Patents by Inventor Mark Frontera

Mark Frontera has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Energy imaging with generally constant energy separation
    Patent number: 9970889
    Abstract: The present inventors have recognized that fall times between high-kV to low-kV levels (during a “dual energy” or “fast-kV” energy scan) are linked to the discharge of HV (high voltage) capacitance. In an embodiment of the invention, a high voltage generator may be activated during fall transitions from first to second energy levels in order to substantially maintain a predetermined fall transition time. Accordingly, substantially equal energy distributions between high-kV and low-kV levels may be achieved.
    Type: Grant
    Filed: March 16, 2015
    Date of Patent: May 15, 2018
    Assignee: General Electric Company
    Inventors: Jean-Francois Larroux, Julien Bouhraoua, Aurelien Gadenne, Uwe Wiedmann, Mark Frontera

  • High flux X-ray target and assembly
    Patent number: 7751530
    Abstract: An X-ray tube anode assembly, an X-ray tube assembly and a method for heat management to an X-ray assembly having a movable X-ray target having a target surface. The anode assembly includes a drive member arranged and disposed to provide oscillatory motion to the target assembly and a target surface that is configured to remain at a substantially fixed distance from a cathode assembly during oscillatory motion.
