Patent CA-2091843-A1 (CA)
Inventor: WHITAKER LOUIS G
IPC: E05F15/00
Filed: 1993-03-17
Abstract: A light beam transmitter and receiver are located in or near a door opener enclosure, and fiber optics connect the transmitter and receiver to the sides of the door opening.      Lens arrangements are attached to the ends of the optic cables and are mounted near the bottom of the door frame. Thus, the transmitter and receiver do not need to be located near the door which eliminates the need for wiring from the enclosure to the door area and protects the transmitter arid detector from physical abuse at the doorway.

Patent CA-2100475-A1 (CA)
Title: Adaptive leak hdtv encoder
Inventor: KNAUER SCOTT C
IPC: H04N7/50
Filed: 1993-07-14
Abstract: An improved predictive encoder where the leak signal is a function of the buffer fullness of the encoder. More specifically, the signals stored in theencoder output buffer are further encoded based on the fullness of the buffer, and information about this further encoding is used in determining the leak factor level. In accordance with another improvement, this leak factor level is not constrained to granularity that is imposed by the decoder hardware. Removal of the constraints is accomplished by cycling through a sequence of permissible leak levels that averages at the desired level.

Title: Speech Decoding Apparatus Comprising Alarm Signal Generator Operable on Deterioration of Transmission Path Quality
Inventor: FUJIWARA RYUHEI
IPC: H04L1/00
Filed: 1993-08-12
Abstract: In a speech decoding apparatus (100) supplied with an input speech signal (101) comprising successive blocks, each comprising a digital speech signal and an error detecting code signal, an error detector (8) detects an error in the digital speech signal by the error detecting code signal for each block to produce error detection pulses whenever the error detector detects the error.  The error detector also produces the digital speech signals of the blocks.  A speech decoder (9) decodes the digital speech signals of the blocks into an analog speech signal.  A measuring circuit (102) measures, as a measured value, the number of the error detection pulses during a predetermined time interval.  A comparator (15) compares the measured value with a reference value to produce a command signal when the measured value is greater than the reference value.  A generator (12) generates an alarm signal in response to the command signal.
Patent CA-2104661-A1 (CA)
Title: Method of fabricating sign panels
Inventor: WILSON JEFFREY
IPC: G09F7/02
Filed: 1993-08-23
Abstract: Abstract The present invention relates to a method of assembling structural and non-structural panels into a durable, aesthetically pleasing composite sign panel. The layers of the sign panel consist of a reusable structural mount on which a flexible graphics panel is applied through the use of an adhesive or the like.  On top of the flexible panel, a transparent layer of a durable sheet material, such as a laminate is applied. Text and graphics are printed onto the face of the flexible panel before application of the transparent laminate facing, thus resulting in coverage and protection of the graphics.  The method of making the sign panels is cheap, quick and easy to use. Contact between the structural mount and the flexible panel is such that the latter can be easily removed thereby allowing for reuse of the structural mount when the graphics of the sign panel must be changed. Alternatively, new graphic layers can be placed successively on top of one another when a change is to be made.

Patent CA-2109383-A1 (CA)
Title: Printed circuit board
Inventor: DUXBURY GUY M
IPC: H05K1/02
Filed: 1993-10-27
Abstract: ABSTRACT OF THE DISCLOSURE   A plurality of pairs of parallel conductive wires are supported by a flexible non-conductive sheet, equidistant from two conductive ground meshes which sandwich the wires therebetween. Each mesh forms a matrix, defining an array of intersecting conductors. The offset of the intersections from the conductive wires incrementally changes along the longitudinal axes of the pair of conductive wires. This ensures the capacitance between each conductive wire and the mesh is substantially balanced regardless of where the conducive wires run, so that cross talk between the pairs of conductive wires will remain relatively low.
Patent CA-2109522-A1 (CA)
Title: High power ac traction inverter cooling
Inventor: BAILEY RONALD B
IPC: H05K7/20
Filed: 1993-04-22
Abstract: A plurality of high power semiconductor devices (42) are connected in circuit with at least one electric traction motor for controlling electric power to the motor. The semiconductor devices are each thermally connected between a pair of generally hol-low heat sinks (36A, 36B) adapted for passing cooling air therethrough for extracting heat therefrom. M anode terminal of the devices is coupled to one of the heat sinks of a pair and a cathode terminal of the devices is connected to the other heat sink of the pair. Each of the heat sinks are mounted in a cantilever fashion to a common air plenum forming one wall of an electrical circuit area of the vehicle. The distal ends of the heat sinks of a pair are coupled together by an air how conduit (38) thus forming a con-tinuous air passage through the pair of heat sinks which begins and ends at the surface containing the air supply plenum. Cooling air is then directed into the end of the other heat sink, circulating through the one heat sink and out through the exhaust conduit (40). In this manner, the cooling air is held in a closed path extending into the electrical circuit area so that contaminants are not deposited on the electrical components.

IPC: A63B49/08
Filed: 1993-11-29
Abstract: ABSTRACT GAMES RACKET A   badminton   racket   with   improved   playing qualities  is  provided  by  including  a modified  joint where  the  shaft  enters  the handle.   The  flexibility of  the  shaft in a direction in a plane through its axis  perpendicular  to  the  plane  of  the  strings  is increased but is substantially unaffected in a direction in a plane through its axis parallel to the plane of the strings.   This is achieved by anchoring the shaft through  an  elastic  joint  which  is  flexible  in  the direction  perpendicular  to  the  plane  of  the  strings but substantially rigid in the direction parallel to the plane of the strings, whereby the shaft can pivot about the point where it enters the handle.
