Résumé : The device described is a simple circuit functioning as a normally open switch controllable by electrical signals. It has several modes of operation, permitting full use of the different capabilities of the C4 camera (single frames, repetitive frames, moving film). Depending on the mode, either short triggering pulses or rectangular gating signals of adjustable duration are needed for driving the circuit. A square wave stimulator, for instance, can be used to deliver the appropriate signals.
