Abstract

MEDIDOR DE ELETRICIDADE. Medidor para medição da utilização da eletricidade para uma dada carga que inclui um compartimento e duas fontes de luz dispostas no compartimento e configuradas para liberarem luz a uma freq³ência pré-determinada. Dois receptores de luz são dispostos no compartimento de modo que o trajeto da luz seja definido entre cada fonte de luz e seu respectivo receptor de luz. Cada receptor de luz é configurado para receber a luz de sua fonte de luz e para liberar um sinal em resposta a mesma. Um membro giratório apresenta-se disposto no compartimento nos trajetos da luz e apresenta-se de forma giratória em resposta a utilização da eletricidade. O membro apresenta uma primeira porção e uma segunda porção. A primeira porção transmite luz incidente enquanto que a segunda porção bloqueida a luz. A primeira e a segunda porções são definidas no membro de modo que o membro modula a luz conforme esta gire. Um circuito de filtragem em comunicação com o receptor de luz é configurado para receber o sinal de saída a partir do receptor de luz e para detectar a partir do mesmo modulação da luz pelo membro giratório.
