  • Patent number: 7318654
    Abstract: A headset with a light incorporated within is disclosed. A representative embodiment of the invention may be construed as an aviation-style headset that includes a first earcup and a second earcup each comprising active noise reduction (ANR) circuitry, a headband interconnecting the first earcup and the second earcup, and a boom microphone coupled to one of the first and second earcups. The headset also includes a rotating housing coupled to at least one of the earcups. A first light-emitting diode (LED) is mounted in the rotating housing. The rotating housing is rotated to point light from the LED in a desired direction. The headset also includes a switch mounted to one of the earcups for controlling the LED. The ANR circuitry is electrically coupled to at least the first LED to deliver power to the LED. Other systems and devices are also disclosed.

  • Patent number: 4510482
    Abstract: A resistor device comprises a first film of resistive material deposited on a dielectric substrate and having two terminal portions for connection to an electrical circuit, and a second film of resistive material deposited on the substrate in thermally-conductive contact with the first film and electrically isolated therefrom. The material of one of the films has a relatively high temperature coefficient of resistance, so that the resistance of that film can be utilized as an indication of the temperature of the other film.
