Title: Improved data compression apparatus and method therefor
Inventor: MANSBRIDGE JOHN
IPC: G02F1/01
Filed: 2001-04-17
Abstract: Routers for trunk telecommunication systems currently operate at 2.SGb/s. Next generation routers will be requires to switch 128 input data streams into 128 output data streams, each data stream being at a data rate of 10Gb/s. Current routers employ massively parallel electronic switches to route data at 1.25Gb/s. Such technology is reaching its limit and a new approach to high-speed switching is required. The present invention provides an apparatus and method for enabling such high-speed switching by providing a data compression apparatus which comprises a pulsed chirped laser (226) coupled to a modulator (218, 220), the modulator (218, 220) being coupled to a multiplexer (232) and a compressor (228). A chirped laser pulse having the duration of a data packet is modulated with data received on an input channel and then passed through the multiplexer (232) and the compressor (228) in order to generate a compressed modulated data pulse for high speed switching.
Patent CA-2399830-A1 (CA)
Inventor: LI DAOBEN
IPC: H04J13/12
Filed: 2000-02-17
Abstract: The invention discloses a method for spread spectrum multiple access coding in any radio digital communication system containing code division multiple access (CDMA) and spread spectrum technologies. It uses two quadrature synchronous fading transmission channels respectively for transmitting two spread spectrum address code blocks, which have opposite and complementary attributes when running, thereby making their correlation having zero correlation window characteristics. That is, correlation functions and intercorrelation functions between various address codes within zero correlation windows do not have side peaks. It makes the corresponding CDMA  and spread spectrum systems be able to completely cancel intercode interference and multiple access interference, establishing a basis for super large capacity radio digital communication systems, in order to resolve progressive conflicts between frequency resources and communication capacities.

Inventor: BERN MARSHALL W
IPC: G06V30/10
Filed: 2002-09-03
Abstract: A method for matching an original document image with a copy image is disclosed. The original document image is defined as an ensemble of blocks, each of the blocks having neighboring blocks. A mask is formed for each of the blocks by dilating foreground pixels included in the block. A best match is searched in the copy image, for each of the blocks, using a search window, by correlating pixels in the mask with pixels in a corresponding portion in the copy image. Each of the best matches has a matching score. Each of the blocks is indicated as "unmatched" when the corresponding matching score is less than a matching threshold. A displacement vector is computed for each of the matched blocks.

Title: Method and system for aligning moving sheets
Inventor: DACUNHA STEVEN J
IPC: B65H9/10
Filed: 2002-10-18
Abstract: A method and system for aligning a moving stack of sheets. A pair of cams, positioned on opposite sides of the moving stack, rotate synchronously to each other but in opposite directions. When the stack approaches the cams, the distance between the outer surfaces of the cams is wider to the stack width to receive the stack. As the stack moves forward further, the distance between the cam surfaces is reduced so as to allow the cam surfaces push the sheets toward a center line until the distance between the cam surfaces is substantially equal to the width of the sheets. In a sheet collator where sheets are moved by a plurality of finger pairs which are linked to a moving chain, the cam can also be linked to the moving chain so that their rotation is synchronous to motion of the stacks.
