A system for identifying articles in accordance with light transmission through the article includes a light sensor which provides a signal indicative of the light transmission. A circuit responds to the signal and provides an output in accordance with the transmission levels. The output is provided to a control to identify the article and to adjust the illumination level to the article.

Apparatus for identifying articles from received illumination with light

In measuring the dots of a color picture tube panel the panel is scanned and energy passing through the dots is detected. A large number of lines are scanned and the scan data are stored in a matrix having a row for each scan line and, columns for the dots and the spaces between the dots. Data for a preselected number of dots and spaces are stored. When scanning occurs between rows of dots, the preselected number of dots is not scanned and zeros are put into the matrix. Data processing is simplified by searching the last column of the matrix for zeros and rejecting all rows of data having a zero in that column.

Method measuring transparent elements and an opaque medium

An auxiliary focusing circuit for an automatic focusing solid state array camera includes a control circuit and a drive circuit. The camera includes a switch which is actuated when the lens travels a selected distance without being focused. The control circuit responds to the switch and actuates the drive circuit. The switch also reverses the direction of travel of the lens. The drive circuit rotates an optical scanning member and the camera can be focused while the lens travels in the opposite direction.
