Monoscope

Abstract: A cathode ray display system in which characters are generated by a monoscope and in which the character address information for the entire raster of a cathode ray tube display is stored in a dynamic memory which is continuously read and regenerated by character entry and read-out logic which controls the monoscope scanning to supply the proper characters to the cathode ray tube as it scans in a raster.

Abstract: A system for electronically representing in wave form plural physiological phenomena, viewing this representation, and simultaneously obtaining a labeled permanent photographic record of the representation. While of general application, the system has particular utility in low-cost medical observance and recordation of electrocardiogram wave forms. The data from the patient is presented on the cathode ray tube of an oscilloscope. This representation is viewed via an assembly of mirrors by the observer and simultaneously by a camera. When the observer is content with the output, he activates the camera which takes a permanent picture of the wave forms displayed on the cathode ray tube. The camera shutter is synchronized with the cathode ray tube display such that the shutter is held open for one complete sweep of the electron beam.

Abstract: A picture tube drive apparatus for driving a color picture tube. The picture tube drive apparatus comprises a video output circuit which receives video signals, amplifies them and outputs the amplified video signals, a picture tube drive circuit which receives the video signals amplified by the video output circuit for driving said color picture tube based on video signals, said picture tube drive circuit having means for detecting a beam current corresponding to the brightness of each color flowing through said picture tube, a picture tube connected with said picture tube drive circuit for displaying the video signals, a white balance control circuit into which a detection value of a beam current detected by said picture tube drive circuit is inputted and for outputting video signal level compensation signals for adjusting the white balance of the video image displayed on said picture tube to said picture tube drive circuit. A color picture tube in which an electron shield frame having at most a width which will not prevent electron beam from flying onto said shadow mask from an electron gun and having a function to suppress the reflection of the electron beam on a fluorescent screen is disposed on the inner peripheral surface of said electron on the side of the electron gun with respect to a shadow mask mounting position in the color tube.

Abstract: A novel camera attachment converts a standard daylight camera into a day/night-vision video camera. The attachment device (80) has a threaded input and output to physically and optically interconnect an auto-iris lens (60) to a video camera (64). The attachment device (80) contains an image intensifier tube (61) and a fiber optic image conduit (67) either of which may be switched into the through optical path to receive and either amplify or simply conduct the light image to a relay lens (84). The relay lens (84) focuses the output image from either the image tube or the fiber optic image conduit (67) onto the optical input of the video camera. The switching of the image intensifier tube (61) or the fiber optic image conduit (67) is dependent upon the ambient light conditions of the camera so that if there is insufficient lighting for normal daytime viewing the image tube is activated and switched into the through optical path of the camera.
