Title: Joint multiple program error concealment for digital audio broadcasting and other applications
Inventor: SUNDBERG CARL-ERIK WILHELM
IPC: H04H20/00
Filed: 2000-01-14
Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system.  In an illustrative embodiment, a multiple program coder encodes a bitstream associated each of the programs, in accordance with a specified bit allocation. An outer code encoder receives the encoded bitstreams from the multiple program coder, and jointly applies an outer code, e.g., a CRC code, RS code, BCH code or other type of linear block code, to subblocks of a subset of the resulting encoded bitstreams. The outer code is applied such that subblocks of each of the encoded bitstreams in the subset of the encoded bitstreams are associated with a single outer code block. The number of subblocks associated with a given outer code block may be an integer or non-integer number of code blocks. The invention allows a designated number of program subblocks to share a given outer code block, such that outer code error flags can be generated for smaller groups of bits per program than would otherwise be possible. An inner code encoder may be used to apply an inner code, e.g., a convolutional code, turbo code or trellis coded modulation, to the resulting outer code blocks.

Title: Hip joint socket
Inventor: VON CHAMIER WILFRIED
IPC: A61F2/00
Filed: 1998-12-12
Abstract: Hip joint endoprostheses are generally constructed in a modular manner. They are comprised, for example, of a shaft on which a ball head is attached and a hip joint socket constructed of two parts. Said socket is comprised of a socket housing and a socket insert which is a bearing shell for the ball head. Unfavorable material pairings can result between the socket housing and the socket insert especially during assembly of the hip joint socket by mismatching elements which do not fit together. In addition, danger results in that relative movements between the socket insert and the socket housing occur under strain thus leading to wear. As a result, the invention provides that the bearing shell (2) of the hip joint socket (1) is coated with a coating (5), said coating being comprised of a biocompatible metal or a biocompatible metal alloy, in the area of the shell surface (4) with which the shell is inserted into the hip bone.

Inventor: CHEN BRIAN
IPC: G10L25/51
Filed: 1999-03-18
Abstract: A system, method, and product are provided to (1) pre-process one or more primary signals to generate a transformed host-signal and/or a transformed watermark-signal; (2) embed one or more watermarked signals and/or transformed watermark signals into a host signal and/or the transformed host signal, thereby generating a composite signal, (2) optionally enable the composite signal to be transmitted over a communication channel, and (3) optionally extract the watermark signal from the transmitted composite signal. An embedding value may be the closest of all embedding values generated by an embedding generator to a host-signal value that is to be quantized. Embedding values may be based on a trellis-coded pre-determined relationship between embedding values, or on predetermined relationships based on lattice quantization. The method may also include a fourth step of extracting the first watermark-signal value from a composite-signal value to form a reconstructed watermark-signal value. The present invention may also implement adaptive embedding and, in some implementations, super-rate quantization. For example, the invention may be a system that includes an ensemble designator that designates a plurality of adaptive embedding generators, each corresponding to a single watermark-signal value of a co-processed group of one or more watermark-signal components. Also included in this implementation is an adaptive embedding value generator that generates, by each adaptive embedding generator, a plurality of adaptive embedding values.
