Patent number: 11754471Abstract: Techniques and methods for testing a structural integrity of a vehicle. For instance, the vehicle may use suspension(s) to lift corners of the vehicle, where lifting the corners creates a torsion force in the body of the vehicle. The vehicle may then use sensor(s) to determine a deflection that is caused by the torsion force. Next, the vehicle may determine a stiffness associated with the body of the vehicle using the force that was applied to lift the corners and the deflection. After determining the stiffness, the vehicle may compare the stiffness to a baseline stiffness in order to determine whether there is a problem with the structural integrity of the vehicle. The baseline stiffness may include s standard stiffness or be based on a previous test of the vehicle. If the vehicle determines that there is no problem, then the vehicle may continue to operate as intended.Type: GrantFiled: April 30, 2021Date of Patent: September 12, 2023Assignee: Zoox, Inc.Inventors: Johannes Edren, Ahditya Melkote, Keith David Myers

Publication number: 20220255095Abstract: Molten carbonate fuel cell configurations are provided that allow for introduction of an anode input gas flow on a side of the fuel cell that is adjacent to the entry side for the cathode input gas flow while allowing the anode and cathode to operate under co-current flow and/or counter-current flow conditions. It has been discovered that improved flow properties can be achieved within the anode or cathode during co-current flow or counter-current flow operation by diverting the input flow for the anode or cathode into an extended edge seal region (in an extended edge seal chamber) adjacent to the active area of the anode or cathode, and then using a baffle to provide sufficient pressure drop for even flow distribution of the anode input flow across the anode or cathode input flow across the cathode.Type: ApplicationFiled: February 11, 2021Publication date: August 11, 2022Inventors: Christopher Howard, Brandon J. O'Neill, Paul J. Rubas, Frank Hershkowitz, Lu Han, Lawrence J. Novacco, Frank J. Dobek, Keith David, Brian Bullecks

Patent number: 11047486Abstract: An expanding gate valve and method is provided for bidirectional sealing capability against pressure, whether the direction of pressure is upstream or downstream. The bidirectional annular seat seals against the gate assembly against pressure from the normal wellhead direction, typically upstream. For sealing against pressure in the opposite direction, the seat is formed with an annular recess extending radially outwardly from the central bore of the annular seat so that a flex portion of the seat formed between the recess and the front sealing face of the annular seat at the central bore flexes toward the gate assembly against this pressure. The front face of the bidirectional seat forms a raised annular sealing portion on the flex portion of the seat adjacent the central bore to provide sealing contact with the gate assembly in the expanded condition when the flex portion flexes toward the gate assembly.Type: GrantFiled: February 21, 2018Date of Patent: June 29, 2021Assignee: Stream-Flo Industries Ltd.Inventors: Keith David Farquharson, Tianle Guo, Thomas L.
