An electronic device may include an infrared sensor, an ambient light sensor, a decoder, and a processor. The infrared sensor may detect an intensity of infrared light. The ambient light sensor may be configured to detect incident light and to generate an electronic signal indicative of an intensity of visible light. The decoder may be configured to receive the intensity of infrared light and to generate an intensity of decoded infrared light. The processor, which may be coupled to the decoder and the ambient light sensor, may be configured to substitute an alternate electronic signal for the electronic signal if the intensity of infrared light exceeds a threshold amount.

Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: A light sensing circuit, a method of controlling the same, and a touch panel including the light sensing circuit. In the method of controlling the light sensing circuit, including sensing light incident on a photodiode, generating current corresponding to the brightness of the sensed light, amplifying the current using a driving transistor, and outputting the amplified current, the ambient temperature is sensed, and a time period during which the light is sensed by the photodiode or the amplified current is output is controlled by the sensed ambient temperature. Thus, the sensitivity of the light sensing circuit may be constantly maintained without being influenced by the ambient temperature.

Abstract: Light sensors (1) are used in lighting applications, especially in combination with LEDs, to control and/or adapt the color point of light sources. Costs and/or performance of the light sensor (1) are essential in order to guarantee cost-effective light sources with reproducible color points.

The light diffuser (10) is arranged in such a way that light from outside the optical non-transparent housing (11) has to pass the light diffuser (10) so as to enter the interior of the optical non-transparent housing (11) via the window (12). The interference filter (13) and the at least two photo sensors (14) are arranged in the interior of the optical non-transparent housing (11), which interference filter (13) is arranged between the window (12) and the at least two photo sensors (14).
