  • Positional transducer
    Patent number: 4544803
    Abstract: A positional transducer includes a nonconductive plate having four ferrite tube inductors mounted at preselected locations in the plate. Two interconnected permanent magnets are mounted on either side of the plate with opposite poles facing the plate for magnetic interaction. Manual movement of the permanent magnets varies the impedance of the inductors to indicate the relative position of the magnets to the inductors.

  • Method of making thin film thermistor
    Patent number: 3966578
    Abstract: A thin film thermistor and a method of making such a thermistor in which a composition of lead telluride plus 5% cerium is sputtered on to a polyimide film after which electrodes are deposited thereon with the width of lead telluride composition remaining uncovered being controlled to thereby control the thermistor characteristics.
