  • Patent number: 4450554
    Abstract: The asynchronous integrated voice and data communication system includes a continuously variable slope delta encoder and a continuously variable slope delta decoder to convert voice signals to coded signals and vice versa. A packetizer and a depacketizer are employed with each data and voice user to enable each of the plurality of data and voice users to have random access to a fiber optic transmission medium enabling each of the plurality of data and voice users to receive transmissions from all others of the plurality of users. A microcomputer is coupled to each of the voice and data users and the associated packetizer and depacketizer to enable any one of the plurality of data and voice users to establish communication with any other selected one of the plurality of data and voice users.

  • Patent number: 4419752
    Abstract: A circuit for transmitting in opposite directions two pulse-shaped signals via one connecting terminal(K) of a semiconductor body. When one signal is transmitted the signal path for the other signal is inhibited, which is accomplished by means of switching means (1, 2, 3, 4). A possible use of said circuit is one in which, via the same connecting terminal, a synchronizing signal for synchronizing the field deflection in a television receiver is first applied to the semiconductor body and a blanking pulse is produced from said body thereafter.
