Abstract: Described is an apparatus to concurrently measure multiple input voltages at a high sampling data rate, such as at least two mega-samples per second. The apparatus may include a plurality of voltage data acquisition components that concurrently sample different input voltages and produce respective voltage data samples. Each of the plurality of voltage data acquisition components may be directly coupled to a field programmable gate array that receives the voltage data samples, packetizes those voltage data samples, and provide the packetized voltage data samples to a system on chip.

Abstract: Described are systems, methods, and apparatus that monitor potential voltage and/or radiated electromagnetic energy at a premises to determine device usage at the premises. The monitored potential voltage and/or radiated electromagnetic energy may be processed to generate voltage signature data and radiated electromagnetic energy signature data, a signature data pair, of an operational device and that signature data pair may be used to identify at least one of a device type, a device, a device element of the device, and/or an operational state of a device.

Abstract: A wearable device comprises a first member, a second member that is configured to move relative to the first member, a sensor disposed on the first member, one or more components disposed on the second member, and an authentication module. The sensor is configured to output a sense signal that is indicative of a distance between the sensor and at least one of the one or more components. When the wearable device is worn by a user, the wearable device may be authenticated. The sense signal indicates when at least a portion of the wearable device is opened and/or removed. The wearable device may be de-authenticated based at least in part on the sense signal indicating that a portion of the wearable device has been opened or removed.
