Patent number: 8218335Abstract: A clip for securing a component, such as a circuit board, within a communications module is disclosed. The clip may include a flat base with legs extending therefrom and resilient springs disposed at terminal ends of each of the legs. The legs may be configured to frictionally secure the clip to the module. For instance, the legs may secure the clip to a top shell portion of the module. The springs may be configured to resiliently compress against corresponding contact zones on the circuit board when the top shell is mated with a bottom shell of the module such that the circuit board is secured in place within the module. Accordingly, embodiments of the invention enable the quick and simple assembly of modules without the need for fasteners and other time-consuming and/or labor-intensive solutions conventionally implemented to secure circuit boards and other components within the modules.Type: GrantFiled: July 8, 2008Date of Patent: July 10, 2012Assignee: Finisar CorporationInventors: Joshua Moore, Stephen Todd Nelson, Hung Van Nguyen

Patent number: 7954358Abstract: A method for a calibration module to calibrate laser bias current in an optical transceiver. The method comprises causing the calibration module to configure a control module of the optical transceiver for a calibration operation, causing the calibration module to determine a laser bias current monitored by the control module, and determining one or more calibration factor values that cause the laser bias current monitored by the control module to substantially match a laser bias current as measured by an external test meter.Type: GrantFiled: March 13, 2008Date of Patent: June 7, 2011Assignee: Finisar CorporationInventors: Victor Jacob Lerner, Jingyun Zou, Hung Van Nguyen, Charles Steven Joiner

Patent number: 7804362Abstract: A distributed amplifier may include an input transmission line for receiving on an input end an input signal, and an output transmission line for outputting on an output end an output signal. A plurality of amplifier stages may be coupled between intermediate positions on the input and output lines. Feedback impedance may negatively feed back a signal on the output end of the output line to a second end of the input line spaced from the first end of the input line.Type: GrantFiled: February 23, 2009Date of Patent: September 28, 2010Assignee: Microsemi CorporationInventor: Hung Van Nguyen

Patent number: 7762626Abstract: A spa chair having an apparatus for extending and retracting a tray from the spa chair is disclosed along with a method for utilizing the spa chair in one or more manicure and/or pedicure procedures. A pivoting mechanism coupled to the tray includes first attaching members for attaching the pivoting mechanism to the spa chair and a second attaching member for attaching the pivoting member to a tray. The pivoting mechanism also includes a shaft retained by the first attaching members and a spring for biasing a shaft and second attaching member in a particular direction. The pivoting mechanism is operable to lockingly secure the tray in at least one of an extended or retracted position.Type: GrantFiled: April 29, 2008Date of Patent: July 27, 2010Assignee: Beauty Mall Ltd.Inventors: Thanh Van Le, Hung Van Nguyen

Patent number: 7291272Abstract: A method is provided for removing an inorganic ionic species or organometallic ion contaminant, or combination contaminants, including such as arsenic, chromium, bromide, bromate, perchlorate, and/or others from water which contains an unacceptably high concentration of the contaminant(s). The method includes treating the water with an ion exchange resin, preferably a magnetic ion exchange resin such as MIEX® Resin, which is capable of adsorbing the inorganic ionic species contaminant(s), and regenerating and recycling the ion exchange resin back to the process. The method produces potable water from ground water containing such contaminants and eliminates breakthrough and chromatographic peaking problems observed with conventional ion exchange systems.Type: GrantFiled: May 6, 2005Date of Patent: November 6, 2007Assignee: Orica Australia Pty Ltd.Inventors: Michael Francis Bourke, Hung Van Nguyen

Publication number: 20040140266Abstract: The present invention relates to water treatment, in particular to a process for the removal of dissolved organic carbon from water. The process includes the following steps, adding an ion-exchange resin to water containing a contaminant such as dissolved organic carbon, dispersing the resin in the contaminated water to enable adsorption of the dissolved organic carbon onto the resin, and separating the resin loaded with contaminant from the water. In a preferred embodiment the process employs a magnetic ion-exchange resin.Type: ApplicationFiled: November 17, 2003Publication date: July 22, 2004Inventors: Hung Van Nguyen, Donald Bruce Bursill, James Young Morran, Mary Drikas, Veronica Laurel Pearce
