  • Patent number: 4071910
    Abstract: A video terminal system having a plurality of distinct output devices providing humanly perceivable, alphanumeric information is disclosed. The video terminal processes and transfers the binary representations of each alphanumeric character to a character generator. A dot matrix corresponding to the character is provided by the character generator and is time-multiplexed so as to be time-shared by each of the output devices without the requirement for specialized circuitry and with minimal time degradation. The distinct output devices may be video displays and hard copy printers which display alphanumeric characters for a complete line, the video display devices receiving each complete line of characters in a predetermined time period and the printer devices receiving a slice of each character for a line upon request.

  • Patent number: 3983451
    Abstract: In a video terminal system wherein a number of characters are to be displayed on each forward horizontal scan, a scan control circuit is utilized to synchronize the displaying of characters with the scanning of the cathode ray tube. Both the scan control circuit and the displaying characters are tied to a timing chain. Since the displaying of characters occurs at a fixed predetermined time in the timing chain, the scan control circuit is required to control the movement of the scan such that the phase of the scan is regulated in time. The scan control circuit accomplishes synchronization by a self-regulating feedback circuit which controls the magnitude of the base drive to a power transistor. Since the storage time of a power transistor is proportional to the magnitude of the base drive current to the power transistor, a simplified circuit results which accurately places the characters at a fixed position.
