Publication number: 20130207949Abstract: A method for adjusting brightness of a display device acquires optical signals from a plurality of light sensors positioned on the display device. The optical signals are converted into digital signals. An ambient brightness value is determined according to the digital signals. If the ambient brightness value is not less than a predetermined value, a calibration brightness value of the display device is calculated according to the ambient brightness value. If the calibration brightness value is equal to zero and the display device has received video signals during a predetermined time interval, a current brightness value of the display device is maintained. If the calibration brightness value is not equal to zero and the display device has received the video signals during the predetermined time interval, the current brightness value of the display device is adjusted according to the calibration brightness value.Type: ApplicationFiled: June 19, 2012Publication date: August 15, 2013Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD.Inventors: TIE-ZHENG JIANG, CHI-CHE CHEN

Publication number: 20100031206Abstract: Method and technique for analogue circuit synthesis. An analogue circuit usually includes many circuit components, and characteristics and functions of each circuit component are controlled by many corresponding parameters. In the presented invention, selected key design parameters of selected critical circuit components, as well as optimization targets, design specification or/and design constraint, are transformed into an optimization plan, and an optimization engine iterates circuit level or system level numerical simulations by changing values of the selected key design parameters recorded in the optimization plan, so as to find optimized parameters and circuit components which allow the analogue circuit to match the design specification/constraint and to approach the optimization target. Thus a systematic automation for analogue circuit synthesis/design/optimization is achieved.Type: ApplicationFiled: July 30, 2009Publication date: February 4, 2010Applicant: FARADAY TECHNOLOGY CORPORATIONInventors: Chang-Chung Wu, Chi-Che Chen, Jung-Chi Ho, Woei-Tzy Jong, Yeong-Jar Chang
