The device signatures comprise the inventory of devices in the insured's home and are used to create an electronic record of the devices that assists him in filing a claim with an insurer that is quick and easy after a theft or total loss. Using the device signatures provided by home telematics devices' sensing an itemization technology, fraud detection is also possible. Additionally, analytics software predicts possible failure by analyzing the device signatures. ## Claims ### Claim 1 An apparatus comprising one or more processors and one or more memories storing instructions that, with the one or more processors, configure the apparatus to: generate, based at least in part on scanning digital streams associated with a plurality of operating devices within a physical structure, a plurality of operating feature vectors representative of respective device signatures for each operating device of the plurality of operating devices, wherein generating the plurality of operating feature vectors based at least in part on scanning the digital streams comprises forming digital samples based at least in part on sliding sampling windows on the digital streams; retrieve, from an operating device inventory associated with the physical structure, a plurality of stored feature vectors representative of stored respective device signatures for inventoried operating devices within the physical structure; and responsive to determining that one or more stored feature vectors are absent from the plurality of operating feature vectors, prepare an electronic insurance claim for one or more operating devices associated with the one or more stored feature vectors. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the digital streams comprise the digital samples representative of one or more of (a) transient voltage noise, (b) continuous, line-synchronous voltage noise, (c) continuous, high-frequency voltage noise, (d) pressure waves in the plumbing infrastructure, or (e) acoustic responses of a gas regulator. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the digital samples are generated by sampling analog signals received from operating devices. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein each inventoried operating device is associated with a classification. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein an operating device is one of an appliance, a fixture, a light bulb, a fan, a motor, an HVAC system, a forced air heater, a stove, a dryer, an electric heater, a compressor, a compact fluorescent lamp, a motor appliance, a gas-operated device, a mechanical device, a switched load, a television set, a DV player, a charging unit, a computer, or a mobile device. ### Claim 6 A computer-implemented method, comprising: generating, by one or more processors and based at least in part on scanning digital streams associated with a plurality of operating devices within a physical structure, a plurality of operating feature vectors representative of respective device signatures for each operating device of the plurality of operating devices, wherein generating the plurality of operating feature vectors based at least in part on scanning the digital streams comprises forming digital samples based at least in part on sliding sampling windows on the digital streams; retrieving, by the one or more processors and from an operating device inventory associated with the physical structure, a plurality of stored feature vectors representative of stored respective device signatures for inventoried operating devices within the physical structure; and responsive to determining that one or more stored feature vectors are absent from the plurality of operating feature vectors, preparing, by the one or more processors, an electronic insurance claim for one or more operating devices associated with the one or more stored feature vectors. ### Claim 7 (depends on 6) The method of claim 6, wherein the digital streams comprise the digital samples representative of one or more of (a) transient voltage noise, (b) continuous, line-synchronous voltage noise, (c) continuous, high-frequency voltage noise, (d) pressure waves in the plumbing infrastructure, or (e) acoustic responses of a gas regulator. ### Claim 8 (depends on 7) The method of claim 7, wherein the digital samples are generated by sampling analog signals received from operating devices. ### Claim 9 (depends on 6) The method of claim 6, wherein each inventoried operating device is associated with a classification. ### Claim 10 (depends on 6) The method of claim 6, wherein an operating device is one of an appliance, a fixture, a light bulb, a fan, a motor, an HVAC system, a forced air heater, a stove, a dryer, an electric heater, a compressor, a compact fluorescent lamp, a motor appliance, a gas-operated device, a mechanical device, a switched load, a television set, a DV player, a charging unit, a computer, or a mobile device. ### Claim 11 A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of an apparatus, configure the apparatus to: generate, based at least in part on scanning digital streams associated with a plurality of operating devices within a physical structure, a plurality of operating feature vectors representative of respective device signatures for each operating device of the plurality of operating devices, wherein generating the plurality of operating feature vectors based at least in part on scanning the digital streams comprises forming digital samples based at least in part on sliding sampling windows on the digital streams; retrieve, from an operating device inventory associated with the physical structure, a plurality of stored feature vectors representative of stored respective device signatures for inventoried operating devices within the physical structure; and responsive to determining that one or more stored feature vectors are absent from the plurality of operating feature vectors, prepare an electronic insurance claim for one or more operating devices associated with the one or more stored feature vectors. ### Claim 12 (depends on 11) The non-transitory computer-readable storage medium of claim 11, wherein the digital streams comprise the digital samples representative of one or more of (a) transient voltage noise, (b) continuous, line-synchronous voltage noise, (c) continuous, high-frequency voltage noise, (d) pressure waves in the plumbing infrastructure, or (e) acoustic responses of a gas regulator. ### Claim 13 (depends on 12) The non-transitory computer-readable storage medium of claim 12, wherein the digital samples are generated by sampling analog signals received from operating devices. ### Claim 14 (depends on 11) The non-transitory computer-readable storage medium of claim 11, wherein each inventoried operating device is associated with a classification. ### Claim 15 (depends on 11) The non-transitory computer-readable storage medium of claim 11, wherein an operating device is one of an appliance, a fixture, a light bulb, a fan, a motor, an HVAC system, a forced air heater, a stove, a dryer, an electric heater, a compressor, a compact fluorescent lamp, a motor appliance, a gas-operated device, a mechanical device, a switched load, a television set, a DV player, a charging unit, a computer, or a mobile device.
