Abstract: A method and system for controlling the illumination of a vehicular lamp and for monitoring the state of a switch electrically connected thereto. A feedback signal corresponding to a state of the switch is generated by a feedback circuit. A control signal is generated by a controller based on the feedback signal. A lamp drive signal is generated by a lamp driver based on the control signal for illuminating the lamp. A single multiplexed connector provides the lamp drive signal to the lamp during a drive operating mode and the feedback signal from the switch to the controller during a feedback operating mode.

Abstract: A rotary atomizer (20) includes a manifold assembly (22) adapted to be attached to a mechanism for moving the atomizer and an air bearing turbine motor housing assembly (21) releasably secured to the manifold assembly. Sources of pressured fluid for actuating the atomizer and coating fluid are connected to the manifold (29) which has fittings (32, 33, 34, 35, 36) for releasably sealing to apertures (42) in the rear cover (43) of the housing assembly. The opposite end of the housing includes a shaping air cap (24) and a shaping air ring (25) which cooperate to define an annulus for discharging a thin ring of shaping air over the peripheral edge of an atomizer bell (26) to direct fluid particles toward a target. Exhaust air from the turbine motor (46) is vented to the inside of the housing and directed to a chamber (79) behind the atomizer bell to aid in directing the fluid particles.
