The case is Texas Advanced Optoelectronic Solutions Inc. v Intersil Corp., No. 4:08-CV-451. In 2002, TAOS patented its dual-diode ambient light sensor technology, which allows flat panel video displays to adjust brightness based on surrounding ambient The BiTec light sensor in the light meter incorporates the properties of a noise-free CMOS diode array and a silicon photodiode. It provides highly accurate spectral-radiometric and photometric measurement values by tweaking the measurement signals from With accuracy of ±10 per cent, the VCNL4040's built-in ambient light photo diode offers detection from 0.01lx to 5.2klx, allowing the device to operate in applications with dark or transparent window designs. The sensor offers fluorescent light flicker The VEML6070’s built-in photo-pin-diode offers spectral sensitivity from 280 nm to 400 nm, with a peak sensitivity wavelength of 355 nm. The sensor provides fluorescent light flicker immunity, a software shutdown mode to reduce power consumption to < 1 Mid-IR frequency combs are of widespread interest for gas sensing applications They placed a diode on the device that swept out built-up electrical charges so that the light source did not “feel” the few charges that were left. .
