Even though the detector operated only during a few months in the summer of 1997, it was largely successful.

Its detector operated on the principle of electron-positron pair production from high energy photons interacting in the detector.

During the repairs, the detectors were still operating and able to look at cosmic ray events.

The detector operated with close to 100% efficiency and provided performance characteristics very close to its design values.

The ultrasonic detector operates by the transmitter emitting an ultrasonic signal into the area to be protected.

Most infrared detectors operate at very low temperatures so that the heat of the detector does not interfere with its readings.

Acquired by Det-tronics in 1992, the detector operated in the 3.4 μm region with a powerful incandescent source and a mechanical chopper.

The project was delayed by funding problems and leaks in the water tank, but by the end of summer 1982 the detector was operating at full capacity.

Their thermalsignature detectors can't operate over too great a range or they'd mistake large mammal-analogues for us.

The vest contains detectors that record hits and misses from laser operated weapons.
