  • Publication number: 20180213228
    Abstract: The disclosure proposes a method of fixed-rate line-based embedded video compression and an image processing apparatus using the same method. The method includes at least the following steps. A current encoding frame is received. Pixels in a current encoding frame are grouped on a line-by-line basis, and the grouped pixels are packed into pixel segments. Complexity information of a current pixel segment is calculated according to the pixels therein and neighboring pixels thereof. The current pixel segment is respectively encoded in a differential pulse-coding modulation (DPCM) mode and a truncation mode to generate a DPCM bitstream and a truncated bitstream according to a quantization parameter (QP). Either the DPCM bitstream or the truncated bitstream is selected and outputted according to the complexity information. An amount of bits used by the current pixel segment is feedback to calculate a new QP corresponding to a next pixel segment to be processed.

  • Publication number: 20180058096
    Abstract: A lockset (10) is actuable by pivoting a lever (14) about a longitudinal axis of the lockset (10) by rotating the lever (14) and by pushing or pulling on the lever (14). An actuator linked to the lever extends into a retractor assembly (33) of the lockset and is configured to actuate a retractor (40) to retract a latch bolt (550) in order to enable a corresponding door (22) to be opened. The latch bolt (550) has a blocking surface (560) that is configured to engage an edge of a door strike plate (45) in order to prevent the door (22) from opening. The blocking surface (560) is inclined relative to an axis of the latch bolt (550).

  • Publication number: 20180058117
    Abstract: A handle set (30) comprises an elongated handle (40) that is attached to a corresponding door (32) at two spaced apart locations. A knob (42) is disposed on the door (32) opposite the handle (40). A retractor assembly (80) is interposed between the handle (40) and the knob (42). A handle spindle (62) extends from the handle (40), and a knob spindle (60) extends from the knob (42). The handle and knob spindle overlap one another, and are configured to move axially with one another. However, the knob spindle (60) can be rotated relative to the handle spindle (62). The spindles are configured to interact with the retractor assembly (80) so that pushing the handle (40) or pulling the knob (42) actuates the retractor to withdraw the latch bolt (50), or rotating the knob (42) actuates the retractor to withdraw the latch bolt (50).

  • Publication number: 20170284124
    Abstract: A lockset (10) is actuable by pivoting a lever (14,16) about a longitudinal axis of the lockset (10) by rotating the lever (14,16) and by pivoting the lever (14,16) about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset (10) includes an inside lever (14) and an outside lever (16), each associated with an independent mechanism, each of which can independently actuate the lockset (10). A keyed locking cylinder (250) is disposed axially in the outside lever (16) and pivots with the outside lever (16). The keyed lock cylinder (250) has an opening that pivotably engages an actuator (260). The actuator (260) extends into a retractor assembly (33) of the lockset (10) and is configured to perform an unlocking or locking function when actuated.
