  • Apparatus and method for measuring and displaying the pulse width of a video signal
    Patent number: 4571617
    Abstract: An apparatus and method is shown for measuring the width of a data pulse of a video signal containing a synchronizing pulse associated with each data pulse. Every N.sup.th data pulse is measured and a digital representation of the measured value is displayed in standard units of length for viewing by a human observer.

  • Line cathode heating and protection circuit
    Patent number: 4464611
    Abstract: A circuit for pulse heating a line cathode also protects the cathode from voltage and current surges. An adjustable voltage regulator provides a regulated voltage to a pulse generation circuit. The voltage regulator has a control input which is used to control the regulator output. The voltage on the control electrode is controlled by a control circuit which is actuated by a logic circuit. The logic circuit and the pulse generator are responsive to the horizontal synchronization pulses of the display device containing the line cathode.
