Patent CA-2472502-A1 (CA)
Inventor: ROUSSY RICHARD B
IPC: A61G7/05
Filed: 2004-06-25
Abstract: An electrically activated emergency system for a patient bed comprises: an electrically powered linear actuator for driving a back rest of the patient bed from a lowered back rest position to a raised back rest position and operable to permit the back rest to lower from the raised back rest position to the lowered back rest position without being driven by the linear actuator; and, an independent emergency back rest lowering feature comprising an electrical activation means for activating the linear actuator to permit the back rest to lower from the raised back rest position to the lowered back rest position without being driven by the linear actuator, the electrical activation means not requiring continued operator attendance for continued lowering of the back rest. The present invention permits an attendant, for example a nurse, to press a single button to bring the back rest to a lowered back rest position without having to keep the button pressed so that the attendant is free to immediately begin administering emergency procedures while the back rest is lowering.

Title: Speech recognition enhanced caller indentification
Inventor: OLLASON DAVID G
IPC: G10L17/00
Filed: 2004-07-16
Abstract: A process for collecting the identity of a telephone caller is disclosed. In one embodiment, a personalized Context Free Grammar (CFG)(212) is created for each potential call recipient (210), and is configured to support identification of incoming callers utilizing voice recognition. Each CFG (212) incorporates an indication of high probability callers and probability weights in each CFG are altered accordingly. When a recipient (210) receives a call (202), the relevant CFG (212) is applied in association with a voice recognition application (222) to enable at least a preliminary identification of the caller. In accordance with another embodiment, the caller confirms identifications. In accordance with one embodiment, standard caller-ID functionality (224) is utilized if possible at least to assist in the caller identification process. In accordance with still another embodiment, voice recognition enhanced caller identification is utilized to provide intelligent call routing functionality (226).

Title: Electronic compass system
Inventor: BUGNO MARK D
IPC: G01C17/30
Filed: 2003-02-28
Abstract: An electronic compass system (100) includes a magnetic sensor circuit (102) having at least two sensing elements (104, 106, 108) for sensing perpendicular components of the Earth~s magnetic field vector. A processing circuit (110) is coupled to the sensor circuit to filter, process, and compute a heading. The processing circuit further selects an approximating geometric pattern, such as a sphere, ellipsoid, ellipse, or circle, determines an error metric of the data points relative to the approximating pattern, adjusts the pattern to minimize the error, thereby obtaining a best fit pattern. The best fit pattern is then used to calculate the heading for each successive sensor reading provided that the noise level is not noisy and until a new best fit pattern is identified. The electronic compass system is particularly well suited for implementation in a vehicle rearview mirror assembly (140).

Title: Diode laser comprenant une partie d'amplification qui presente un indice de refraction variable
Inventor: UNGAR JEFFREY E
IPC: H01S5/10
Filed: 2003-03-04
Abstract: L'invention concerne une diode laser haute puissance comprenant une partie en bande pompée qui présente un indice de réfraction variable. L'indice de réfraction variable peut réduire le phénomène d'autofocalisation présent dans les diodes laser haute puissance de la technique antérieure, ce qui permet d'obtenir un faisceau de sortie de haute qualité. L'indice de réfraction peut varier d'un côté de ladite partie en bande pompée à l'autre côté de celle-ci. L'indice peut varier par variation d'une caractéristique structurale de ladite partie en bande pompée, de type dopage ou épaisseur des couches à l'intérieur de la diode laser. Un gradient thermique peut être créé sur toute la surface de ladite partie en bande pompée afin de faire varier l'indice de réfraction. Ce gradient thermique peut être créé par intégration d'un élément thermique le long d'un côté de ladite partie en bande pompée, ou par création d'un flux de courant inégal à travers celle-ci.

Title: Ac-dc converters with bi-directional valves
Inventor: VITHAYATHIL JOHN J
IPC: H02M3/00
Filed: 2003-05-14
Abstract: An ac-dc converter has bi-directional thyristor valves (VR1-VF6) made up of back-to-back connected thyristors as converter valves. The bi-directional thyristor valves (VR1-VF6) permit operation of the converter as a rectifier or an inverter with both polarities of the voltage across the dc terminals (DCH, DCL) of the converter. The bi-directional valves (VR1-VF6) can be used to prevent the reversal of the polarity of the dc voltage across the dc terminals (DCH, DCL) of the converter or to minimize the magnitude of the reverse voltage. The bi-directional thyristor valves (VR1-VF6) can be used to provide protection against overvoltage across the converter valves and eliminate or reduce the energy rating of converter valve arresters. AC-DC converters could also be provided with some bi-directional thyristor valves as converter valves while retaining regular thyristor valves in other converter valve positions.

Patent CA-2485894-A1 (CA)
Title: Methods and apparatus for reducing artifacts in mass spectrometers
Inventor: STOTT WILLIAM R
IPC: G01N27/62
Filed: 2003-05-29
Abstract: The invention addresses the problem of artifact ghost peaks which can sometimes arise in mass spectrometers that employ a quadrupole rod set for both trapping and mass analyzing the trapped ions. The problem arises as a result of randomly distributed voltage gradients along the length of the rod s. Three solutions are presented. The first approach involves improving the conduction characteristics of the rod sets. The second approach involves the application of at least one continuous axial DC field to the trapping quadrupole rod set in order to urge ions towards a pre-determined region of the trap, thereby avoiding voltage gradients. Another approach involves the application of one or more discrete axial fields to create one or more potential barriers along the axial dimension of the trap (in addition to the barriers used to initially trap the ions). These barriers prevent ions of differing voltage gradients from equilibrating with one another.

Title: Method of determining depth of compressions during cardio-pulmonary resuscitation
Inventor: BERGER RONALD D
IPC: A61H31/00
Filed: 2003-10-23
Abstract: A method of processing a raw acceleration signal, measured by an acceleromet er- based compression monitor, to produce an accurate and precise estimated actu al depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression i s then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (suc h as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.
