  • Patent number: 10721102
    Abstract: A communication apparatus includes an input terminal, an output terminal, and an interference reduction circuit. The interference reduction circuit is coupled between the input terminal and the output terminal. The interference reduction circuit receives a time-varying data signal. The interference reduction circuit acquires first partial data from the data signal at a first time, and generates a first level-shifted result and a second level-shifted result according to the first partial data. The interference reduction circuit is further configured to acquire second partial data from the data signal at a second time. The interference reduction circuit selects one of the first level-shifted result and the second level-shifted result as a selected result according to the second partial data, and sends the selected result to the output terminal.

  • Patent number: 10637470
    Abstract: An optical keyswitch includes a casing having a movable portion, a shaft movably disposed on the casing, a resilient member accommodated in the casing, and a switch module including a circuit board, an emitter, and a receiver. The emitter emits an optical signal along an optical path to the receiver. When the shaft is at a non-pressed position, the movable portion has a first spatial relation with the optical path, and the receiver receives the optical signal of a first intensity. When the shaft moves, in response to a pressing force, to a pressed position, the shaft compresses the resilient member and pushes the movable portion to move, so the movable portion no longer has the first spatial relation with the optical path, the optical signal received by the receiver has a second intensity different from the first intensity, and the switch module is triggered to generate a triggering signal.

  • Patent number: 10535477
    Abstract: A button switch includes a base having a pillar, a cover disposed on the base, a sleeve, an arm adjacent to the pillar and an elastic member having upward-force-applying, extending-rod, and flexible-rod portions. The sleeve jackets the pillar, passes through the cover, and has first and second ribs. The upward-force-applying portion jackets the pillar and abuts against the sleeve and the base to drive the sleeve to move away from the base. The extending-rod portion extends from the upward-force-applying portion to be connected to the flexible-rod portion located under the first rib. When the sleeve is located at a high position, the second rib biases the arm to deform. When the sleeve is located at a low position, the second rib is misaligned with the arm. The flexible-rod portion crosses the first rib to be released and then collides with the cover to make sound as the sleeve is pressed.
