[February 26, 2013] O2Micro International Assigned Patent Tweet (Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., Feb. 26 -- O2Micro International, Grand Cayman, Cayman Islands, has been assigned a patent (8,376,611) developed by Guoxing Li, Sunnyvale, Calif., and Xiaohu Tang, Shanghai, China, for "circuits and methods for temperature detection." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A temperature detection circuit includes a sensor, an integrated circuit (IC) chip, and a resistor. The sensor is operable for sensing a temperature. The IC chip can compare a sense voltage indicative of the temperature with a threshold voltage indicative of a temperature threshold to determine a temperature condition. The IC chip has a substantially constant parameter. The resistor is externally coupled to the IC chip. The IC chip maintains a current ratio, including a ratio of a first current flowing through the sensor to a second current flowing through the resistor, equal to the substantially constant parameter." The patent application was filed on March 31, 2010 (12/751,432).
