Abstract: A suspension system includes a first and second mass and an actuator connected with the first mass and with the second mass and configured to influence a relative movement between the first mass and the second mass. The actuator includes a tube, and a magnetic assembly disposed in the tube. The actuator is configured to generate a force between the magnetic assembly and the tube as a result of the relative movement between the two. A motor is configured to rotate the magnetic assembly relative to the tube to vary the force in a velocity-dependent relationship. The actuator may generate forces to resist or assist motion between the first and second masses.

Abstract: Vehicular radiators and other heat exchangers containing carbon nanotubes (CNTs) are provided, as are methods for manufacturing nanotube heat exchangers. In one embodiment, the nanotube heat exchanger includes a coolant flow passage, an airflow path, a heat exchanger core bounding at least a portion of the coolant flow passage and the airflow path. The heat exchanger core contains a plurality of CNTs configured to enhance heat transfer from a coolant conducted through the coolant flow passage to airflow directed along the airflow path during operation of the nanotube heat exchanger. The CNTs can be, for example, single walled CNTs or other CNTs incorporated into one or more regions of the heat exchanger core by applying a nanotube coating to selected surfaces of the heat exchanger core or by producing the heat exchanger core to include one or more sintered, CNT-containing components.
