Title: Perceptual subband audio coding using adaptive multitype sparse vector quantization, and signal saturation scaler
Inventor: MANTEGNA JOHN
IPC: G10L19/038
Filed: 1998-10-28
Abstract: A reduced-complexity real-time audio coder/decoder ("codec") using adaptive sparse vector quantization (ASVQ) classifies signal vectors into one of a plurality of different types. The codec provides low bit-rate compression for music and speech, while being applicable to higher bit-rate audio compression. It includes an in-path implementation of psychoacoustic spectral masking, and frequency-domain quantization using ASVQ and audio-compression algorithms. Critically-sampled subband filter banks maintain time-domain continuity across frame boundaries.  In-path spectral masking usually results in sparse vectors. ASVQ is particularly effective for quantizing sparse signal vectors. In the preferred embodiment, ASVQ classifies signal vectors into six different types (504, 508, 512, 516, 520, and 522). The ASVQ technique applies to general-purpose data quantization as well as to quantization for audio compression. The invention also includes a "soft-clipping" algorithm in the decoder as a post-processing stage, which preserves the waveform shapes of the reconstructed time-domain audio signal in a frame- or block-oriented stateless manner while maintaining continuity across frame or block boundaries.

Patent CA-2531132-A1 (CA)
Inventor: DELARUE GUILLAUME
IPC: G06F3/048
Filed: 2005-12-19
Abstract: The invention is directed to a product life cycle management (PLM) system, comprising a database storing objects, preferably 3D objects, and relations between said objects. The PLM system provides a graphical user interface suitable for displaying to a user a graphical representation of a hierarchy of stored objects. The graphical user interface is adapted, upon selection of a displayed object by a user, to display objects related to the selected object. At a given level in the hierarchy, displayed objects are distributed according to a respective weight. The weight of a displayed object depends on the number of its descendants in the hierarchy, which are displayed in said graphical representation. The invention makes it possible to navigate in a database of a PLM system, storing notably complex modeled objects through interrelated data. Thanks to the principle of the weight dependence discussed above, the solution further allows the user to comprehend its progression through the organized data as well as the relations between objects and this, in an easy and intuitive way.
