Open the CIPO recordAbstract From the Canadian patent
An excessive duty cycle and pulse width limiter comprises two constant current sources responsive to changes in a control input signal to provide a constant voltage charge and discharge current to a capacitor whose voltage level is sensed by a tripping circuit. The circuit effectively measures duty cycle and is used as a protective limiter, providing output pulse blanking signals to load circuitry.
