  • Network hub activity display
    Patent number: 6256318
    Abstract: The occurrence of collision and activity in a computer network is indicated by activation of a visual indication device. The device is activated for periods which are longer than the actual periods of collision and activity to permit the human eye to register the visual indications. This is particularly useful for high speed networks where the periods of collision and activity may be very brief.
