Photosensitive sound generator

Claim 1

A self-contained photosensitive sound generator for use as an aid to behavior modification programs meeting the need to eliminate habitual and compulsive over-consumption of food stored in a darkened enclosure, such as a refrigerator or food storage container, comprising: (a) a housing adapted to contain a photosensitive cell, a sound transducer and an energy source for said cell and transducer; (b) a sound transducer in said housing; (c) a photoelectric cell in electrical communication to said energy source responsive to light when said enclosure is opened for the purpose of taking food, said photoelectric cell immediately energizing said sound transducer when activated by light to thereby cause a low audible signal alerting the person opening the enclosure to light that the opening behavior is to be stopped; (d) an energy source in said housing; (e) moisture protecting means surrounding said housing to protect said cell, said sound transducer and said energy source from moisture and cold temperature; and an optical aperture in said housing located directly in front of said photosensitive cell which permits and directs the light entering the enclosure against said cell to energize the same.
