Patent CA-2161342-A1 (CA)
Title: Medical gas insufflator with automatic gas flow control
Inventor: OGNIER JEAN-FRANCOIS
IPC: A61M13/00
Filed: 1995-02-23
Abstract: Medical device for use in diagnostic and surgical endoscopy, comprises an insufflation path (4, 5, 6) for injecting a neutral gas into a surgical cavity (2), in conjunction with a pressurized neutral gas source, and a flow control pilot valve provided in said path. A means (18) for measuring the insufflation pressure (Pi) is provided at the beginning of the injection path (4, 5, 6). The pressure within the cavity (Pa) is calculated based on the insufflation pressure (P), by evaluating the load loss in the path. A comparison is made between the calculated pressure within the cavity (Pa) and the flow control valve (13) is guided as a fuction of the result of the comparison with the set value. The apparatus hence provides a minimum continuous neutral gas flow (D) to closely compensate the gas leaks occurring outside of the surgical cavity (2).

Title: Method for moving carriage assembly from initial position to target position relative to storage medium
Inventor: GETREUER KURT WALTER
IPC: G11B17/02
Filed: 1996-01-24
Abstract: A method for moving a carriage assembly from an initial position to a target position relative to a storage medium rotating at a circumferential velocity. The method includes the steps of determining a first radial distance between the initial position and a center of the storage medium, determining a second radial distance between thetarget position and the center of the storage medium, determining a circumferential distance between the initial position and the target position, determining an initial circumferential velocity of the storage medium, calculating a velocity trajectory relative to the first radial distance, the second radial distance, the circumferential distance, and the initial circumferential velocity, and moving the carriage assembly from the initial position to the target position substantially at the velocity trajectory. The velocity trajectory is calculated such that the carriage assembly will arrive radially and circumferentially at the target position at substantially the same time. Additionally, a target circumferential velocity may be determined, the rotation of the storage medium may be changed from the initial circumferential velocity to the target circumferential velocity, and the velocity trajectory is further related to the target circumferential velocity.

Abstract: Moyen sélectif de démodulation à l'intérieur d'un récepteur donné de signaux potentiellement soumis aux nombreux types de dégradations qui peuvent survenir dans les sytèmes mobiles de radiocommunications, et de sélection des meilleurs résultats en vue d'une amélioration significative des performances. Selon ce procédé, lorsqu'un signal HF est reçu, il est échantillonné et les échantillons sont démodulés selon des schémas à la fois cohérents et non cohérents dont le plus adéquat est choisi en fonction de la qualité des performances de chacun des démodulateurs. La démodulation cohérente fournit les meilleurs performances lorsque le signal subit d'importantes pertes sur un trajet, mais pas d'affaiblissement; la démodulation non cohérente fournit les meilleurs performances lorsque le signal subit de faibles pertes sur un trajet mais un affaiblissement important.

Patent CA-2183592-A1 (CA)
Inventor: SENGUPTA UPAL
IPC: H02J7/00
Filed: 1996-08-15
Abstract: The invention is a battery management circuit and corresponding method for controlling the in-circuit charge and discharge of series-connected electrochemical cells. The invention finds particular application in the field of devices powered by rechargeable alkaline manganese dioxide cells, but also finds application in other types of chargers, devices and electrochemical cells or batteries. The battery management circuit of the invention monitors the voltage of individual series-connected cells that power a device.  The circuit terminates discharge of all cells as soon as the voltage of one of the cells drops to a predetermined level.  During in-circuit charging of the cells, the battery management circuit monitors the voltage of individual series-connected cells as they are being recharged, and terminates the provision of charging current to all cells as soon as one of the cells attains a sufficiently high predetermined voltage.  Appropriate termination of the provision of charging current to the cells combined with the appropriate termination of the provision of discharging current from the cells, permits the cells to provide a maximum number of discharge/charge cycles.  The invention permits rechargeable cells to provide greater cumulative coulometric capacity, and reduces the incidence of electrolyte leakage from rechargeable cells.  The cells may be contained in a battery pack, or may be mounted directly in a device. Electronic circuitry and software programmable device embodiments of the invention are described.

Title: Apparatus for destroying hazardous compounds in a gas stream
Inventor: JENKINS GEORGE M
IPC: C23C16/50
Filed: 1996-11-04
Abstract: An apparatus having a first and second zones, for destroying hazardous compounds of a first and second types respectively present in a gas stream. The first zone has a first live electrode and a ground electrode. The first live electrode and the ground electrode define a first gas passage. These electrodes are excitable at a first energy level for generating a first electric field capable of generating a plasma in a gas flowing through the first gas passage. The second zone has a second live electrode spaced apart from the ground electrode. The second live electrode defines with the ground electrode a second gas passage communication with a downstream end of the first gas passage. The second live electrode is excitable at a second energy level for generating with the ground electrode a second electric field capable of sustaining the plasma in the gas flowing through the second gas passage. The second live electrode is located within electrically excitable distance from the first live electrode, whereby when the first energy level is different from the second energy level, either in their respective voltages, phases or frequencies, a third electric field is generated between the first and second live electrodes. This third electric field provides an additional source of energy between the first and second electric fields for sustaining the plasma throughout both zones, and for preventing a backward recombination of the hazardous compounds of the first type leaving the first zone.
