Pneumatic are mainly for a normal speed cadence while hydraulic control units are used for more moderate to higher cadences. For example, one portion of the sound would sense large, stationary objects while another could pick up smaller, fast-moving obstacles. The liner is a soft interface that the patient wears over the skin. As it searches for small preylike a nearby June bugit listens for subtle changes in the higher pitches of the echoes.
