摘要： The self-contained diagnostic system is provided for a stroboscopic light circuit. The diagnostic system includes a plurality of signal lights, preferably LEDs, connected at various locations in the circuit to provide a visual indication of the faulty portion of the circuit in the event that the circuit does not operate properly. The system provides a quick and easy method for determining the location of a malfunction of a stroboscopic light without the necessity of replacing the entire light system or the use of diagnostic equipment.

摘要： A light is dimmed by pulsing it at a selected duty cycle. By pulsing, the light can be dimmed without being turned off completely which reduces wear on the filament. The circuit is designed for flashing a pair of ditch lights on a railroad locomotive. The lights are alternately illuminated at full voltage and dimmed by pulsing. The flashing sequence can be activated when the locomotive is travelling below a selected speed or when the horn is sounded. The duration of the flashing sequence is controlled by a timer. The pulsing circuit can be used to effectively reduce a voltage without voltage dropping resistors.

摘要： An improved digital servo indicator of the continuous null-balance potentiometric type is disclosed which includes a microcomputer to provide a digital readout of the measured results in the desired engineering unit, or to use the readout in further calculations as desired. The indicator includes a digital-to-analog conversion means using a cascading series of circuits each having a precision resistance element and a pair of MOSFETs for selectively connecting a constant reference voltage to the output through the resistance element to produce the desired analog output.

摘要： The present invention relates to an improved connector for joining two tuar members together. The connector is formed by a plurality of longitudinally extending fingers extending from an end of one of the tubular members and at least one locking groove in the other of the tubular members for receiving the fingers. The connector further includes a circumferentially extending wire member which is received in a notch in a head portion of each of the plurality of fingers. The wire member is preferably formed from a shape memory alloy and has an original circumference less than the circumference of a circle formed by the notches in the head portions of the fingers. The connector includes apertures through which electric wires may be connected to the shape memory alloy ring member so as to cause the shape memory alloy ring member to return to its original shape and allow release of the joint connection.
