  • Radiation source detector and tracker control having a shade pole and radiation responsive surface in the shape of narrow bands
    Patent number: 5317145
    Abstract: A tracker controller system in which a pair of photo-resistive cadmium sulfide sensors mounted in the shadow of a shade pole generate a voltage signal proportional to their resistive values which signal is delivered to a comparator circuit that causes a tracker driver to operate when the voltage signal falls outside of a voltage window established by the comparator circuit.
