[001] This application claims priority to United States provisional patent application serial number 62/182,437, filed June 20, 2015, the content of which is incorporated herein by reference in its entirety.

Technical Field of the Invention

[002] In embodiments, the technical field of the invention pertains to networked mobile electronic devices and systems for supporting such devices.

Background

[003] Digital education in the classroom exists in various forms. Traditionally, a digital education solution would consist of various individual components including servers, computing devices, projectors, printers, and various network connectivity technologies. These solutions are installed and maintained by trained professionals and they require substantial infrastructure in both connectivity and power in order to function. Whereas these systems work well in developed economies, there are challenges with reliability and fitness for use in constrained environments such as, but not limited to, emerging markets in Africa.

[004] In an attempt to simplify the installation and use of digital education in emerging markets within constrained environments, more recent art describes the integration of connectivity and storage of computing devices into rugged and portable enclosures. These systems, while addressing some aspects of the challenges of deploying digital education in constrained environments, still require substantial infrastructure and training in order to be utilized in infrastructure constrained classrooms. Because of the dependence of skilled training and advanced infrastructure, these systems provide only marginal improvement over traditional art.

Detailed Description of Various Embodiments [0047] The systems, devices, and methods of the invention provide improvements in the way that content is delivered to multiple users. The improvements are especially suitable in resource constrained locations and/or regions with harsh environmental conditions.

[0048] In an aspect is a system for supporting a plurality of mobile computing devices comprising: a reversibly sealable enclosure; a wireless charging system disposed within the enclosure and comprising a plurality of wireless charging transmitters configured in a fixed array; a securing scaffold disposed within the enclosure and defining a plurality of identical slots; and a plurality of mobile computing devices configured to be wirelessly charged by the wireless charging system, wherein each slot is configured to receive and mechanically secure one of the plurality of mobile computing device in an optimized charging position relative to one of the wireless charging transmitters.

[0049] The system comprises a reversibly sealable enclosure. In embodiments the enclosure comprises a base and a lid, and the two can be closed to form a reversible seal. By reversibly sealable is meant that the enclosure can be repeatedly opened and closed, such as by a user, and that each time the enclosure is closed, it is sealed. The enclosure may comprise a lock or latch, such that the reversibly sealing refers to locking or latching (or otherwise securing from unintentionally opening) the enclosure shut. Thus, by "seal" is meant to include locking or latching the enclosure. Alternatively or in addition the term "seal" may further include closing the enclosure such that water, dust, or other external contaminants are resisted from entering the enclosure (e.g., the enclosure is sealed to be weather-resistant and/or dust-resistant). A variety of mechanisms can be used to create a weather- and/or dust-resistant seal, such as with rubber gaskets or the like. Latches and other fittings can be used to create a locking seal or a securing seal (that may or may not be weather-resistant and/or dust-resistant). Furthermore, in embodiments, the enclosure may be shock resistant and/or shatter-resistant, such as by forming the enclosure from a hard plastic (shock- and/or shatter-resistant) material (e.g., ABS plastic or the like). In embodiments, the enclosure's seal includes a locking mechanism or is configured to be locked by a separate lock so as to provide security of the contents of the enclosure.

[0050] The enclosure can be any suitable size provided that there is sufficient space for the components disposed therein. In embodiments, the enclosure is within 1-12, or 2-10 ft ³ in volume, or greater than 1, 2, 3, 4, or 5 ft ³ . The dimensions and weight of the enclosure may be of any suitable values, with such values being determined by the number of computing devices, the optional components present in the device, and the materials with which the system is constructed. For example, in embodiments the length, width, and height of the enclosure (lid plus base) are within the range of 0.75-4 ft, or 1-3 ft. In embodiments the enclosure has a greater length and width compared with the height, with the effect of improved stability of the enclosure. For example, the height is in the range 0.75-2 ft while the length and width are independently in the range of 1-4 ft.

[0051] The enclosure can include, in embodiments, a hole in one wall with an air filter and an optional fan disposed therein. The air filter and optional fan allows purified air to enter the enclosure (purified, e.g., of dust and other contaminants). The hole may contain a flap or other cover that helps to direct air into the filter and optional fan. The air filter and fan are present to help dissipate heat that might be generated when the mobile computing devices are charging, particularly where such charging occurs when the enclosure is in a closed configuration.

[0052] In embodiments, the system comprises a plurality of mobile computing devices, the number being in the range 2-60, or 5-50, or 10-40, or 20-40, or 30-40, or greater than or equal to 10, 15, 20, 25, 30, 35, 40, or 50, or the number being 10, 20, 30, or 40 devices. In embodiments, the number of devices is equal to the number of slots present in the scaffold so that each device is paired with a dedicated slot.

[0053] Each mobile computing device is configured to be wirelessly chargeable. Thus, each device comprises a wireless charging receiver. The wireless charging receiver is located within the device such that it is optimally positioned relative to the wireless charging transmitter associated with a slot in the securing scaffold. For example, the wireless charging receiver may be located centrally along the length and width of the device, or may be located off-center as desired. In embodiments, the mobile computing device and the internally disposed wireless charging receiver are configured such that the mobile computing device can be inserted in to a slot in the enclosure in either of two orientations ("up" or "down", which may be distinguished, for example, by the positioning of a power button or port on the device) and still align with the wireless charging transmitter assigned to the slot. For example the wireless charging receiver may be positioned centrally along the width and height of the device. In such an embodiment, the user may insert the device in any orientation that fits the slot and still obtain optimal charging position of the device in the slot. In embodiments the mobile computing device is rectangular so the slot has a greater depth compared with its width, and there are only two configurations that a device could be inserted in the slot (but the slot and devices are configured to allow both configurations to work equally well). In embodiments, the device is square so the device and slots are configured to allow the device to be inserted in any of four orientations and achieve optimal charging position. In other embodiments only one orientation of the device achieves optimal charging position, and the device is labeled to indicate to the used the correct orientation for insertion in the slot.

[0054] Each mobile computing device has an external case and is configured to be weather resistant and dust resistant. Thus, holes or openings in the case (e.g., holes for buttons, ports, or the like) are covered by removable covers, such as by rubberized cover seals. The cover seals may be attached to the case such that they cannot fully detach from the case (reducing the likelihood of losing the covers). Holes or openings may be present for a variety of purposes, including buttons (e.g., a power or volume buttons), data ports (e.g., a USB port or the like), jacks (e.g., earphone or mic jacks), or the like. In embodiments, the external case is shock-resistant such as by being made of a shock-resisting hard plastic material or the like. In embodiments, the external case includes a touch screen on one face (the touch screen being integrated into the device as an I/O component of the device), and the touch screen may be integrated into the case such that a weather-resistant and dust- resistant seal is maintained. The mobile computing devices may comprise a processor, memory, I/O components (e.g., USB port, touch screen, speaker, etc.), communications components (e.g., WiFi component, etc.), or any combination thereof. The mobile computing devices may be the size of tablets or mini-tablets (e.g., screen size of 5-10, or 5, 6, 7, 8, 9, or 10 in diagonal), or may be smaller or larger as desired. The mobile computing device may be a tablet, clamshell computer, notebook computer, netbook computer, convertible computing device, or other variation of a portable computing device with integrated battery.

[0055] Disposed within the enclosure is a securing scaffold. As described herein, the securing scaffold secures the wireless charging system and the mobile computing devices in proper alignment for optimal wireless charging of the devices. The scaffolding comprises and forms a plurality of slots - one slot for each mobile computing device to be supported in the system. The securing scaffold may comprise a variety of structural assemblies and/or molds (some of which are described below and herein), as well as combinations thereof, in order to perform the functions of the securing scaffold. Such functions include forming the slots that receive mobile computing devices, securing and holding the wireless charging transmitters, forming a structural element inside the enclosure to which other structural elements can be attached, forming compartments and securing other components inside the enclosure, and the like.

[0056] In embodiments, each slot in the securing scaffold is independently formed by a one-piece mold, such as a metal or plastic mold. The mold can be configured such that a plurality of molds can be inserted into the enclosure as an array of molds to support the plurality of mobile computing devices. These one-piece molds can be held in place within the enclosure by compression (e.g., sufficient numbers of the molds are present to exert pressure against the walls of the enclosure) or they can be attached to other structural elements of the enclosure such as cross-bars or the like. In embodiments, each slot is independently formed from a two-piece assembly (or alternatively a multi-piece assembly). The two pieces of a two-piece assembly can be identical, mirror-images, or asymmetric The two-piece assembly can be modularly configured such that a first slot formed from a first two-piece assembly can be positioned next to a second slot formed from a second two- piece assembly, and so on (e.g., infinitely stackable slots). In embodiments of asymmetric two-piece assembly, one piece provides a supporting structural (e.g., a metal plate that extends across the enclosure and provides a support structure for a plurality of slots) and the other piece defines each slot (e.g., a plastic mold defining one or more slots). In embodiments, a plurality of slots are formed by the same pieces of a single two-piece assembly such that the slots are not independently formed. In embodiments, each slot is sized and shaped such that a mobile computing device is rigidly held within the slot - i.e., the device is held stable with little or no ability to shift or move laterally once inserted in the slot. In such embodiments the cross-section of the slot is the same or similar shape as the cross-section of the mobile computing device, and is only slightly larger (e.g., 0.2-2 mm in each direction) in order to allow the mobile computing device to be inserted in the slot. The slot comprises four or more walls (e.g., four walls for a completely rectangular cross- section, or more walls for non-rectangular cross-sections) and a base support, and the walls and base ensure proper and rigid positioning of the mobile computing devices. In embodiments the materials that form the slot (whether one-piece, two-piece, or multi- piece) are rigid such that the mobile computing device, when disposed within the slot, is rigidly held in position.

[0057] In embodiments, the slots are configured to rigidly position adjacent mobile computing devices in a substantially parallel configuration. For example, each device is parallel to each adjacent device within a margin of 0-5°, or 1-3°, with the error being due to the minimal/inconsequential amount of lateral movement of the device within the slot (due to the necessity of a small gap between the device and the walls of the slot, as defined herein). The substantially parallel configuration allows maximally efficient use of space in the enclosure as well as maximum efficiency of charging by the wireless charging system.

[0058] A wireless charging system is disposed within the enclosure. The wireless charging system comprises a plurality of wireless charging transmitters (also referred to herein as an array of wireless charging transmitters). In embodiments, one wireless charging transmitter is present for each slot in the securing scaffold. The wireless charging transmitters may be interconnected and collectively connected to a power source via appropriate wiring. Each wireless charging transmitter is positioned and configured to provide wireless charging to a mobile computing device when the device is inserted in a slot in the enclosure.

[0059] The wireless charging system comprises a power source internal to the enclosure or a connector configured to connect to an external power source. For internal power sources, an example is a battery or fuel cell disposed in the enclosure. A battery may be rechargeable and the system may further comprise solar panels (e.g., on or within the lid of the enclosure) or a connection to an external power source (e.g., the electricity grid providing 120 or 240 V AC, or external solar panels) for recharging the battery. In embodiments, the connection to an external power source may provide charging power to an internal power source - e.g., an internal battery is charged by a connection to an external source. Alternatively, connection to an external power source may be the primary source of power supplied directly to the charging transmitters - an external power source includes, for example, the main electricity grid. Where AC and DC sources are mixed (e.g., a main electricity grid connection for recharging an internal battery), appropriate AC/DC converting components are used. Where the system comprises a connection to an external power source, the connection can be male (e.g., a power cord extending from the enclosure) or female (e.g., a power receptacle suitable for connecting to a power cord).

[0060] The wireless charging system may further comprise a power control unit. In embodiments the power control unit independently or collectively controls the activity of each wireless charging transmitter. The power control unit may further comprise a power converter and be configured to supply DC power output (to the charging transmitters) from either AC or DC power input.

[0061] Initiation of the charging process can be automatic - e.g., immediately and constantly occurring whenever power is supplied to the wireless charging system and a mobile computing device is present in a slot (e.g., as detected by a change in the inductance of the charging transmitter, or as detected by a physical switch within the slot to register the presence of a device, etc.), or a sensor can be present to detect the battery level in a mobile computing device, and charging can be initiated as appropriate based on the sensor readings. The charging process involves inductively transferring power from the wireless charging transmitters of the enclosure to the wireless charging receivers of the mobile computing devices. Such inductive power transfer requires specific positioning of the wireless charging transmitters and receivers, which positioning is obtained and maintained rigidly by the slots of the securing scaffold. The efficiency of the inductive charging process is determined by the relative positions of the wireless charging transmitter and receiver, and the slot is configured to ensure a "charging position" of a mobile computing device that optimizes the wireless charging (i.e., obtains minimal charge time and maximal charging speed of the battery in the mobile computing device).

[0062] Each of the wireless charging transmitters is assigned to a slot and is rigidly held in a position relative to the slot by the securing scaffold (whether the scaffold comprises one-piece molds, two-piece assemblies, or alternative means for forming slots). In embodiments, the transmitter is held between separate two-piece assemblies. In embodiments, the transmitters are distributed throughout the securing assembly such that each slot has a secured and rigidly held transmitter in a position suitable for optimized charging by a mobile computing device inserted in the slot (i.e., the device is held in an optimized charging position relative to the location of the transmitter in the scaffold).

[0063] The systems may further comprise a variety of additional components, some of which are described below.

[0064] In embodiments, the system comprises a wireless router disposed within the enclosure. In embodiments, the wireless router is configured to interface with a wireless network transceiver, such as wireless network transceivers in each of the mobile computing devices. The wireless router may be disposed within the enclosure and may be easily accessible (i.e., exposed when the enclosure is opened) or may be hidden by paneling, insulation, or the like. In embodiments, the wireless router is part of a control unit (described in more detail herein). The wireless router can provide short-range communications via a WiFi hotspot, and/or can use any other means of communicating with the mobile computing devices (e.g., Bluetooth, etc.).

[0065] The system further comprises a communications module for communicating with an external network (e.g., the Internet or a WAN or other dedicated network). The communications module may be a component of a control unit (described below) or a component of a server (described below). Description provided herein and pertaining to the communications module is equally applicable whether the communications module is part of a control unit or a server.

[0066] In embodiments, the system comprises a server disposed within the enclosure. The server may comprise a storage module (e.g., memory such as a hard disc or other type of non-volatile memory) and a processor unit, along with programming instructions (machine readable instructions) for carrying out the various methods described herein and desirable of the server. In embodiments the server is configured to store and process digital content such as educational materials and entertainment materials in a variety of digital formats. In embodiments the server comprises machine readable instructions configured to instruct the server to coordinate distribution of content stored on the server and/or obtained via a network to the mobile computing device. Such distribution is typically via a wireless network (e.g. via the wireless router mentioned herein) but may also be via a physical connection if desired. In embodiments, the server is part of a control unit (described in more detail herein). In embodiments the server contains a

communications module suitable for communicating with an external network, although in other embodiments such communications are carried out by the control unit. In

embodiments, the server is a low-power server (e.g., requiring less than 20, 15, 10, 8, or 5 W). In embodiments, the server storage is at least 50, 100, 200, 300, 400, 500, or 1000 GB.

[0067] In embodiments, the system comprises a control unit. The control unit may comprise a variety of components such as a server (as described above), a communications module, a wireless router (as described above), and other components as desired, and any combinations thereof. The communications module is configured for communicating with an external network and is present for a variety of reasons, including: receiving updates in software operating one or more components of the system; receiving digital content; and transmitting information including content generated on/by the control unit and/or content generated on/by the mobile computing devices. In embodiments, the

communications module comprises a SIM (subscriber identification module) interface suitable for receiving a SIM card, and/or alternatives to a SIM (e.g., components suitable for a MNO - mobile network operator). The communications module may be suitable for communicating via a 2G, 3G, 4G, CDMA, EDGE, or other type of network.

[0068] In embodiments, the control unit is disposed within the enclosure, and may be easily accessible or may be positioned so as to be accessible only by technicians (e.g., for maintenance). In embodiments, the control unit comprises a hard case, wherein such case may be shock resistant, dust resistant, weather resistant, or any combination thereof.

[0069] In embodiments, the system comprises an antenna, or a plurality of antennae. The antenna may be a component of the control unit, or maybe a separate component. In embodiments the antenna is a GSM antenna suitable for extending the range of a GSM network. The system may further comprise an antenna for the wireless router (e.g., a WiFi antenna).

[0070] In embodiments, the system comprises a data port. In embodiments the data port is configured to create a physical connection (via an appropriate cable, which may be included in the enclosure) with a mobile computing device. Examples of data ports include USB connectors, lightening dock, and the like. The data port can be disposed within the enclosure or, in some embodiments, can be disposed on an outer surface of the enclosure. In embodiments of an external data port, there may be a removable cover that creates a water resistant and/or dust resistant seal over the port, thereby maintaining the weather resistance and/or dust resistance of the enclosure. The data port may be connected directly to the server, or to the control unit as appropriate. One or a plurality of data ports may be present, such as 2, 3, 4, 5, or more than 5 data ports (in any combination of internal and external ports).

[0071] In embodiments, the system comprises a compartment disposed within the enclosure. The compartment can be, for example, for storage of peripheral devices such as cabling, adapters, antennae, and the like. In embodiments, the compartment is formed by the arrangement and configuration of the securing scaffold.

[0072] The systems herein may include software and/or hardware for logically securing the mobile computing devices. Such logical security can include passwords and disabling features that ensure that the devices do not work when they exceed a predetermined range from the enclosure.

[0073] In embodiments the system supports the mobile computing devices that are disposed within the enclosure. By "support" can be meant, for example, recharging the devices as necessary to maintain an operable power level, configuring the operating system of the devices when necessary to maintain operations, transferring data to the devices (e.g., from a networked content provider, a server, or some other source), or transferring data from the devices (e.g., to a server for long-term storage or analysis), or a combination thereof. In embodiments, support includes uniform content delivery from a server (e.g., the server in the enclosure or an external server communicating through a control unit in the enclosure) to the plurality of mobile computing devices. Thus, "support" includes maintaining the operability of the mobile computing devices - i.e., maintaining their power supply (battery) with sufficient charge to function, maintaining their operating system and application software with suitable updates, installations, and digital content, and the like.

[0074] The systems described herein are intended to be suitable for rugged

environments and resource constrained environments. The use of a wireless charging system is beneficial because power can be delivered to the devices without the need for physical connections (which are prone to attract dirt and may malfunction if dirt is not sufficiently excluded from the connections). The mobile computing devices are rugged and do not contain exposed ports, holes, or other points that may be prone to collecting dirt. The server and/or control unit and/or other sensitive components is/are suitably sealed with a weather- and dust-resistant enclosures. Various embodiments of the present invention concern the synchronization of computer readable content onto a local storage device that can be accessed through a local server by local devices without a need for perpetual connectivity to the Internet.

[0075] In an example method, the systems can be used to uniformly deliver digital content to the mobile computing devices (e.g., in a school classroom setting). For example, data/content can be downloaded by the server (whether a standalone server or as part of the control unit) and distributed via the wireless router to the mobile computing devices. Such data can be downloaded and distributed simultaneously, or the server can pre- download material that is expected to be needed by the devices, and stored locally on the server. Furthermore, the methods can include centralized management, where a single entity (e.g., a website and website operator) determines the content that is to be

distributed to a plurality of systems according to the disclosure - each system receiving the content as needed or by a predetermined schedule via the communications module.

[0076] Various advantages, including those listed below, are provided by various embodiments of the invention.

[0077] In various embodiments, the invention provides methods to connect to WAN (Wide Area Networks) or other connection to centralized servers. These servers can be used to provide either real-time or cached content to the end user or optionally for system updates. These connections can be 3G/LTE/GSM, WiFi, Microwave, TV White Space or any other technology providing such a data connection, optionally multiple redundant links may be utilized. Optionally one way data connections, such as, but not limited to, Satellite technologies, LHF, VHF, UHF or other broadcast technologies can be utilized to update the cached data in the system.

[0078] In embodiments, the systems require only a single power cord and a single power button. Other embodiments are also provided that require few inputs from the user. The invention therefor enables a simplified setup and usage scenario for environments without trained ICT resources. In embodiments, the entire system is integrated to function from the one power input and the single power switch. [0079] By using an integrated wireless charging technology combined with a mechanically aligned device slot, each computing device can be automatically made to charge by inserting into a storage slot. The use of wireless charging prevents the occurrence of mechanical failures that result from improper mechanical charging connections such us USB and barrel connectors. Further, the non-contact charging solutions will operate in environments with high levels of airborne particulates that might otherwise effect exposed electrical connections.

[0080] By fully integrating an entire technology stack inclusive of wireless access points, network routing, computing, and content storage, the solution is able to provide a turnkey environment for hosting interactive digital learning programs without the need for perpetual connectivity to the Internet. Furthermore, by integrating an Internet

connectivity device (e.g., the control unit herein), the invention is able to access multiple forms of connectivity from broadband to 3G as well as other WAN/Backhaul technologies. Because, however, connectivity is not required for the invention to function, the availability of connectivity can be used to remotely administer the invention, synchronize content, and provided limited browsing capabilities.

[0081] The systems can be configured for automatic content synchronization, which reduces the cost and delays of accessing new content across all of the devices within range of the WiFi access point.

[0082] In embodiments, the systems are weather-resistant, secure, and comprise an integrated charging enclosure. By providing a single enclosure that is designed to protect the devices from the elements, provide a mechanically aligned charging slot, and provide an ability to physically lock and secure the devices, the invention is able to protect its various components in all physical conditions. Furthermore, the systems allow remote administration and monitoring. By providing a fully integrated remote administration portal, the invention is able to deliver both remote monitoring and remote administration of the invention regardless of the physical location of the kit.

[0083] The methods and devices described herein include a memory coupled to the processor. Herein, the memory is a computer-readable non-transitory storage medium or media, which may include one or more semiconductor-based or other integrated circuits (ICs) (such, as for example, field-programmable gate arrays (FPGAs) or application-specific ICs (ASICs)), hard disk drives (HDDs), hybrid hard drives (HHDs), optical discs, optical disc drives (ODDs), magneto-optical discs, magneto-optical drives, floppy diskettes, floppy disk drives (FDDs), magnetic tapes, solid-state drives (SSDs), RAM-drives, SECURE DIGITAL cards or drives, any other suitable computer-readable non-transitory storage media, or any suitable combination of two or more of these, where appropriate. A computer-readable non-transitory storage medium may be volatile, non-volatile, or a combination of volatile and non-volatile, where appropriate.

[0084] Various embodiments of the invention are described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown in figures. Indeed, the inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to provide further illustrative non-limiting examples. Arrowheads in the figures are provided merely as examples of directions for the flow of data but are not exhaustive and are not meant to be limiting - i.e., data may flow (where appropriate) in directions that are not shown by arrowheads in the figures. Similar numbers in different figures are meant to refer to similar components.

[0085] Figure 1 illustrates the sub-enclosure (two-piece assembly) providing a slot for mechanically and rigidly aligning device 100 for wireless charging. As shown, a two-piece assembly comprises a first piece 371 and a second piece 372, which pieces align and interface or interlock to provide a physical alignment of a wireless charging transmitter 360 to place the transmitter at an equidistant point to both the horizontal and vertical alignment of device 100 and oriented correctly with the wireless power receiver unit located within device 100. In an alternative embodiment not shown, the charging receiver unit is not required to be equidistant from the device edges. When two assemblies 371 and

372 are interlocked, they provide a physical space (slot) sized to the dimensions of the device 100 that ensures minimal movement and optimal alignment of the wireless charging transmitter 360 to the wireless charging receiver (not shown) in the device 100 enabling a high efficiency of transmitted power.

[0086] Figure 2 illustrates an alternative embodiment to the assembly that forms a slot for receiving a mobile computing device. A slot is formed by the combination of first piece

373 and second piece 374. Wireless charging transmitter 360 fits into second piece 374 and is aligned with a charging receiver of a computing device when the device is inserted into the slot. Each piece 373 and 374 may be independently prepared from metal or plastic and can be attached to adjacent pieces thereby forming a scaffold throughout an enclosure.

[0087] Figure 3 illustrates certain logical components of an embodiment of the invention. The system is controlled by a smart network router 310 that provides for the ability to receive connectivity via either Ethernet 230 from a broadband provider or 3G 220 from a wireless carrier. The router 310 provides for external connectivity via a WiFi connection 210 that is extended over a longer range through a WiFi extender 200. The router 310 providers wireless access to a dedicated server 320 that hosts a HTTP server for providing access to various local content 330 through an HTTP browser on mobile computing device 100. The embodiment includes a power controller 350 that transforms 220/240V mains electricity (not shown) into a regulated DC charging source for the wireless charging transmitters 360 and for the battery 340 supplying the router 310.

Alternatively another input source (not shown) may be used and may interface with power control unit 350. Each device 100 includes a wireless charging receiver 110 that receives wireless power when in proximity to and aligned with the wireless charging transmitter 360.

[0088] Figure 4 illustrates the system interactions between mobile computing device 100 and various sources of content. As such, the system control unit 380 manages access to content from both a local content store (server) 320 and from the broader Internet 90. Administration of the controller 380 is accomplished through a network connection to the administration portal 80 that also provides a source for synchronizing content onto the local storage 320. The administration portal 80 also provides for mechanisms to allow or restrict access to Internet content through a series of rules that are maintained by the control unit 380. A client mobile computing device 100 connects to the control unit 380 and then is provided with various access to local and public content.

[0089] Figure 5 illustrates enclosure 400, an embodiment of enclosure as described herein. Enclosure 400 comprises lid 410 and base 420, which are reversibly sealable. The seal may involve a locking mechanism (not shown) or may involve a weather-resistant and dust-resistant seal such as rubberized seal 430. Also integrated into base 420 is air filter 460, which comprises a filter for impurities and a fan (not shown). Within the enclosure, a securing scaffold (not labeled) creates a plurality of slots 440. The securing scaffold may be covered by a foam or otherwise cushioning cover, provided that such cover maintains the slots and their ability to receive mobile computing devices. Also disposed within enclosure 400 is control unit 380, which may comprise a number of individual units such as a server, wireless router, and the like as described herein. Also within enclosure 400 is

compartment 450, which is configured to store a variety of peripheral devices and accessories. An antenna (not shown) may be present and connected to control unit 380, and may be conveniently disposed within or attached to the inside surface of lid 410, or another convenient location as desired.

The integrated education system was contained in a weather-resistant enclosure that provides for environmental protection, ventilation if desired, and with security of the contained components. The system is controlled by a control unit that contains a wireless router, 3G modem, computer server, and computer storage. The control unit is enabled/disabled with a single switch which controls the entire system. Within the invention are multiple mobile computing devices that are able to connect to the system control unit using the IEEE 802.11 protocol (WiFi). The system control unit provides a Hyper Text Transfer Protocol (HTTP) server whereby the devices can access computer content that is delivered using the HTTP protocol. Optionally, other transfer protocols are available for use in the system to transfer information. The invention provides for an extended range of the IEEE 802.11 protocol through the optional use of an integrated WiFi extender. The mobile computing devices are stored within individual slots constructed into the enclosure that provide for mechanical alignment of the wireless charging system. The enclosure includes optional additional storage capacity in the form of a compartment for the storage of headphone devices to provide private listening to audible content on the devices.
