    Abstract: A device is disclosed for recording high frequency signals on a lower frequency recorder. In accomplishing this, the high frequency signals are amplified and periodically stored in maximum and minimum storage devices. The stored maximum and minimum values of the high frequency signal are then sequentially applied through read amplifying circuitry to the lower frequency recorder which displays the signal retaining the amplitude thereof.

    Abstract: A focus detecting system includes a lens device for forming an image of an object on a predetermined plane through an optical path. A light gate positioned in the optical path is operable to alternately mask a portion of the optical path. A light responsive device is positioned at the predetermined plane to respond to the unmasked light from the lens device for producing electrical signals representative of the instaneous intensity distribution of the light received thereby. The intensity of the light falling on the light responsive device is modulated by the action of the light gate and varies as a function of the condition of focus of the image. A signal processing circuit responds to the electrical signals to provide an output signal indicative of the condition of focus of the image.

    Abstract: A focus detecting system includes a lens device for forming an image of an object on a predetermined plane through an optical path. A light responsive device is positioned at the predetermined plane to respond to the light from the lens device for producing electrical signals representative of the instaneous intensity of the image formed thereon. A movable and a stationary apertured masks are arranged in the optical path between the lends device and the light responsive device to cyclically vary the light angle of access from the lens device to the light responsive device as the apertures in the movable mask are cyclically moved with respect to corresponding apertures in the stationary mask. The intensity distribution of the light falling on the light responsive device is modulated by the operation of the masks and varies as a function of the condition of focus of the image. A signal processing circuit responds to the electrical signals to provide an output signal indicative of condition of focus of the image.
