Abstract: There is provided a hydraulic system for a vehicle. The hydraulic system has a hydraulic rotary actuator assembly rotationally coupled to a road wheel of the vehicle. The hydraulic rotary actuator assembly has a first operating mode, wherein a rotation of the road wheel causes the hydraulic rotary actuator assembly to pump a fluid from a fluid supply system.

The variable restrictor assembly controls a flow of the fluid flowing from the hydraulic rotary actuator assembly, to brake the rotation of the road wheel on a ground surface. The hydraulic system further has a variable restrictor controller coupled to the variable restrictor assembly. The variable restrictor controller controls the variable restrictor assembly, so as to enable a variation of a rate of braking of the road wheel on the ground surface.

Further, the method comprises dissipating any remaining electrical power of the electrical power, which is stored in the electrical power storage unit, when the panel is closed.

Abstract: A water heater system includes a tank having internal capacity no greater than 1 gallon, a water inlet, and a water outlet. A flow of water into the tank through the water inlet and out of the tank through the water outlet is a downstream water flow.

Abstract: A system and method for detecting and removing moisture in a vehicle such as a commercial aircraft is disclosed. Moisture detection sensors are mounted in areas of the vehicle which are inaccessible during use. The sensors output a signal when moisture is present in an adjacent area. Conduits are installed in the vehicle with a first end adjacent to an associated moisture detection sensors. A dry gas supply unit that is separate from the vehicle is coupled to a second end of each conduits to selectively supply dry gas thereto. The dry gas supply unit selectively supplies dry gas to the second end of each conduit when an associated moisture detection sensor outputs a signal indicating that moisture is present in the adjacent area. The moisture detection sensors are preferably passive and only output a signal upon receipt of an external interrogation signal from the dry gas supply unit controller.

Abstract: A taxi or other vehicle summoned by someone who needs a ride can be remotely controlled to announce its presence by the person who summoned the taxi or other vehicle. Using a cell phone, a user establishes a wireless communications link between his or her cell phone and a cell phone in the taxi or other vehicle. A second wireless link between the taxi-located cell phone and the vehicle's control bus enables commands to be sent to the vehicle's horn, lights and other annunciators from the user's cell phone. Images of the requesting user can also be sent to the taxi-located cell phone.
