Patent CA-2553654-A1 (CA)
Inventor: SMOLSKY MICHAEL
IPC: G06F21/64
Filed: 2004-01-21
Abstract: A technique for efficient representation of dependencies between electronically-stored documents, such as in an enterprise data processing system. A document distribution path is developed as a directional graph that is a representation of the historic dependencies between documents, which is constructed in real time as documents are created. The system preferably maintains a lossy hierarchical representation of the documents indexed in such a way that allows for fast queries for similar but not necessarily equivalent documents. A distribution path, coupled with a document similarity service, can be used to provide a number of applications, such as a security solution that is capable of finding and restricting access to documents that contain information that is similar to other existing files that are known to contain sensitive information.

Inventor: BROWN MARK L
IPC: A61B5/361
Filed: 2005-06-22
Abstract: A system and method for detecting and classifying cardiac arrhythmias based on cardiac pressure signals or the combination of cardiac electrical and cardiac pressure signals.

Patent CA-2589661-A1 (CA)
Inventor: MICHAELIAN ANDRE
IPC: A61C17/00
Filed: 2005-11-18
Abstract: A prophy device incorporating a shaft and one or more corrugated members which eliminate the need for plastic gears of the prior art is disclosed. The corrugated members effectively transfer rotational energy from a shaft to an applicator. In another version, a flexible paste chamber contains polish within a housing of the device. A difference between a rotational speed at a front of the paste chamber and rear of the paste chamber causes the flexible chamber to contract on itself thereby automatically forcing polish from the chamber and into a polish applicator. A user dictates the amount of polish dispensed by controlling the rotational speed at the front of the paste chamber by pressing the polish applicator against the teeth of a patient. As the speed differential increases, the amount of polish dispensed increases as well. The design is simple and cost efficient such that the design overcomes many shortcomings of the prior art.
