Drew Robert Johnson 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).

  • Patent number: 9356399
    Abstract: An aircraft ground power connector for use in an aircraft ground power support system providing electrical power from a ground power unit through a ground power cable to the ground power receptacle of a parked aircraft. The axis of the portion of the connector housing which engages the aircraft ground power receptacle is angled relative to the axis of the portion of the housing which receives the ground power cable to minimize mechanical stress on the aircraft ground power receptacle when the connector is installed therein and to render the connector easier to insert and remove from the aircraft receptacle. Additionally, the ground power connector includes a capacitor connected to an electrical circuit within the connector supplying do voltage to the aircraft ground power receptacle to mitigate momentary voltage drops at the receptacle resulting from momentary surges in current demand by the aircraft.
    Type: Grant

  • Patent number: 8405249
    Abstract: An airplane ground support system includes a multi-voltage power supply. A control system within the power conversion module receives measurements to regulate the power module's output to a predetermined preset voltage level as mandated by the power output selection signal. In an alternate embodiment a multi-voltage or upgradable power supply has A.C. and D.C. capability, A.C. only capability with an upgrade kit available to add D.C. capability in addition to the A.C. capability, D.C. only capability with an upgrade kit available to add A.C. capability in addition to the D.C. capability.
