Patent CA-2432973-A1 (CA)
Inventor: KOMORIYA AKIRA
IPC: C07K7/08
Filed: 2001-12-21
Abstract: The present invention provides for novel reagents whose fluorescence or absorption spectra change upon cleavage or a change in conformation of a backbone. The reagents comprise a backbone (e.g. nucleic acid,polypeptide, etc.) joining two chromophores (e.g. fluorophores) of the same species where by the chromophores form an H-dimer resulting in quenching of the fluorescence of the fluorophores or a change in absorption spectra of the chromophores. When  the backbone is cleaved or changes conformation, the chromophores are separated, no longer forming an H-type dimer, and are de-quenched thereby providing a detectable signal. The use of a single chromophore rather than a n "acceptor-donor" fluorescence resonance energy transfer system offers synthesis and performance advantages.

Title: Production of ultra pure salt
Inventor: BECNEL LAWRENCE F JR
IPC: C25B15/08
Filed: 2003-08-28
Abstract: This invention relates to methods and installations for producing ultra pure sodium chloride salt cyrstals primarily for use in saturating depleted brine resulting from the electrolytic decomposition of saturated brine in chlor alkali membrane cells for the production of chlorine, caustic soda and hydrogen. More particularly, this invention relates to the production of ultra pure sodium chloride salt crystals by processing primary treated brine by first acidifying the primary treated brine, then stripping the carbonic acid produced by acidification as carbon dioxide, and then returning the brine to a pH of about 6 or higher which is sufficient for processing it in evaporation equipment where the ultra pure salt crystals are produced.

Abstract: An improved scheduling technique for software pipelining is disclosed which is designed to find schedules requiring fewer processor clock cycles and reduce register pressure hot spots when scheduling multiple groups of instructions (e.g. as represented by multiple sub-graphs of a DDG) which are independent, and substantially identical. The improvement in instruction scheduling and reduction of hot spots is achieved by evenly distributing such groups of instructions around the schedule for a given loop.
Patent CA-2439697-A1 (CA)
Title: Interference suppression methods for 802.11
Inventor: SHERMAN MATTHEW J
IPC: H04L1/16
Filed: 2002-03-04
Abstract: An 802.11 source station (160-1) transmits a signal with the duration field other than that required for the transmission to prevent transmission by other stations during known sequences.  Thus, the source station (160-1) uses the duration field to spoof the actual time the medium will be occupied, to stations within range of the signal. A station (160-4) within range for the transmitted signal will check the duration field of the transmitted signal, and update the station network allocation vector.

Patent CA-2442800-A1 (CA)
Inventor: STOODLEY MARK G
IPC: G06F9/44
Filed: 2003-09-26
Abstract: An improved method and system for acquisition and release of locks within a software program is disclosed. In an exemplary embodiment, a lock within a loop is transformed by relocating acquisition and release instructions from within the loop to positions outside the loop. This may significantly decrease unnecessarily lock acquisition and release during execution of the software program. In order to avoid contention problems which may arise from acquiring and keeping a lock on an object over a relatively long period of time, a contention test may be inserted into the loop. Such a contention test may temporarily release the lock if another thread in the software program requires access to the locked object.

Title: Combining markers with location information to deliver domain-specific content to devices
Inventor: ASHMORE BRADLEY C
IPC: H04L12/28
Filed: 2002-04-04
Abstract: A system and method provides content to a mobile device (130, 140) in response to a marker (141) received from the device and an associated context. A mobile device user initiates delivery of content or another action by entering the marker into the mobile device. The mobile device transmits the marker to a mobile network support system (100) having a context server (126) for supplying a context for the marker. The support system forms a message including the marker and context, and sends it to a content server (110). The content server (110) uses the context to map the marker to a domain, retrieves from a content database (111) the content identified by the marker and domain, and sends the content to the mobile network support system or performs another action with the content. The mobile network support system then transmits the content back to the mobile device.

Title: Sequential inverse encoding apparatus and method for providing confidential viewing of a fundamental display image
Inventor: STRUYK DAVID A
IPC: G09G5/00
Filed: 2002-07-30
Abstract: An image altering apparatus which provides confidential viewing of a video display by means of time multiplexing the fundamental display image with a color-inverted image thereof on a pixel-by-pixel basis. Electronic circuitry and/or software are utilized to modify the fundamental image signal by time multiplexing its color data components with corresponding inverse color data components to generate a compound image signal which is representative of a substantially featureless image. Different multiplexing sequences of color data components and inverse color data components may be utilized at varying duty cycles to generate a compound image which is highly confidential and secure from unauthorized viewing. The fundamental image may be decoded and viewed only by those viewing the encoded image through specially designed eyeglasses incorporating time synchronized LCD shutters, variable polarizers, or color filters, which can selectively block inverted color components and/or demodulate the fundamental image to allow only the true fundamental color components to pass, thereby providing confidential and highly secure viewing of the fundamental image by the viewer.
