Title: Method and system for providing feedback from a non-destructive inspection of a composite part
Inventor: JANSEN SANDRA L
IPC: G01N29/44
Filed: 1999-07-30
Abstract: A computer-implemented method for providing on-line ultrasonically scanned images of composite parts for immediate feedback in a manufacturing environment is discussed. The scanned images are edited to indicate each deficiency that has been repaired on a previously assembled composite part. Quality assurance personnel enter data associated with each composite part and verify the data content. Repair personnel enter data associated with correcting an identified deficiency of the composite part. Historical data suitable for developing statistics and trends are stored for each type of composite part. When queries are launched, the statistical and trend data is filtered to produce reports that are displayed. That is, reports are generated that identify particular statistics and trends. The scan image and data associated with a composite part are linked together for cross-referencing and stored in a database that is accessible by client and server computers on a network. Images produced by an ultrasonic scanner(s) coupled to the network are stored for retrieval.
Patent CA-2279595-A1 (CA)
Inventor: POLLUTRO DENNIS C
IPC: B41J2/41
Filed: 1991-03-26
Abstract: A method of operating an electrostatic printer which prints, with an acceptable determinable print quality, electrostatic images on a dielectric utilizing electrostatic discharges at an electrostatic region formed by application of a predetermined voltage high enough for good print quality while not significantly adversely affecting printer components, and utilizing a depletable source of gas under pressure which is supplied to the region of electrostatic discharge effective to prolong the life of printer components, comprising the steps of sequentially: (a) upon a degradation in the print quality, increasing the voltage effective to cause the electrostatic discharge, so as to increase print quality to approximately said acceptable determinable level; (b) removing the source of gas under pressure once it is depleted, and connecting up a new source of the gas so that it is supplied to the region of electrostatic discharge; and (c) returning the voltage effective to cause electrostatic discharge back to approximately its value prior to the practice of step (a); said steps (a)-(c) practiced without interrupting printer operation.
Patent CA-2279750-A1 (CA)
Title: Phase-tunable antenna feed network
Inventor: HAMPEL KARL GEORG
IPC: H01Q3/26
Filed: 1999-08-04
Abstract: The invention is a device that provides a phase-tunable antenna feed network that allows beam-steering and beam-width variation with simple actuation, at low cost, and with high rf performance. The device provides a series-feed where signal power splitters and phase-shifters are alternately disposed in series. Each phase-shifter consists of reflection-mode phase-shifter elements that operate in conjunction with an isolation device. This avoids the critical resonance condition between periodically aligned phase-shifters over the entire tuning range, since the isolation devices can easily be matched and/or aligned with non-resonant spacing. The main feed-line interconnections have the same impedance, thereby enabling the utilization of the same phase-shifter design for the entire network. Moreover, a common driving mechanism can be used for the phase-shifters to steer the antenna beam. Splitting the array into two sub-arrays with individual collective driving mechanism further allows beam-width variation by steering the beams of both sub-arrays in opposite directions. The device is further compatible with symmetrical series network designs that have better frequency response. The series feed network preferably uses a phase-shifter for shifting a signal propagating through a transmission line by moving a conductive construct between an active line and a ground plane of the transmission line. The conductive construct capacitively couples with either the active line and/or the ground plane, forming a capacitive shunt that reflects a significant part of the signal. The remaining portion of the signal is reflected at a terminated end of the transmission line, resulting in substantially no signal loss.

Abstract: A transmitter-receiver includes a transmitting circuit for providing an output by converting the frequency of a transmission signal input thereto, a receiving circuit for providing an output by converting the frequency of a received signal input thereto, and a local oscillator which generates an oscillation signal having a local oscillating frequency based on a reference signal.   A local oscillator signal splitter is connected to the local oscillator and splits the oscillation signal into substantially similar transmit and receive oscillation signals each at the local oscillating frequency. The local oscillator signal splitter supplies the transmit oscillation signal to the transmitting circuit and supplies the receive oscillation signal to the receiving circuit. The transmitting circuit converts the frequency of the transmission signal in accordance with said transmit oscillation signal, and the receiving circuit converts the received signal into two intermediate frequency signals in accordance with the receive oscillation signal. A selectable switch operates to select one of the two intermediate frequency received signals for further processing by the unit.

Title: Improved turbine powerplant
Inventor: JAMES ROBERT G
IPC: F01D1/28
Filed: 1998-10-22
Abstract: A turbocompressor assembly (10) includes a first rotor stage (50) mounted on rotary shaft {51) and including circular rows of impeller blades (59-1, 59-2, 59-3) on one surface thereof separated by radial gaps in which opposed blade rows (29-1, 29-2) on a second rotor stage (20) are received. The two rotor stages are geared for counter-rotation and at least one of the rotors is perforated proximate its center (25) to allow air to be drawn between the opposed surfaces thereof, where its passage over the impeller blades develops useful torque. The opposed rotor surfaces are convolved to define a radially decreasing separation to an annular combustion cavity (73), and thereafter increasing with radius. Thus a radial compressor and a turbine function are developed by the respective blade rows on either side of the combustion cavity. The combustion cavity (73) may be formed in one of the rotors, or may be shared between the rotors as a communicating common annular chamber. Fuel may be delivered to the combustion chamber directly admixed into the air stream, or by a fuel delivery system (71).

Patent CA-2311504-A1 (CA)
Title: Robot ball
Inventor: CARON SERGE
IPC: A63H33/00
Filed: 2000-06-14
Abstract: The robot ball comprises an encapsulating shell, a drive system and a steering system. The shell has an axis of rotation and an outer annular tread surface centered on the axis of rotation. The drive system is encapsulated in the shell and comprises a first motorized mechanism and a counterweight. The first motorized mechanism has a stator portion and a rotor portion centered on the axis of rotation and connected to the shell. The counterweight is connected to the stator portion and is spaced apart from the axis of rotation whereby, due to inertia of the counterweight, rotation of this rotor portion rotates the shell to roll the tread surface on the ground. The steering system comprises a second motorized mechanism through which the counterweight is connected to the stator portion. This second motorized mechanism includes a pivot assembly having a pivot axis transversal to the axis of rotation. Therefore, activation of the second motorized mechanism rotates the counterweight about the pivot axis, tilts the axis of rotation, displaces the center of gravity of the robot ball, and thereby changes the trajectory of the robot ball. An inclinometer is mounted on the stator portion to measure an inclination of the stator portion about the axis of rotation, and a controller regulates the speed of rotation of the rotor portion in relation to the measured inclination. The robot ball further includes a second inclinometer so mounted on the platform as to measure an inclination about the pivot axis. The controller then controls the electric servomotor in relation to the measured platform inclination about the pivot axis.
