Patent number: 10954005Abstract: A spacecraft includes a power train that includes a solar array, an electric propulsion subsystem, and a power conversion module. The power conversion module receives power from the solar array at a voltage, Vi; and delivers power to the electric propulsion subsystem at a voltage, Vo. The spacecraft is configured to operate at a varying distance, D, from the sun within the range of Dmin to Dmax, Dmax being at least 1.3×Dmin. The solar array is configured to deliver power to the power conversion module at a voltage approximately equal to Vo when the spacecraft is proximate to Dmax.Type: GrantFiled: July 25, 2017Date of Patent: March 23, 2021Assignees: Space Systems/Loral, LLC, California Institute of TechnologyInventors: Peter Warner Lord, Gregory Alan Carr, Jorge Delgado, Dan Michael Goebel, Bao Hoang, David Younghee Oh, Lee Charles Rotlisberger, Christopher Bryan Stell, Denis Trofimov

Patent number: 10082133Abstract: Hall thrusters with conductive coatings are disclosed. A Hall thruster comprises magnetic shielding in order to avoid collisions with the inner walls of its discharge chamber. By removing the source of erosion, the walls of the chamber can be removed reducing mass, cost and complexity of the thruster. A conductive coating, such as an aluminum coating, is deposited on inner screens between the discharge chamber and the magnetic poles of the thruster. The magnetic field within the chamber shields the conductive coating deposited on the inner and outer screens of the chamber.Type: GrantFiled: March 8, 2016Date of Patent: September 25, 2018Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGYInventor: Dan Michael Goebel

Patent number: 9944316Abstract: Vehicle control systems that can be used, for example, to configure a vehicle (e.g., a lawn tractor or riding lawn mower) to make low- to substantially zero-radius turns. Some of the present vehicle control systems utilize at least one steered wheel position sensor to generate a signal that indicates the actual position of the steerable structure (e.g., wheel) to which the sensor is coupled, rather than a projected or anticipated position of that steerable structure. Vehicles that include such control systems.Type: GrantFiled: October 22, 2012Date of Patent: April 17, 2018Assignee: MTD Products IncInventors: Michael Goebel, Derek Kaesgen
