  • Method and apparatus for transmission of synchronization signals between microprocessors in video system
    Patent number: 4951142
    Abstract: In order to couple together vertical-frequency synchronization signals generated by a computer connected to an data transmission system, the synchronization signals are generated by counting the clock pulses. A reference signal is transmitted to the computer or processor; the reference has a frequency which is a whole-number fraction of the desired frequency. Upon receipt in the processor (16) of the reference signal, a counter (19) provided for counting of the clock pulses is preset.

  • Local area network coaxial cable connection device
    Patent number: 4902989
    Abstract: The possible length of tap lines to the serial bus of a local area network is extended to about 0.7 meter by inserting an inductance 2 into the serial bus 1, and connecting a further coaxial cable 7 to a central tap 3 of the inductance. Preferably, the inductance 2 is a printed-circuit pass-through filter. The longer tap lines are particularly useful for connection of rack-mounted digital equipment in broadcasting studios, where it is inconvenient to place the equipment directly adjacent to a typically floor-level network cable.
