Abstract: A closure assembly includes a housing, a sensor, a door, and a primary actuator. The sensor is disposed within the housing. The door is supported by the housing and is movable between a closed position and an open position. The sensor is exposed when the door is in the open position. The primary actuator is operable to (i) apply a first force on the door to move the door from the closed position to the open position and (ii) apply a second force on the door to move the door from the closed position to the open position when the first force does not move the door into the open position.

Abstract: A slack adjuster for rotating an input shaft of a braking system includes a housing having an aperture defining a first axis. The slack adjuster also includes an output member positioned within the aperture. The output member is engageable with the input shaft for rotation therewith about a second axis parallel with and offset from the first axis. The slack adjuster also includes an incremental adjustment mechanism operable to impart cycloidal motion to the output member relative to the housing.

Abstract: A tire inflation apparatus includes a housing coupled for co-rotation with a vehicle wheel, which includes a rim and a tire. The apparatus also includes a pendulum coupled to the housing for relative rotation therewith, a mechanically actuated pump coupled to the housing and operated in response to relative rotation between the housing and the pendulum, a valve positioned downstream of the pump and movable between a closed position in which pressurized air generated by the pump is prevented from being transferred to an air chamber between the rim and the tire, and an open position in which the pressurized air may be transferred to the air chamber, an electrically powered actuator coupled to the valve for moving the valve to at least one of the open and closed positions, and a generator operable to convert rotational kinetic energy of the wheel to electrical energy to power the actuator.

Abstract: A method of thermal management includes positioning a first workpiece and a second workpiece in at least one tool having internal cavities, passing a fluid into at least one of the internal cavities to cool portions of the first and second workpieces, welding the first workpiece and the second workpiece in the at least one tool by resistance heating to form a joined workpiece, controlling a rate of cooling of the joined workpiece to slow a rate of cooling through at least one of a resistive heat element or welding electrode of the at least one tool.

Abstract: A method of heat treating an engine component includes connecting a disk having a plurality of titanium components to a fixture, positioning one of the titanium components into an induction coil loop, providing an alternating current to the induction coil loop, heat treating the titanium component positioned in the induction coil loop and, monitoring a temperature of the heat treating.
