Patent number: 11930462Abstract: Precision digital chronography based on detected changes in state of a processor is described. The changes in state may be detected by another processor and an averaged time interval generated. A signal corresponding to the averaged time interval may be communicated to a distributed database and propagated to remote systems. Devices associated with the remote systems may adjust or set a device clock in accordance with the averaged time interval.Type: GrantFiled: June 13, 2023Date of Patent: March 12, 2024Assignee: T-MOBILE INNOVATIONS LLCInventors: Lyle W. Paczkowski, Peter P. Dawson, Ronald Richard Marquardt, Walter F. Rausch

Publication number: 20240075636Abstract: A tool interchange for a submersible remote operated vehicle (ROV) arm includes a first interchange body that affixes to an ROV arm. A second interchange body is carried by the first interchange body to rotate on a rotation axis. The second interchange body includes a tool mount actuable between gripping an ROV tool to the second interchange body and releasing the ROV tool from the second interchange body. An inductive power coupling part is provided in the tool mount. The inductive power coupling part is presented outwardly in the tool mount opposite the first interchange body, resides on the rotation axis and is fixed with respect to the first interchange body while the second interchange body rotates. The inductive power coupling part is adapted to inductively communicate power with a corresponding inductor power coupling part of the ROV tool when the ROV tool is docked in the tool mount.Type: ApplicationFiled: July 10, 2023Publication date: March 7, 2024Inventors: Richard Brian Correll, William P. Klassen, Clayton Paul Kleppinger, Philip David Langley, Justin Daniel Schmaljohann, Ryan Mitchell Bosler, William Dawson Kesling, Chris Alexander Ade

Patent number: 11349155Abstract: An electrolyte element (10) comprises a perforated sheet (11) of non-reactive metal such as an aluminium-bearing ferritic steel, and a non-permeable ceramic layer (16b) of sodium-ion-conducting ceramic bonded to one face of the perforated sheet (11) by a porous ceramic sub-layer (16a). The perforated sheet (11) may be of thickness in the range 50 ?m up to 500 ?m, and the thickness of the non-permeable ceramic layer (16b) may be no more than 50 ?m, for example 20 ?m or 10 ?m. Thus the electrolyte properties are provided by the non-permeable thin layer (16b) of ceramic, while mechanical strength is provided by the perforated sheet (11). The electrolyte element (10) may be used in a rechargeable molten sodium-metal halide cell, in particular a sodium/nickel chloride cell (20). It makes cells with increased power density possible.Type: GrantFiled: October 12, 2018Date of Patent: May 31, 2022Inventor: Richard Dawson

Patent number: 10900531Abstract: Spring rings and closed wire loops each can have two ends that are connected. The connected ends can be welded. The connected ends can be aligned for welding by incorporating complementary surfaces so that when joined, the tip at the first end mate to the tip at the second end. The mating can be self-aligning spatially and radially. The spring rings and the closed wire loops can be used in many applications, including in connector applications and seal applications.Type: GrantFiled: August 30, 2018Date of Patent: January 26, 2021Assignee: Bal Seal Engineering, LLCInventors: Richard Dawson, Tobias Schelbert
