Abstract: A damping device for use with a rotatably-mounted steering shaft. The damping device comprises a magnetorheological material that can be embedded in an open-network carrier and is directly or indirectly in contact with the steering shaft, a coil arranged in effective proximity to the magnetorheological material, and a body indirectly in contact with the steering shaft through the magnetorheological material, which does not rotate with the steering shaft. A voltage can be applied the coil to activate the magnetorheological material, increasing a viscosity of the magnetorheological material to inhibit relative rotation of the steering shaft and the body.

Abstract: An electrically insulated conductor for carrying signals or current includes a solid or stranded copper core of various geometries with only a single electrically insulating and thermally conductive layer of anodized aluminum (aluminum oxide). The device is made by forming a uniform thickness thin sheet or foil of aluminum to envelop the copper or copper alloy core. The aluminum has its outer surface partially anodized either before or after forming to the core in an electrolytic process to form a single layer of aluminum oxide.

Abstract: A reflective clear coat composition. In at least one embodiment, the composition includes a clear coat composition including a polymeric binder comprised of one or more resins and reflective flakes having a reflectivity of at least 30% in at least a portion of the near infrared radiation (NIR) region of the solar spectrum and a reflectivity of 29% or less in at least a portion of the visible region of the solar radiation spectrum. The reflective clear coat composition can be cured onto an exterior cured paint surface of an automotive vehicle. The resulting cured clear coat composition may reduce the temperature generated within a vehicle passenger cabin while exposed to solar radiation.

Abstract: A method of manufacturing electric machines comprised of geometrically patterned arrays of permanent magnets, soft magnetic materials, and electrical conductors deposited by kinetic spraying methods directly atop a carrier. The magnets and planar coils of the present invention may be integrally formed atop carriers to form electrical machines such as motors, generators, alternators, solenoids, and actuators. The manufacturing techniques used in this invention may produce highly defined articles that do not require additional shaping or attaching steps. Very high-purity permanent and soft magnetic materials, and conductors with low oxidation are produced.

Abstract: An electromagnetic coupling device includes a rotating member having an embedded coil positioned to provide a magnetic flux path through the rotating member while substantially eliminating at least one air gap to improve efficiency. At least one bearing or bushing assembly disposed between the rotating member and a second member includes an electrically conductive lubricant to supply electrical current through the assembly and lubricant to the embedded coil during actuation of the device. A method of making an electromagnetic coupling device includes embedding a coil within a rotating member such that the rotating member contacts substantially the entire outer surface of the coil to provide an efficient magnetic flux path and thermal conductivity for heat dissipation through the rotating member and connecting the embedded coil to at least one conductive bearing assembly having conductive lubrication grease.
