Patent number: 11272273Abstract: A signal transmission apparatus comprises a base and a shell, wherein a top portion of the base has a signal transmission device. The shell is covered above the base. A cavity is formed inside the shell. The cavity is in communication with an opening of a bottom portion of the shell. And the shell comprises a ceramic shell body and an inner covering layer. The inner covering layer is fully attached to an inner surface of the ceramic shell body. Therefore, the signals of the signal transmission device can pass through the shell so that the signal transmission device can receive or transmit signals. And through the strong adhesion of the inner covering layer, the ceramic shell body can be kept intact without being broken into a lot of debris when the ceramic shell body is impacted by external force or suddenly dropped.Type: GrantFiled: August 6, 2020Date of Patent: March 8, 2022Assignee: HOCHENG CORPORATIONInventors: Che-Yuan Liu, Chang-Hsing Lee, Ming-Chuan Liu, Zhao-Xu Lai, You-Ning Hsiung, Chia-Chang Hsu, Pen-Chien Yu, Shu-Fen Wang

Patent number: 11089707Abstract: Embodiments disclosed herein provide an apparatus to enable smooth and safe assembly of functional modules to computer chassis. The apparatus includes a chassis and a pair of racks mounted to the chassis. Each rack has a plurality of gear teeth formed thereon. A module having a housing is slidably coupled to the chassis and disposed between the pair of racks. A pair of gear pinions are rotatably mounted to the housing and meshed to the gear teeth of one of the racks. A damping member is coupled between each gear pinion and the housing. A sliding movement of the housing relative to the chassis rotates the pair of gear pinions to roll over along the gear teeth. During the sliding movement of the housing, the damping member exerts a resistance force against the housing, to reduce the movement speed of the housing.Type: GrantFiled: August 26, 2019Date of Patent: August 10, 2021Assignee: Lenovo Enterprise Solutions (Singapore) Pte. Ltd.Inventors: Chang-Hsing Lee, Chia-Ching Huang, Ta-Wei Chen, Sung-Feng Chen, Ming Jie Chai

Patent number: 11061454Abstract: An apparatus comprises a memory slot mounted to a main board, an expansion slot mounted to the main board and electrically coupled to the memory slot, a backup power module receivable in the expansion slot, and a main power source electrically coupled to the expansion slot and the memory slot. During normal operation, the main power source supplies electrical power to the memory slot and charge the backup power module. In the event of power loss or main power source failure, the backup power module discharges electrical power to the memory slot.Type: GrantFiled: July 30, 2019Date of Patent: July 13, 2021Assignee: Lenovo Enterprise Solutions (Singapore) Pte. Ltd.Inventors: Shih Ming Fan Chiang, Zhi Da Huang, Chang-Hsing Lee, Chihwei Wu

Patent number: 11029736Abstract: A support apparatus for supporting a hard disk drive in a computer system to enable hard disk replacement under hot-swap operations, the apparatus comprises a rail, a primary bracket coupled to the rail, and a cage to which a hard disk drive is mountable and coupled to the primary bracket. The rail is mountable to a base element such as a main board or the chassis of a computer system. The cage is movable relative to the rail from an operating position to a first cage position, and subsequently from the first cage position toward a second cage position to provide a clearance space in front of the cage, in order to allow the hard disk drive mounted in the cage to be drawn out from the cage for replacement under hot-swap operations.Type: GrantFiled: July 23, 2019Date of Patent: June 8, 2021Assignee: Lenovo Enterprise Solutions (Singapore) Pte. Ltd.Inventors: Morgan Wu, Chia-Ching Huang, Tony Liu, Chang-Hsing Lee

Patent number: 10798844Abstract: An apparatus provides an extendable rail assembly including a track for securing to a rack, a first rail slidably coupled to the track, and a second rail slidably coupled to the first rail. The first rail is movable relative to the track between retracted and extended positions, wherein the first rail includes first and second rail sections coupled together by a pivot joint. The second rail is movable relative to the first rail between retracted and extended positions. Furthermore, with the first rail in the extended position and the second rail in the extended position, the pivot joint allows the second rail and the second rail section of the first rail to pivot relative to the track and the first rail section of the first rail. A pair of rail assemblies may be secured to a rack to support a member, such as a server.Type: GrantFiled: August 17, 2018Date of Patent: October 6, 2020Assignee: LENOVO ENTERPRISE SOLUTIONS (SINGAPORE) PTE. LTD.Inventors: Chang-Hsing Lee, ZhenDe Fu, Wan-Ya Lin, Jui-Yun Chang
