Patent CA-2031004-A1 (CA)
Inventor: MEDZIUS JOSEPH
IPC: G01N27/00
Filed: 1990-11-28
Abstract: ABSTRACT          A moisture sensor to sense rain on a windshield includes sensor members and leads on the outboard surface of the windshield. The members and leads are uncoated and directly exposed to any moisture accumulation on the sensor.  Leads connect the sensor to a controller which includes a signal generator and sensor monitor.  The relative spacing between the leads as compared to the spacing between the sensor members is such that the impedance of the sensor when the leads are electrically interconnected by moisture is measurably different from the sensor impedance when said members or said members and leads are electrically interconnected.  In response to the latter signal, the windshield wipers are actuated.

Abstract: Abstract of the Disclosure A containment device for minimizing soil contamination in filling underground storage tanks, comprises a bucket member, a bottom member and a bellows connection between the bottom member and a riser pipe extension.  These elements comprise an upwardly open spillage container.  A lower bellows connects the bottom member and the riser pipe extension, comprising a lower chamber.          The containment device is mounted on the riser pipe of an under-ground tank by threading the lower end of the riser pipe extension thereon.  A valve controlled passage, through the bottom member, permits spilled fuel to be drained from the spillage container into the lower chamber and then through openings in the riser pipe extension into the storage tank.  The bottom member is releasably secured to the bucket member and the bellows are releasably clamped to the riser pipe extension, to permit these items to be removed from the bucket member for repair and replacement.  In an alternate embodiment there is no lower chamber and the upper bellows is releasable clamped directly to a storage tank riser pipe.  In another embodiment the upper and lower bellows are formed as portions of an elastomeric separating member.  In order to control the installed orientation of the bucket, adjustable mechanism is provided for establishing a desired position of the upper end of the bucket member relative to the riser pipe extension.  Also described is a bayonet connection between the bucket member and a mounting rim; a dam arrangement from preventing ground water from entering the spillage container; and wire anchors for insuring a firm connection between the containment device rim and a concrete apron which overlies the storage tank.

Filed: 1991-11-21
Abstract: Abstract of the Disclosure A bus arbitration system is capable of granting access to an expansion bus to devices following two-wire bus arbitration protocol or a three-wire bus arbitration protocol.  The bus arbitration system receives a plurality of bus request signals from a plurality of devices.  Each bus request signal is made up of one or more coded pulses and has a predetermined priority.  A priority encoder receives the bus request signal and assigns a priority level to each bus request signal.  An arbiter determines and stores in memory which bus request signal has a highest priority and whether the device follows two-wire bus arbitration protocol or a three-wire bus arbitration protocol.  The expansion bus grants access to the bus to the device having the highest priority once a previous device if any, has relinquished the bus.

Patent CA-2067730-A1 (CA)
Title: Vehicle security system
Inventor: GARLICK TREVOR S
IPC: G01V3/10
Filed: 1991-08-28
Abstract: A vehicle security system comprises first and second conductive loops (A and B) for attachment to a vehicle (C) in substantially parallel relationship with a gap (D) between them. Each loop is connected to an associated first amplifier (1, 2) the outputs from which are connected to a differential amplifier (3) which is arranged to sum the output signals received from the first amplifiers. The output from the differential amplifier (3) is connected to a threshold detector (4) which sets a latch (5) to store an alarm condition when a moving magnetic field is detected. The alarm condition signal is interrogated remotely by, for example, an infrared remote control link (8, 11) to activate an alarm (7). As a moving magnet field is passed across the gap between the two loops (A, B) a voltage is induced in each loop and the first amplifiers (1, 2) detect the induced voltage and the differential amplifier (3) determines a phase shift in the two voltages. This phase shift indicates that a moving magnetic field has passed over the gap between the two loops (1, 2), and indicates the possibility of a magnetic bomb device having been attached to the vehicle.
