Abstract: A rotary position sensor is disclosed having a magnetic element having a cavity therein. A flux concentrator is arranged to substantially surround the magnetic element, and a magnetic field sensor located within the cavity. The magnetic element may have rectilinear portions.

Abstract: A switch is disclosed having first and second switch elements each configured to provide power to a sensor when in one state and configured to switch to a second state and provide positional information, for example. The sensor configured to effect the first and second switches to switch to the second state and to switch back to the one state, the first and second switch elements configured to switch alternately and in a complementary way.

Abstract: A throttle control device for transmitting signals to an electronic fuel control system for a vehicle engine is provided that includes an electromagnetic field generator and first and second electromagnetic field sensors positioned proximal to electromagnetic field. The electromagnetic field and the first and second sensors being manipulatable relative to each other, and the sensors being responsive to the relative manipulation. The sensors configured to independently transmit signals representative of said relative manipulation.

Abstract: Embodiments of the present invention provide a pedal force augmentation device. Other embodiments may be described and claimed.

Abstract: A control lever assembly in the form of a foot pedal includes a pedal arm pivotally mounted on a shaft supported on a base or bracket, and a helical spring for returning the arm to a home position. Lateral displacement of the spring during loading thereof is prevented through the use of either a mechanical stop engaging one side of the spring or eccentric mounting of the spring on relative to shaft.

Abstract: A low profile electronic throttle pedal assembly for vehicles includes a base plate mounted on the floor of the vehicle and a throttle treadle pivotally mounted on the base plate. The treadle includes a lower lever arm portion extending through the base plate into a space beneath the vehicle floor. A throttle position sensor as well as the drive mechanism connecting lever arm with the sensor are both carried on the bottom side of the plate, beneath the vehicle floor. Treadle return springs pass through the plate and are seated beneath the vehicle floor.

Abstract: A device for providing a pedal operator with tactile indication that a pedal (32) has been depressed to a preselected position includes a cup-like housing (50), a ring-shaped magnet (52) mounted within the housing (50) and a displaceable member (54) provided with a pin (56) engageable by the pedal (32). The pin (56) extends through aligned openings in the magnet (52) and housing (50) and mounts the displaceable member (54) for linear sliding movement on the housing (50). Depression of the pedal (32) to the preselected position results in shifting of the displaceable member (54) away from the influence of the magnet (52) to provide the operator with a snap-like tactile indication of pedal position. The cup (50), magnet (52) and displaceable member (54) are each made of unitary, one-piece construction and of simple, circular geometry.
