Patent CA-2196464-A1 (CA)
Title: System for selectively transmitting messages to passers-by
Inventor: KUSNIER JAIME HECTOR
IPC: G09F25/00
Filed: 1997-01-31
Abstract: A system for transmitting messages from fixed transmitters to mobile receivers, for example supermarket push carts includes mobile receivers, so that whenever a push-cart comes within the range of a transmitter, an exclusive link is set up therebetween for relaying to the receiver an audio message prerecorded in the transmitter for the push-cart user to hear. The receivers beam each "listening" control signals within a predetermined range, in response to which a transmitter within the range of one such receiver relays back a "sending" control signal and sends its prerecorded message which the receiver tunes into. The control signals are single-frequency signals modulating infrared carriers. The message signals are recorded preferably in analog solid-state memories and frequency-modulating radio or infrared carriers in different embodiments. Other uses include public galleries and museums, where one such receiver may be carried by the user instead of installed in a cart.

Title: A crashworthy landing gear for an aircraft
Inventor: DELMONTE BERARDINO
IPC: B64C25/60
Filed: 1995-11-08
Abstract: A shock strut assembly (10) for an aircraft landing gear includes a trunnion fitting (12), a compressible oleo strut subassembly (14), a wheel subassembly (16), an energy dissipating subassembly (50), and a mechanical fuze subassembly (60). The oleo strut subassembly (14) includes a cylinder member (24) having an upper end mounted in combination with the trunnion fitting (12) by means of the mechanical fuze subassembly (60). The energy dissipating subassembly (50) includes a cylindrical cutter member (52) secured in combination with the cylinder member (24) and the trunnion fitting (12) and a frangible tube member (58) mounted in concentric combination with the cylinder member (24). The mechanical fuze subassembly (60) includes a shear ring (62). During normal landings, the shear ring (62) prevents movement of the cylinder member (24) with respect to the trunion fitting (12) in a crash landing, the shear flanges (66) shear at a predetermined axial load failure limit, which allows the cylinder member (24) to be displaced relative to the trunnion fitting (12). Displacement of the cylinder member (24) causes the frangible tube member (58) to interact with the cutter member (58) to interact with the cutter member (52), causing fracturing of the frangible tube member (58) for crash landing energy dissipation.

Patent CA-2211661-A1 (CA)
Title: Trickle power supply
Inventor: LECH DAVID ALLEN
IPC: H02M7/155
Filed: 1997-07-28
Abstract: A trickle power supply for a light switch module according to the invention enables power to an electronic circuit to be taken directly off the hot line.  The power supply operates under what is referred to as the "switched leg theory".  All power is taken off the standard switched leg of the light circuit.  The power supply bleeds enough current to power its electronic circuitry without turning on the load device, i.e., the light.  At the same time, the maximum current to the load is limited to prevent shorting out of the power supply which would effectively disable the switch module.

Patent CA-2228151-A1 (CA)
Inventor: GALI CARL
IPC: F02P15/10
Filed: 1996-10-16
Abstract: The invention is an automotive ignition system in which a high voltage source (11) is connected to and supplies a continuous RF high-voltage to each spark plug wire (17, 18, 19, 20). The high voltage is capacitively connected to each spark plug wire by placing metal clips (13, 14, 15, 16) on each one of the wires (17, 18, 19, 20) and connecting the high voltage source (11) to each of the metal clips (13, 14, 15, 16). The metal clip and spark plug wire conductor form the two plates of a capacitor with the spark plug wire insulation acting as the dielectric of the capacitor. The application of the high voltage to the spark plug wires produces a continuous corona discharge at the tip (26, 27, 28, 29) of each of the spark plugs in the combustion chambers. The engine head may also be used as one of the corona discharge surfaces.

Abstract: There is provided the combination of a corrugated solar collector panel and a building surface to which it is attached, in spaced relationship. At least some of the panel corrugations are flat and located such that they face in the general direction of the sun during at least a portion of the daylight hours. Generally uniformly distributed apertures are provided in the panel, and specifically at flat areas in the corrugations. The combination further includes photovoltaic cells mounted to the corrugations at flat portions thereof containing the apertures, with the cells being supported substantially parallel with and adjacent to but spaced apart from the flat surfaces, thus leaving air passages between the photovoltaic cells and the solar collector, whereby air can enter and leave the enclosed space by flowing through the air passages and along the undersides of the photovoltaic cells, thus removing excess heat build-up from the voltaic cells. In a variant, the photovoltaic cells are incorporated into individual panels adapted to span several corrugations.
