Publication number: 20250138540Abstract: An estimated target position is generated based on agent data received from an agent sensor system of a reinforcement learning (RL) agent and teammate data received from a plurality of teammate RL agents. An information metric reward is generated based on a confidence level associated with the estimated target position. The confidence level is based on the estimated target position and historical estimated target positions. A distance metric reward is generated based on an agent position and the estimated target position. A combined reward is generated based on the information metric reward and the distance metric reward. A movement action is generated for the RL agent based on the agent position, the estimated target position, and the combined reward in accordance with a multi-agent reinforcement learning (MARL) algorithm.Type: ApplicationFiled: October 25, 2023Publication date: May 1, 2025Applicant: General Dynamics Mission Systems, Inc.Inventors: Emily Beatty, Eric Dong

Patent number: 12060709Abstract: An example plasterboard includes a layer of hardened plaster material having a first surface and an opposed second surface and a layer of molded material having a surface that faces away from the layer of hardened plaster material. The surface of the layer of molded material has one or more raised features. The plasterboard also includes a liner between the first surface of the layer of hardened plaster material and the layer of molded material. Other examples include a method of forming such plasterboards and a method for installing such plasterboards.Type: GrantFiled: August 15, 2022Date of Patent: August 13, 2024Assignee: CertainTeed LLCInventors: Mithun N.

Patent number: 11624482Abstract: A leakage mitigation system includes a leakage detection device having a canister configured to: (i) contain a first reactant and a second reactant and, (ii) based on a volume of liquid leaked from a tank, allow the first reactant and the second reactant to react with each other to produce a gas. A shut-off valve coupled to an inlet pipe of the tank is configured to actuate between an open condition and a closed condition. Further, a conduit extending between the leakage detection device and the shut-off valve allows flow of the gas from the leak detection device to the shut off valve. In order to mitigate the leakage of water, the shut-off valve is actuated between the open condition and the closed condition based on the pressure exerted thereon by the flow of the gas.Type: GrantFiled: February 26, 2021Date of Patent: April 11, 2023Assignee: Rheem Manufacturing CompanyInventors: Saman Beyhaghi, Atilhan Manay, Eric Dong, Kyle Jiang, Christopher Mao, Benjamin Pham

Patent number: 11619044Abstract: An example plasterboard includes a layer of hardened plaster having a first surface and an opposed second surface, a layer of polymer material having particles of one or more cementitiously-active substances mixed therein, and a liner between the first surface of the layer of hardened plaster and the layer of polymer material. Another example is a method of forming such a plasterboard. The method includes loading an extruder with the polymer material having the particles of one or more cementitiously active substances mixed therein, extruding the polymer material through a die to form the layer of polymer material on a surface of the liner, contacting with a layer of wet plaster material, the liner having the polymer material applied thereon such that the surface of the liner faces away from the wet plaster material, and drying the layer of wet plaster material to form the layer of hardened plaster.Type: GrantFiled: December 23, 2018Date of Patent: April 4, 2023Assignee: CertainTeed Gypsum, Inc.Inventors: Mithun N. Kamath, Choung-Houng Lai, Michael J. Lemberger, Gerald Boydston, Bryan Wiltzius, Nathan Frailey, Eric Dong
