Patent CA-2069858-C (CA)
Inventor: GOTO SEIJI
IPC: G01R31/36
Filed: 1992-05-28
Granted: 1997-09-23
Abstract: A current measuring circuit for measuring discharging current and charging current of a battery, which is selectively connected to a load and a charger.          The current measuring circuit comprises a resistor connected in series with the battery having a sufficiently low resistance value as not to substantially restrain the output current from the battery and a differential amplifier for amplifying a potential difference between both ends of the resistor.          By providing a switch for short-circuiting one input terminal and the other input terminal of the differential amplifier, an offset/drift voltage of the differential amplifier can be obtained.  This offset/drift voltage is used for correcting the output voltage from the differential amplifier at the time of current measurement and, thereby, the discharging current and charging current of the battery can be measured accurately.

Abstract: A clip is disclosed for mounting a flush plate such as a mounting tray or the like within a corresponding opening in an extruded frame member such as a transom bar, door frame, or the like. The clip includes a pair of tongue members held together in spaced apart relation by an interconnecting bridge member. The tongue members are inserted into corresponding channels defined in the extruded frame member adjacent the opening, and when the clip is thus mounted to the frame member, a portion of the clip extends into the opening. In the disclosed embodiment, the bridge member is located to abut the end of the extruded frame member to limit the depth to which the clip is inserted into the channels. With the clips thus mounted, the flush plate is fastened to the clips to secure the flush plate to the extruded frame member. The clip is less expensive to produce than two corresponding single tongued clips and requires only one installation step rather than two. Further, the clip prevents the possibility of it being overdriven into the extruded frame member and reduces or eliminates the possibility of the clip being bent or twisted during installation. The clip also increases the accuracy of alignment of bores in the clip with corresponding apertures in the flush plate.

Title: Antenna diversity receiving system for eliminating reception interference in mobile television signal reception
Inventor: LINDENMEIER HEINZ
IPC: H04N5/44
Filed: 1991-02-08
Granted: 2000-09-19
Abstract: Antenna diversity receiving system for mobile reception of television signals having N antenna inputs, one diversity processor with as many inputs, and connected downstream in the system to a television receiver, the video signal of the television receiver and the line and picture synchronizing signals being applied to the diversity processor. The diversity processor comprises a time gate circuit which is opened by the line synchronizing pulses during the line blanking interval and switches the video signal through to the signal quality evaluation circuit. At that location an output signal having the signal quality of the video signal is produced which is applied to the control circuit. In the case of an imminent picture disturbance the control circuit produces an address signal so that very rapidly a new antenna signal or a linear combination derived from the antenna signals is applied to the television receiver by means of the antenna combiner. Particularly advantageous is the fact that during the line blanking interval the signal quality of all available HF signals is tested and the one HF signal having the best signal quality is switched through to the television receiver during the remaining time interval.

Granted: 2001-01-30
Abstract: An apparatus for grinding an elongated knife blade used in a veneer lathe or a veneer slicer has a blade mount with a mounting surface on which the blade is fixed. In order to prevent a thermal distortion of the cutting edge of the blade after it has been ground by the grinding wheel and naturally cools, the blade mount and the blade thereon are cooled by supplying a cooling medium even to an intervening surface or area therebetween. The blade and mount are also cooled entirely by direct contact with the cooling medium. The grinding wheel is controlled such that when it is lowered to abut against the blade, a resistance torque increase is detected and the grinding wheel is raised slightly to a grinding start level from where the grinding feed and stroke of the wheel is started so that interference between the wheel and the blade is prevented during the initial longitudinal stroke of the wheel along the blade.

Title: Secure telecommunications
Inventor: FAUCHER DAVID W
IPC: H04Q3/545
Filed: 1994-07-18
Granted: 1998-08-25
Abstract: A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via the security node, and providing appropriate control signals to the node, the information may be encrypted only over a portion of the transmission path between the parties, and clear over the remainder of the transmission path. Alternatively, the information may be encrypted in different portions of the path using different encryption algorithms. This arrangement enables the parties to obtain relatively secure communications even if only one party has a security device at the originating or terminating end, or if the parties have security devices using different handshaking protocols and encryption algorithms.
