Abstract: A method and apparatus for diminishing display transients and jitter. The method and system disclosed utilizes prior illumination and position histories in displaying and illuminating representations, and elements comprising the representations, on the display. Recognizing repeated representations, finding their prior and current positions, and determining if the difference in position is over a threshold value, diminishes the jitter by displaying the representation in the new position if over the threshold value, or, if it is not over the threshold value, then displaying it in the prior location. The illumination of an element at an intensity, which is based on prior illuminations and/or intensities of the element, diminishes the transients by avoiding flashing or flicker of transient illuminations.

Abstract: A method and apparatus for converting interwoven digital video signal to raster video signal utilizing a plurality of buffers with the functions of reading the interwoven video signal and sending the raster video signals. The method writes the interwoven video data in a substantially interspacing manner, and then reads the raster video signal out in a substantially contiguous manner. This method preferably writes to a first buffer while reading a second buffer and then alternates the function of the buffers by reading from the first buffer and writing from the second buffer.

Abstract: A solid-state switch in a deflection circuit includes a plurality of field-effect transistors (Q7, Q8, and Q9) connected in series. Each of the transistors (Q7, Q8, and Q9) is part of a switching module (20, 22, and 24) in the form of a three-terminal transistor circuit. Two of the modules (20 and 22) are connected to a common gating terminal (12) solely by diodes (D6 and D7) oriented so as (a) to conduct current in the direction required to provide a turn-on signal for the transistors (Q7 and Q8) but (b) to isolate the common gating terminal (12) from the high voltages experienced by the transistors (Q7 and Q8) when they are in their non-conducting states.

Abstract: A video circuit enclosure for housing a video circuit, such as a video amplifier circuit that is used to drive a cathode ray tube is disclosed. The video circuit enclosure includes a video box with an open face through which the cathode ray tube is inserted. A video board, on which the video circuit is mounted is secured inside the video box. A heat sink is attached to one end of the video box and is a thermal path with heat-generating components on the video board. A socket board, located inside the video box, is mounted to the cathode ray tube. The socket board is located in the video box so it is slightly spaced away from the video board. A video cover is attached to the socket board and spaced away therefrom so it covers the open face of the video box. A set of spring loaded pin contacts attached to the socket board abut contact pads on the video board so as to provide a low impedance electrical slip connection between the boards.
