    摘要： A closed-loop LED drive circuit includes at least one LED, a voltage source, and a voltage regulator connected to the voltage source to provide a regulated voltage output. A one-time-programmable voltage source is connected to an output of the voltage regulator and a current controlled drive circuit is connected to the one-time-programmable voltage source for providing a drive current to the at least one LED in response to an output from the one-time-programmable voltage source. An end of line tester monitors the light intensity of the LED device and provides a signal indicative thereof to said one-time-programmable voltage source. The one-time-programmable voltage source stores the light intensity value and uses the light intensity value to control its output voltage to the current control drive circuit.

    摘要： A guide pin, for a disc brake assembly, comprises a head portion and a stem. The stem extends from the head portion along an axis and has a circular cross section, a first stem portion, and a second stem portion. The first stem portion is adjacent a tip of the stem. The second stem portion is between the first portion and the head portion. The first stem portion has a first radius from the axis and the second stem portion has a second radius from the axis. The second radius is less than the first radius. A surface is on the first and second stem portions. A distance is from a plane to the surface. The plane is parallel to the surface and the axis is in the plane. The distance is less than the second radius.

    摘要： A ground loss detection circuit identifies a faulty ground connection in a vehicle electrical system including a pair of redundant ground lines connected between a vehicle battery/chassis ground and an electronic control unit (ECU). In particular, a first ground line is connected between the battery/chassis ground and a first ECU ground connection, while a second ground line is connected between the battery/chassis ground location and a second ECU ground connection. The ECU includes a common ground associated with selected electronic components included in the ECU. A first shunt component is connected between the first ECU ground connection and the common ground, and a second shunt component is connected between the second ECU ground connection and the common ground. The currents through the first and second shunt components are monitored to identify a current imbalance to detect a faulty ground connection in one of the first and second ground lines.
