Latest Patents

Christensen holds a patent for a "Dynamically converging electron gun system." This invention includes a cathode means for developing an electron beam and main focus lens means with multiple electrode means situated on a common axis. The system is designed to receive the electron beam and form a focused electron beam spot at the screen of the tube. The lens means is structured to create an asymmetrical focusing field component, which effectively diverts the beam from a straight-line path at a predetermined angle. This technology allows for varying voltages to be applied to the electrode means, enabling dynamic control over the beam's focal distance and direction.
