    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.
