Patent CA-2200659-A1 (CA)
Inventor: STEVENS MARC P
IPC: G06T17/30
Filed: 1997-03-21
Abstract: A curve projected onto a NURBS surface defines trim regions on the NURBS surface. A plurality of spaced-apart points are defined on the curve and rays are project through the points toward a NURBS surface. Any intersections ofthe rays with the NURBS surface is mapped into the U,V domain. Corresponding points of adjacent rays are connected to define at least a portion of each trim region on the NURBS surface. Transitions on the NURBS surface between adjacent rays are detected based upon differences in the number of intersections of adjacent rays. The location of each transition is determined to within a selected tolerance by using a binary subdivision of the interval between adjacent rays. The location of suchtransitions is used to determine how intersections of the rays with the surface at the boundaries of the NURBS surface should be connected. Parity assigned to the raysat each intersection determines the direction in which intersections along the rays are connected. The technique enables real-time trimming of the NURBS surface to be carried out in response to any change to the curve and/or NURBS surface topology.

Title: Circuit arrangement for operating electric lamps
Inventor: RUDOLPH BERND
IPC: H05B41/292
Filed: 1997-04-02
Abstract: The invention relates to a circuit arrangement for operating electric lamps, having a free-running half-bridge inverter (Q1, Q2). An auxiliary transistor (T1, T2) is in each case connected into the control circuits of the half-bridge inverter transistors (Q1, Q2), so that the emitter impedance of each half-bridge inverter transistor (Q1, Q2) is formed by a parallel circuit which consists of at least one resistor (R5) or (R7) and the control path, arranged in parallel therewith, of the corresponding auxiliary transistor (T1) or (T2). The control inputs of the two auxiliary transistors (T1, T2) are, furthermore, connected to the output of a common control circuit (IC). These measures make it possible to switch over the effective emitter impedance and therefore the feedback of the half-bridge inverter (Q1, Q2) as a function of the operating phases of the lamp (LP) and thus, in simple fashion, to vary the clock frequency of the half-bridge inverter within wide limits by virtue of the dimensioning of the resistors (R5, R6; R7, R8) of the parallel circuits (R5, R6, T1) or (R7, R8, T2) according to the invention.

Title: Monitoring system for delivery of therapeutic gas
IPC: A61M16/06
Filed: 1995-11-21
Abstract: An apparatus (1) for monitoring and controlling the flow of a therapeutic gas to a patient. The apparatus includes a gas source (3), a flow management module (5) and an electronics module (7). The flow management module (5) contains a valve assembly (15) and a sensor (17). The valve assembly (15) contains a first valve (25) to control the inflow of the therapeutc gas. The second valve (27) controls the inflow of ambient air. When the valve assembly (15) is de-energized the first valve (25) is open allowing the flow of gas through the apparatus (1). The second valve (27) is closed. When the valve assembly (15) is energized, the first valve (25) is closed, stopping the flow of gas and the second valve (27) is open, allowing the inflow of ambient air. The sensor (17) senses changes in the flow of the gas or ambient air and transmits a signal to the electronics module (7). The electronics module (7) can be preprogrammed to control the valve assembly (1), determine respiratory rate, control the flow of therapeutic gas, store or transmit data in response to signals sent by the sensor (17).

Title: Multi-sector cell pattern for a wireless communication system
Inventor: HONCHARENKO WALTER
IPC: H04B7/26
Filed: 1998-11-30
Abstract: A packet-based wireless system is configured in accordance with a cell pattern which utilizes multi-sector directional cells. An illustrative embodiment utilizes a five-sector cell pattern, with five approximately 72° directional antennas in the base station of each cell. The assignment of frequency channels to cell sectors in the cell pattern repeats itself in six-cell groups throughout the system. This cell pattern allows the system to utilize a frequency reuse factor of one, such that substantially the same set ofcommunication channels may be used in each cell of the system. In other possibleimplementations of the cell pattern, the sector positions of the directional antennas may be arranged such that the sectors in a given cell are rotated by an integer or non-integer number of sectors relative to the sectors of a neighboring cell, or the sector positions of the directional antennas may be fixed for all of the cells. The invention can be used to increase the capacity of a non-CDMA wireless system without significantly increasing co-channel interference.
