System, Method, and Apparatus for Detecting IR Radiation in a Marker System

A marker system comprising:

• an enclosure;
• a controller in the enclosure;
• a radio frequency transmitter within the enclosure, the radio frequency transmitter is operatively coupled to the controller;
• a helmet-mounted power source provides electrical power to the controller;
• a wireless feedback module having a power source, a signaling device and a radio frequency receiver, the signaling device interfaced to the radio frequency receiver;
• a first infrared detector is electrically interfaced to the controller and aimed to receive infrared light through the enclosure;
• a second infrared detector is electrically interfaced to the controller and aimed to receive the infrared light through the enclosure, aimed in a different direction than the first infrared detector;
• when the controller receives an electrical signal from any of the first infrared detector and/or the second infrared detector, the controller determines a relative direction from which the infrared light originated, and the controller transmits a radio frequency signal using the radio frequency transmitter, the radio frequency signal includes the relative direction;
• and
• when the radio frequency receiver in the wireless feedback module receives the radio frequency signal, the wireless feedback module emits a signal using the signaling device, the signal is encoded with the relative direction.

A method of signaling regarding a reception of an infrared signal:

• within an enclosure, aiming a first infrared detector and a second infrared detector to receive infrared light through the enclosure whereas the first infrared detector is aimed in a different direction than the first infrared detector for differentiating a direction from which the infrared light originates;
• when receiving the infrared light from the first infrared detector and/or from the second infrared detector, determining a relative direction from the first infrared detector and the second infrared detector and transmitting a radio frequency signal to alert of the reception of the infrared light, the radio frequency signal including the relative direction;
• and
• within a wireless feedback module, when receiving the radio frequency signal, operating a signaling device to alert a wearer regarding the infrared light and the direction.
