Patent CA-2200108-A1 (CA)
Title: Mechanical/electrical displacement transducer
Inventor: JACOBSEN STEPHEN C
IPC: G08C21/00
Filed: 1990-10-03
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Patent CA-2202311-A1 (CA)
Title: Self-monitoring line interface circuit
Inventor: CHEN ROBERT KUO-WEI
IPC: H04Q3/42
Filed: 1997-04-10
Abstract: A line circuit whose circuit components are selectively controllable by a microprocessor/DSP to provide normal BORSCHT functions or to be selectively tested without need for an electromechanical relay to isolate the line circuit from the loop conductors.  The conventional line transformer is advantageously replaced by a loop current feed resistor network and either a high voltage or a lower voltage battery may be connected to provide loop current to the resistor network through a current regulator circuit and battery switch circuit.  In normal operation, an ac feedback path, which includes the line receive amplifier, increases the terminating impedance above the dc value of the feed resistors so the loop termination resistor network may match the characteristic impedance of the loop at the audio frequencies employed.  In the testing mode, the microprocessor/DSP selectively applies or denies power to the line driving and receive amplifiers as well as to a level shifting circuit interposed between the codec analog output and the input to isolate or include these components or to provide a codec loop-back path.  The condition of the dc feed resistors and protective fuses, the condition of the loop closure detector and of the ringing generator are reported to the microprocessor/DSP over the same terminal normally used for reporting the on-hook and off-hook status of the loop.

Title: Improved counter weight door
Inventor: TOEWS WALTER
IPC: E05D15/24
Filed: 1997-04-16
Abstract: The present invention relates to an improved counter weight door of the type for use at an opening in a wall of a building. The counter weight door includes door panels comprising two or more standard sized overhead door panel sections which are joined together by a pair of J-shaped channel members. A  pair of hinge connectors have be mounted side by side at each side of each door panel and adjacent the joint between adjacent top and bottom edges of adjacent door panels The axle of the guide rail follower has been lengthened to allow it to extend through an elongate tubular member on each of the pair of hinge connectors.  This gives each pivot connection additional strength and yet allows standard overhead door hinges to be used. Improved pulley mounts allow the pulleys to be easily arranged and secured above and to the side of the opening in the wall, and lie substantially in the plane of the door. Mounting the pulleys directly on the guide rails helps the installer mount the pulleys such that their axis of rotation lies substantially perpendicular to the plane of the door. This helps ensure smooth operation of the pulleys as the door is opened and closed.
Patent CA-2204980-A1 (CA)
Inventor: GU XIJA
IPC: G01M9/06
Filed: 1997-05-09
Abstract: The present invention provides a new synchronized optical method for measuring surface pressure on rotating objects such as propellers or other rotating objects. The technique is based on the phenomenon of oxygen quenching of luminescence coatings and synchronized optical imaging. A surface coating, referred to as a pressure sensitive paint (PSP), is formed by mixing photo-luminescence molecules in an oxygen permeable polymer. The luminescence excited by an appropriate light source decreases as the oxygen concentration rises due to quenching. As a result, the luminescence intensity of light emitted from the coating varies as a function of the partial pressure of oxygen. A digital camera measures the luminescence intensity distribution over the object and the pressure distribution can be computed.
