  • Patent number: 5922282
    Abstract: Very rapid diagnosis and sensitivity testing can significantly stem the growing Tuberculosis epidemic in the United States, caused by susceptible AIDs patients and the occurrence of antibiotic resistant mycobacilli. Thus I have invented an automated computerized microscope, the ATBD unit, and slide module to diagnose and test patient's sputum by examining individual living mycobacteria from the patient sample with no culturing required. The diagnosis and sensitivity testing is accomplished in minutes or hours, instead of the current weeks to months. The system inserts a plasmid, specific for M. tuberculosis, carrying the luciferase gene into the mycobacteria by improved electroporesis on the slide. Luminescence indicates tuberculosis. Then the mycobacteria are bathed in antibiotics, and if the luminescence is not turned off, the patient's bacteria are resistant. A phage carrying the luciferase gene can also be used to infect the M.TB.

  • Patent number: 5594672
    Abstract: A device that saves energy by turning on power to a peripheral device such as a printer only when a host computer sends data to its I/O port. When the peripheral device requires a warm-up period, the device will mediate the transition of the peripheral between a power-off state and a ready state by using a hold-off timer function.

  • Patent number: 5293271
    Abstract: An optical system for use in helmet mounted displays that consists of an image source, electronics that predistort the image emanating from the projector, a means for correcting for optical aberration that may be a lens or a fiber optic taper, and a reflective surface composed of a plurality of reflective surface elements with conic geometries. Light from the projector, corrected for optical aberrations, is directed into the first reflective surface element. Light from the first reflective surface element is reflected into a second reflective surface element and thereafter into the eye.
