Latest Patents

One of his latest patents is the "Two slit illumination aperture." This invention comprises a three-piece aperture with a centerpiece positioned like an 'island' between two outer pieces, forming two light transmissive slits. The outer pieces may contain symmetrical light transmission edges, making this aperture particularly useful in electrophotographic copier machines where substantially continuously variable reduction is practiced. Another significant patent is the "Light pipe for accurate erasure of photoconductor charge." This erase apparatus utilizes an array of light-emitting diodes (LEDs) placed adjacent one end of a light channel, with the other end adjacent to a moving photoreceptive surface. The channel allows light rays to pass freely from LED to LED while containing the rays in a direction parallel to the photoreceptor movement.
