  • Flashlight with forward looking sensing of thermal bodies
    Patent number: 5839821
    Abstract: A flashlight includes a light source and a detector for detecting emissions from the surroundings. Depending on the position of a switch, the output of the detector is channeled through either a speaker or a LED array. The speaker outputs a tone having a frequency dependent on the intensity of the electromagnetic emissions. The LED array illuminates a series of LED elements in a manner representative of the intensity of the electromagnetic emissions. In one embodiment, the flashlight incorporates infrared detectors for detecting infrared thermal emissions.
