Title: Method of block-based texture compression using edge information in a block
Inventor: YEH YUAN-HAU
IPC: G06T9/00
Filed: 2000-11-20
Granted: 2002-02-21
Abstract: The invention relates to the method and system of block-based texture compression using edge information in a block. With the texture compression method in accordance with the invention, the texture is divided into a plurality of blocks with identical size. Firstly, there are created a plurality of pattern templates in advance and each block is divided into two groups in accordance with these templates. Subsequently, the two basic colors of each group are determined and at the same time the two derivative colors of each group deduced from the two basic colors are determined. Each pixel color in each group is chosen from the two basic colors and two derivative colors. At last, the group data is transformed to bit stream with compressed texture format. In a practical example, there are 16 types of edge patterns of blocks defined. At the same time there is a pattern column in the compressed bit stream, which is used to represent block pattern. In another practical example, the sequence of four basic colors in each block can be used to determine the block pattern and such method can omit the pattern column in the bit stream. Decompression method is the reverse operation of the compression method.

Title: Apparatus, method and computer readable storage for interpolating frequency components in signal
Inventor: SATO YASUSHI
IPC: G10L21/0388
Filed: 2001-06-26
Granted: 2002-09-21
Abstract: To provide a frequency interpolation apparatus and method for restoring an audio signal having information compressed at high ratio while preserving high quality of sound. An input digital signal that has a frequency interpolated is converted into a spectral signal representing a spectral distribution of this time series signal by an analyzer. A spectral analysis section decides, as an interpolation band, a deletion band containing no spectrum among bands obtained by dividing this spectral distribution in equal multiple parts. A frequency interpolation processing section estimates an envelope of a digital signal and adds spectra of the spectral distribution within the interpolation band decided by the spectral analysis section by scaling them in accordance with a function of the envelope. A past spectrum for use with the scaling and addition is read from a spectral storage section. A synthesizer restores the spectral signal after addition into the time series signal. Thereby, the audio signal compressed at high ratio by thinning the frequency components can be regenerated while preserving the high quality.

Granted: 2003-05-01
Abstract: A cell such as a lithium ion cell consists of an anode and a cathode comprising respective lithium ion insertion materials, separated by an electrolyte. A practical cell may be made by stacking a plurality of anode plates and cathode plates alternately, and interleaving a continuous layer of polymer electrolyte or separator material between successive anode and cathode plates so it forms a zigzag.

This procedure enables cells to be made with thin electrolyte layers, for example less than 30 mum thick, and hence of low internal resistance.
