  • Publication number: 20240310566
    Abstract: An electronic device may have a waveguide, an input coupler that couples light into the waveguide, and an optical coupler that couples the light out of the waveguide. A medium may be layered onto the waveguide. The input coupler may include a first surface relief grating (SRG) and the optical coupler may include a second SRG in the medium. The first SRG may be a non-binary staircase SRG having ridges with multiple steps. The second SRG may be a binary SRG having troughs that extend to the height of the lowest steps of the first SRG. A reflective layer may fill the first SRG. Forming the input coupler using a staircase SRG may serve to maximize the in-coupling efficiency of the input coupler, thereby maximizing the efficiency with which the light is provided to an eye box.

  • Patent number: 11113920
    Abstract: A banknote stacking and separating apparatus includes a frame, and a guide plate and a pressing plate that are disposed on the frame. The frame is provided with an entrance-and-exit for a banknote. One end of the guide plate adjacent to the entrance-and-exit is pivotally connected to the frame, and the guide plate is operative to rotate around an axis of a pivoting shaft and is configured to guide a moving direction of the banknote when the banknote is being collected. The pressing plate is configured to support the collected banknotes and press the banknotes towards the guide plate while the banknotes are being separated. One end of the guide plate far away from the entrance-and-exit is provided with a force-releasing surface configured to support the guide plate when the pressing plate presses the banknotes towards the guide plate.

  • Patent number: 10941017
    Abstract: Disclosed are a cash box and a banknote processing device using the same. The cash box includes: a guiding plate, configured to guide a banknote to enter a banknote storage chamber; a pickup roller, configured to output the banknote; and a sensor, configured to detect a position of the guiding plate and a position of the pickup roller. When the guiding plate is in a banknote feeding position or the pickup roller is in a banknote pickup position, the sensor outputs a first signal. When the guiding plate deviates from the banknote feeding position and the pickup roller deviates from the banknote pickup position, the sensor outputs a second signal, wherein the first signal is different from the second signal.
