Patent number: 8532147Abstract: A method and system are provided for preventing data loss in a VoIP system. In particular, during a VoIP call, it is determined whether incoming ringing on a POTS line causes an unacceptable level of signal loss or errors. If so, for subsequent VoIP calls, the CO handling calls to the POTS line is instructed to either answer each call with a busy signal or automatically forward calls to the POTS line to the VoIP line or other selected telephone. Calling returns to normal upon ending of the VoIP call. In this manner, incoming ringing on the POTS line does not result in call dropping or lengthy retraining processes.Type: GrantFiled: July 20, 2012Date of Patent: September 10, 2013Assignee: Conexant Systems, Inc.Inventors: William Scholtz, Ben Chan, Ehud Langberg, Shareq Rahman, Xy Chen, James Zhang

Publication number: 20110032849Abstract: Systems and methods which implement cooperative techniques at wireless network access points to provide interference mitigation are shown. Embodiments utilize cooperative antenna beam adaptation techniques wherein antenna beam selection, selective antenna beam transmission power, and/or antenna beam null selection is implemented based upon the communication environment created by a plurality of access points. Additionally or alternatively, embodiments utilize cooperative antenna beam isolation techniques wherein narrow channel filters are implemented with respect to antenna beam signals and/or shielding is provided between various antenna beams based upon the communication environment created by a plurality of access points.Type: ApplicationFiled: August 7, 2009Publication date: February 10, 2011Applicant: FiMax Technology LimitedInventors: Simon Yeung, Ben Chan, Jason Leung, Doug George, Piu Bill Wong

Publication number: 20070067034Abstract: An expandable stabilization device is disclosed that is suitable for deployment within cancellous bone, including, for example, within a vertebral body of a spine. The device comprises: an elongate expandable shaft adapted to be positioned within a vertebral body having a first profile and a second profile; wherein the shaft is adapted to cut through cancellous bone within the vertebral body during expansion from the first profile to the second profile; and further wherein the shaft is adapted to abut a surface of cortical bone within the vertebral body without passing therethrough. The invention also includes a method for treating cancellous bone, such as cancellous bone of a vertebral body.Type: ApplicationFiled: August 30, 2006Publication date: March 22, 2007Inventors: Paul Chirico, Ben Chan

Patent number: 6709930Abstract: A trench MOSFET is formed by creating a trench in a semiconductor substrate, then forming a barrier layer over a portion of the side wall of the trench. A thick insulating layer is deposited in the bottom of the trench. The barrier layer is selected such that the thick insulating layer deposits in the bottom of the trench at a faster rate than the thick insulating layer deposits on the barrier layer. Embodiments of the present invention avoid stress and reliability problems associated with thermal growth of insulating layers, and avoid problems with control of the shape and thickness of the thick insulating layer encountered when a thick insulating layer is deposited, then etched to the proper shape and thickness.Type: GrantFiled: June 21, 2002Date of Patent: March 23, 2004Assignee: Siliconix IncorporatedInventors: Ben Chan, Kam Hong Lui, Christiana Yue, Ronald Wong, David Chang, Frederick P. Giles, Kyle Terrill, Mohamed N. Darwish, Deva Pattanayak, Robert Q. Xu, Kuo-in Chen
