Patent CA-2128127-A1 (CA)
Title: Method and system for data compression
Inventor: DIMITRI THOMAS J
IPC: H03M7/40
Filed: 1994-07-15
Abstract: Disclosed is a method and system for data compression. In a preferred embodiment, an input stream of data bytes are compressed into an encoded stream using an LZ77-based scheme. The preferred method searches for a matching sequence of already processed data bytes that is identical to a current sequence of bytes. Sequences of literals (bytes not forming part of a matching sequence) or match codes (encoded matching sequences) are identified by count values indicating the number of literals or match codes in the sequence. Preferably, the encoded stream is transmitted from a first computer to a second computer, where the encoded stream is decompressed. The method uses matching circular history buffers for compression and decompression, the history buffers being synchronized using a coherency byte included with each frame of encoded data transmitted. If an encoded frame is not received by the decompression device, the decompression device transmits a flush request to the compression device. The compression device flushes its history buffer in response to the flush request, the flushing step making the previously processed bytes stored in the history buffer incapable of becoming part of a matching sequence. The compression device includes in the coherency code of the next encoded frame a control code indicating whether a flush request has been received by the compression device.

Patent CA-2128317-A1 (CA)
Title: Differential separation assay
Inventor: MANIAN BALA S
IPC: G01N21/77
Filed: 1992-06-29
Abstract: An electrophoresis-based assay system for detection of one or more target substances, i.e. an analyte tagged with fluorescent binding agents. The analyte is reacted with an excess amount of fluorescently tagged binding agent. The reaction mixture is subjected to electrophoresis and the migration of bound and free fluorescent substances are timed at a location where there is a spatial and optical differentiation of the two substances. An optical detector supplies signals corresponding to fluorescent amplitudes of the two substances. The free fluorescent substance arrives at a time expected from calibration runs. The optical signal is a marker for a second time, either earlier or later, when bound substrate should have arrived. Recorded data is searched to establish the relation between free and bound dye among the recorded optical signals. An absence of a bound dye signal infers the absence of target analyte in a sample. The amounts of bound and unbound amounts of the same fluorescent substance may be related by ratio of amplitudes of the optical signals so that the amount of target analyte may be estimated.

Inventor: GOATER GEORGE H
IPC: B65G47/88
Filed: 1994-10-20
Abstract: A lumber lug loader for placing boards onto a lugged transfer deck is disclosed.   The lug loader has a lower board accelerating deck and an upper board-contacting member.  The lower board accelerating deck and the upper board-contacting member have driven moving surfaces which can be clamped against the board from above and below.  Because the boards are clamped while they are being accelerated to the speed of the lugged transfer deck, the boards can be subjected to high  acceleration  without  excessive  slipping  or significant damage to the boards.   The boards are accelerated  smoothly  and  quickly.    This  design therefore allows for operation at higher speeds than is possible with previous lug loaders.  The lug loader also provides a movable overhead stop.  In operation, boards are accumulated on a  smooth transfer deck behind the stop.  When a board is present at the stop and a row of lugs on the lugged transfer deck is approaching the correct position for loading the stop is retracted and the moving surfaces of the upper and lower  board-contacting  members  are  brought into forcible  contact  with  the  board.    The  board  is accelerated between the upper and lower board-contacting members.  After the board is accelerated it is carried to and deposited on the lugged transfer deck.  While the board is being accelerated the stop is put in place behind the board.   The cycle is repeated each  time  a  row  of  lugs  on  the  lugged transfer deck passes.  This accomplishes reliable high speed  loading  of  individual  pieces  of  lumber (singulating), onto the lugged transfer deck, at the correct position relative to the lug.

IPC: B41J2/07
Filed: 1995-07-19
Abstract: A recording apparatus is to perform complementary recording in order to eliminate the white streak caused by recording elements becoming incapable of recording while recording an image.  Particularly, in an ink jet recording method for recording an image by discharging ink from nozzles, the white streak caused by nozzles becoming incapable of discharging ink can be eliminated by the performance of a complementary recording in accordance with the present invention.    Preceding printing, abnormal nozzles are detected, and then, data related to such abnormal nozzles are removed.  In accordance with such data, one scan printing is performed.  Preceding the returning operation of the printing head subsequent to the one scan, a sub-scanning feed is performed so that normal nozzles are positioned in a location corresponding to the white streak appearing in the one scan printing.          In this way, while returning the printing head, the printing is performed in accordance with such data related to the abnormal nozzles detected at the time of one scan, hence executing a complementary recording appropriately.

Title: Process and arrangement for the electrolytic deposition of metal layers
IPC: C25D21/14
Filed: 1994-12-23
Abstract: For the electrolytic deposition of uniform layers of metal having given physical-mechanical properties, particularly of copper, soluble anodes are not used, since their geometrical shape is changed by the deposition and therefore the distribution of the lines of force in the electrolytic cell are continuously changed.      In order to solve the problems occurring in this connection, a process has been proposed in which compounds of a redox system added to the plating solution are converted during the deposition on the insoluble anodes. The compounds produced in this connection dissolve new metal ions from a reservoir which contains parts of the metal to be deposited, so as again to supplement the metal ions removed form the solution by deposition.      The present invention describes a procedure in which, differing from the prior art, the addition compounds are not destroyed.
