Patent number: 8432981Abstract: Various techniques are provided to detect a state of a communication signal. In one example, a method of detecting a state of a signal includes receiving a differential communication signal comprising a positive portion and a complementary negative portion. The method also includes generating a common mode voltage signal from the positive portion and the negative portion of the communication signal. The method also includes rectifying the positive portion and the negative portion of the communication signal to provide a rectified signal. The method also includes comparing the common mode voltage, signal with the rectified signal. The method also includes generating a high frequency detect signal in response to the comparing. The method also includes determining whether the communication signal is in an idle state or a high frequency state based on the high frequency detect signal.Type: GrantFiled: March 10, 2010Date of Patent: April 30, 2013Assignee: SMSC Holdings S.A.R.L.Inventors: Hongming An, Wei Fu, CongQing Xiong, James Ho

Patent number: 7834672Abstract: A charge pump is configured to control current flow at an output node in response to input signals. A plurality of control signals are generated based upon the input signals. The control signals operate to control the timing and duration of current flows within the charge pump and to thereby reduce charge pump power consumption. Based upon the control signals, the conductivity of a first path between a power supply and the output node and a second path between the output node and a ground potential is varied. Optionally, the charge pump is disposed as part of a phase-locked loop (PLL), the input signals are produced by a phase/frequency detector, and current flow at the output node controls an oscillator element.Type: GrantFiled: February 10, 2007Date of Patent: November 16, 2010Assignee: Exar CorporationInventors: Christopher G.

Publication number: 20060227822Abstract: A technique for compensating for the effects of thermo-optic distortions in a solid state laser gain medium, and reducing optical path differences in the laser. A diode array coupled to the laser gain medium is selectively modulated to provide pump power, the intensity of which varies across the aperture of the gain medium. The modulated diode array has a spatial power profile that is selected to compensate for thermal distortions arising from various causes. The modulated diode array may be one of several diode arrays providing pump power to the laser gain medium, or may be an auxiliary diode array with the sole purpose of providing compensating power input with a selected profile across the aperture of the gain medium.Type: ApplicationFiled: March 29, 2005Publication date: October 12, 2006Inventors: Gregory Goodno, Paul Epp, James Ho

Patent number: 6581305Abstract: The present invention is directed to a footwear construction having an insert of unitary structure and made of a single flexible material for providing increased structural support and strength of the footwear while maintaining flexibility of the footwear. Unlike the prior art insert, the present invention makes use of only a single material is used to manufacture the insert. A preferred material should be pliant or flexible and yet can provide the strength and structural support to the footwear in which the insert is used. Instead of using materials of different softness for the various sections in the insert to facilitate bending of the footwear, openings are added to various locations in the insert to facilitate planar bending movement. Such openings are commonly located in the forefoot section. To increase structural support and strength to the footwear, the insert is fixedly secured to the footwear.Type: GrantFiled: February 5, 2001Date of Patent: June 24, 2003Assignee: Odyssey Shoes, Inc.Inventor: James Ho
