O2Micro(R) Receives Patent for Inverter Circuits' Driving Techniques.SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif. & GEORGE TOWN, Grand Cayman -- O2Micro(R) International Limited (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :OIIM), a leading supplier of innovative power management, and security components and systems for the Computer, Consumer, Industrial, and Communications markets, was granted 4 claims under United States patent number 6,897,698 for its Phase Shifting and PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a (Pulse Width Modulation See PWM. ) Driving circuits and methods. This patented invention utilizes a phase shift technique to generate a plurality of switching drive signals for a DC/AC or DC/DC conversion application used in large and small LCD panel applications that include notebook computers, LCDM LCDM Lambda Cold Dark Matter LCDM Literature Culture and Digital Media (university courses) LCDM Large Component Development Management LCDM Life-Cycle Document Management (Liquid Crystal Display liquid crystal display (LCD) Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. Monitor), LCD TV, GPS (Global Positioning Satellite) and PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). (Personal Digital Assistant) applications. "The phase-shift technique provides a robust design for inverter (1) A logic gate that converts the input to the opposite state for output. If the input is true, the output is false, and vice versa. An inverter performs the Boolean logic NOT operation. (2) A circuit that converts DC current into AC current. Contrast with rectifier. applications. It improves the power conversion efficiency and supports various applications," commented Dr. Yung Lin, O2Micro's vice president of the Intelligent Lighting business unit.
