Abstract: An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentic knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

A BTSI system for a motor vehicle includes a shifter solenoid with a solenoid body that mounts to the vehicle body, and a solenoid armature that is movably attached to the solenoid body to transition back-and-forth between locked and unlocked positions. The shifter solenoid is selectively operable via a brake control module to move the solenoid armature between the locked and unlocked positions to thereby block and unblock movement of a gear shifter from the park position, respectively. A position switch mounts to the vehicle body adjacent the shifter solenoid and detects the vehicle transmission being in a park mode. The position switch selectively mechanically engages with the shifter solenoid such that the solenoid armature, upon moving to the locked position, pushes closed the position switch.

Abstract: Systems and apparatus for reliably sealing a surgical device are disclosed herein. Specifically, a surgical device including a drive shaft tube that is coupled to a drive shaft is disclosed. Because the drive shaft tube is coupled to the drive shaft, the drive shaft tube rotates at the same rotational speed as the drive shaft, which is less than the rotational speed of a cannulated motor shaft. The drive shaft tube can extend through the cannulated motor shaft. In addition, a sealing member can be provided to seal between the drive shaft tube (which rotates slowly) and the motor instead of between the motor shaft (which rotates more quickly) and the motor. The sealing member can be provided in a gap defined between an outer surface of a portion of the drive shaft tube extending beyond the cannulated motor shaft and the motor.
