Abstract: Video composition techniques are disclosed for processing video information from a plurality of sources to provide a video image having a plurality of rectangular regions. Each rectangular region displays video information from a specific one of the plurality of video sources. The video information from each video source is in the form of an incoming digital bit stream. The digital bit stream from a first video source has a first bit rate, and the digital bit stream from a second video source has a second bit rate where the first bit rate may or may not be equal to the second bit rate. The incoming digital bit streams are fed to a rate matching circuit which converts all incoming digital bit streams to a common bit rate.

Patent CA-2190625-A1 (CA)
Title: Sensor and method for detecting predetermined chemical species in solution
Inventor: LARUE REBECCA A
IPC: G01N33/543
Filed: 1995-05-19
Abstract: A chemical sensor for measuring a change in the sensor mass relating to the interaction of a surface of the sensor with a solution comprises a crystal detector oscillator capable of providing a measurement signal based upon the resonant frequency of the crystal detector oscillator.  The crystal detector oscillator has a first crystal side for contacting the solution, and a second crystal side isolated from contacting the solution.  A first electrode is integral to the first crystal side, with the first electrode having an inner and outer perimeter defining an outer portion of the first crystal side which is exterior to the outer perimeter of the first electrode and an inner portion of the first crystal side which is interior to the inner perimeter of the first electrode.  A second electrode is integral to the second crystal side.  The sensor may be employed to detect the concentration of predetermined species in solution by adsorbing a predetermined species-specific complementary material such as an antibody onto the active crystal sites of the first crystal side, and thereafter contacting the first crystal side with the species-containing solution, thereby causing adsorption of molecules of the predetermined species onto the complementary material-absorbed active crystal sites.  The difference in the measured resonant frequencies of the complementary material-adsorbed sensor and the complementary material plus species-adsorbed sensor is indicative of and may be correlated with the concentration of the predetermined species in solution.  The sensor may also be used to measure the change in sensor mass relating to the degradation of a coating applied to the first crystal side thereof.  The apparatus of the invention comprises the chemical sensor operatively coupled to detecting means for detecting the resonant frequency of the crystal detector oscillator and providing a detector output signal representative of the crystal detector oscillator resonant frequency.  The apparatus may additionally comprise display means operatively coupled to the sensor detecting means for displaying the detector output signal.

Title: Braided body balloon catheter
Inventor: CHEE URIEL HIRAM
IPC: A61F2/958
Filed: 1996-11-29
Abstract: This is a balloon catheter having braided layer which extends generally from the proximal end of the catheter to a location distal of the balloon. In particular, it is desirable that the shaft of the catheter proximal of the balloon be stiffest at the proximal section and least stiff just proximal of the balloon. Although the catheter may be a single lumen catheter using some type of a core wire to act as a valve for inflation and deflation of the balloon, it is within the scope of the invention to include either a separate inflation/deflation lumen or one incorporated into the various concentric polymeric layers used to make up the proximal shaft. Particularly preferred is the use of an elastic, compliant balloon.

Title: Oral Compositions
Inventor: VERNON PETER GEORGE
IPC: A61K8/40
Filed: 1995-09-20
Abstract: The invention relates to oral care products such as toothpastes with an improved sensorially-perceivable cleaning benefit. This is achieved by the inclusion in the oral care products of agglomerates, substantially free from organic and/or inorganic binding agents, whereby the agglomerates are made of at least two chemically and/or physically different particulate materials of specified particles sizes. The inclusion of materials having a therapeutic benefit on the teeth or gums in the agglomerates such as zinc citrate provides for a further benefit in that this material is slowly released from the agglomerates, thus providing for a delivery of this material over a longer period. Upon use, the gritty-feeling agglomerates will break-down into smaller particles, thus giving the consumer the feeling of initial cleaning and subsequent polishing.

Title: Agent dispenser and method and apparatus for introducing an agent into aliquid or gas at a controlled rate
Inventor: BUTLER ERNEST
IPC: C02F1/28
Filed: 1997-03-18
Abstract: The present invention provides an agent dispenser, a method and an apparatus for introducing an agent into a liquid or gas where the agent is miscible with such liquid or gas.
