Patent CA-2360266-A1 (CA)
Inventor: KEMENCZY ZOLTAN
IPC: H04B7/005
Filed: 2001-10-26
Abstract: An automatic gain control (AGC) and DC estimation and correction technique for wireless communication devices is disclosed. An AGC signal, which controls a gain applied to a received signal by a gain stage to generate a scaled signal, is assigned one of a relatively small number of values in accordance with the amplitude of the scaled signal. An estimate of a DC offset in the scaled signal corresponding to each value of the AGC signal is stored in a memory. A DC estimation arrangement then reads the stored estimate associated with the particular value of the AGC signal from the memory and generates a current DC estimate based thereon. The current estimate is then used to correct the scaled signal for DC offset and to update the stored estimate.

Patent CA-2369176-A1 (CA)
Inventor: CHANG GENE
IPC: A47B65/00
Filed: 2002-01-23
Abstract: The present invention is a free-standing assembly of identical or similar modules with vertical panels that can support all kinds of reading and writing materials including books, binders, magazines, and files, in an upright manner. The multiple panels in an assembly can keep a set of the materials uprightly while users freely withdraw from or insert some copies into the seta The space between panels is adjustable to fit various thickness of the reading and writing materials between the panels. The total length of the assembly can be adjusted by changing the number of modules in the assembly. The modules are solidly interlocked with each other by snapping the notches on an arm and feet of one module to narrowing gaps at the openings of neighboring modules. The assembly requires no additional parts and tools. Thus it is easy to assemble and the manufacturing cost is low. Yet the structure of the assembly is rigid due to the interlocked arms and feet of the modules.
