Abstract: A fire control assembly and a method are disclosed. The fire control assembly contains a pivotable shaft containing a first end and a second end, and a first selector member removably coupled with the first end of the pivotable shaft, wherein the first selector member is movable between a first position relative to the pivotable shaft and a second position relative to the pivotable shaft, wherein the first selector member is configured to rotate the pivotable shaft from a safe position to a firing position and back to the safe position when the first selector member is in the first position relative to the pivotable shaft, wherein the first selector member is configured to prevent the pivotable shaft from rotating into the firing position when the first selector member is in the second position relative to the pivotable shaft.

Abstract: A method and apparatus controls a recirculation position of a return vent in an HVAC system for a vehicle with a compressor driven by a start/stop engine. A partial recirculation position is set according to a basic recirculation strategy while the engine is operating. An auto stop event is entered at a time with the compressor operating. A full recirculation position is set during the stop event by an HVAC controller if a plurality of low fogging probability indicators are true. The low fogging probability indicators include a sensed ambient temperature being above a predetermined temperature, a sensed state of a windshield wiper being an off state, and a sensed sunload being above a predetermined sunload. The return vent is set at other than the full recirculation position by the HVAC controller according to the basic recirculation strategy if the low fogging probability indicators are not true.

Abstract: A vehicle air handling system includes an air conditioner having an inlet selectively opening to a source of fresh air or recirculated air from within the passenger compartment. A controller switches the source of inlet air to recirculated air under certain conditions in order to optimize system efficiency and component life.

Abstract: A method of automatically controlling the operating speed of a vehicular windshield wiping system based on an average rate of change in the value of a sensor signal indicative of the moisture on the windshield. The wiping system includes a motor for driving at least one wiper blade at a high speed and a low speed, and a sensor mounted to the windshield for monitoring a portion of the windshield wiped by the at least one wiper blade. The method includes determining an average rate of change in the sensor signal value over a predetermined period of time and operating the wiper system with the motor at the high speed based on the average rate of change in the sensor signal value. In one embodiment, the method includes wiper system is operated with the motor at the high speed based on the frequency with which the average rate of change in the sensor signal value drops below a first predetermined threshold.
