Abstract
Apparatuses and methods to detect and emit various infrared (IR) and ambient light signals using an integrated sensor and emitter device. Embodiments include a sensor to sense proximity, to sense IR data signals, and to sense ambient light; and an emitter of an IR proximity signal. The sensor detects the IR proximity signal from the emitter when the apparatus is sensing proximity, detects IR data signals when the apparatus is detecting IR data, and detects ambient light when the apparatus sensing light. The IR data signals may include IR remote control (IR RC) and/or IR data association (IRDA) signals. The signals may be detected simultaneously and may be in different frequency bands. According to embodiments, such an emitter may also emit an IR data signals, such as IR RC and/or IRDA signals. These signals may be emitted simultaneously and may be in different frequency bands.
