Abstract: An adaptive noise cancelling system utilizing a plurality of multi-axis accelerometers and a plurality of microphones, wherein the plurality of multi-axis accelerometers and the plurality microphones may be used in combination to pick up vibrations on a chassis of a vehicle. The accelerometers may be positioned at point near the suspension knuckles or joints of the vehicle, and the microphones may be positioned near the headrest and sun visor of the vehicle. The adaptive noise cancelling system may use an adaptive algorithm to derive one or more filter weights that model a transfer function between the vibrations on the chassis of the vehicle to an acoustic pressure at the plurality of microphones location.

Abstract: An analog multi-gigabit receiver and/or transceiver can be implemented for the reception and demodulation of multi-gigabits quadrature phase shift keying (QPSK) modulated using a CMOS (complementary metal-oxide semiconductor) process. Further, an analog multi-gigabit receiver and/or transceiver can be implemented for the reception and demodulation of multi-gigabits binary phase shift keying (BPSK), minimum shift keying (MSK), and/or amplitude shift keying (ASK) signal modulated in CMOS processes.

Abstract: A digital image stabilization method that integrates a digital stabilization device and a digital video encoder is disclosed. The digital stabilization device comprises a determining module for determining background regions, a comparison module for calculating motion vectors, and an adjustment module for adjusting jerky image motion in frames. When there are frame jiggles, the motion vector between an I frame and a P frame is used for motion estimation to get a first motion vector and also define a background region of the P frame. Next, a second motion vector of a B frame is calculated according to the background region to adjust jerky motion of the P frame and the B frame for stabilization. The next P frame then uses the background region of the preceding P frame as its background region.

Abstract: A camera using a programmable aperture is disclosed in which a programmable lens is disposed between a lens assembly and a sensor to properly transmit or block light rays reflected by a photographed object and incident to the lens assembly and then received by the sensor so as to obtain records of the incident light rays at different positions on the lens assembly. Moreover, complete light field data of the photographed object can be restored to facilitate subsequent image processing at any focal length.

Abstract: A method and apparatus for processing DVD video data and sub-picture data is accomplished by storing a line of DVD video data and at least a partially decoded portion of DVD sub-picture data. The partially decoded DVD sub-picture data is still in an encoded format, which may be two bits per pixel, but line information has been decoded from the DVD subpicture data stream. Once stored, the DVD video data is retrieved from the memory and scaled to produce scaled video data. Similarly, the partially decoded sub-picture data is retrieved from memory, further decoded, and scaled to produce scaled sub-picture data. The scaled video data is blended with the scaled sub-picture data to produce a video output.

Abstract: An integrated graphics processor provides a type of universal programmable synchronization signal generation that provides a plurality of different formats of display synchronization signals. In one embodiment, the integrated graphics processor includes a graphic and video blender that mixes image layers together prior to output for display. The graphics and video blender receives graphics and video data obtained from a frame buffer that may contain multiple formats of data, such as data in different color spaces, such as in a YUV color space (i.e., as per ITU-R BT709 or ITU-R BT 601), and in RGB color space. The integrated graphics processor also includes an integrated (internal or on-chip) programmable embedded synchronization signal generator operatively coupled to the graphic and video blender, to provide a plurality of different formats of display synchronization signals for blended information based on a type of display device.

Abstract: A vibration damper is described. A vibration damper with a high dampening ability is required for a scanner because of the requirement of the 0.18 &mgr;m size devices. The vibration damper is placed between a machine and a floor. The vibration damper has an I-shaped girder structure and a material filling the space between the floor and I-shaped girder structure. A support element having two layers of latticed armatures is mounted on the I-shaped girder structure. The support element is filled with cement. A layer of vibration absorber is placed on the cement.

Abstract: The lines or stations of a multi-line office telephone system are sequentially examined to detect a hold tone signal of a specified frequency or frequencies on one or more of the lines. The lines are examined for increasingly longer time periods in accordance with the type of energy sensed at each line. If the line is not active or connected in a first brief period, the scanner then proceeds to examine the next line for a hold tone signal. If wide-band energy is not detected on the line in a second, longer period, the examination of the line is terminated and the scan process is continued to the next line. If wide-band energy above a threshold is detected on the line in a third, still longer period, the detected energy is further examined to determine whether this energy includes a valid hold tone signal. If a hold tone signal is detected on a line, the line is scanned again to detect the removal of the hold tone signal therefrom, whereupon a hold status is assigned to the line.
