that the power supply (21 1) may provide a DC power output at a particular level, but that this level may nevertheless remain too high for some uses. Thus, in some embodiments, a control system (207) may have further“step-down” components disposed thereon to further reduce the power level. For example, the control system (207) components may require power in the range of 3 to 4 VDC at 45-290 mA, or 0.15 to 0.95 W. In an embodiment, the control system (207) may comprise step-down circuitry so as to provide power to associated components in the range of 1.35 W to 4 W. In an embodiment, power is supplied at 3.3 V at 0.410 mA on the control system (207).

[125] The depicted control system (207) contains components and/or program logic or software to operate the luminaire (1 10) via one or more control channels, (231) and (233). The depicted embodiment of FIG. 6 is a seven-pin dimming receptacle (115). In an embodiment using a five-pin receptacle, the auxiliary control line (233) would not be present, and a single channel of control line (231) would be used instead. As can be seen in the depicted embodiment of FIG. 6, both control channels (231) and (233) are operatively connected to the luminaire (110) through the dimming receptacle (1 15).

[126] The control system (207) generally will comprise a circuit board and various components to perform one or more non-power conversion functions. The particular nature of these functions, and, by extension, the associated components, will vary from embodiment to embodiment depending upon the particular needs of any given implementation. Generally, it is anticipated that the control system (207) will usually comprise a processing system (221), such as a computer, microprocessor, microcontroller, controller, or other logic unit, for operating the components of the control system (207) and sending control signals on one or more of the control channels for operation of one or more luminaire(s) (1 10).

[127] Typically, the control system (207) will further comprise a memory (223) or storage (223) containing executable instructions for operating the device (201) or luminaire(s) (1 10). The control system (207) may further comprise other appropriate hardware systems and circuitry as necessary to implement the functions described herein. The control system (207) components and program logic/instructions operate the luminaire(s) (110) using control channels (231) and (233) in accordance with the needs of the given embodiment. Other components may also be included in the control system (207) or otherwise disposed within the interior of the assembled device (201) and powered by the power supply (211). These other components may include, but are not necessarily limited to, a microprocessor, a controller, a photocell or other daylight sensing technology, and/or expansion ports for other sensors.

[128] The components of the control system (207) receive power via a wired connection to the power output from the power supply (211). The particular arrangement of such a wired connection will vary from embodiment to embodiment, but typically will be consistent such that only one, or a small number, of power supply (211) configurations need be produced, and any number of different control system (207) or other powered interior components may be used with that one or small number of power supplies (211).

[129] By way of example, and not limitation, one or more of the control channels (231) or (233) could be used to alter the color temperature of the luminaire (110). Alternatively, one channel (231) could be used to control the color temperature of the luminaire (110), while the other channel (233) is used to control the light intensity of the luminaire (110). In this fashion, the luminaire control device (201) has the ability to simultaneously control multiple operational states of the luminaire (110). For example, when there is insufficient light, such as dusk, dawn, overnight, or during inclement weather, power is restored and the luminaire (110) is illuminated.

[130] In an embodiment, the control system (207) may further include a short- or long-range transceiver (225), such as, but not necessarily limited to, a radio transceiver. The transceiver (225) is preferably adapted to receive and transmit using a standard-complaint protocol over short- or long-range distances, such as via a local short-range protocol, a Wi-Fi protocol, or a long-range wireless data protocol, including but not limited to a protocol in the IEEE 802.11 family of protocols. The transceiver (225) may be used to send to or receive from remote devices information, instructions, or requests relating to control of the device (201) and/or the luminaire(s) (110) to which it is connected. Instructions received at the transceiver (225) may then be processed by a processing system (221) and control signals may be sent to the luminaire(s) (110) based on the data received via the transceiver (225).

[131] By way of example and not limitation, the control system (207) may include a mesh radio transmitter, such as that described in U.S. Prov. Pat. App. No. 62/792,213, filed Jan. 14, 2019, and U.S. Pat. No. 10,260,719, issued April 16, 2019, the entire disclosures of which are incorporated herein by reference. In this fashion, the device (201) effectively functions as an IOT device capable of being operated using the systems and methods described in the foregoing references. By including in the control system (207) a wireless transceiver and program logic for receiving, processing, and issuing command instructions to the appropriate channel wires, the luminaire (1 10) may be remotely operated over a telecommunications network using the device (201). In an embodiment, and as further described in the other applications referenced elsewhere in this disclosure, the control system (207) may include a microprocessor executing program instructions from a memory, which operate communications hardware to exchange data and instructions with other nearby devices (201). Additionally, or alternatively, this may be done to communicate over a WAN (503), including but not limited to a cellular network.

[132] Also by way of example and not limitation, the control system (207) may include other inputs and outputs, including but not limited to ports or connections for other IoT devices to be controlled by the device (201) via wireless communications as described in the above- referenced applications and elsewhere herein. Exemplary embodiments of these and other components contemplated for use with the devices described herein are also described in the above-referenced applications.

[133] As discussed in the background section, one problem with dimming receptacle standards is that prior art implementations have used pulse-width modulation dimming, which results in flicker when using the dimming circuits. To overcome this, in the embodiment depicted in FIG. 9, a potentiometer (235) may be included in the control system (207) with at least one of the dimming pin sets (237), operated by a microcontroller (239). In the depicted embodiment, the microcontroller (239) is an integrated circuit. As seen in FIG. 9, one set of dimming pins (237) is shown, but the second set (not shown) could also be wired to a potentiometer (235). In the depicted embodiment, the first dimming pin DIM- is connected to the microcontroller (239) at pin PWO (#11) in FIG. 9. This is the control line for the wiper (241) (e.g., a sliding contact on a resistive strip in the potentiometer that alters the amount of resistance in the circuit). These configurations may be used to create, in effect, a digital “control knob” within the apparatus for controlling luminaire intensity, with reduced flicker and self-correction in the event of pin misalignment.

[134] FIGs. 10, 11, and 12 depict an embodiment of a power supply (211) showing the connecting elements to the control system (207). In an embodiment, a single header is used to connect elements of the power supply (211) to the control system (207). This may be done, for example, by connecting a cable (217) from the control system (207) to the header. In an alternative embodiment, the connecting elements may comprise two rows of headers. That is, the“stack” in the device (201) is ordered, from bottom to top: base (203), then power supply (211) on top of the base (203), and then one or more control systems (207) on top of the power supply (211).

[135] In an embodiment, the number and arrangement of headers may be selected to provide mechanical stability for elements disposed above the power supply (211), including but not necessarily limited to a control system (207). In the depicted embodiments, the rows of headers comprise rows of 0.1” headers, but this is exemplary only and not necessarily limiting. It is specifically contemplated that a single header may suffice in the preferred embodiment.

[136] In an embodiment, at least one of the headers is a conductive signal-carrying element. It is contemplated that at least two pins each of 12 VDC power and a ground line are provided for redundancy to ensure power flow in the event of a mechanical failure of one set of pins. Thus, in the preferred embodiment, at least four pins are devoted to power transmission from the power supply (211) to a control system (207). However, in other embodiments, there may be more (or less) pins having this function.

[137] In an embodiment, at least one header pin provides another function. By way of example and not limitation, a pin may provide signals pertaining to dimming. That is, a controller on the control system (207) may relay signals via the pins to the luminaire to which the device (201) is attached to control dimming functions. Additionally, or alternatively, wires for transmitting dimming controls or instructions may by connected directly to pins on the plug and carried directly to the control system (207). Such wires are not necessarily power supply lines but rather function effectively as a bus, and thus may bypass the power supply (211).

[138] In the depicted embodiments, the components on the control system (207) are in turn powered by the adjusted power output at the appropriate voltages produced on the power supply (211). The device (201) may further include mechanical struts or supports to provide stability and separation between the power supply (211) and the control system (207).

[139] FIG. 6 depicts an embodiment of the municipal luminaire control device (201) installed on a light head (109) containing a luminaire (110). As can be seen in the depicted embodiment of FIG. 6, the luminaire (110) is enclosed within the light head (109), which is attached to a light arm (107). In the depicted embodiment, an enclosure device (321) is installed in-line between the arm (107) and light head (109). The municipal luminaire control device (201) is plugged into a dimming receptacle socket (115) on the dorsal side of the light head (109). A municipal power line (111) is disposed within the arm (107) and passes through the enclosure (321) to power the luminaire (110). This line (111) is connected (113) to the power supply interface in the dimming receptacle (115), as defined by the applicable standard.

[140] When the luminaire control device (201) is attached to the receptacle (115), an electrical connection (243) is formed between the power line (111) and the power supply (211) inside of the device (201). The power supply (211) receives alternating current from municipal power line (111), converts it to direct current and steps down the voltage to an amount useable by the control system (207). The resulting direct current is indicated in FIG. 6 as a wired connection (245). The components of the depicted control system (207) are then powered by the direct current received (245) from the power supply (211).

[141] In an alternative embodiment, such as that depicted in FIG. 7, the luminaire control device (201) may be used to control two different luminaires (110) and (117). In the depicted embodiment of FIG. 7, a first luminaire (110) is contained in the light head (109) in a similar fashion as described with respected to FIG. 6, but a second luminaire (117) is disposed elsewhere on the municipal infrastructure pole (103). In this embodiment, the primary channel (231) (e.g., DIM1) may be used by the luminaire control device (201) to operate the primary luminaire (110) in the light head (109), while the auxiliary control channel (233) (e.g., DIM2) may be connected to the second luminaire (117) to control that luminaire (117) instead. In the depicted embodiment, for example, the first luminaire (110) is a traffic luminaire disposed above a street to illuminate the surface below for traffic safety, while the second luminaire ( 117) is disposed next to the sidewalk to provide illumination and safety to pedestrians adjacent to the street. In this fashion, the luminaire control device (201) can independently operate both luminaires (110) and (117) in accordance with the operational needs of the implementation. [142] In an embodiment, both the DIM1 and DIM2 commands are used to control a single luminaire (110). By way of example and not limitation, DIM1 may be used to control a first aspect of the luminaire (1 10) and DIM2 may be used to control a second aspect of the luminaire (110).

[143] In an embodiment, one or more of the luminaires (110) and (1 17) may be adapted or designed to respond to specific commands issued via the control channels (231) and (233). The specific nature of this design will depend upon the needs of the implementation. By way of example, and not limitation, if the design is intended to provide variance in light intensity, then the luminaires (110) and (117) may be designed to alter light intensity in response to commands or voltages received via the channels (231) and (233). It should be noted that in the depicted embodiment of FIG. 7, the enclosure (321) is omitted for illustrative simplicity.

[144] In an embodiment, a specialized luminaire (1 10) may be used, which may be specifically adapted to accept and respond to commands issued via the dimming receptacle. That is, although the receptacle is intended for a dimming function (e.g., by use of a photocell to detect sunlight and dim the luminaire (1 10) when there is sufficient ambient light that use of the luminaire (1 10) is unnecessary), the standard defines a mechanical and electrical interface which can be used to transmit any number of types of instructions via the control channels (231) and (233). For example, an LED light fixture may be programmed to respond to commands received on DIM1 and/or DIM2 (or just on DIM).

[145] Alternatively, an existing light head (109) may be retrofitted without the necessity of installing a new luminaire (110). For example, the device (201) is installed in a dimming receptacle atop a street light (103) to replace a photo control cell. The device (201) may itself include a photocell and receive a signal from that photocell which is also used to control the luminaire (1 10), and/or may operate the luminaire (110) in accordance with other criteria depending upon the function of the control system (207). [146] An improvement over prior art devices is that the ballast drivers may not fully implement“turning off’ the luminaire (110). For example, a“1-100” driver is configured to set the light intensity to between 10% of maximum intensity and 100% of maximum intensity. Thus, if a control signal received on PI, P2, P3, or P4 indicates a voltage of zero, meaning a command to cut the light entirely, the ballast driver may nevertheless maintain the luminaire (110) at 10% light intensity. This in turn means that, in a prior art device in which a photovoltaic cell is installed, even with full sun in broad daylight with a 0 volt command signal to the driver, the driver maintains the light on at 10% power, wasting electricity. In one embodiment of the present device, the power supply (211) and control system (207) may implement command logic which cuts line power to the driver entirely, thus ensuring that no power is wasted by a 1-100 driver forcing the luminaire (110) to 10% intensity regardless of the analog control signal.

[147] The luminaire control device (201) described herein may be used to control functions beyond dimmable controls. For example, in an embodiment, the luminaire control device (201) may utilize one or both channels to provide various instructions and functions to the luminaire (110). The particular functions of each channel may vary from embodiment to embodiment while remaining within the requirements of the applicable standard. By way of example and not limitation, the signals transmitted over the control lines may alter the color temperature of the light. In one embodiment, DIM1 may control the 4000 Kelvin temperature range, and DIM2 may control the 6000 Kelvin temperature range. Thus, by increasing DIM1, the color tone of the light becomes more yellow, and by increasing DIM2, the color tone of the light becomes more white. This, in combination with the potentiometer implementation, facilities a smooth gradient of light temperature.

[148] The depicted design has the advantage of being able to receive any amount of municipal voltage commonly distributed in the United States and convert that voltage to a uniform output for use by the control system (207). This allows a single luminaire control device (201) to be manufactured and stocked for any given implementation, and avoids the need for the city to manage a stockpile of multiple devices (201) accepting different voltages, and to monitor and track which poles in a given power grid operate at which voltages. Utility crews may simply pick up a device (201) and install it in any pole, and be confident that the voltage will be accepted, converted, and usable without damaging the device (201). This design also has the advantage of directly utilizing the municipal power supply (111) without the need to include batteries, or photocells, or other solutions which cannot provide a consistent amount of power, resulting in the control system (207) being potentially unpowered and either malfunctioning, or failing to operate the luminaires (1 10) correctly. Additionally, by utilizing both control channels (231) and (233), multiple aspects of a single luminaire (110) may be controlled by a single device (201), or multiple luminaires (110) may be independently controlled.

[149] Also described herein are systems and methods for providing“localization” of moving objects (e.g., people, vehicles, equipment) by using beacons installed on municipal fixtures (103), such as light and utility poles. The beacons transmit, in the ordinary course of network communication, an identifier. Because the fixtures (103) do not move, the fixed geographic locations of the fixtures ( 103) can be associated in a database with a unique identifier broadcast by the beacon installed on the fixture (103). When a moving device having a wireless transceiver approaches the fixture (103), it will receive transmissions from the beacon including the identifier, and can then look up the identifier in the database to get the geographic coordinates. This can be done even without the moving device’s wireless transceiver authenticating or connected to the beacons’ network. This location can then be used for a wide variety of applications and purposes.

[150] As shown in the depicted embodiment of FIG. 13, the luminaire control device (201) may also be used for a number of other purposes, and may incorporate other components to facilitate other functions unrelated to the luminaire control system (207). For example, the control may be designed and/or programmed with circuitry and/or computer logic to a wide variety of functions in addition to those described in this disclosure. As described in other patent applications referenced elsewhere herein, the device (201) may be one of a plurality of devices in a network of similar devices, some or all of which may be equipped or otherwise connected with one or more sensors on or at a utility pole (103). The data detected by the devices (201) may be collected and shared via a wireless network among such devices (201), including but not necessarily limited to a mesh network (505). This data may be used to “localize” where specific incidents or types of incidents have taken place. This data may be provided to municipal authorities, emergency responders, and/or the general public or private parties for use, processing and consumption. The data may be used, for example, in a consumer/end-user software application.

[151] In an embodiment, a short-range radio transceiver (1011), or“beacon,” would be installed on some, most, or all of the devices (201) in a given deployment. This may be done by including the beacon (1011) in the control system (207), for example. Such beacons (1011) could be, but are not necessarily limited to, radio transceivers using a wireless communication protocol in the IEEE 802.11 family of protocols, or some other protocol. Examples of suitable protocols include Bluetooth™, WiFi, Ultra-wideband, ISM (Industrial, Scientific, and Medical) bands, and other radio types. In an embodiment, a beacon (1011) may be enclosed within the device (201) or attached in a different location, such as in a photocell or other device using the dorsal receptacle (115), behind the luminaire (110) in an enclosure, or using a Zhaga Book 18 connection.

[152] Such beacons (1011) commonly include a unique, or semi-unique, identifier (1015) which is broadcast with ordinary transmissions as part of the wireless communication protocol. This identifier (1015) helps other devices within broadcast range identify the source of a given wireless signal or data packet. A database (1013) could be assembled which associates, for each unique identifier (1015), a geographic location (1017) where the beacon (1011) having that identifier (1015) is installed (e.g., the geographic coordinates (1017) ofthe light pole (103) into which a luminaire control device (201) containing the beacon (1011) is plugged). This database (1013) could be stored and accessed locally (e.g., on a mobile device (1003), vehicular telematics system (1004), etc.) or hosted remotely for query/access (e.g., the mobile device (1003) or vehicular telematics system (1004) transmits the beacon identifier (1015) to the remote hosted database (1013), and the database (1013) returns the geographic coordinates (1017) for that beacon identifier (1015)).

[153] To locate a given device (1003) or (1004), the device (1003) or (1004) receives the identifier (1015) for one or more beacons (101 1) and looks up (locally or remotely) the associated geographic coordinates (1017). The location of the device (1003) or (1004) can then be approximated to varying degrees of precision. Techniques for doing so include received signal strength indicator analysis, angle of arrival using phased antenna arrays, and other techniques known in the art. The location information calculated can then be used to replace, supplement, or augment other location technologies.

[154] Any number of applications could be programmed or developed to take advantage of this increased accuracy. These include but are not necessarily limited to vehicular navigation and assistant technologies such as lane assist, GPS navigation assistance, routing, autonomous vehicle location and piloting, and traffic flow analysis. Other exemplary applications include managing small or shared commuter vehicle fleets such as bicycles and e-scooter pools, where the location data may be used to geofence the range of the fleet to prevent operation outside of permitted areas. This reduces the need to rely on GPS transmitters, which drain battery life and shorten the operational life of e-scooters. [155] The technology may be used in smart mobile devices (1003), such as smart watches, smart phones and tablets, virtual and augmented reality headsets, smart earbuds, and other portable and wearable technology. This again allows for location technology without requiring a GPS transceiver. This location data may also be used in activity location tracking technologies, such as exercise applications. This location data may also be used in augmented reality applications and to assist in automated or piloted operation of sidewalk delivery robots, drones and the like.

[156] This localization technology also has application in any situation where GPS alone is not sufficiently accurate, such as cities or areas with low-quality or inconsistent GPS coverage, or applications unsuitable for the operational requirements of a GPS transmitter, such as devices with small form factors and/or limited battery life. This localization technology also has application in any situation where geofencing is desired, such as to prevent operation of devices inside of, or outside of, a geographically defined area.

[157] The locational information may be particularly useful in municipal areas with a large number of tall buildings, which can impede or distort wireless signals and even satellite signals. Additionally, the power drain of long-range transceivers, such as GPS, can be significant, whereas the power drain of a small localized beacon is relatively small. To save battery life, the location system described herein may be used to temporarily replace or supplemental other location services, such as but not necessarily limited to, GPS. This locational system may also be used to provide a secondary or supplemental locational service in situations where limitation in operating system designs inhibit or prevent the use of GPS or other location services.

[158] By way of example and not limitation, the device (201) may comprise circuitry and/or program logic implementing a message/content delivery method suitable for delivering messages or content to nearby pedestrians (1001) or vehicles (1002). In this exemplary embodiment, the mere fact that a mobile device (1003) carried by a pedestrian (1001) or motorist, or a vehicular telematics system (1004) of a vehicle (1002) is able to detect the presence of the beacon (1011) is indicative that the pedestrian (1001) or vehicle (1002) is physically proximate to the beacon (1011).

[159] The location of the pedestrian (1001) or vehicle (1002) can then be determined in real time with precision using any number of techniques. When the mobile device (1003) or telematics system (1004) is close enough to detect wireless signals from the beacon (1011), whether or not mobile device (1003) or telematics system (1004) actually joins the network, the unique identifier (1015) for nearly beacon(s) (1011) can be received and looked up in the database (1013) to find the associated geographical location (1017) for the mobile device (1003) or telematics system (1004). This location can then be used for messaging or content delivery (e.g., via a mobile application (1005) or within the vehicular telematics system (1004)).

[160] The action taken may vary from embodiment and embodiment and will depend on the particular design and business goals of the implementation. For example, the user device (whether a mobile device (1003), telematics system (1004), or some other type of user device) may display for the user (1001) a map of the city highlighting nearby attractions, businesses, or amenities that are open, and/or provide walking or driving directions as the case may be, or may indicate the location of nearby rideshare scooters or other small personal vehicles. In another embodiment, the location may be used to deliver spot marketing, such as coupons or promotions for nearby businesses or events. In a still further embodiment, hazard information may be presented, such as weather alerts, flood warnings, street closures, or reports of emergencies or emergent situations such as recent nearby crime or other dangerous situations with directions to nearby shelter, an alternate path, or other information.

[161] By way of further example, another device (201) in the network may be equipped with a microphone programmed to detect gunshots or a vehicular accidents. If one is detected, the devices (201) may further share that information within the network, including the location of the device (201) which detected the incident. That information may then be shared with the user device (1003) to provide a location for the incident in question and allow the user (1001) to avoid the impacted area or seek shelter.

[162] A number of marketing applications are possible. By way of example, an outdoor advertising screen (e.g., an LED display) could be attached to the light pole, and when a mobile device (1003) is detected as approaching, turned on to display a promotional message, such as ad placement for nearby businesses. Alternatively, if the user (1001) has a mobile device (1003) with software (1005) enabled to receive and display such messages, the mobile device (1003) could detect the nearby beacon (1011) and provide the marketing content via an alert the mobile device (1003), including commercial incentives, such as a coupon or discount code.

[163] The devices and methods described herein may also or alternatively be used in conjunction with vehicular location and traffic management systems. In such an embodiment, a vehicle (1002) is equipped with a wireless transceiver (1019) which communicates with one or more beacons (1011) in a municipal deployment. These communications may then be analyzed for various purposes, including but not necessarily limited to routing, location, driver assistance, and autonomous piloting. This could be done, for example, by including a radio transceiver (1019) in the vehicle and using techniques such as analysis of the signal strength, and/or change in signal strength as the vehicle (1002) moves, to determine the vehicle’s (1002) location, heading, speed, and other characteristics. Other technologies may also be used, such as phased array antennas (1019).

[164] The analysis could take place at the vehicle (1002), at the beacon (1011), or at a remote location, but is preferably performed at the vehicle (1002). This is because although the vehicle (1002) could connect to a private network comprised of the plurality of beacons (1011), this is not necessary. As described elsewhere herein, in the ordinary course of operating a wireless network, the beacons (1011) send out frequent status or presence signals, which the transceivers (1019) can detect. The characteristics of these waves can then be analyzed to determine positional and/or locomotive characteristics of the vehicle (1002) without authenticating or connected to a network.

[165] Again, because the beacons (101 1) are attached to a light pole (105) with a fixed geographic location (1017) that can be known, the vehicle’s computer (1004) can be loaded with a database (1013) of node identifiers (1015) and geographic locations (1017). By comparing the known location (1017) of a given beacon (101 1) (e.g., by looking up a unique identifier (1015) associated with the beacon (1011) in a database (1013)), the mere fact that the vehicle ( 1002) is within range to receive transmissions from a given beacon (101 1) can pinpoint a vehicle’s (1002) location to a relatively small geographic footprint. Further analysis of signal characteristics can then refine that determination to greater accuracy, and potentially further determine characteristics such as speed and heading. By using multiple beacons (101 1), accuracy can be further improved.

[166] By way of example and not limitation, suppose a vehicle is traveling down a municipal street with lights outfitted with the luminaire control systems described herein. The vehicle is positioned next to a first node Nl, has just passed a second node N2, and is approaching a third node N3. The signal strength of node Nl will usually be strongest, absent unusual interference, and the signal strength of N2 will be weaker than that of Nl and will grow weaker over time as the vehicle moves further away from the light pole containing N2. Conversely, as the vehicle approaches N3, the signal strength will get stronger. By comparing these various signal strengths, and examining how they change over time, even over relatively small increments, direction, position, and speed can be estimated or inferred.

[167] Although the exemplary embodiments described herein are in the context of a control system for operating a luminaire in a municipal setting, the control system, power supply, and other elements described herein are suitable for use in other applications, in which the control system may implement different or additional functions.

[168] The systems and methods described herein may make use of an enclosure to contain various components, such as, but not necessarily limited to, power supplies and power converts, wireless transmitters, beacons, endpoint devices, and Intemet-of-Things devices. These components may include some or all of the functions described herein with respect to the luminaire control device. As described elsewhere herein, such enclosures may be installed on a municipal infrastructure pole between the light head and the end of the pole arm, and the municipal power supply may be accessed and stepped-down to an appropriate voltage for use by lower-voltage components.

[169] In an embodiment, such an enclosure is a modular enclosure comprising central core enclosure and one or more“bolt-on” modular elements that can be added to the central core enclosure to expand the capacity and functionality of the enclosure as needed. An exemplary embodiment of one such enclosure is depicted in FIGs. 14-17. In the depicted embodiment, a modular enclosure (1400) provides an expandable and configurable moisture-proof or moisture-resistant container having suitable heat dissipation properties to store and operate small electronic equipment in various climates and environments.

[170] In the depicted embodiment, the enclosure (1400) comprises a main body portion (1402) and an extension (1404) rigidly attached thereto. The extension (1404) may be formed as part of the main body (1402) or may be permanently attached to the main body using known techniques. The enclosure ( 1400) may be made from any material suitable for use in the desired environment, taking into consideration environmental factors such as heat, humidity, precipitation, wind, and taking into account operational needs, such as the need to maintain moisture levels and internal temperatures suitable for the operating small electronic equipment and managing the heat generated by such devices. [171] The depicted body portion (1402) is generally in the configuration of a rectangular prism, having various ridges or protrusions disposed at regular intervals on the exterior surfaces. However, in alternative embodiments, different shapes or configurations may be used, depending on the needs of the embodiment. For example, the shape and angle of the light arm to which the enclosure will be attached, the number of type of devices to be stored within the enclosure, and aesthetic considerations may influence the overall shape. The depicted protrusions may provide various environmental functions, such as improved water shedding, inhibiting ice build-up, and provide increased surface area for improved temperature management. In alternative embodiments, the protrusions may be shaped or spaced differently depending on the particular needs of the embodiment and/or anticipated deployment location, or different or additional structures may be used to manage these and other environmental and operational considerations.

[172] The depicted extension (1404) is a generally cylindrical element sized and shaped for mounting a municipal light head upon the extension (1404), effectively having the same basic shape and dimensions as the distal end of the light-arm on which the light head would ordinarily be mounted. The depicted extension (1404) also has a hollow interior volume (1406), which provide a pathway through which wires can be run from the interior of the enclosure (1400) to a light head mounted on the extension (1404). These wires may carry electrical power and/or may be communication or control wires. These aspects are further described elsewhere herein.

[173] As can be seen in the depicted embodiments, the enclosure (1400) may comprise one or more mounting points (1408) for attaching additional modular elements to the enclosure (1400) at various points on the enclosure exterior. These modular elements can expand the storage capacity and functionality as needed for each individual light pole. This reduces cost and waste by allowing each pole to be configured with the particular modules needed. These modular elements are further described elsewhere herein. The mounting points (1408) may comprise screw holes for using hardware to attach the modular components, or may be used to attach mounting rails or other structures known in the art for temporarily but rigidly attach rugged elements together so as to prevent or inhibit unwanted disengagement due to wind, seismic activity, tampering, a vehicular collision with the pole, natural wear, and so forth.

[174] As can be seen in FIGs. 15-16, the back of the enclosure body (1402) is a generally open side that can be covered in part by attaching a corresponding back plate (1410). The depicted back plate (1410), when attached to the back of the enclosure body (1402) covers or obscures most of the open back, and provides a moisture-proof or moisture-resistant seal. The depicted back plate (1410) comprises a cutout (1420) generally in the configuration of a halfarena. This shape, when combined with the opening (1422) of the receiver (1416) provides a circular opening (1422) on the back. The depicted circular opening (1422) is sized and shaped to accept the distal end of a municipal light arm for purposes of mounting the enclosure (1400) on the arm. Thus, the assembled enclosure (1400) can be installed by removing the light head from the light arm, installing the enclosure (1400) on the light arm at the receiver (1416), and then installing the light head on the extension (1404).

[175] As can be seen in the depicted embodiment, the back plate (1410) comprises one or more openings (1412). As further described elsewhere herein, these openings (1412) may be used to pass wires connected to the components stored within the interior (1414) of the enclosure (1400) to components stored outside of the enclosure (1400), such as components stored in the module elements, or on the light (e.g., a bar light or tube light, or a secondary light for illuminating a sidewalk, as described elsewhere herein). This may be done by simply passing a wire through the opening (1412) and sealing the opening for water resistance, or by creating an electrical-mechanical interface (e.g., a“plug”) that fills the opening, allowing connecting wires to simple be plugged in. Again, the interface should be considered to be moisture-proof or moisture-resistant and to provide a firm connection to inhibit moisture penetration or unintended disconnection. Two openings are shown, but this is not limiting and a given embodiment could have one, or two or more openings, depending on the needs of the particular embodiment. It is also possible to have no such openings in embodiments where all components are stored internally, but it is anticipated that most embodiments would utilize the external modular and thus have openings (1412) to provide wire paths. Although the depicted openings (1412) are shown on the back plate (1410), in an alternative, openings could be disposed elsewhere on the enclosure (1400), such as on the top or bottom surfaces.

[176] In the depicted embodiment of FIG. 16, an enclosure (1400) is shown in cut-away, illustrating the interior components. As can be seen in the depicted embodiment, the interior (1414) of the enclosure (1400) is generally hollow, and includes a receiver (1416) sized and shaped to accept a municipal light arm. The depicted receiver (1416) comprises a pair of opposing arcuate members which are essentially mirror images of one another and which, together, partially circumstance a hollow, generally cylindrical interior (1418). This results in the dorsal side of the receiver (1416) having an open channel, which can be used to pass wiring from the light arm to the light head. Thus, electronic equipment can be installed within the enclosure (1414) but outside of the receiver (1416), and municipal power lines in the light arm can be accessed via the channel to power components stored within the interior (1414) (e.g., a power supply, transmitter, control boards, etc.).

[177] The depicted receiver (1416) is disposed such that its major axis is generally perpendicular to the back plate (1410) when installed, and generally centered horizontally on the back plate (1410) when installed. Likewise, the depicted extension (1404) is disposed such that its major axis is generally perpendicular to the front surface of the enclosure body (1402). In the depicted embodiment, the central axes of the extension (1404) and the receiver (1416) are generally collinear, making the receiver (1416) and the extension (1404) coaxial. This facilitates interlineation of the enclosure (1400) between a light head and a light arm. Additionally, the extension (1404) and receiver (1416) are in fluid communication with each other, providing a conduit from the interior of the light arm through the enclosure and into the light head when the enclosure (1400) is installed between a light head and light arm.

[178] The interior (1404) of the enclosure (1400) may be sized and shaped to accept various components, which are described elsewhere herein, and may include members for providing mount points for such elements, such as tabs, mounting rains, screw holes, and so forth. Generally, the interior (1414) of the enclosure body (1402) is used for power supply to convert the municipal voltages from the light arm to voltages usable by smaller electronics, and the converted voltages are passed out of the enclosure (1400) to the modular elements via wires passing through the openings (1412). However, this is not necessarily limiting, and there may be embodiments in which the enclosure (1400) itself houses components such as wireless transmitters and endpoint devices.

[179] FIG. 17 depicts an embodiment of the modular enclosure (1400) with a plurality of modular components (1424), (1426), and (1428) attached to it. The enclosure (1400) is depicted installed on a light arm (10533). In the depicted embodiment of FIG. 17, a cobra light arm (10533) is shown with a flexible tube light (10501) attached thereto via a flexible mounting system (10001), as described in more detail elsewhere herein. The depicted enclosure (1400) is installed on the cobra arm (10533) by inserting the distal end of the cobra arm (10533) into the receiver (1416).

[180] A first modular component (1424) is shown disposed on a first lateral side of the depicted enclosure (1400), a second modular component (1428) is shown disposed on a second lateral side of the depicted enclosure (1400), and a third modular component (1426) is disposed on a top surface of the modular enclosure (1400). These modular components (1424), (1426), and (1428) are mounted to the enclosure (1400) using the mounting points (1408). [181] The depicted modular components (1424), (1426), and (1428) are generally in the configuration of enclosed rectangular prisms, each having one arcuate surface. The depicted modular components (1424), (1426), and (1428) are elongated members, and sized and shaped to accommodate the components intended to be stored within each. The general aesthetic styling matches that of the enclosure (1400), providing improved performance in various environments and an aesthetically pleasing uniform appearance.

[182] Each of the depicted modular components (1424), (1426), and (1428) has a removable back plate comprising one or more openings (1430). The back plate of each is attachable in a moisture-resistant or moisture-proof manner and can be removed to access the interior to install, repair, and change the interior electronic components. As with the back plate (1410) of the enclosure (1400) itself, these openings may be used to pass wiring through the exterior to connect to the interior components, which may be done using a socket/plug that provides an electrical-mechanical interface.

[183] For example, a first depicted opening (1430) is shown without any moisture-proofing for illustrative or testing purposes. When the device is deployed for production use in the elements, the opening (1430) would be weatherproofed, similar to a second depicted opening (1432). The second depicted opening (1432) provides an electrical-mechanical interface in the nature of a socket or receptacle for plugging a cable into the back of the modular component (1426). Inside the modular component (1426), wires connect this interface to the interior components in a manner known in the art.

[ 184] This can be further seen with respect to a third opening ( 1434), which has a cable (1436) plugged into it at a first end. The opposing end of the cable (1436) is plugged into another interface in the back plate (1410) of the enclosure (1400). This cable (1436) thus provides electrical communication between components stored inside of the enclosure (1400) and components stored inside the modular component (1424). The cables will typically comprise a plurality of separate wires contained within an outer sheathe, which may provide power transmission and/or communication exchange. The particular configuration and purpose of the cable (1436) may vary from embodiment to embodiment.

[185] As shown in the depicted embodiment, modular component (1424) has another opening (1438) shown with a cable (1440) plugged into it, and the opposing end of that cable (1440) is not plugged into the enclosure (1400), but rather is connected to the tube light (10501) mounted on the cobra arm (10533). In this configuration, the tube light (10501) may be controlled using components stored within the enclosure (1400) and/or of the modular component (1424) via the cables (1440) and (1436). That is, municipal power received via a municipal line in the cobra arm (10533) may be accessed within the interior (1414) of the enclosure body (1402) via the channel in the receiver (1416). That power may then be stepped down to a lower voltage usable by a control board and transmitter, and then the lower voltage passed to the modular component (1424) via the appropriate cable (1436), or the power may be passed out without conversion at the municipal voltage level.

[186] In the modular component (1424), if stepped-down power is received, it may be used to power a control board for providing commands to and operating the tube light (10501), and/or it may be used to power a wireless transmitter which can receive such commands and provide them to the control board to operate the tube light (10501). These commands/instructions may be passed to the tube light (10501) via the connected cable (1440). Additionally, or alternatively, power at the appropriate level may also be provided to the tube light (10501) via the cable (1440).

[187] The particular location of the various elements - power supply, control board, transmitted, etc.,— may vary from embodiment to embodiment depending on the particular needs of the deployment and which components require power. If an external component such as tube light (10501), for example, requires power at a different voltage than the small electronic components, the municipal power may be passed out of the enclosure (1400) unmodified, and then stepped down by a power supply with the modular component (1424) to power internal small electronics, but then also passed back out to the light tube (10501) unmodified to power it.

[188] It will be understood that the various systems and methods described elsewhere in this disclosure are applicable to the depicted structures of FIG. 17. By way of example, and not limitation, the transmission and receipt of network instructions and statuses may be carried out using wireless transmitters located within these components. Similarly, the functions of the luminaire control device described herein may also be included in the enclosure (1400) and/or one or more attached modular components (1424), (1426), (1428). This may be done in addition to, or alternatively to, the inclusion of these functions or features within the luminaire control device. Likewise, one or more modular components (1424), (1426), and (1428) may implement any of the functions described herein, such as the endpoint devices, sensors, and nodes. These functions may be included in a single enclosure (1400) and/or modular component (1424), or may be distributed amongst two or more.

[189] The modular components (1424), (1426), (1428) each may have additionally components, depending on the particular function or needs of the enclosure. For example, the depicted modular components (1424) and (1428) have attached antennas, which may be used to send/receive wide-area radio transmissions, such as via a cellular or wireless data network, may provide for short-range transmissions as part of a mesh network, and/or may provide municipal Wi-Fi services or other services described elsewhere, such as, without limitation, point marketing, vehicular navigation assistance, and IoT devices such as sensors and cameras.

[190] Also, described herein is a flexible and controllable municipal light tube and a corresponding universal architectural mounting system for installing such lighting upon a municipal utility pole. The mounting system includes generally a flexible, inverted track form that receives a light, and has a retention system for affixing a light to the mount, and an attaching system for affixing the mount to a light pole. The mounting system is a bracket having the form of an inverted track to receive a lighting tube. The bracket may have a base and plurality of flanges used to either hold the lighting tube or attach to a pole. The base and flanges form a U-like shape and are made from a flexible material allowing the bracket to be shaped to conform to a pole to which it attaches. A foam layer may be inserted between the bracket and tube to inhibit unintended disconnection.

[191] A first embodiment is shown in FIGs. 18, 19, 20, and 21. In the first embodiment, the mounting system has a base, a left flange, and a mutually parallel and spaced apart right flange, the three combining into an inverted U-like shape. The base may have a width generally about, or at least, twice that of a flange. The flanges may cabin a LED strip within the mount and prevent lateral illumination from it. The base, the left flange, and the right flange are opaque and permit some play between the strip and mounting system. To restrict that play, a pinch clip with a first tip and a spaced apart second tip that both impart a compressive force upon the flanges may be used. The pinch clip may have a slender elongated form. The compressive force arises from deflection of the pinch clip and imparts a gentle squeeze upon the two flanges, thus retaining the strip within the mounting system and along the arm. The base may be at least twice as wide as a flange, mounting clips, a plurality of pinch clips spaced regularly, flanges sized to strip depth, and an alternate adhesive connection.

[192] FIG. 18 shows a perspective view of a portion of a light (10101) outwardly and coaxial with a cobra arm (10533) and a first embodiment of the mounting system installing upon an end of the cobra arm (10533) and receiving the light (10101). The cobra arm (10533) attaches to a light pole (10103) erected upon a sidewalk or other location for illumination by light (10101). A strip of light emitting diode lighting (10507) connects to the cobra arm (10533) along at least a portion of its length utilizing the depicted embodiment. [193] FIG. 19 has an enlarged perspective view of two lights (10101) upon the cobra arms (10533). The cobra arms (10533) have a generally elongated shape with an arcuate form. The two cobra arms (10533) extend to their maximum separation at the lights (10101) upon (10005) their ends and then gradually curve to a common point upon the pole (10103). Each cobra arm (10533) has a strip of LED (10507) connected to it upon its length. Each cobra arm (10533) has two spaced apart ends, a free end to which a light (10101) connects, and an opposite fixed end with which the cobra arm (10533) connects to the pole (10103).

[194] FIG. 20 shows a perspective view of the first embodiment deployed upon a pair of cobra arms (10533). This embodiment has a generally elongated form and retains a strip of LED lighting (10507) along its length on each of the cobra arms (10533). The depicted mounting system permits uninterrupted electrical operation of the LED lighting strips (10507). This (10001) provides a continuous smooth connection of the strips (10507) along the arcuate shape of the cobra arms (10533).

[195] More particularly shown in FIG. 21, the depicted mounting system (10001) has an elongated, arcuate, form with two ends, similar to a track. The depicted mounting system receives a strip of LED (10507) placed within it and then the depicted mounting system allows for clear transmission of light from the strip (10507). The depicted mounting system has an opaque outer surface, shown as at (10001a), which abuts the cobra arm (10533) itself during installation and later usage. The outer surface preferably provides continuous contact of the depicted mounting system to a cobra arm (10533). Though FIG. 21 shows one mounting system, a typical cobra arm installation upon a pole calls for two. FIG. 21 also has a detailed partial view shown of an end. The depicted mounting system (10001) has a generally inverted truncated U-like shape. The depicted mounting system functions as a track that receives an LED strip (10507). The depicted mounting system has a base (10001b), here shown as flat, a left flange (10003) and a mutually parallel and spaced apart right flange (10004). The left flange (10003) and the right flange (10004) both extend in the same direction. The base has a width generally at least twice that of either flange. The left flange (10003) and the right flange (10004) cabin an LED strip (10507) placed within the depicted mounting system and prevent lateral illumination from the strip (10507). The base, the left flange (10003), and the right flange (10004) generally have an opaque construction. Formed in the U-like shape, the left flange (10003), the right flange (10004), and the base permit some play between a strip (10507) and the depicted mounting system (10001) during installation. The depicted mounting system includes a pinch clip (10002) of a generally slender, elongated form with two ends. The ends include a first tip (10005) and a spaced apart second tip (10006). The first tip (10005) abuts the left flange (10003) and the second tip (10006) abuts the right flange (10004) and both tips impart a compressive force upon their respective flanges. The compressive force arises from deflection of the pinch clip (10002) and imparts a gentle squeeze upon the two flanges, thus retaining the strip ( 10507) within the mounting system during its usage. The depicted mounting system (10001) includes a plurality of pinch clips (10002) spaced along its length to counteract the weight of the strip (10507) as needed. In an alternate embodiment, the depicted mounting system (10001) secures the strip (10507) within itself using an all-weather adhesive.

[196] FIGs. 22, 23, 24, and 25 depict an alternative embodiment of a universal mounting system, and a flexible light tube. The depicted light tube (10501) is generally in a configuration of an oblate half-cylinder, comprising a base element (10509) and a diffuser (10513). The depicted base element (10509) is a generally flat, elongated element in the configuration of a rectangular prism extending the length of the tube (10501) along its major axis, and having a hollow channel (10511) therethrough having a generally rectangular cross-section sized and shaped to accept a light strip (10507). Attached to a top side of the base element (10509) is an elongated diffuser generally in the configuration of an arch defining an elongated hollow channel (10515) between the diffuser (10513) and base element (10509) extending the length of the tube (10501).

[197] The tube (10501) and its elements are generally constructed from flexible, weatherproof or weather resistant materials, such as rubbers and polymers. The base element (10509) may be fully or generally opaque, and may be a different material and/or opacity from the diffuser (10513). The layer of material between the light channel (10511) and the diffuser channel (10515) is generally opaque, causing light emitted by a light strip (10507) disposed in the light channel (10511) to transmit into the diffuser channel (10515), and from there to transmit through the diffuser (10513) walls to the exterior of the tube (10501).

[198] The depicted light strip (10507) is a double-LED light strip, having two runs of corresponding side-by-side LED lights disposed in a series along the length of the light strip (10507). When assembled, the light strip (10507) is disposed in the light channel (10511) and generally runs the length of the tube (10501), causing LEDs to be disposed along most or all of the length of the tube (10501), and possibly longer. Electrical power and other communications may be provided to the light strip (10507) via a wired connection (10510) or one or more leads (10510) extending therefrom, which are then connected to other components for powering and/or controlling the lights.

[ 199] The shape and contour of the diffuser ( 10513) in any given embodiment may be adapted to cause a particular type, degree, or amount of light diffusion from the light strip (10507) disposed in the light channel (10511). In the depicted embodiment, an arcuate configuration is shown to cause light dispersion in about a 180-degree arc from the plane of the base element (10509), but other shapes and opacities may be used in other embodiments depending upon the particular design or aesthetic purposes of the embodiment.

[200] Also depicted in FIG. 22 is a mounting bracket (10505) sized and shaped for attaching a corresponding light tube (10501). The depicted mounting bracket (10505) is generally an elongated, flexible base element having at least one flange (10517) extending generally perpendicularly therefrom. In the depicted embodiment, a plurality of flanges (10517) are shown along the length of the base. Each of the depicted flanges (10519) has an aperture therethrough for using an attaching element (10531) to affix the bracket (10505) to a light pole (10533).

[201] It is generally anticipated that flanges (10517) will be disposed in opposing, generally parallel pairs extending in the same direction from opposing sides of the bracket (10505) body. Further, the apertures (10519) for any given pair of flanges are generally coordinated to define a rectangular plane or prism, such that an attaching element (10531) passed perpendicularly through one aperture (10519) of a flange (10517) may proceed directly across the body of the bracket (10505) to pass through the aperture (10519) of the corresponding, opposing flange (10517).

[202] The depicted base is generally manufactured from a sheet of stainless steel or another flexible, durable metal that may be bent or formed to correspond to the contour of a municipal utility pole arm. The length of the bracket (10505) is generally about the same length as the length of the light tube (10501) to be attached to it, but in an embodiment, may be longer or shorter as needed. The light tube (10501) may be affixed to the bracket (10505) via a firm, weatherproof or weather resistant adhesive.

[203] As seen in FIG. 23, the depicted light tube (10501) is attached on a side of the bracket (10505) opposing the direction in which the flanges (10517) extend. As explained with respect to FIG. 25, this prevents the flanges from inhibiting light dispersion and facilitates attachment to a light arm (10533).

[204] In an embodiment, a retention element (10503) may be disposed between the bracket (10505) and light tube (10501). In such an embodiment, the retention element (10503) may be affixed to the bracket (10505) via a durable, weatherproof or weather resistant adhesive, and the light tube (10501) may then be attached to the retention element (10503), also via a durable, weatherproof or weather resistant adhesive. In the depicted embodiment, the retention element (10503) is a durable, weatherproof and/or weather resistant foam. It is believed that by interposing a foam retention element (10503) between the bracket (10505) and light tube (10501), unintended detachment is inhibited. FIG. 23 depicts the embodiment of FIG. 22 in an assembled configuration.

[205] To further inhibit unintended detachment, which could cause a light tube (10501) to fall on pedestrians or vehicles, an endcap may be installed. FIG. 24 depicts an embodiment utilizing such an endcap (10521). The depicted endcap (10522) is sized and shaped to be affixed to an end of the assembled mounting bracket (10505)/light tube (10501) combination. The illustrative embodiment of FIG. 24 omits the retention element (10503), but it will be clear to a person of ordinary skill in the art that the endcap (10521) may be sized and shaped to accommodate an embodiment including the retention element (10503).

[206] The depicted endcap (10521) is made from a hardened, durable material, and generally an inflexible or rigid material, such as a hard plastic. The depicted endcap includes a cover element (10522) that surrounds the diffuser (10513) at an end of the assembled bracket (10505)/tube (10501), and holds it snugly within the cover (10522) to inhibit slippage or detachment. The endcap (10521) may then be attached to the bracket (10505) using hardware, such as a pair of screws (10527) passed through openers or grooves in flanges (10525) of the endcap (10521). This provides a more sure method of affixation and, if the adhesive were to fail, inhibits the light tube (10501) from fully detaching from the bracket (10505) and potentially injuring people or damaging property.

[207] The depicted endcap (10521) further comprises a wiring channel (10523) passing axially through the endcap (10521). This channel (10523) allows the wires or connections of the light strip (10517) to be passed through the endcap (10521) and connected to power and control components. This channel may include a gasket or other weatherproofing elements to inhibit penetration by moisture and/or debris.

[208] FIG. 25 depicts the assembled embodiment affixed to the arm (10533) of a municipal utility pole. In the depicted embodiment, the assembled device is affixed by use of an attaching element (10531) which passes through the apertures (10519) in corresponding flanges (10517) and is then attached to the arm (10533). This attaching element (10531) may be anything from a simple industrial tape to metal strip, similar in nature to a ducting clamp. In the depicted embodiment, the bracket (10505) is attached at each of a set of corresponding flanges (10517) to provide a sure connection and inhibit the assembled device from slipping down the arm (10533). The attaching element (10531) may be supplemented by an adhesive or high-friction pad to further inhibit slippage.

[209] As can be seen in FIG. 25, in this embodiment, the flanges are disposed towards the light arm (10533) and the light tube (10501) is disposed on the opposing side of the bracket (10505), projecting light outward and generally downward from the light arm (10533) toward the land below. The connecting lines (10510) for power and control may then be run to a device or apparatus (10550) containing appropriate power supply and control components.

[210] Because the bracket (10505) and tube (10501) are both flexible, the assembled device may be manufactured to the desired length of the light arm (10533) and bent or formed on-site during installation to correspond to the shape or contour of the arm (10533). Likewise, the attaching element (10531) may be a flexible and adjustable element, allowing a connection regardless of the shape of the cross-section of the light arm (10533), or even variations in the size or shape of the light arm (10533) along its length.

[211] While the invention has been disclosed in conjunction with a description of certain embodiments, including those that are currently believed to be the preferred embodiments, the detailed description is intended to be illustrative and should not be understood to limit the scope of the present disclosure. As would be understood by one of ordinary skill in the art, embodiments other than those described in detail herein are encompassed by the present invention. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention.

[212] Throughout this disclosure, terms such as“generally,”“about,” and“approximately” may be used, such as, but not necessarily limited to, with respect to geometric terms, including shapes, sizes, dimensions, angles, and distances. One of ordinary skill in the art will understand that, in the context of this disclosure, these terms are used to describe a recognizable attempt to conform a device or component to the qualified term. By way of example and not limitation, components described as being“generally coplanar” will be recognized by one of ordinary skill in the art to not be actually coplanar in a strict geometric sense because a“plane” is a purely geometric construct that does not actually exist and no component is truly“planer,” nor are two components ever truly coplanar. Variations from geometric descriptions are unavoidable due to, among other things, manufacturing tolerances resulting in shape variations, defects, imperfections, non-uniform thermal expansion, natural wear, and other deformations. Further, there exists for every object a level of magnification at which geometric descriptors no longer apply due to the nature of matter. One of ordinary skill in the art will understand how to apply relative terms such as“generally,”“about,” and“approximately” to describe a range of variations from the literal geometric meaning of the qualified term in view of these and other considerations. Additionally, the use of the conjunctive and disjunctive should not necessarily be construed as limiting, and the conjunctive may include the disjunctive, and vice versa.

[213] It will further be understood that any of the ranges, values, properties, or characteristics given for any single component of the present disclosure can be used interchangeably with any ranges, values, properties, or characteristics given for any of the other components of the disclosure, where compatible, to form an embodiment having defined values for each of the components, as given herein throughout. Further, ranges provided for a genus or a category can also be applied to species within the genus or members of the category unless otherwise noted.
