Abstract: A method and an ambient light color sensor adapted to determine color of ambient light comprising a memory, a processor, and a light color sensor with a plurality of channels that detect light at different wavelengths. Wherein the memory comprises a calibration matrix determined by calibrating a test light color sensing device under at least one ambient lighting condition, and a normalized gain value for each channel determined by calibrating the ambient light color sensing device to an artificial light source. Wherein the processor receives the sensor readings from the light color sensor, normalizes each received sensor reading using the normalized gain value of a respective channel, determines at least one measured light color value that quantifies color of light from the normalized sensor readings, and determines at least one calibrated light color value by correlating the at least one measured light color value through the calibration matrix.

Abstract: An ambient light color sensing device adapted to determine color of ambient light and method for calibrating thereof. The ambient light color sensing device comprises a memory, a processor, and a light color sensor having a plurality of channels that detect light at different wavelengths to produce sensor readings.

Abstract: An ambient light color sensor adapted to determine color of ambient light and method for calibrating thereof. The ambient light color sensor comprises a sensor body having at least one diffuser and a light color sensing module disposed below the at least one diffuser. The light color sensing module comprises a plurality of channels adapted to detect light collected by the at least one diffuser at different wavelengths to produce sensor readings.

Abstract: A color temperature sensor assembly comprising a sensor body, a substantially dome shaped diffuser extending through an opening in the sensor body, a substantially flat diffuser disposed within the sensor body below the first diffuser, and a color temperature sensing module disposed below the flat diffuser and adapted to detect a color temperature of light collected by the dome shaped diffuser and the flat diffuser. The shape of the dome diffuser helps capture light from all angles to bring in more light to the sensor and provide more accurate readings. The secondary flat diffuser is adapted to further diffuse the light to reduce light concentration and prevent inaccurate readings. The color temperature readings from the color temperature sensor assembly may be used to control at least one lighting load.

Abstract: A multi-user, multi-device remote access system is provided for allowing a plurality of non-homogenous, spatially-distributed devices, such as sensors, actuators, controllers, and other similar devices, to be remotely controlled by a user via a user interface. A universal controller allows devices of various types to be automatically integrated therewith for use. The universal controller communicates with a resource manager that monitors and dispatches requests for information and commands generated by the user at the user interface. High-level instructions are entered by a user at the user interface, received by the resource manager, and translated into bytecodes, whereupon the bytecodes are sent to an appropriate universal controller based upon instruction type and device availability. The bytecodes are executed by the universal controller, and one or more devices connected therewith are activated.
