Patent number: 9089849Abstract: A single-region-board type high temperature electrostatic dust collector comprising anode boards (1), a cathode board (2), emitting electrodes (3) and a high voltage power supply is provided. Two parallel corrosion resistant plates are grounded to form the anode boards (1). One corrosion resistant plate with the same shape and size as the anode boards (1) connects to the cathode of the high voltage power supply, so as to form the cathode board (2), which are suspended between the two anode boards (1) and parallel with the anode boards (1). The disk-shaped emitting electrodes (3) are uniformly embedded at two sides of the cathode board (2).Type: GrantFiled: October 29, 2010Date of Patent: July 28, 2015Assignee: NANJING NORMAL UNIVERSITYInventors: Zhongzhu Gu, Jinjin Xu, Liying Dong, Juanjuan Liu

Patent number: 8836241Abstract: A driving controller for driving a load is disclosed. The driving circuit includes a driving power supply and the driving controller. The driving power supply provides a first power source to the load. The controller is coupled to a second power source to receive an electric power for operating. The controller controls the amount of the electric power to the load when operating in a first mode and stops the driving power supply from providing the electric power to the load when operating in a second mode. The controller operates exclusively in the first mode before the driving power supply provides the first power source to the load.Type: GrantFiled: January 9, 2013Date of Patent: September 16, 2014Assignee: Green Solution Technology Co., Ltd.Inventors: Shian-Sung Shiu, JuanJuan Liu

Patent number: 8755810Abstract: The present invention discloses a method and apparatus for rank self-adaptation. The method comprises: a base station receiving ranks reported by a user equipment via a rank receiving window, determining a rank at the current moment based on a distribution state of each rank in the rank receiving window at the current moment, and determining the number of independent channels used for sending downstream data to the user equipment based on the rank at the current moment. The present invention can reasonably forecast change of ranks of MIMO channels so as to better use MIMO channel resources to perform data transmission and improve the throughput rate of the MIMO channels.Type: GrantFiled: March 5, 2010Date of Patent: June 17, 2014Assignee: ZTE CorporationInventors: Yuanchun Tan, Focai Peng, Liping Liu, Xianxi Li, Juanjuan Liu, Liang Li

Patent number: 8461769Abstract: An LED driving circuit is used for dimming by switching between an operating current and a maintaining current or by voltage clamping of a source/drain of MOSFET that is coupled to the LED module. When the LED module is dimmed off, the voltage across the LED module can be kept at a value around a lighting threshold voltage of the LED module that is a minimum voltage for lighting the LED module. Therefore, a voltage difference between the drain and the source of MOSFET coupled to the LED module is smaller than that in the conventional arts. Hence, a withstand voltage of MOSFET can be reduced, and cost of the LED driving circuit as well as the power consumption of MOSFET can be lessened, thereby improving integral efficiency of the circuit.Type: GrantFiled: June 30, 2009Date of Patent: June 11, 2013Assignee: Green Solution Technology Co., Ltd.Inventors: Shian-Sung Shiu, Chung-Che Yu, JuanJuan Liu

Patent number: 8058818Abstract: An LED driving circuit and a MOSFET switch module thereof is disclosed, and the MOSFET switch module which is used to control a current of the LED driving circuit. The present invention employs a voltage clamping device to clamp the voltage level of the drain of transistor in the MOSFET switch module when being turned off. Via this way, the requirement for the withstand voltage of the transistor is lowered, and so the cost and power consumption thereof is reduced.Type: GrantFiled: March 16, 2009Date of Patent: November 15, 2011Assignee: Green Solution Technology Co., Ltd.Inventors: Shian-Sung Shiu, Chung-Che Yu, Juanjuan Liu
