Abstract: An inductive coil is disclosed comprising a bobbin and a coil encircling the bobbin. The coil encircling the bobbin defines at least one layer of coil extending over a first portion of the bobbin. At least one other layer of the coil extends over less than the first portion of the bobbin. A method of constructing a coil sensor including a bobbin comprises beginning at a first location on the bobbin, encircling the bobbin with a coil defining thereby at least one layer of the coil, the at least one layer extending over a first portion of the bobbin; wherein at least one other layer of the coil extends over a second portion of the bobbin less than the first portion of the bobbin.

Abstract: An electronically actuated, air control valve regulates the flow of combustion air to an internal combustion engine. The valve includes an air passage having a throttle valve rotatable therein between a first, minimum air flow position and a second, maximum air flow position. Between the minimum and the maximum air flow positions is a default air flow position for operation of the engine during actuator inoperativeness. A biasing member has a first end operable to impart a force on the valve member in the direction of the default air flow position when the valve member in operable between the minimum air flow position and the default position. Likewise, the biasing member has a second end operable to impart a force on the valve member in the direction of the default air flow position when the valve member is operated in the range between the default air flow position and the maximum air flow position.

Abstract: A remote control lever module comprising a shaft rotatably mounted on a support. A friction pad has a pair or surfaces each of which frictionally resists rotation of the shaft with respect to the support and permits relative rotation between the shafts and the support. A bearing assembly is loosely fit about the shaft to assure that the shaft may rotate in the support.

Abstract: A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.

Abstract: A pair of coupling elements connected between an electric stepper motor and an engine throttle are selectively engaged and disengaged by a lever mechanism which effects a relative movement between the coupling elements in response to a mechanical input from a solenoid actuator. The lever mechanism includes integral elements for calibrating the relative movement between the coupling elements for a given mechanical input from the solenoid actuator so as to compensate for manufacturing and assembly tolerances of the various components.

Abstract: A low tire pressure sensor for emitting a magnetic signal when the tire pressure reaches a low limit pressure includes a signal device having a magnet movable from a storage position to an actuated position by tire pressure applied to the magnet from an air switch. The air switch includes a bellows charged to a reference pressure and exposed to tire pressure for moving in response to tire pressure changes, and a three-way valve operated by the bellows for venting the signal device to atmospheric pressure when the tire pressure is normal and for closing the vent and applying tire pressure to the signal device to actuate it when the pressure drops below a preset low pressure.

Abstract: An air switch responsive to low tire pressure for emitting a pulse of air when a critical low tire pressure is achieved comprises a housing having a chamber ported to the internal tire pressure and a bellows within the chamber filled to a reference pressure. A passageway connecting the chamber to an outlet port is closed by a spring biased poppet valve. A pin on the moving end of the bellows is arranged to extend through the passageway to abut the poppet valve so that when low tire pressure causes bellows expansion, the pin will unseat the poppet valve to allow air pressure to escape from the tire through the outlet port. A second valve surrounding the stem on the bellows engages the chamber end of the passageway to close the same whenever the tire pressure reaches a second critical low pressure to stop the airflow through the outlet port.
