Abstract: The effects of friction and vibration are eliminated from an automatically regulated iris, optical filter, or similar arrangement by employing an electroresponsive drive motor with translational drive means. Iris blades or the like are secured to flexible members, the flexure of which is varied by translational motion of the drive system in response to low-power control signals. With this construction, sliding friction is avoided and the system is virtually nonresponsive to vibration.

Abstract: AN ELECTRORESPONSIVE LIGHT REGULATING DEVICE IS CONSTRUCTED WITH A PAIR OF LIGHT CONTROLLING ELEMENTS SUCH AS FILTERS OR IRIS BLADES MOUNTED ON A PAIR OF CANTILEVER SPRING MEMBERS. THE CANTILEVER SPRINGS ARE CONNECTED TOGETHER BY A TAUT BAND AND A METER MOVEMENT IS POSITIONED TO ENGAGE AND DISPLACE THE TAUT BAND AND THUS ALTER THE RELATION OF THE LIGHT CONTROLLING ELEMENTS.

Abstract: Precise automatic gain control is achieved by sampling the amplitude of individual ones of the synchronizing pulses of a received composite video signal. Spurious gain changes are minimized by deriving drive signals for initiating sampling of the synchronizing pulse amplitude from each of the individual synchronizing pulses.
