Title: Method and system for client-server interaction in interactive communications
Inventor: ELEFTHERIADIS ALEXANDROS
IPC: H04N7/24
Filed: 1999-01-29
Abstract: In an interactive communication system based on MPEG-4, Command descriptors along with Command Route nodes or Server Routes in the scene description can be used to support application-specific interactivity. Content selection can be supported by specifying the presentation in command parameters, with the command ID indicating that the command is a content selection command. An initial scene can be created with several images and with text that describes a presentation associated with an image. Associated with each image and the corresponding text is a content selection descriptor. When a user clicks on an image, the client transmits the command containing the selected presentation and the server starts a new presentation. The technique can be used in any application context, as generally as HTTP and CGI can be used to implement any server-based application functionality.
Patent CA-2324695-A1 (CA)
Title: Switching circuitry providing improved signal performance at high frequencies and method of operation thereof
Inventor: ILIASEVITCH STEPAN
IPC: H03K17/687
Filed: 2000-10-26
Abstract: The invention relates to transistor switching circuitry which allows to reduce the influence of the parasitic capacitance of the transistor and provides improved signal performance at high frequencies. The circuitry according to the first embodiment of the invention comprises an NMOS transistor whose source is connected to the input means having an output resistance R2, and whose drain is connected to the output means having an input resistance R3. The gate of the transistor is connected to a control means having an output resistance R1 and generating a control signal which opens or closes the transistor. By arranging that R1 » R2 (and assuming that R1 ~ R3), high frequency circuitry characteristics of the switching circuitry are dramatically improved. The switching circuitry of the invention provides high frequency voltage gain approaching unity and phase shift between the output and input voltages approaching zero, i.e. ensures no signal degradation. Ten alternative embodiments of the invention describe various implementations of the switching circuitry. The switching circuitry of the invention has numerous applications, e.g. in power down circuits, video or telephone switches, or any other application where the required frequency of switching may be lower than the transmitted frequency. Corresponding methods of connecting/disconnecting two circuitry points along a signal path and controlling voltage gain and phase shift characteristics are also provided.

Inventor: BARDY GUST H
IPC: A61B5/361
Filed: 2000-11-09
Abstract: An automated system and method for diagnosing and monitoring the outcomes of atrial fibrillation is described. A plurality of monitoring sets is retrieved from a database. Each of the monitoring sets include recorded measures relating to patient information recorded on a substantially continuous basis.  A patient status change is determined in response to an atrial fibrillation diagnosis by comparing at least one recorded measure from each of the monitoring sets to at least one other recorded measure. Both recorded measures relate to the same type of patient information. Each patient status change is tested against an indicator threshold corresponding to the same type of patient information as the recorded measures which were compared. The indicator threshold corresponds to a quantifiable physiological measure of a pathophysiology resulting from atrial fibrillation.

Patent CA-2333769-A1 (CA)
Inventor: OLSCHEFSKI ROBERT D
IPC: G01M15/04
Filed: 1999-05-25
Abstract: An arrangement for testing engines for vehicles and other drive train assemblies employs magnetic clamping to achieve fixation of the rotatory drive train assembly to a drive arrangement. When the rotatory drive train assembly is a vehicle engine, there is a need to affix a measurement head that contains sensors to the engine. This too is effected by magnetic clamping. A robotic transport device or overhead crane conveys the engine to a testing station where a human operator guides the drive arrangement into position on the engine. When the engine and the drive arrangement are appropriately aligned the operator will actuate a switch that activates electromagnets to effect the fixation of the engine to the drive arrangement. A human operator also guides the measurement head to the engine, and it is magnetically clamped thereto.  When it is desired to release the engine from the drive arrangement, a deactivation switch that is manipulable by the operator discontinues the electrical energy to the electromagnet, except for a degaussing signal that utilizes the electromagnet to dissipate residual magnetism in the engine. A  similar degaussing process is employed upon disengagement of the measurement head.
