Abstract: A method and apparatus for scalable symmetric data compression and decompression (codec), optimized for real-time processing of high-resolution continuous-tone 2D input, such as video and images. Following a dyadic n-level DWT decomposition of input, the coding of subbands is spatially partitioned to enable strong parallelism that maps into concurrent encoding threads, based on typical artifacts of H-bands on initial levels—large areas of contiguous zeros interspersed with sparse and highly redundant non-zero values. Variable length codewords of both non-zero values and their positions are mapped into a linear bitstream by a combined limited sequential and parallel procedure of at most log2 n iterations, with both lossless and lossy variants enabled. The compressed bitstream of self-delimiting entries is decoded in a symmetric iterative procedure that delivers to decoding threads the non-zero values and position codewords for final image restoration.

Abstract: Disclosed is a self-tapping bone screw, in particular for use as a compression screw or a locking screw for an implant. The bone screw has screw shank, which has a front tip, a cutting region, an intermediate region, and a rear head region. In a transition region including mutually adjoining parts of the cutting region and the intermediate region, the root diameter of the screw shank in the cutting region is greater than the root diameter of the screw shank in the intermediate region, and the outside diameter of the screw shank is constant.

Abstract: A system-on-a-chip (SoC) to process digital audio-video content includes one or more input/output (I/O) interfaces to transmit the digital audio-video content to corresponding I/O devices coupled to the SoC and to receive the digital audio-video content from the corresponding I/O devices. The SoC also includes a cryptographic engine to encrypt the digital audio-video content being transmitted via the I/O interfaces to the corresponding I/O devices and to decrypt the digital audio-video content received via the I/O interfaces from the corresponding I/O devices.

Abstract: The invention relates to a self-tapping bone screw, in particular for use as a compression screw or a locking screw for an implant. The bone screw has screw shank, which has a front tip, a cutting region, an intermediate region and a rear head region. In a transition region comprising mutually adjoining parts of the cutting region and the intermediate region the root diameter of the screw shank in the cutting region is greater than the root diameter of the screw shank in the intermediate region, and the outside diameter of the screw shank is constant.

Abstract: A method and an apparatus for an integrated high definition television controller are described. The integrated high definition digital television controller includes two or more the following functions in a single chip: MPEG2 Transport, Audio and Video Decoders, Video input capture and converter, flexible video scan rate converter, de-interlace processor, display controller and video D/A converters, graphics controller, a unified local bus, N-plane alpha blending, a warping engine, audio digital signal processor, disk drive interface, peripheral bus interfaces, such as PCI bus and local bus interfaces, various I/O peripherals, a bus bridge with a partitioned chip, and a CPU with caches. The integrated controller, in one embodiment, is designed to handle multiple television standards (for example ATSC, ARIB, DVB, AES, SMPTE, ITU) and designed to be deployed in various countries in the world.

Abstract: In an optical disk drive system, an apparatus and method for determining whether data read from a particular field within a particular sector of an optical disk corresponds to a code which specifies that the sector should not be erased. A crystal clock generates a synthesized clock signal. A front-end detector generates a signal synchronized to the synthesized clock signal which represents data read from the field. The signal is then serially shifted by a serial shift register. A comparator compares the shifted signal with the code specifying that the sector should not be erased. If there is a match, a counter is incremented. When the counter reaches or exceeds a pre-determined number, a signal is sent to the optical disk drive system indicating that the sector contains data which should not be erased.
