Radar data exchange was only done at a limited scale, one of the reasons being that the sensors were using proprietary, incompatible formats.

The sensor uses highly calibrated internal electronics to measure the response of the device to the Earth's magnetic field.

This unique sensor uses the principle of magnetic induction.

Those sensors used heat emissions to locate and identify objects, just as an ordinary telescope uses light.

The sensor uses four lenses and 368 cell phone cameras, 5 megapixels each.

One sensor uses reflected sound waves (ultrasound) to keep track of your baby's heart rate.

Company officials said the watch would probably cost $400 to $500 and the disposable sensors used with it, $4 to $5 each.

This sensor uses a hot film-grid instead of a hot wire.

To achieve those abilities, the machine would need sensors to observe its surroundings and then use the best mode of locomotion.

Most current sensors for chemical agents use one of two techniques.
