DISPOSIZIONE CIRCUITALE PER LA SINCRONIZZAZIONE DELL'ANGOLO DI ROTAZIONE DELLE STECCHE DI UNA PLURALITA' DI PERSIANE IN PARTICOLARE DI TENDE ALLA VENEZIANA AZIONATE SIMULTANEAMENTE DA MOTORI ELETTRICI

摘要

This invention relates to a circuit arrangement and the associated mechanism for slaving the angles of rotation of the slats of a plurality of centrally controlled sun or window blinds. The driving motor of each blind is provided with current via a corresponding operational amplifier and related circuit. The motor operates the slats to achieve balance between an input control voltage and a voltage depending on the angular position of the slats. An automatic version in which the control voltage is generated by a photoelectric sensor and several circuit variations are shown.
