摘要： A tester for in situ testing of a plurality of circuit breakers having a range of rated currents and multiple trip functions, includes a plurality of power resistors of known impedance, an electronic switch associated with each power resistor connecting the resistor in series with the load terminal of the circuit breaker under test, and a controller that turns on a number of the switches selected to collectively draw through the associated power resistors a test current that is a function of the rated current and sufficient to trip the circuit breaker within a selected time window. Turn on of the electronic switches is also controlled to generate a current waveform appropriate for the trip function being tested. In a self test mode, the value of each of the power resistors is verified as being within limits.

摘要： Arcing faults in an ac current are detected by apparatus which is responsive to a predetermined randomness in step increases in the current to eliminate false tripping caused by regularly occurring discontinuities produced by loads such as dimmers. A signal conditioner generates a bandwidth limited di/dt signal having pulses produced by the step increases in current. In one embodiment, a first tracking circuit tracks the envelope of the di/dt signal with a first time constant. A second tracking circuit also tracks the di/dt envelope, but with a second, shorter time constant. An arcing fault is indicated if the second tracking signal falls to a predetermined fraction of the fist tracking signal. This circuit may be used alone to detect arcing faults or to increase the sensitivity to arcing faults over dimmers of a circuit which responds to a time attenuated integrated valve of the pulses in the di/dt signal. In another embodiment, the di/dt envelope signal is subtracted from the magnitude of the pulses before they are applied to the time attenuated integrator, but with the subtraction time delayed to preclude attenuation of the first pulse.

摘要： The continuity of the coil of the actuating solenoid of an electric power switch is detected through utilization of a signaling device, such as a light emitting diode (LED) that monitors energization of a dc power supply fed from the source side of the coil. A circuit energized from the other side of the coil generates a dc voltage V2 that is applied to the gate electrode of an electronic switch shunting the LED. The voltage V2 is greater than the dc supply voltage to bias the electronic switch off so that the LED is illuminated when there is continuity through the coil. If the coil fails, V2 will be zero and the electronic switch is turned on to short circuit the LED to signal the failure of the coil.

摘要： A back-up proximity sensor for a vehicle is formed with an array of sensor pairs. Each sensor pair includes a lower passive infrared sensor (PIR) having a first field of view and an upper PIR having a second field of view. Each lower PIR and upper PIR is vertically mounted with respect to one another. The lower PIR and upper PIR of each sensor pair are angularly directed such that the respective fields of view intersect, thereby establishing a detection zone in a region behind a vehicle. The sensor pairs are arranged in a substantially adjacent, semicircular configuration to provide a continuous area of coverage behind a vehicle. A detection circuit receives output signals from each sensor pair and generates an output signal indicative of a warm body being detected by both the upper and lower sensors in a selected sensor pair, eliminating false alarms generated by warm bodies outside the region of the desired detection zone.

摘要： The present invention is directed to a centrifugal pump wherein voltage and current data are detected from voltage and current sensors in the pump motor. A power signal is then generated from the voltage and current data and spectrally analyzed to determine the low flow or cavitation in the pump. As such, unwanted operational conditions resulting from improper pump operation may be detected and a warning or maintenance flag provided without additional transducers and other instruments on the motor or pump.

摘要： A backup proximity sensor for a vehicle includes a first passive infrared sensor (PIR) and a second PIR vertically mounted with respect to one another on a pivotal support member. The first PIR and second PIR are angularly directed such that the respective fields of view converge, establishing a detection zone in a region behind a vehicle. A drive motor and scanning gear box are coupled to the pivotal support member and pivotally drive the first and second PIR in an oscillatory fashion about a predetermined arc. This establishes relative motion between the PIRs and a stationary warm body in the field of view of the two sensors, allowing the stationary body to be detected. A detection circuit receives output signals from the first PIR and second PIR and generates an output signal indicative of a warm body being detected by both the first and second PIRs. This eliminates false alarms generated by warm bodies outside the region of the desired detection zone.
