Title: Fiber optic sensor for magnetic bearings
Inventor: MEINZER RICHARD A
IPC: F16C32/04
Filed: 1996-06-03
Abstract: A fiber optic sensor for magnetic bearings includes a stator (12), a rotor (14), and an optical transmit/receive fiber (50) which propagates transmit light (112) which is launched across a gap (15) between the stator and the rotor and which receives reflected light (114) that is reflected off of the rotor (14) and travels along the fiber (50) as the light (116). The gap (15) distance is determined by the change in intensity of the return light (114). The transmit/receive fiber (50) may be located radially through or longitudinally along the stator (12). The receive light (116) is detected by a photodetector (120) which provides an electrical signal to a control circuit (124) which controls electromagnetic coils (31-34) of the magnetic bearing. Alternatively, two separate fibers may be used for the transmit and receive light. Also, time or wavelength multiplexing may be employed to allow for remote optical source and detection/control of the gap (15) distance. Further, a plurality of such sensors may be used around the gap (15). Also, a temperature sensor may be embedded within the distance sensor. Further, radial and/or axial gaps may be measured.

Patent CA-2213381-A1 (CA)
Inventor: SHARPLES JAMES HENRY
IPC: A47J27/21
Filed: 1996-02-19
Abstract: L'invention concerne un procédé permettant de commander le fonctionnement d'un élément électrique (11) d'un appareil utilisé pour chauffer du liquide (10), tel qu'une bouilloire électrique, ledit procédé consistant par exemple à couper le courant alimentant ledit élément dès que le liquide bout. Selon ce procédé, un capteur (14) mesure la température de l'élément (11) à intervalles de temps réguliers prédéterminés. Un microprocesseur (15), qui est relié au capteur (14) et à un circuit de temporisation (16), peut déterminer la vitesse de variation de la température de l'élément (11) à tout moment après la mise en marche de l'appareil. De cette façon, ledit microprocesseur peut détecter le moment où la vitesse de variation de la température de l'élément (11) dépasse un seuil prédéterminé, qui a été calculé en fonction de la puissance nominale de l'élément électrique, à la suite d'une période de chauffe initiale prédéterminée pour cet élément (11). Le microprocesseur (15) peut ainsi commander l'organe (12) qui permet de couper ou de faire varier l'alimentation électrique de l'élément (11) en fonction de la différence entre ladite vitesse de variation constatée et ladite valeur prédéterminée. De cette manière, l'appareil peut servir à détecter un bouillonnement initial du liquide lorsque les bulles de vapeur, qui se forment initialement à l'intérieur du liquide, se rassemblent à la surface dudit élément et l'isolent du liquide pendant un laps de temps limité, provoquant simultanément un accroissement plus rapide de la température de l'élément.

IPC: G06T15/10
Filed: 1996-11-08
Abstract: L'invention concerne un dispositif et un procédé permettant de générer une représentation d'un ensemble de données d'un objet ou d'un tissu. Deux ensembles de données de représentation d'image sont générés, pour l'objet ou le tissu, par un scanner à tomographie numérisée ou à résonance magnétique ou par tout autre procédé de visualisation connu. Le second ensemble de données est de préférence généré avec un contraste accru entre le tissu d'arrière-plan et le tissu cible à étudier, tel que les vaisseaux sanguins, amélioré par l'injection, par exemple, d'un produit de contraste vasculaire. Le premier ensemble de données est visualisé sous la forme de valeurs de données multiples voisines réunies, chaque groupe de valeurs voisines entourant de préférence une valeur de données centrale. Chaque valeur de donnée du second ensemble est comparée à des valeurs voisines du premier ensemble. Si la valeur de données du second ensemble est incompatible avec les valeurs voisines, il en est conclu que la valeur de données du second ensemble est représentative du tissu cible à contraste amélioré et elle est donc utilisée pour générer l'ensemble de données images final du tissu cible.

Title: Automatically locating individuals utilizing a combination of wireless media
Inventor: MORAN JOHN C
IPC: H04W4/90
Filed: 1998-10-28
Abstract: Transmitting identification codes of fixed units by wireless telephones to a central computer via a wireless switching system. The central computer uses the identification codes to locate the wireless telephones. Since a wireless telephone already has the capability for communicating utilizing a wireless protocol, the only additional cost to the wireless telephone is the ability to receive the transmission from the fixed units. The wireless telephones use a first wireless media for transmission, and the fixed units use a second wireless media for transmission. Further, each fixed unit consist only of a transmitter. The second media maybe infrared or ultrasonic transmission. If the wireless telephone fails to detect a fixed unit, the wireless telephone transmits this fact back to the central computer. This is done so as to determine locations that are not serviced by a fixed unit and also to detect failed fixed units. The central computer maintains a log of fixed units with which a wireless telephone had been previously identified. This allows the central computer to determine where there is a need for a fixed unit or which fixed unit has failed. The fixed units can be battery operated. When the controller controlling the fixed unit determines that the battery is reaching a low state in the fixed unit, the controller transmits this information along with the identification code so that the low battery indication can be relayed to the central computer.
