Patent number: 11371721Abstract: A thermostatic radiator valve (TRV) assembly or automatic temperature balanced actuator (ABA) assembly controls a manifold assembly through a push pin bearing mechanism. The push pin bearing mechanism comprises a push pin that moves in a linear direction responsive to rotational movement of a motor gear that is coupled through a helical gear. Rotational movement of the push pin is prevented by a ball bearing assembly. Movement of the push pin is transferred to a manifold pin, which in turn, controls the manifold assembly. Because the push pin moves in a linear rather than a rotational fashion, erosion of the mated manifold pin is substantially reduced with respect to transitional approaches.Type: GrantFiled: November 9, 2020Date of Patent: June 28, 2022Assignee: Computime Ltd.Inventors: Dick Kwai Chan, Hamza Yilmaz, Ben Ren Tan, Wai-Leung Ha

Patent number: 11315883Abstract: An apparatus includes a substrate including an identification code on a first side of the substrate and near a perimeter of the substrate. The apparatus includes a stiffener structure attached to the first side of the substrate. The stiffener structure has a cutout in an outer perimeter of the stiffener structure. The stiffener structure is oriented with respect to the substrate to cause the cutout to expose the identification code. The cutout may have a first dimension and a second dimension orthogonal to the first dimension. The first dimension may exceed a corresponding first dimension of the identification code and the second dimension may exceed a corresponding second dimension of the identification code, thereby forming a void region between the identification code and edges of the stiffener structure.Type: GrantFiled: November 12, 2019Date of Patent: April 26, 2022Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Suming Hu, Roden Topacio, Farshad Ghahghahi, Jianguo Li, Andrew Kwan Wai Leung
