Title: System and method for updating a sleep id of a mobile station in a bwa communication system
Inventor: KANG HYUN-JEONG
IPC: H04W28/00
Filed: 2005-08-17
Abstract: A system and method for updating a sleep identifier (SLPID) of a mobile station (MS) in a broadband wireless access (BWA) communication system having a sleep mode in which there is no transmission data and an awake mode in which there is transmission data. Upon recognizing a need to update an SLPID  allocated to an MS in the sleep mode in the initial phase of the sleep mode, a base station (BS) reallocates a new SLPID to be allocated to the MS and transmits SLPID update information to the MS. Upon receiving the SLPID update information for its current SLPID during the sleep mode, the MS updates its current SLPID with the reallocated SLPID according to the received update information.

Title: Recursive filter system for a video signal
Inventor: MITCHELL ARTHUR
IPC: H04N9/64
Filed: 2007-05-25
Abstract: A recursive filter system 10 for a video image includes a memory 14 to store a first image of stored picture elements S(x,y). Weighted values W(x,y) of luminance and chrominance of a stored picture element S(x,y) are obtained by summing weighted values B(x,y).S(x,y) of luminance and chrominance of the picture element and neighbouring picture elements. A first proportional parameter A(xy) is generated for the stored picture element based on a modular sum of differences between luminance and chrominance of the stored picture element and of surrounding picture elements.  The first proportional parameter A(x, y) is used to generate a weighted picture element M(x,y) from a proportion of the stored picture element S(x,y) and a complementary proportion of the weighted value W(x,y). Picture elements C(x,y) of a next image and a second proportional parameter K are input and a filtered image generated by combining a proportion K of each input picture element of the next image with a complementary proportion 1-K of the weighted stored picture element M(x,y) of the first stored image using the second proportional parameter K. The filtered image is stored for processing a next succeeding image. In embodiments of the invention the second proportional parameter K may be varied pixel to pixel dependent on noise, motion and detail in a region of a picture element being processed.
