  • Publication number: 20160281765
    Abstract: A triple locking hook connector includes a hook, a locking bar, a first spring, a controlling shaft, and a second spring. The hook has an axle hole and a first groove on an end of a hook opening, and has a spacing portion on the other end of the hook opening. An edge of an end of the locking bar has a first bolt. The first spring is to drive a first bolt to keep at the first position and to drive the other end of the locking bar to remain in the spacing portion. The controlling shaft joins the axle hole via a main axle to restrict the first bolt in the first position and to be driven by a second spring to stay at the third position to ensure the locking bar shutting the hook opening.

  • Patent number: 9091295
    Abstract: A safety hook including a hook body, a latch member, a locking portion, and a control member is disclosed. The latch member is capable of rotating about a guide pin and swinging along a guide slot in an arc-shaped path to open or close a hook opening, wherein when the latch member locks and closes the hook opening, the locking portion and the guide pin form a locked chain structure to bear a lateral impact force on the latch member. When the latch member rotates about the guide pin and swings along the guide slot in an arc-shaped path to open or close the hook opening, the control member is capable of driving the locking edge to release the locking portion, so as to open the hook opening by a swinging movement of the latch member.

  • Patent number: 9025673
    Abstract: The disclosure is directed to techniques for evaluating temporal quality of encoded video. Instead of estimating jerkiness based solely on frame rate or motion activity, the number of consecutive dropped frames forms a basic estimation unit. Several human visual system factors, such as sensitivity to temporal quality fluctuation and motion activity, have been taken into account to make the predicted jerkiness more consistent with the actual human visual response. The temporal quality metric can be used to estimate human perceived discomfort that is introduced by temporal discontinuity under various combinations of video shots, motion activity and local quality fluctuations. The techniques can be applied in two modes: (1) bitstream or (2) pixel mode. The quality metric can be used to evaluate temporal quality, or to control encoding or decoding characteristics to enhance temporal quality.

  • Patent number: 8594180
    Abstract: A stereo 3D video frame includes left and right components that are combined to produce a stereo image. For a given amount of distortion, the left and right components may have different impacts on perceptual visual quality of the stereo image due to asymmetry in the distortion response of the human eye. A 3D video encoder adjusts an allocation of coding bits between left and right components of the 3D video based on a frame-level bit budget and a weighting between the left and right components. The video encoder may generate the bit allocation in the rho (?) domain. The weighted bit allocation may be derived based on a quality metric that indicates overall quality produced by the left and right components. The weighted bit allocation compensates for the asymmetric distortion response to reduce overall perceptual distortion in the stereo image and thereby enhance or maintain visual quality.

  • Patent number: 8514199
    Abstract: A capacitive touch panel and capacitance sensing apparatus and method for the same are disclosed. The capacitive touch panel includes a plurality of electrodes, a multiplexer and a capacitance sensing apparatus. The multiplexer selectively connects one of the electrodes to the capacitance sensing apparatus. The capacitance sensing apparatus includes a reference voltage source and a differential comparator, where the reference voltage source generates a modified reference voltage according to noise on stray capacitance of the capacitive touch panel. In a discharging process, the comparator compares an input voltage at the selected electrode and the modified reference voltage. The capacitance change in the electrode can be precisely detected because the noise is eliminated by differential comparison.
