ABSTRACT:
A multi-modal proximity sensor system includes one or more individual sensor units which are two-stage dual ring contact units but are flexible enough to be made as a single stage unit by omitting a single ring contact and a connector resistor. When used in either mode, a probe when deflected by proximity to an object will set off a buzzer alarm as well as a light alarm upon touching a ring contact. In the preferred embodiment (i.e., the two-stage embodiment), as soon as the probe deflects beyond a first predetermined level, a first stage alarm is generated, and as the probe is deflected past a second level, a second stage alarm is generated, which constitutes an increase in volume of the audible signal, and brighter light in the visual signal. In addition, overall sensitivity is easily adjustable by the axial adjustment of the probe within the body of the indicator unit relative to the contact rings.
