Abstract: An apparatus includes a shelf having a front edge, a solar cell circuit disposed at the front edge, a display screen, and a controller operatively coupled to the solar cell circuit and the display screen. The controller monitors the period of a waveform of a charging voltage of a storage capacitor of the solar cell circuit, displays an image on the display screen in response to a change in the waveform timing. A system includes a plurality of shelves each having a front edge, a solar cell circuit disposed at the front edge of each of the plurality of shelves, and a controller operatively coupled to the solar cell circuits. The controller monitors the frequency at which a power transfer of each solar cell circuit occurs, and signals a device in response to a change in the frequency at which the power transfer occurs.

Abstract: Systems and methods to co-locate RFID readers with in-band sensor networks, such as LoRa sensor networks, are disclosed herein. An example arrangement is a co-located device that includes a dual-mode transceiver configured to communicate with targets operating in a first protocol (e.g., RFID) and other targets operating in a second protocol (e.g., LoRa). The example arrangement includes a dual-mode controller that operates the dual-mode transceiver to communicate via the first protocol during a first time period while disabling communication via the second protocol and to communicate via the second protocol in a second time period while disabling communication via the first protocol.

Abstract: A method and apparatus for locating a moving target in a venue and for capturing a sequenced timeline of target directed images is described. Target sensing stations having a wide-angle video camera, such as a 180° video camera, are positioned within the venue. Each sensing station includes a sensing unit, such as radio frequency identification (RFID) transceiver unit, that determines a location and/or direction of travel of the target. The sensing station correlates the RFID transceiver information with the wide-angle video camera to specifically filter and process a video stream from the camera, producing target directed image snapshots from the stream that are assembled at a centralized controller into the sequenced timeline images that may be used in monitoring target movement and to establish location chain for prevention of unauthorized movement.
