Proximity, Ambient Light Sensors Integrated in One Chip. Capella Microsystems Inc of Taiwan developed the CM3612, a chip integrating an infrared proximity sensor and an ambient light sensor, which can detect the brightness of the surrounding environment. The proximity sensor determines whether the display on a mobile device is in use and turns it off when it is not used. The ambient light sensor automatically adjusts the luminance of the display in accordance with the brightness of the surrounding environment. With these power saving features, the chip can extend the life of batteries in display-equipped devices, such as mobile phones and notebook computers, the company said ...
