Medical probes and other devices also rely on materials of this kind.

All such devices, of course, rely upon the muscle power and endurance of the operator.

Baird's first devices relied upon the Nipkow disk and thus became known as the mechanical television.

Collecting devices rely on their position to most effectively capture sunlight.

At this point, the device relied upon the friction force between the cards to achieve some kind of randomness.

The problem is that many devices are quite a few years old, and rely on very precise positioning.

His device relied on conduction in the ground, a type of radio transmission.

Rather than closed architectures, these devices rely on standard interfaces.

Those devices rely on satellites, rather than a compass, to provide directions.

The device relies on compounds that act as sensors, changing color in the presence of specific chemicals.
