Abstract: The classic simplicity of the on-off switch undergoes considerable modifications for use on remote and/or unattended control cameras operated without the benefit of a human specialist. Discussed are the incorporation of design elements which, via sensed data on magnetic-striped film, are able to supply the camera with one-shot lubrication, set the selsyn-coupled zoom lens, provide continuous electromagnetic readjustment of the pulldown claw, start and stop the camera at preset intervals and, finally, make a record of all control functions executed by the system. This type of secondary intelligence is useful whenever a coherent performance record must be obtained over very long periods of time. The magnetic stripe is precoded with given audio frequencies under darkroom conditions and is read out by common pickup modes. Tuned resonators allow for proper discrimination and channel the cue to an associated electronic trigger.
