Patent CA-2341208-A1 (CA)
Title: Method of multichannel data compression
Inventor: KOSTRZEWSKI ANDREW A
IPC: H04N19/103
Filed: 1999-08-19
Abstract: A method for compressing multiple channels using an MPEG-compatible technique (Fig. 10: block 96). The method encodes differences between frames within and among each channel (Fig. 10: blocks C1, C2, and CN). Some frames are predicted and some are skipped. Differences between the current and predicted frames for each channel are compared to a threshold E0 for each successive group of frames, after each group of each channel is encoded. If, for any of the groups of frames, the difference between the current and predicted frames of any of the channels reaches the threshold, the method inserts an I-frame into the sequence of encoded frames, to restart encoding.  Computing the differences and encoding I-frames is implemented for both intra-and inter-channel differences. The encoded frames are transmitted to a decoder for display.  The method uses artificial intelligence or fuzzy logic.

Patent CA-2345380-A1 (CA)
Inventor: BEU STEVEN C
IPC: H01J49/10
Filed: 1999-10-13
Abstract: The ionization efficiency of a mass spectrometer is increased by creating a potential well between the electron source (12) and the electron collector (20). The potential well is created by applying to the collector a reflectio n potential having an amplitude which is the same as or substantially the same  as the amplitude of the potential applied to the electron source and a polarity which is the same as the polarity of the electron source potential.  The potentials applied to the electron source and electron collector are relative to the ionization region effected between the source and collector.  Many of the electrons produced by the electron source oscillate back and for th in the potential well thereby allowing those electrons a greater opportunity  to interact with sample molecules to thus increase ionization efficiency.</S DOAB>

Patent CA-2349998-A1 (CA)
Inventor: ZHOU ZHIHONG
IPC: E21B33/138
Filed: 2001-06-05
Abstract: A method is provided for blocking high permeability regions in subterranean geological formations, using a reinforced swelling clay gel. A reinforced clay slurry is prepared by mixing swelling clay, such as bentonite, an aqueous solution containing the salt of certain cations, which inhibit clay swelling, and a reinforcing agent. The cations K+, Ca2+, Mg2+, Cs2+, Fe2+, Al3+ and NR4+, where each R can independently be H, CH3, C8H5, or CH2CH3, and combinations thereof, among others, are clay swelling inhibitors. The reinforcing agent is non-swelling particles, including, without limitation, particles of produced sand, silica sand, sandy or silty soil, crushed rock, minerals, mine tailings, and combinations thereof. The reinforced clay slurry is introduced into a geological formation, where it preferentially enters high permeability regions. There the slurry is contacted by NaCl brine solution present in natural or injected drive fluids, and the inhibitive cations bound to the clay particles are replaced by Na+  ions, which attract water molecules and promote clay swelling. The reinforced Na+-clay swells, causing the slurry to acquire a gel-like consistency. The reinforced clay gel so formed is capable of controlling the flow of at least a majority of a fluid into or from a high permeability region.

Title: Transporting data transmission units of different sizes using segments of fixed sizes
Inventor: JANOSKA MARK WILLIAM
IPC: H04L29/06
Filed: 2001-10-05
Abstract: A data traffic management system that has the capability of writing data to the buffer memory at twice its normal rate. The data traffic management system uses a pointer structure that can reference either a single or a dual segment memory bank. A dual segment memory bank enhances the write capability of the data traffic management system by allowing two segments to be simultaneously written to both segment memory banks, with one segment being written to each bank. A pointer data structure with a single/dual indicator (S/D indicator) is used for referencing the memory banks. If the S/D indicator has a D entry, then a dual segment memory bank is addressed. The S/D indicator will have an S entry if a single segment memory bank is addressed.      Based on the contents of the S/D indicator, either a single fixed size data segment is written to a single memory bank or two fixed size data segments are written to a dual segment memory bank.
