Patent number: 9276391Abstract: A fault-tolerant self-indicating surge protector system and methods are presented. An unwanted surge of electrical energy induced by a lightning strike is directed away from a sensitive electrical or electronic component, and the unwanted surge of electrical energy is directed through series connected pairs of varistors. A voltage signal is extracted from a center tap point between the series connected pairs of the varistors, and the voltage signal is monitored for a health of the varistors. A high impedance in a varistor among the varistors is provided for a low voltage across the varistor, and a low impedance in the varistor is provided and the unwanted surge of electrical energy is diverted through the varistor in response to a high voltage across the varistor.Type: GrantFiled: July 21, 2013Date of Patent: March 1, 2016Assignee: The Boeing CompanyInventors: Thomas R. Hasenoehrl, John T. Paterson, Marvin Whitney, Kevin S. Callahan, Shahriar Khosravani

Patent number: 9183983Abstract: A modular truss assembly for mechanically and electrically mounting system components of a modular equipment center (MEC). A plurality of MECs is spatially distributed throughout the vehicle to service equipment loads. The modular truss assembly provides different voltage levels for powering the system components of the MEC and for powering the equipment loads. In one or more configurations, a MEC incorporate inductive power coupling for powering a line replaceable unit (LRU) in proximity to the modular truss assembly without exposed electrical connections and such that the MEC may forgo power conversion equipment. In one or more configurations, a sensor is embedded in one or more transfer layers of the truss for measuring a power trace embedded in the modular truss assembly.Type: GrantFiled: October 11, 2013Date of Patent: November 10, 2015Assignee: THE BOEING COMPANYInventors: Mark E.

Patent number: 8836160Abstract: Presented is a system and method for providing electrical isolation in vehicle power systems. The method comprises placing linear optimized isolation transformers in structures of a vehicle at positions that minimize the propagation of energy spikes into internal electronic systems, for example in the wing root of an aircraft where electrical cables from a generator associated with an engine enter the fuselage. The system includes a linear optimized isolation transformer with a core that has primary side winding isolated from a secondary side winding by an isolation dielectric. The isolation dielectric maintains a high value isolation independent of pressure differences due to operation at different altitudes.Type: GrantFiled: September 28, 2010Date of Patent: September 16, 2014Assignee: The Boeing CompanyInventors: John T.

Patent number: 8421398Abstract: An autonomous controller allows an AC induction motor to operate over a broad range of AC power supply frequencies by reducing the amount of current supplied to the motor at lower frequencies. The controller detects the frequency of the power supply and switches the supply current on and off during each AC cycle to limit the RMS current to a value that is related to the detected frequency. Alternatively, the controller switches capacitive reactance into the power supply circuit which reduces the current supplied to the motor at lower AC frequencies.Type: GrantFiled: February 16, 2010Date of Patent: April 16, 2013Assignee: The Boeing CompanyInventors: Robert E. Fisher, John T. Paterson
