Abstract: An end cap for a fuel pump provides suppression of radio frequency noise generated by the motor of the pump. The end cap includes radio frequency suppression circuitry disposed therewithin and is configured so as to be a direct replacement for conventionally utilized end caps.

Abstract: A radio frequency suppression device is adapted to provide a current path having no solder joints disposed in series therewith as well as no components prone to fail in an "open" mode. The R.F. suppression device is adapted to continue to provide power to critical systems such as an automotive fuel pump, even in the event of failure of the R.F. suppression circuit.

Abstract: A pressure sensitive signal generator assembly includes a piezoelectric subassembly, a flexible electroluminescent panel and a transparent cover element so arranged that the cover element is in force-transmitting relation with the piezoelectric subassembly and the electroluminescent panel is interposed therebetween. The piezoelectric subassembly includes a substantially planar, rigid yet manually flexible, substrate member; one or typically several, discrete piezoelectric elements, preferably crystals; and electrical conductors connected to the opposite surfaces of respective piezoelectric elements for developing a voltage therebetween in response to deformation of the piezoelectric element. An applique sheet, interposed between the cover and the electroluminescent panel contains indicia for identifying the respective piezoelectric elements. The cover element may be an integral portion of a plastic housing in which the signal generator assembly is housed.
