  • Patent number: 12020873
    Abstract: A sensing keyswitch including a key body, a key-sensing switch and an enabling switch is provided. The key body includes a key top, and a key driver and an enabler which can move with the key top in the same keystroke cycle. The key-sensing switch electrically connected to a key circuit is in a disabled mode to save power and cannot sense the change of the sensing intensity caused by the movement of the driver. The enabling switch is electrically connected to an enabling circuit, wherein when the enabling switch is triggered by the enabler, the enabling switch outputs an enabling signal through the enabling circuit for enabling the key-sensing switch to enter an enabled mode, so that the key-sensing switch can sense the change of the sensing intensity caused by the movement of the key driver to trigger a key signal.

  • Patent number: 12009933
    Abstract: The described technology is generally directed towards adaptively selecting a repetition level in wireless communications, based on events to improve coverage range via the repetition level while not unnecessarily reducing throughput. One such event can include a current signal-to-noise-ratio, e.g., as reported in a channel quality indicator report from a user equipment. Another such event can comprise a number of consecutive hybrid automatic repeat request acknowledgments or negative acknowledgments (HARQ ACKS/NACKS), in which consecutive ACKs tend to indicate good signal quality, while consecutive NACKs tend to indicate poor signal quality. A combination of channel quality indicator-based adaptive repetition level and HARQ ACK/NACK-based adaptive repetition level can be employed.

  • Patent number: 11990295
    Abstract: An illuminated keyswitch includes a keycap, a pair of frames adapted to support the keycap in an up-down movement, the pair of frames disposed corresponding to each other and substantially rotatably coupled to each other to define an inner space under the keycap, a pair of elastic members connecting the pair of frames to be located at two opposite sides of the inner space, respectively, and an illumination light source disposed between the pair of elastic members in the inner space and adapted to provide an illumination light. During the up-down movement of the keycap, a vertical projection of the pair of frames surrounds the inner space without interfering therewith, so the illumination light passes the inner space to illuminate the keycap.

  • Patent number: 11978598
    Abstract: A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

  • Patent number: 11951638
    Abstract: A method for determining a standard depth value of a marker includes obtaining a maximum depth value of the marker. A reference depth value of the marker is obtained based on a depth image of the marker, and a Z-axis coordinate value of the marker is obtained based on a color image of the marker. When the reference depth value and the Z-axis coordinate value are both less than the maximum depth value, and a difference between the reference depth value and the Z-axis coordinate value is not greater than 0, the depth reference value is set as the standard depth value of the marker; and when the difference is greater than 0, the Z-axis coordinate value is set as the standard depth value of the marker.

  • Patent number: 11923159
    Abstract: A keyswitch structure includes a keycap support mechanism and a keycap that is supported by the keycap support mechanism in a vertical direction. The keycap support mechanism includes a base and two supports. The base has two sliding slots. Each sliding slot has an opening in a horizontal direction and an obstruction block at the opening. The horizontal direction is perpendicular to the vertical direction. Each support has a sliding portion and a linkage portion. The sliding portions slide parallel to the horizontal direction in the sliding slots correspondingly. The obstruction block prevents the corresponding sliding portion from disengaging from the corresponding sliding slot. The two linkage portions push against each other in line contact, so that the two supports are mutually driven through the two linkage portions.
