Abstract

1535433 Remote control of receivers SABA SCHWARZWALDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOHNE GmbH 26 Nov 1976 [27 Nov 1975] 49527/76 Heading G1A [Also in Division H3] In a receiver apparatus 1 having an optoelectronic device 3 for receiving modulated light signals in the infrared region # 2 for remote control by a generator 4 and an opto-electronic device 2 for transmitting modulated light signals in a different infrared region # 1 for transmission of audio frequency information derived from the apparatus to a headphone 6, optical decoupling between the transmitter device 2 and the receiver device 3 is obtained by a filter 7 arranged in front of the receiver device 3 which filter is impermeable to light of the wavelength transmitted by the transmitter device 2 which conveys the audio frequency information. The light transmitters 2 and 4 include luminous diodes whose spectral range may for example lie at # 1 =750nm � 20nm and # 2 = 920nm � 20nm. Both the light receivers 3 and 5 include photo diodes.
