Abstract: A top/bottom pincushion correction amplifier has an inhibit terminal that is coupled to vertical deflection means for receiving an inhibit pulse that corresponds to a vertical retrace pulse in the yoke. A vertical amplifier feeds the yoke in series with the secondary winding of a pincushion transformer, the primary winding of which is supplied with a pincushion correction signal from the pincushion amplifier. The effect of the retrace pulse in the yoke in causing ringing in the pincushion transformer is nullified by the inhibit pulse which increases the output impedance of the pincushion amplifier.

Abstract: The container of the present invention includes a box for housing an operatively connected closed circuit television system and having a front end for being opened. A packaging means holds the monitor and camera oriented within the box so that the lens of the camera and the screen of the monitor face the front end of the box. The packaging means also holds the camera and monitor such that the lens can be focused and picture controls on the monitor adjusted by accessing same through the front end. A power cord for connecting the system to an external power source is also accessible from the front end. Upon applying power, the monitor will display the view from the front end of the box as seen by the camera therein testing the system while in the shipping container. A method for testing such a system within the shipping container is also provided.
