Combination marker light and infrared interrogation device

A marker and interrogation response device, comprising:

• an enclosure;
• a plurality of emitters within the enclosure;
• means for activating a subset of the plurality of emitters to emit a first light, the first light passing out of the enclosure;
• at least one detector within the enclosure, the at least one detector for receiving interrogation signals that pass into the enclosure;
• a circuit within the enclosure detects at least one of the interrogation signals and, responsive to detecting the at least one of the interrogation signals, the circuit causes at least one of the emitters to emit light, the light passing out of the enclosure;
• and an operating status switch in electrical communication with the circuit, whereby upon activation of the operating status switch, the circuit causes one or more vibration motors to vibrate in a pattern, the pattern depending upon an operational state of the marker and interrogation response device.

A marker and interrogation response device, comprising in combination:

• an enclosure;
• a circuit within the enclosure;
• a first switch interfaced to the enclosure and electrically interfaced to the circuit, the first switch for selectively choosing a function;
• a second switch interfaced to the enclosure and electrically interfaced to the circuit, the second switch for selectively choosing an operating mode;
• at least one light emitting diode mounted within the enclosure and electrically interfaced to the circuit;
• at least one photo detector mounted within the enclosure and electrically interfaced to the circuit;
• a operating mode status switch interfaced to the enclosure and electrically interfaced to the circuit, the operating mode status switch for determining the status of the marker and interrogation response device;
• a vibration device located at a location selected from the group consisting of a location within the enclosure and a location external to the enclosure;
• wherein the circuit determines a mode based upon signals from the first switch and the second switch and, based upon the mode, the circuit selectively provides electrical current to one or more of the at least one light emitting diode such that the one or more of the at least one light emitting diode emit light that passes through at least a portion of the enclosure, and upon the circuit detecting an interrogation signal from any of the at least one photo detector, the circuit provides electrical current to at least one of the at least one light emitting diode to respond to the interrogation signal, thereby the at least one of the at least one light emitting diode emits the light which passes through the portion of the enclosure responsive to the circuit detecting the interrogation signal;
• wherein responsive to the circuit detecting the interrogation signal, the circuit provides electrical current to the vibration device, thereby causing the vibration device to vibrate.
