Patent number: 9777736Abstract: A backflow prevention device includes a plurality of flaps that are connected pivotally to a casing of a fan. When a blade unit of the fan rotates to generate an airflow entering the casing via an airflow inlet and exiting the casing via an airflow outlet, the flaps are driven to pivot away from the blade unit to open positions, where the flaps serve as stator blades for the fan. When rotation of the blade unit is stopped, the flaps are driven by a reverse flow directed toward the airflow outlet and the blade unit to pivot toward the blade unit to closed positions, where the flaps close the airflow outlet to prevent air from entering the casing via the airflow outlet.Type: GrantFiled: October 9, 2014Date of Patent: October 3, 2017Assignee: Wistron CorporationInventors: Wei-Ta Shih, Shih-Huai Cho

Patent number: 8717209Abstract: Various pipeline ADCs are disclosed that substantially compensate for interference or distortion that results from imperfections with various ADC modules of the pipeline ADCs. The pipeline ADCs include various ADC stages and various compensation stages that are coupled to the various ADC stages. The various ADC stages convert their corresponding analog inputs from an analog signal domain to a digital signal domain to provide various digital output signals and various analog residual signals to subsequent ADC stages. The various compensation stages compensate for interference or distortion that is impressed onto the various analog residual signals which results from imperfections within previous ADC stages.Type: GrantFiled: September 5, 2012Date of Patent: May 6, 2014Assignee: Broadcom CorporationInventors: Jiangfeng Wu, Tianwei Li, Wenbo Liu, Wei-Ta Shih, Chun-Ying Chen, Lin He, Randall Perlow, Binning Chen, Ramon Gomez

Patent number: 8654532Abstract: A cooling coolant pipe of a server cabinet includes multiple tube bodies interconnected in series and at least one adjustable valve. In each of the tube bodies a first chamber and a second chamber that are adjacent to and separated from each other, the second chambers of the two adjacent tube bodies are in communication with each other, and a wall surface of each of the tube bodies has at least one connection port in communication with the first chamber. The adjustable valve is disposed in one of the tube bodies. The first chamber in each of the tube bodies is in communication with the second chamber in the tube body through the adjustable valve. In this way, the adjustable valve adjusts the flow rate of a cooling fluid flowing from the second chamber to the first chamber.Type: GrantFiled: November 16, 2011Date of Patent: February 18, 2014Assignee: Inventec CorporationInventors: Chien-An Chen, Wei-Ta Shih

Patent number: 8499791Abstract: A quick coupler has a coolant supplier seat and a transmission seat that can be optionally connected or disconnected. When the coolant supplier seat is connected to the transmission seat, the coolant can flow automatically from the coolant supplier seat to the transmission seat, so as to cool down electronic components inside a rack. When the coolant supplier seat is disconnected from the transmission seat, the coolant instantly stops flowing into the transmission seat. Because of the quick coupler, the rack installed inside a narrow space is convenient to set up or disassemble.Type: GrantFiled: January 28, 2011Date of Patent: August 6, 2013Assignee: Inventec CorporationInventors: Chien-An Chen, Wei-Ta Shih

Patent number: 8499790Abstract: An adjustable coolant quick coupler has a coolant supplier seat and a transmission seat that can be optionally connected or disconnected. The coolant supplier seat has a regulator assembly. The regulator assembly is able to adjust quantity of flow-in coolant and quantity of flow-out coolant. When the coolant supplier seat is connected to the transmission seat, the coolant can flow automatically from the coolant supplier seat to the transmission seat, so as to cool down electronic components inside a rack. When the coolant supplier seat is disconnected from the transmission seat, the coolant instantly stops flowing into the transmission seat. Because of the quick coupler, the rack installed inside a narrow space is convenient to set up or disassemble. Furthermore, by adjusting the quantity of flow-in coolant and the quantity of flow-out coolant, the electronic components can have a better effect of heat-dissipation.Type: GrantFiled: April 6, 2011Date of Patent: August 6, 2013Assignee: Inventec CorporationInventors: Chien-An Chen, Wei-Ta Shih
