Patent number: 11679726Abstract: Vehicle sensor systems include modular sensor kits having one or more pods (e.g., sensor roof pods) and/or one or more bumpers (e.g., sensor bumpers). The sensor roof pods are configured to couple to a vehicle. A sensor roof pod may be positioned atop a vehicle proximate a front of the vehicle, proximate a back of the vehicle, or at any position along a top side of the vehicle being coupled, for example, using a mounting shim or a tripod. The sensor roof pods can include sensors (e.g., LIDAR sensors, cameras, ultrasonic sensors, etc.), processing units, control systems (e.g., temperature and/or environmental control systems), and communication devices (e.g., networking and/or wireless devices).Type: GrantFiled: November 10, 2021Date of Patent: June 20, 2023Assignee: CYNGN, INC.Inventors: Ain McKendrick, Michael W.

Patent number: 10584751Abstract: A load reduction assembly includes an annular bearing cone configured to extend between a bearing assembly and a frame assembly and form a first load path therebetween. The load reduction assembly further includes an annular recoupler member configured to extend between the bearing assembly and the frame assembly and form a second load path therebetween. The second load path is parallel to the first load path. The recoupler member includes a shape memory alloy configured to change stiffness in response to a change in a stress condition, thereby regulating an imbalance condition of a rotor shaft coupled to the bearing assembly.Type: GrantFiled: December 19, 2018Date of Patent: March 10, 2020Assignee: General Electric CompanyInventors: Shuvajyoti Ghosh, Akash Joshi, Shivaram AC, Ravindra Shankar Ganiger, Praveen Sharma

Patent number: 10196934Abstract: A rotor support system for a gas turbine engine may generally include a bearing assembly and a load reduction member configured to be coupled between the bearing assembly and a support frame of the engine. The load reduction member may include a fuse portion configured to fail when a load transmitted through the load reduction member exceeds a predetermined load threshold. The system may also include a load recoupling member provided between the bearing assembly and the support frame. The load recoupling member may be formed from a super-elastic shape memory alloy that allows the load recoupling member to undergo recoverable deformation without failing when the fuse portion fails such that the load recoupling member maintains a mechanical connection between the bearing assembly and the support frame.Type: GrantFiled: February 11, 2016Date of Patent: February 5, 2019Assignee: General Electric CompanyInventors: Esuff Khan, Shivaram Ac, Vidyashankar Ramasastry Buravalla, Shuvajyoti Ghosh, Akash Joshi
