摘要： A device, system, and method are presented for detecting motion. The system may include the device and a first transmitter and a second transmitter configured to transmit a first set of wireless signals and a second set of wireless signals, respectively. The device may have a receiver configured to receive the first and second set of wireless signals, and may further include a processing unit that determines a first value and a second value indicative of fading attenuations experienced by the first set of wireless signals and the second set of wireless signals, respectively. The processing unit may further determine whether the first and second values are each consistent with motion of an object in proximity to the device. The processing unit may cause the device to output an indication of presence of the object if both values are consistent with motion of the object in proximity to the device.

摘要： A differential with torque distribution comprises two differentials. The two differentials can be connected in serial with one of the side gear of the first differential driving the housing of the second differential, and one of the side gear of the second differential being connected to the other side gear of the first differential, and vise versa. Hence the torque on the two output shafts of the differential with torque distribution are different. The rotational speeds on the respective two output shafts are independent of the change of torque on the two output shafts.

摘要： Methods and apparatus for diffuse indirect illumination computation using progressive interleaved irradiance sampling. Embodiments may implement a method that amortizes the cost of computing the irradiance integral for diffuse indirect illumination both temporally and spatially in screen space. For each pixel, only one secondary ray is fired. By carefully arranging different secondary ray directions for different pixels according to a sampling sequence, embodiments may filter the noisy estimate so that each pixel receives a relatively uniform coverage of the integrated hemisphere. Some embodiments may use a bilateral filter so that the geometric discontinuities are respected. The sequence may continue to a higher-level of stratification in each frame. This ensures that the rendering is converging to a noise-free result.

摘要： A system and method provide a video description length (VDL) guided constant quality video encoding strategy with bitrate constraint and a video coding system for optimizing encoding bitrate, distortion and complexity of an input video. The method obtains an overall VDL, temporal VDL and spatial VDL of the input video and compares the overall VDL, temporal VDL and spatial VDL of the input video with a reference VDL, temporal VDL and spatial VDL. Based on the comparison, the method adjusts the encoding bitrate, the overall encoding complexity, temporal encoding complexity and spatial encoding complexity of the input video and encodes the input video with the adjusted encoding bitrate, overall encoding complexity, temporal encoding complexity and spatial encoding complexity of the input video.

摘要： A system and method provide a video coding system for optimizing encoding bitrate, distortion and complexity for a video hosting service. The system comprises an encoding module configured to encode multiple videos with a bitrate control strategy, a pair of complexity allocation control parameters and one or more target output video formats specifications, which include target resolution, target bitrate and target quality information. The encoding module obtains encoding bitrate, distortion and complexity performance samples from the encoding. From the encoding bitrate, distortion and complexity performance samples, the encoding module is configured to select optimal encoding bitrate, distortion and complexity performance samples. The encoding computation profile mapping module is configured to obtain multiple computation levels from the optimal encoding bitrate, distortion and complexity performance samples. For each computational level, a pair of optimized complexity allocation control parameters and number of encoding passes are selected.

摘要： A directly coupled-inertia activated mechanism that may be incorporated into a door handle assembly and counteracts inadvertent door opening during a side crash. An inertia lever with certain inertia moment in relation ship to that of the handle is coupled to the handle, such that it rotates in the opposite direction of that of the handle when the handle is being pulled. The inertia lever is capable of canceling totally the inertia force causing the handle to move inadvertently to unlatched position during side impact crash, and stops the handle's unlatching move.
