Figure 1 shows an operational block diagram of a system for automated supervision of consumption and inventory of appliance consumables, according to some embodiments of the invention.

Figures 2A-2D shows non-limiting examples of the system, according to some embodiments of the invention.

Figure 3 shows a flow diagram of a method for automated supervision of consumption and inventory of appliance consumables, according to some embodiments of the invention.

DETAILED DESCRIPTION Non-limiting embodiments of the invention are now described in detail.

In this application, a "utilization cycle" refers to a utilization of an appliance that can be matched with an expected amount of a consumable dispensed during the utilization. Matching may take into account behavior patterns of dispensation of the consumable by a typical or specific user of the appliance.

Reference is now made to Figure 1. In an exemplary embodiment of the invention, a consumables supervision system 100 comprises an appliance monitor 105 and a server 190.

Appliance monitor 105 comprises one or more sensors 120, at least one of which is a triggering sensor 120'; a power source 125; a processor 130; and a reporting module 160. In a preferred embodiment, all components of appliance monitor 105 are disposed in a single unit (box), as shown. Alternatively, one or more components of appliance monitor 105 may be disposed in physically separated locations.

Appliance monitor 105 is disposed in proximity with an appliance 110, either on or next to appliance 110. Appliance monitor 105 is non-integral and electrically unconnected with appliance 110. Placement of appliance monitor 105 requires special skills, and may be performed, for example, by a consumer user of appliance 110. Appliance monitor 105 may be adhered to appliance 110; for example, magnetically, by gluing, with a hook-and-loop fastener (i.e., Velcro), or simply placed on or alongside appliance 110. Sensors 120 may all be disposed together in a single unit. Alternatively, any of sensors 120 may be separately disposed; for example, where optimal positions of each of sensors 120 are in different places in relation to appliance 110.

Sensors 120 each measure one or more physical quantities. The measured physical quantities are affected by one or more operational modes of appliance 110. For example, two sensors of a dishwasher monitor are placed near a dishwasher. One sensor 120, an accelerometer, measures vibrations, which are affected by spraying of water and rotation of the dishwasher's spraying arms. Another sensor 120 measures temperature, which is affected by water temperature.

Operational modes are associated, individually or in their aggregate, with consumption of a consumable 107 used with appliance 110. A method of determining consumption of consumable 107 as a function of operational mode(s) of appliance 110 is further described herein.

Microcontroller 140 can be an equivalent IC, such as an FPGA, for receiving data and performing computational functions. Microcontroller 140 may be accompanied with a non- transitory computer readable medium (CRM) 150, such as RAM and/or flash memory. Microcontroller 140 is programmed with instructions. The programming instructions may be stored in CRM 150 or in microcontroller 140 itself. The programming instructions are configured for microcontroller 140 to receive measurement signals from sensors 120. Preferably, digitization of signals from a sensor is performed internally by microcontroller 140; alternatively an external A/D converter may be used. The instructions are further determine an operational mode of appliance 110 as a function of the received sensor

Microcontroller 140 is a power-saving microcontroller with at least two modes of operation: an awake (active) mode and a lower-power sleep mode. In the sleep mode, microcontroller 140 consumes relatively little power. Such power-saving microcontrollers are well known in the art.

In system 100, microcontroller 140 is normally in the sleep mode. Optionally, non- transitory computer readable medium 150 and/or some of sensors 120 are also normally in a sleep mode. One of sensors 120 is a triggering sensor 120' that is normally awake and continuously monitors a triggering physical quantity. A predefined output of triggering sensor 120'— for example, a measurement exceeding a certain predefined threshold— wakes up microcontroller 140 from the sleep mode. While in awake mode, microcontroller 140 begins digitally recording measurements from some or all of the sensors 120. From the recordings of sensor outputs, microcontroller 140 determines an operational mode of appliance 110.

Continuing with the example of the dishwasher monitor, the accelerometer is a trigger sensor 120'. The accelerometer measures vibrations caused by a spraying cycle of the dishwasher and converts the vibrations into a signal. The signal exceeds a threshold and therefore wakes up microcontroller 140 from the sleep mode. While in awake mode, the microcontroller 140 records measurements from the microphone and the temperature sensor, thereby determining a spray cycle of the dishwasher. Alternatively, to further reduce power consumption, the accelerometer signal exceeding the threshold can cause microcontroller 140 wake up periodically for a short time (e.g., 50 ms every second) to monitor the signals from the accelerometer and temperature sensor, and then return to sleep mode. Upon conclusion of the vibrations induced by the spraying cycle, the accelerometer signal goes below the threshold and microcontroller 140 returns to its normal sleep mode.

In an alternative embodiment, while the accelerometer signal is below the threshold microcontroller 140 can be in the sleep mode and wake up periodically for a short time (e.g., 50 ms every second) to sample the sensors, and then in the awake mode when the accelerometer signal is exceeds the threshold.

Appliance monitor 105 may be pre -configured with information for converting signals from sensors 120 into operational modes of appliance 110. CRM 150 can store an operational mode profile 155 of appliance 110, such as data (e.g., a sequence) of operational modes of appliance 110 and/or expected signals from sensors 120 for onset and continuing operation at operational modes of appliance 110. Microcontroller 140 can be configured (by design or by programming) to dynamically adjust the threshold of triggering sensor 120', according to an expected operational mode of appliance 110. Microcontroller 140 can be configured to employ measurement signals from sensors 120 in order to verify or determine a present operational mode. Microcontroller 140 can be configured to employ feature extraction techniques to determine a present operational mode from a waveform of a sensor output signal. Microcontroller 140 can be configured to employ a multi-sensor fusion function of a plurality of signals from sensors 120 in order to determine a present operational mode.

In some embodiments, microcontroller 140 configuration (e.g., its firmware, or instructions or operational mode profile 155 in CRM 150) is updated automatically from server 190. Updated configurations can include an improved operational mode profile 155, obtained through ongoing training data from a plurality of appliance monitors 105 each monitoring the same model of appliance 110. Additionally, from individualized training data of single instances of appliance 110, to compensate for idiosyncratic behavior of appliance 110.

After determining an operational mode, microcontroller 140 encapsulates operational mode data, which can include a time stamp. Microcontroller may store operational mode data in CRM 150 and/or send operational mode data to reporting module 200.

Reporting module 160 receives operational modes data and sends operational mode reports 260 to one or more computing devices external to appliance monitor 105. Reporting module 160 may send reports 260 of operational modes one-by-one for each an operational mode determined by microcontroller 140, or may send reports 260 in groups of operational modes. Operational mode reports 260 may include identifying metadata such as an ID of appliance 110 and/or user thereof, manufacturer and model of appliance 110, an address of appliance 110, etc.

Reporting module 160 may employ any suitable cellular, wireless, or cabled network protocols to facilitate communication with the computing device. Communication may be physically direct (e.g. using Bluetooth or WiFi), transmitted through a LAN, or routed through a WAN (e.g., using a VPN over the Internet).

In an exemplary embodiment of the invention, a consumables supervision system 100 comprises an appliance monitor 105 and a server 190. Additional processing of operational mode reports 260 is made by server 190. However, it is understood that some or all of this processing may be performed by microcontroller 140 of appliance module 105. Alternatively, or in addition, some computational functions of appliance monitor 105 described herein may be performed by server 190; for example, so as to reduce computations and power consumption by appliance monitor 105. Server 190 is preferably a cloud server 190 accessed through a cloud infrastructure 170, as shown, but can also be a dedicated server or any combination of cloud and dedicated server(s).

For purposes of clarity, the function of server 190 is described through a utilization of one appliance 110. However, it is understood that server 190, or a plurality thereof, may be configured to serve multiple instances of the same model of appliance 110. Additionally, server 190 may service a number of different models and types of appliances (e.g., server 190 may receive operational mode reports from appliance monitors 105 monitoring washing machines, dishwashers, coffee makers, etc.).

Server 190 comprises a communication module 200. Communication module 200 is in communicative connection with a reporting module 160 of appliance monitor 105. Communication module 200 receives operational mode reports 260 from reporting module 160 of appliance monitor 105. Communication between reporting module 160 and communication module 200 can be through any combination of hardware and software protocols known in the art. In some embodiments, the communication is made through Internet of Things (IoT) protocols.

In some embodiments, server 190 comprises an aggregation module 210. Aggregation module 210 receives operational mode reports 260. Aggregation module assembles and stores the operational modes into an operational mode aggregation 215.

In some embodiments, server 190 comprises a utilization cycle database 225. Utilization cycle database 225 stores one or more specifications 227 of one or more utilization cycles of appliance 110. Utilization cycle specification 227 may specify a sequence of operating modes of appliance 110, and their durations, for various kinds of utilization. Utilization cycle specification 227 may specify an operating mode duration as a function of service level of a utilization. For example, for a dishwasher that adjusts the wash duration depending on the quantity of dirty dishes. Utilization cycle specification 227 may specify an amount of consumable 107 expected to be used in the utilization cycle. For example, how much dishwashing detergent powder is recommended or expected by a typical user to dispense of dishwashing soap for a particular quantity of dishes.

Utilization cycle specification 227 may be supplied by a manufacturer of appliance. Alternatively, or in addition, utilization cycle specification 227 may be constructed or improved by training data taken during testing of different utilization types on a number of different appliances 110 of the same model.

In some embodiments, server 190 further comprises a personalization database 250. Personalization database 250 stores one or more personalization specifications 255, which are specific to each instance of an appliance 110 and its users. Personalization specification 255 may comprise data of patterns of consumption of consumable 107 by one or more users of appliance 110. Personalization specification 255 can specify average or expected consumption amounts of consumable 107 used for particular utilization cycles of appliance 110. Personalization specification 255 may store patterns of consumption and ordering of consumables for appliance 110. Personalized information may be improved by testing a number of utilizations by a user of appliance 110 monitored by appliance monitor 105, where the user specifies how much of disposable 107 was used; either for each use or over a period of time as determined, for example, by frequency of placing orders for consumable 107.

In some embodiments, server 190 further comprises a correlation module 220. Correlation module 220 receives operational mode aggregations 215. Correlation module 220 seeks patterns for matching an operational modes aggregation 215 with a utilization cycle specification 227 in utilization cycle database 225. Correlation module determines the expected consumption amount of consumable 107 during the utilization cycle, either taken directly from utilization cycle specification 227 or, if available, from personalization specification 255.

Correlation module 210 may conclude that a particular utilization cycle and consumption has occurred on the basis of matching one or more operational modes in aggregation 215 with operational modes specified in a utilization cycle specification 227.

If a match is not found, correlation module 220 may employ statistical models to determine a utilization cycle and consumption of consumable 107.

Correlation module 210 may conclude that no utilization or consumption was made, if a set of one or more operational modes is not corroborated by other operational modes expected to occur during a utilization cycle.

Server 190 further comprises an inventory module 230. Inventory module 230 maintains and updates an inventory 235 of consumable 107 for said appliance 110. Where a known consumption amount is dispensed in a single operational mode (e.g., in an example described further herein, a setting of a spring of a mousetrap is "consumed" in a single snap of the spring), operational mode reports 260 received by inventory module 230 from communication module 200 are sufficient for updating of inventory 235. Where a utilization cycle must first be determined from operational modes before determining a consumption amount, then correlation module 220 determines consumption amount as a function of one or more aggregations 215 and a utilization cycle specification 227, and, optionally, a personalization specification 255.

After receiving a consumption amount, inventory module 230 adjusts an inventory amount 235 of consumable 107. Inventory amount 235 can include number of unopened units of consumable 107 remaining (e.g., at a facility or home where appliance 110 is located). Inventory amount 235 can include a quantity remaining in packages already opened.

Based on a present inventory amount 235, inventory module 230 may make predictions of when inventory of consumable 107 will reach zero, or a margin of surplus. Inventory module 230 may make employ personalization specification 255 of said appliance 110 to determine a rate of use and/or a desired margin of surplus of consumable.

As a result of a present inventory or a prediction, inventory module 230 determines a kind of service message 270, if any, is needed. A service message 270 can be a notification to a user device 240 that stock of consumable 107 is low or depleted. A service message 270 can be an online order for a specified quantity of consumable 107 to an online store server 800. A service message 270 can be a service request to a server 900 of an appliance service center.

Server 190 further comprises a service module 240. Service module 240 receives requests from inventory module 230 to send service messages 270. Service module 240 prepares the requested service message to the appropriate recipient. Communication module 200 receives and sends service message 270.

If necessary, service module 240 monitors service requests initiated by service message 270. For example, service module 240 may receive a message reporting that an order for consumable 170 was delivered. Service module 240 receives this message and notifies inventory module 230, in order for inventory module 230 to update inventory amount 235 accordingly. Service module 240 may receive manual orders and cancellations from user devices 240. Service module 240 tracks dispositions of the orders and cancellations and upon final disposition closes the order and informs inventory module 230 of the final disposition.

Non-limiting examples are now provided for different appliances in order to further elucidate functions and utility of the invention.

Mousetrap

Reference is now made to FIG 2C, showing a mousetrap monitor 505 monitoring a mousetrap 500 as part of a consumption supervision system 100, according to some embodiments of the invention.

Mousetrap monitor 505 comprises an accelerometer or acoustic sensor 510 and microcontroller 550. Optionally, mousetrap monitor further comprises a motion detector 530 (for example, a passive infrared mammalian body motion sensor). Mousetrap monitor 505 is adhered to mousetrap 500. A mousetrap 500/mousetrap monitor 505 combination may be placed in each of a plurality of locations of a home or other facility.

Sensor 510 generates a signal in response to a snapping shut of a spring-bar 560 of mousetrap 500, caused by a mouse 540 stepping on a trip 520 of mousetrap 500. Signal of accelerometer 510 above a threshold will wake up microcontroller 550 from sleep mode, whereupon processor receives measurements from accelerometer 510 and, optionally, from motion detector 530. Threshold may be set at or below a signal level received from accelerometer 510 from force of a kick reaction to beginning of spring-bar 560 motion. Optionally, microcontroller 550 is programmed to discern between sensor signals from a "soft" snap of spring-loaded bar 560 against mouse 540 (indicating successful trapping of mouse 540) and the "hard" snap of spring-bar 560 against trip 520 (indicating spring-loaded bar 560 was tripped with no mouse 540 trapped). Mousetrap monitor 505 periodically reports to server 190 its status: a) the mousetrap is still open; b) a mouse is trapped in the mousetrap; and c) the mousetrap is closed with no trapped mouse.

A mousetrap 500/mousetrap monitor 505 combination may be placed in each of a plurality of locations of a home or other facility. Statuses of mousetraps 500 may be stored in aggregation module 210. When a pre-determined number of mousetraps 500 have been closed or mice 540 have been trapped, server 190 may send an alert to a computing device 240; for example, to notify a proprietor of the warehouse. Alternatively, or in addition, an alert is sent to a user device 240 some fixed time after a first time a mouse is trapped, in order to minimize decay odors. Alternatively, or in addition, communication module 200 of server 190 notifies an external server 900 of an extermination service that mousetraps 500 should be reset/emptied. Alternatively, or in addition, an order for more mouse bait may be placed with an online store 800.

Paper Dispenser

Reference is now made to FIG 2D, showing a paper-dispenser monitor 605 monitoring a paper dispenser 600 as part of a consumption supervision system 100, according to some embodiments of the invention.

Paper-dispenser monitor 605 is adhered to a moveable part— in FIG 2D, a flap 645— of paper dispenser 600 that is swung or moved in order to open paper dispenser 600 for filling paper dispenser 600 with a new supply of paper 615. A sensor 620 of paper-dispenser monitor 605, such as a magnetometer or accelerometer, is responsive to the motion. When flap 645 is opened, sensor 620 responds to motion of sensor module. Microcontroller 640 is awaken by a threshold signal of sensor 620 and receives a first response from sensor 620. When flap 645 is closed after replacing paper 615, microcontroller 640 receives a second response from sensor 620. Microcontroller 640 determines that paper 615 in paper dispenser 600 was refilled. Preferably, microcontroller 140 determines a refill only if at least a minimum time required to refill dispenser 610 elapses between the first and second responses. For example, the minimum elapsed time can be set somewhere between around two seconds and around five seconds. Optionally, the minimum time can be set by a user. In some embodiments, if a second response is not received within a maximum time after a first response, microcontroller 640 will ignore the first response. Paper dispenser monitor 605 may communicate each refill to server 190, for updating of paper inventory in inventory module. Alternatively, paper dispenser monitor 605 may record how many times paper 615 was refilled and periodically report to server 190.
