ABSTRACT:
Fresnel lenses are incorporated into bear's paws of a child's toy teddy bear. The Fresnel lenses cover infrared detectors, and gather infrared energy and focus it onto the infrared sensors. The signal generated by the infrared sensors is passed to a detector timer assembly and then to a power control device. The detector assembly consists of a low-pass filter, a level comparator, a variable time-on timer, and a daylight override circuit. The power control device provides power to an outlet.
