  • Publication number: 20240333436
    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: 12106964
    Abstract: Provided is a patterning method including following steps. A doped polysilicon layer, a core layer, and an undoped polysilicon layer are sequentially formed on a target layer. The undoped polysilicon layer is patterned to form a polysilicon pattern. A first etching process is performed by using the polysilicon pattern as a mask to remove a portion of the core layer to form a core pattern. A second etching process is performed to remove the polysilicon pattern. An atomic layer deposition (ALD) process is performed to form a spacer material on the core pattern and the doped polysilicon layer. A portion of the spacer material is removed to form a spacer on a sidewall of the core pattern. A portion of the core pattern and an underlying doped polysilicon are removed.

  • Patent number: 12080492
    Abstract: A keyswitch structure includes a lift mechanism and a keycap. Two supports of the lift mechanism support the keycap. There can be a spring structure connecting the two supports for driving the two supports to lift the keycap. The lift mechanism defines a central space extending through the whole lift mechanism in a vertical direction. The spring structure does not enter the central space. The two supports abut against and constrain each other through corresponding structures, to mutually rotate with respect to a rotation axis. The keyswitch structure can include a switch. The switch includes an intermediate support, detachably abutting downward against the lift mechanism or the keycap, and a resilient part, detachably abutting downward against the intermediate support. In the process of pressing the keycap, the intermediate support is separated from the lift mechanism or the keycap, so that the contact force of the switch can be maintained constant.

  • Patent number: 12026019
    Abstract: A portable information handling system having a portable housing with first and second housing portions rotationally coupled by a hinge having an adjustable torque and a sensor disposed at a front corner of a housing portion reduces torque provided by the hinge when in a closed position and an indication is sensed of an end user opening the housing portions. Reducing torque of the hinge that resists housing rotation from the closed position aids an end user in a single handed rotation of the housing to an open position by allowing the weight of the housing to be sufficient to hold the housing in place on a support surface while the housing rotates open.

  • 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.

    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.
