Abstract: An air spring with damping characteristics for a suspension assembly of a heavy-duty vehicle includes a bellows and a piston. The bellows includes a bellows chamber. The bellows is attached to a main member of the heavy-duty vehicle and to the piston. The piston includes an open bottom that is sealingly closed by a disc attached to the open bottom. The piston and the disc define a piston chamber. The piston is mounted on the suspension assembly of the heavy-duty vehicle. The bellows chamber and the piston chamber are in fluid communication with each other via at least one opening, wherein airflow between the bellows chamber and the piston chamber provides damping to the suspension assembly of the heavy-duty vehicle.

Abstract: A vehicle bumper system is shown to include a vehicle bumper component, a main electrical connector integrated with the vehicle bumper component, a second electrical connector integrated with the vehicle bumper component, and an electrical communication path integrated with the vehicle bumper component. The electrical communication path extends between the first electrical connector and the second electrical connector. The vehicle bumper component is designed to permit mounting of an electrically controlled device at a mounting area. The second electrical connector is at or in close proximity to the mounting area to permit the electrically controlled device to electrically couple therewith when it is mounted at the mounting area of said vehicle bumper component. Another electrical communication path electrically couples the second electrical connector with bumper mounting holes used to permit mounting of the bumper component with a vehicle chassis/frame.
