Patent CA-2250368-A1 (CA)
Inventor: OKADA SETSUO
IPC: G06F3/038
Filed: 1998-10-14
Abstract: A power supply control apparatus which reduces power consumption in an information-input apparatus is provided. The control apparatus includes a power supply unit and a control unit.  When the operator discontinues moving of a mouse, an X-encoder and a Y-encoder attached to the mouse stop outputting of pulse signals.  The control unit allows a timer to start according to stopping of the pulse signals from the X-encoder and the Y-encoder.  When a predetermined period of time elapses after the start of the timer, the timer outputs a timing signal to the control unit.  According to the timing signal, the control unit controls the power supply unit so as to lower the power supplied from a battery in the power supply unit from normal level to a predetermined lower or zero level.  If the operator moves the mouse or clicks the mouse button before the predetermined period elapses after the start of the timer, the controller causes the timer to stop so that the power supply from the battery is kept at the normal level.

Title: Motor controlled surgical system and method having self clearing motor control
Inventor: KRAUSE KENNETH W
IPC: A61B17/32
Filed: 1997-04-04
Abstract: A surgical system, adapted to operate with at least one surgical device, has a handpiece containing a motor which is adapted to receive the surgical device. The surgical device is driven through a continuum of positions by the motor output shaft. A controller microprocessor controls the operation of the system. The motor has sensors for generating electrical position signals and the controller is responsive to input signals for defining both a stop position and a reversal position for the surgical device. As a result, the controller initiates operation of the surgical device at the so called stop position and stops operation of the surgical device so that it comes to rest substantially at the stop position. In an oscillatory mode of operation, the controller also forces reversals to occur at a reversal position dictated by the system, under the control of the user, unless a stall condition is sensed, in which case the reversal takes place as soon as possible. In connection with an arthroscopic cutting device, the control enables the surgeon to control, for example, the opening of the aperture through which tissue and fluids are removed from the surgical site during the reversal and start/stop conditions.

Patent CA-2266877-A1 (CA)
Inventor: THEURER JOSEF
IPC: E01B27/17
Filed: 1999-03-25
Abstract: For correcting the position of a track, the track (3) is tamped into a preliminary target position and subsequently, in the course of a track stabilization, is ultimately lowered in a controlled way into a final target position by applying a static load in connection with transverse vibrations.  The preliminary target position created by tamping the track (3) is measured, and a final target position eliminating long-wave track position faults is computed. While determining correction values (35) representing the difference between the final target position (34) and the preliminary target position (31), the static load and/or transverse forces acting on the track (3) are changed according to the correction values in the course of a track stabilization in order to achieve the final target position of the track (3). Thus it is possible to eliminate in particular long-wave faults in the course of the stabilization of the track.

Character specifying data for specifying a character and a font ID for specifying the font of this character are stored in a layout information file and transmitted from the client computer to the server. On the basis of a layout information file, the server retrieves character image data (a bitmap text file) expressing the character as an image. The server transmits the found character image data to the client computer. When character image data cannot be found, the character image data is generated and is then transmitted from the server to the client computer.

Title: Network element with a controller, and control method
Inventor: BANZHAF MONIKA
IPC: H04L12/24
Filed: 1999-05-17
Abstract: A network element (NE) for a communications network, particularly for a synchronous digital communications system, is disclosed. It comprises a controller (CT) which contains a processor (CPU) for executing an access request (REQ), a memory (MEM) in which managed objects (MO) are stored, and an access unit (ACC) for receiving the access request (REQ).      The controller controls the network element by means of the managed objects (MO). The managed objects are images of the static and dynamic properties of resources of the network element (NE). The memory (MEM) stores a service profile (PRO) which contains information about access rights to the managed objects (MO). Before executing the access request (REQ), the processor (CPU) checks whether access rights to managed objects (MO) needed to execute the access request (REQ) are present. This permits more flexible and less error-prone management of the access rights to managed objects, particularly during communication between managed objects.

Patent CA-2278120-A1 (CA)
Title: Automatic answering pick-up device
Inventor: BRITTO SUSAN J
IPC: H04M1/72502
Filed: 1998-02-09
Abstract: A cordless telephone headset and remotely controlled telephone handset pick-up device for use in conjunction with an existing corded telephone set. A  mechanical lift arm of the pick-up device, driven by an electric motor with a slip clutch, lifts the handset away from the corded telephone cradle, placing the telephone handset in an off-hook position. The handset is lowered back onto the cradle by the mechanical lift arm, returning the telephone set to an on-hook position. The mechanical lift arm is activated and deactivated in response to a radio signal indicative of the lowering and raising of the microphone boom of the cordless headset. The slip clutch provides sufficient force to gently and reliably raise and lower the telephone handset without causing misalignment between the handset and the cradle and without causing damage. As the handset is gently lowered over the hook switch, the motor drives the lift arm downward beyond a point at which the handset is expected to be lowered into the cradle, ensuring that the telephone is reliably placed on-hook, while the slip clutch limits the amount of force that can be applied to the telephone set. The telephone set rests upon a platform coupled to the lift-arm, providing a unitary structure for the telephone set and handset pick-up device which aids in maintaining proper alignment of the handset to the cradle by preventing the lift arm from forcing the pick-up device out of alignment.

Filed: 1998-07-09
Abstract: L'invention concerne un procédé permettant d'appliquer un revêtement électrocatalytique ou protecteur sur un substrat de métal ou de réparer une région endommagée d'un tel revêtement. Ce procédé consiste à soumettre un précurseur de ce revêtement catalytique à un traitement thermique appliqué au moyen d'un jet d'air chaud émis par un dispositif de soufflage. La température du substrat est contrôlée localement par des détecteurs de température superficielle ou par un système de mesure à infrarouge. Le substrat de métal peut être une structure électrode épuisée, auquel cas la réactivation peut être facilement réalisé sur place, sans qu'il soit nécessaire d'envoyer la structure au producteur. Ce procédé convient particulièrement à la réactivation des anodes destinées au dégagement d'oxygène, car il permet d'éviter la délicate opération consistant à détacher l'anode du conducteur électrique.
