  • CAPACITIVE SENSING APPARATUS AND METHOD FOR FAUCETS
    Publication number: 20100108165
    Abstract: A fluid delivery apparatus includes a spout (12) located adjacent a sink basin (16). A fluid supply conduit (14) is supported by the spout (12). Capacitive sensors (29) and (41) are provided on the spout (12) and sink basin (16), respectively. A controller (26) is coupled to the capacitive sensors (29, 41) to control the amount of fluid supplied to the fluid supply conduit (14) based on outputs from the capacitive sensors (29, 41).

  • Compensation circuit for an automotive ignition sensing system
    Patent number: 6392315
    Abstract: In a vehicle having an engine and an ignition system, a sensing circuit is provided for sensing the ignition voltage and providing this sensed signal to various operating modules of the vehicle. The sensing circuit includes a diode/resistor filter that provides a filtered voltage signal at a first output node. A compensation circuit is provided that compensates voltage errors introduced by the filter circuit. The compensation circuit includes a second diode that has substantially identical electrical performance characteristics as the first diode, and that is preferably mounted on a common substrate. A voltage signal at a second output node between the second diode and the filter circuit is indicative of the voltage drop across the second diode, which is further representative of the voltage error introduced by the filter circuit. In one embodiment, the operating module receiving the ignition voltage signal is configured to receive voltage signals at the first and second output nodes.
