Latest Patents

One of Dressel's latest patents is for a white light source. This invention describes a method in which a trivalent metallic ultraphosphate is irradiated with a low voltage electron beam. The metallic ions used are generally restricted to lanthanide rare earth ions and yttrium. The material emits light in a spectral continuum centered in the visible portion of the electromagnetic spectrum, in addition to any narrow bandwidth light emission associated with the transition of the metallic ion involving the electrons of the 4f shell. Another significant patent is for a double grid electron gun system and method of use. This invention provides an electron gun for use in a cathode-ray tube, featuring two control grids between the cathode and an accelerating electrode. The control grids are equipped with separate control voltages that carry the same intensity-modulation information for controlling the electron beam from the cathode. This innovative design allows the area of the cathode emitting the electron beam to remain approximately constant over a wide range of control voltage.
