摘要： 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.

摘要： A workstation captures images of illuminated symbols with a solid-state imager. In an embodiment, the workstation includes a removable camera module in the workstation away from the imager. The camera module captures a secondary image through a window. The captured image of the illuminated symbol and the captured secondary image are independently processed.

摘要： A method and apparatus for a co-located Radio Frequency Identification (RFID) device and ultrasonic device includes an RFID reader loop antenna element oriented parallel to a reflector panel. An ultrasonic emitter is disposed through an aperture in the reflector panel with a horn that extends through the loop element. The horn can serve as a mounting structure for the antenna element. A diameter of the aperture is less than one-quarter wavelength of an operating frequency of the RFID reader loop antenna element. The aperture is located in the reflector panel near a minimum E-field area of the RFID reader loop antenna element.

摘要： A system and method for adaptively illuminating a volume with an illumination system that illuminates a volume of interest using separately controllable near field and far field optimized illumination sources, to maintain an irradiance pattern criteria in the volume, where that criteria may be different for a far field portion of the volume than for a near field portion of the volume.

摘要： A method and apparatus for locating a target in a venue is described. A backend controller activates transmitters in a venue to send burst signals using a double symmetry configuration formed of a plurality of separate transmitter groups. The backend controller activates the transmitters into a second, different configuration for bursting. The resulting location signal information from each configuration is obtained by the backend controller, which then more accurately determines the location of the target in the venue.

摘要： A method of decoding one or more barcodes on a target object with an imaging scanner is described. The imaging scanner comprises an image sensor and a dynamic linear polarizer. The method includes the following: (1) capturing at least one image of the target object through the dynamic linear polarizer with the imaging sensor while the dynamic linear polarizer is set to a different defined polarization during each of N time periods; and (2) processing at least N images of the target object to decode the one or more barcodes on the target object. At least one image that is captured during each of the N time periods. Here, N is an integer that can be three, four, five, six, or other natural numbers.
