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: Embodiments of the present invention are directed to the field of RFID readers and more specifically to the selective operation of those readers. In an embodiment, the present invention is a system that alternates the operation of an RFID reader between a continuous wave (CW) only state and a read state depending on an absence or a presence of an object of interest within a read-zone of the RFID reader.

Abstract: A radio frequency (RF) identification (RFID) reader is mounted in a venue in proximity to a portal that is openable and closable by a door. The portal reader reads RFID object tags associated with objects that approach the portal. An electrical conductor is associated, and jointly movable, with the door. A portal RFID tag is mounted at the portal. The portal tag is overlain by the electrical conductor in a closed door position and is remote from the electrical conductor in an open door position. The portal tag is readable by the portal reader in either the open or the closed door position. A controller identifies any objects that have passed through the portal based on whether the object tags have been read, as well as whether the portal tag has been read in either the open or the closed door position.
