20110248865 | SENSOR DEVICE WITH FLEXIBLE INTERFACE AND UPDATABLE INFORMATION STORE - A sensor device includes an interface that receives a request. The sensor device includes an updatable information store that responds to the request if the request is directed to the updatable information store, the updatable information store being in a first power domain of the sensor device. The sensor device also includes a power manager that activates a sensor element in the sensor device in response to receiving the request if the request is a request for measurement of a parameter by the sensor element. The sensor element is in a second power domain of the sensor device. The sensor element communicates measured parameter information to the updatable information store. | 10-13-2011 |
20120001841 | IDENTIFYING AMBIENT LIGHT TYPE AND ILLUMINANCE COMPENSATION USING A PLURALITY OF PHOTODETECTORS - A method for determining an ambient light type is described. The method includes receiving measurement information from multiple photodetectors configured for different light spectra, calculating a color ratio using the measurement information, obtaining a correction value using the color ratio, applying the correction value to at least one of the first and second measurement information to obtain a photopic illuminance value, and determining an ambient light type using the photopic illumination value and the color ratio. | 01-05-2012 |

20110248649 | SYSTEMS AND METHODS FOR A DIGITAL-TO-CHARGE CONVERTER (DQC) - Systems and methods for a digital-to-charge converter (“DQC”) are disclosed. A DQC may include a converting circuit configured to receive a first digital signal indicative of a voltage across a capacitor coupled to an output pin of the digital-to-charge converter and to determine a present charge of the capacitor based at least in part on the first digital signal. The DQC may also include an error determining circuit coupled to the converting circuit, wherein the error determining circuit is configured to receive a second digital signal indicative of a target charge via an input pin of the digital-to-charge converter and to determine a difference between the target charge and the present charge. The DQC may further include a correction circuit coupled to the error determining circuit and configured to control a programmable current source to produce an analog signal at the output pin in response to the determined difference. | 10-13-2011 |
20140374600 | Ultraviolet Sensor - An ultraviolet radiation sensor includes an ultraviolet pass filter. A first photodiode senses light passing through the ultraviolet pass filter and provides an indication of ultraviolet light. A second photodiode provides an indication of infrared radiation. A correction circuit corrects the indication of ultraviolet light sensed by the first photodiode using the indication of infrared to account for infrared radiation that passes through the ultraviolet pass filter. Additional photodiodes may be used to correct for leakage current in the first and second photodiodes and stray infrared radiation that may affect the output of the first and second photodiodes. | 12-25-2014 |
