Abstract: A fast heat rise resistor comprising a substrate, a foil bridge on the surface of the substrate, the foil bridge having an elevated portion and a contact portion, the elevated portion above the substrate, the contact portion in contact with the substrate, a conductive layer attached to the contact portion of said foil bridge. The activation energy and/or response time is reduced as the foil bridge is suspended over the substrate. Another aspect of the invention include a method of manufacturing the foil bridge and application to autoignition vehicle airbags.

Abstract: An improved surface mount resistor and method for making the same includes a body comprised of an elongated strip of electrically resistive material and a resistor terminal formed at each end of the resistive material. The resistive material is machined with a laser beam to create a current path having a desired resistance. The pattern cut is determined by partitioning the resistive material into a plurality of squares forming a current path through the resistive material with the correct resistivity. The resistive material is cut primarily with axial cuts so that the beam strength of the resistive material is maintained.

Abstract: A method of conformally coating a capacitor with an epoxy layer of the present invention is used to coat the capacitor using fluidized bed techniques. The method includes the use of a chiller bar which is placed against the cathode surface of a capacitor slug which has been heated to 150.degree. C. The capacitor slug and chiller bar are then dipped into the fluidized bed of epoxy powder. The epoxy powder will melt to the capacitor slug on all surfaces except the surface in contact with the chiller bar. After removing the capacitor slug and chiller bar from the fluidized bed and separating the chiller bar from the capacitor, the capacitor will be coated with a layer of epoxy coating on all surfaces except the cathode surface.
