摘要： A circuit which compensates for the effects of drift that occur during the operation of a cathode ray tube because of temperature changes or aging and which produces changes in intensity of the picture on the cathode ray tube by sensing the intensity changes and varying the bias on the second grid of the cathode ray tube to restore the desired intensity.

摘要： Apparatus for use with range finding equipment in which the radiation from a remote object may be too small to provide for proper operation. A signal which is a function of the logarithm of the ratio of the output of a first and second detector and a signal which is the function of the logarithm of the ratio of a third and fourth detector is compared with a reference signal. If the reference signal is larger than both of the other signals, the system operates to focus at a predetermined position.

摘要： Range finding equipment for use with optical systems utilizing a small number of radiation detectors positioned to receive radiation in first and second patterns from a remote object. The sum of the logarithm of the ratio of a first and second detector and the logarithm of the ratio of a third and fourth detector is compared with the difference between the logarithm of the ratio of the first and second detector and the logarithm of the ratio of the third and fourth detector to determine which has the greatest absolute magnitude. The signal of greatest magnitude is selected to operate the range finding circuitry.

摘要： A support for a camera automatic focusing system has two identical plates that form top and bottom covers of the support. The top plate has a plurality of spaced openings that are in alignment with identical spaced apart openings formed in said bottom plate. A pair of shafts are positioned to extend through a different pair of the aligned openings in the plates. A separate image transferring mirror and a focusing lever is mounted on each shaft between opposing flat surface portions of the cover plates. A separate washer is mounted about each of said shafts between a lower end of said mirror and its associated focusing lever. An image receiving module having a height greater than the combined height of the mirror and thickness of the washer allows each focusing lever to be moved freely for angular adjustment of the associated mirror. The module has aligned spaced apart bosses on its surfaces adjacent the cover plates. Additional pairs of aligned openings formed in the top and bottom cover plates are positioned in snug engagement with associated bosses on said module. A mechanical connection extends between said cover plates to retain said image receiving module and said mirrors in optical relationship.
摘要翻译：对于相机自动对焦系统的支持具有形成支撑件的顶盖和底盖的两个相同的板。顶板具有与形成在所述底板中的相同间隔开的开口对准的多个间隔开的开口。一对轴被定位成延伸通过板中不同对的对齐的开口。单独的图像转印镜和聚焦杆安装在每个轴上，在盖板的相对的平坦表面部分之间。在所述反射镜的下端和其相关联的聚焦杆之间，围绕每个所述轴安装单独的垫圈。具有高于镜子的组合高度和垫圈厚度的图像接收模块允许每个聚焦杆自由移动以便相关联的镜子进行角度调节。该模块在邻近盖板的表面上具有对准的间隔开的凸起。形成在顶盖板和底盖板中的另外成对的对齐开口定位成与所述模块上的相关联的凸起贴合接合。机械连接在所述盖板之间延伸，以保持所述图像接收模块和所述反射镜的光学关系。
