Abstract: An elastomeric seal (20), such as a shaft seal for automotive vehicle applications, includes an elastomeric compound (22) chemically coupled to a metal sealing ring (24) and is formed without an oven post curing step. The elastomeric seal (20) provides exceptional physical properties, similar to those of elastomeric seals of the prior art formed with an oven post curing step. The elastomeric seal (20) has an elastic modulus of 6.0 MPa to 13.0 MPa and a tensile strength of 11.1 MPa to 14.8 MPa. The elastomeric compound (22) includes 52.0 to 68.0 wt. % fluoroelastomer, 20.0 to 35.0 wt. % calcium silicate, and 5.0 to 15.0 wt. % diatomite. The elastomeric compound (22) is fully cured and chemically coupled to the metal sealing ring (24) during the compression or injection molding step, and thus an oven post curing step is not required.

Abstract: A piston for an automatic transmission includes a cylindrical portion formed of a steel material and an elastomer bonded thereto. The elastomer includes an ethylene-acrylic polymer, a filler, and a hexamethylene diamine curing agent. The elastomer is compression or injection molded to the metal cylindrical portion. During the molding step, the elastomer is cured and achieves a cross-link density, strength, and other physical properties sufficient for use in an automatic transmission. Thus, the piston is formed without a post curing step. The piston provides a lower wear rate and a higher life expectancy than pistons formed with a post curing step.

Abstract: An illumination control circuit allows a user to set a desired brightness level and maintains the desired brightness level over temperature and life of a light source. The illumination control circuit uses a dual feedback loop with both optical and thermal feedbacks. The optical feedback loop controls power to the light source during normal operations. The thermal feedback loop overrides the optical feedback loop when the temperature of the light source becomes excessive.
