Patent number: 11442518Abstract: An extended system includes at least one peripheral component interconnect express (PCIE) connector and a control device. The PCIE connector is suitable for connecting to at least one server device. The control device is connected to PCIE connector. According to at least one working voltage generated by the server device, the control device turns on the extended system and ignores a power control signal generated by the extended system, or the control unit generates at least one wakeup signal according to the power control signal generated by the extended system and transmits the wakeup signal to the server device, so that the server device may turn on and generate a working voltage.Type: GrantFiled: July 19, 2019Date of Patent: September 13, 2022Assignee: WISTRON CORP.Inventors: Zh-Wei Zhang, Syu-Siang Lee

Patent number: 11228201Abstract: A power generating apparatus includes a power supply, a first sub-end circuit, a second sub-end circuit and an integrated signal generator. The first and second sub-end circuits respectively generate first and second sub-end standby power. The first sub-end circuit receives a first integrated control signal. The second sub-end circuit receives a second integrated control signal. The first sub-end circuit cuts off the first sub-end standby power according to the first integrated control signal and turns on the first sub-end standby power again after a first delay time. The second sub-end circuit cuts off the second sub-end standby power according to the second integrated control signal, and turns on the second sub-end standby power again after a second delay time. The integrated signal generator generates the first and second integrated control signals.Type: GrantFiled: July 19, 2019Date of Patent: January 18, 2022Assignee: Wistron CorporationInventors: Zh-Wei Zhang, Syu-Siang Lee

Patent number: 10782758Abstract: A framework for system power control of a dual-port non-volatile memory storage device is provided. The electronic system includes a storage device, two hosts and a control circuit within each of the two hosts. Each host filters signals for shortly turning off a power supply of the storage device during a process of boot and reboot of the host. When one of the hosts enters a turn-off state, it is detected whether another one of the hosts is running, and the one of the hosts does not control the power supply if the another one of the hosts is running. Two control signals of the two hosts control the power supply of the storage device through an AND gate.Type: GrantFiled: November 29, 2018Date of Patent: September 22, 2020Assignee: Wistron CorporationInventors: Syu-Siang Lee, Zh-Wei Zhang
