Abstract: In a first aspect, the invention is directed to an illumination system for rearward illumination for a first vehicle. The illumination system includes a tail lamp assembly, a sensor and a controller for controlling the operation of the tail lamp assembly. If the controller determines that there are any oncoming second vehicles behind the first vehicle that are sufficiently close to the first vehicle, then the controller operates the tail lamp assembly in one mode. If the controller determines that there are no oncoming second vehicles behind the first vehicle that are sufficiently close to the first vehicle, then the controller permits the operation of the tail lamp assembly in another mode.

Abstract: A starting circuit for an electric discharge lamp providing an electric current to a lamp having a first and a second filament. The circuit measures a lamp current and a filament temperature and then compares these against a reference voltage. When the lamp current is below a set threshold value, a relay contact disposed between the first and second filament is closed to direct the electric current through the first and second filaments to initiate pre-heating of the lamp. Once the filament temperature exceeds a set threshold, the relay contact is opened and the electric current passes through heated gas inside the lamp.

Abstract: A valve plate (54) is slidably moved on a frame (52) by an actuator (62) between open and closed positions to control the supply of air sucked into the inlet (44) of a blower system (40) that supplies pressurized air through an outlet (46) to a plenum (12) for distribution to said nozzle (16, 18). By disposing the valve plate (54) at the inlet, the blower motor (49) may run continuously without a load as the impeller is not pumping air when there is no demand to blow the water from a vehicle.

Abstract: A plurality of pairs of telescoping tubes (20) and (22) interconnect a support plenum (12) and a nozzle system (14) for delivering air from the plenum (12) to the nozzle system (14) while allowing the nozzle system (14) to move in an adjustment direction toward and away from the plenum (12).

Abstract: A plurality of bags (16), each of a substantially rectangular cross-section defined by spaced and parallel bag panels (18) interconnected by shorter sides (20), have inlets respectively connected to a support plenum (12) and extend to a distal end (22). An elongated nozzle (24) extends across each bag (16) at the distal end (22) between the sides (20) and converges from the bag panels (18) to a nozzle opening (26) for directing air toward the object. The assembly is characterized by a plurality of nozzle gussets (32) each including two layers (34) of flexible material suspended between the first and second nozzle panels (30) for bulging away from one another and toward the next adjacent nozzle gusset. Consequently, the spaced layers (34) of next adjacent nozzle gussets (32) bulge toward one another in response to air flow through the nozzle (24) to create a restriction and increased velocity of the air flow.

Also, the second starboard 44 and port 47 bags are spaced downstream from the first 43 starboard and port 46 bags. The nozzles 52 of the first starboard bags 43 are disposed in a first horizontal V.sub.a.

Abstract: An assembly for blowing liquids from the surfaces of a vehicle comprising support plenum (10) for distributing a stream of air to the surfaces of a vehicle, a blower (16) connected to said support plenum (10) for producing the stream of air, and an overhead bag (18) extending downwardly from the plenum (10) to a distal end. A nozzle is disposed at the distal end and includes a center section (20) having a length (Y) extending horizontally between ends for directing air against the top of a vehicle. The nozzle is characterized by including an inwardly directed end section (22) at each end of the center section (20) to define outward tips (24) of the nozzle for directing air downwardly and inwardly against the sides of a vehicle. A positioner (30) positions the vehicle to combine with the geometric configuration of the overhead bag (18) to assure that the stream of air emitted from the nozzle tips (24) impacts the sides of the vehicle.
