Abstract:
Electronic displays encounter visibility issues due to varying ambient light conditions. An ambient light sensor can be provided to sense ambient light and dynamically adjust display brightness to compensate for changes in ambient light. A wave guide for improving angular response in a light sensor is provided.

Abstract:
A solar sensor that utilizes a blocking element and curved reflective element between the sun and a photo-sensitive electronic device to provide high signal levels and the ability to shape the angular response of the overall sensor. A particular angular response can be achieved by combining the attenuating affects of the blocking element with the increased response affects of the curved reflector. These two elements may be combined into one physical structure, or may be separate. Further, the present invention contemplates the use of multiple blocking elements and multiple reflectors.
Abstract:
A UV exposure mointoring system for measuring UV radiation impinging on an object, the system comprising apparatus for measuring incident solar UV radiation in a weighted manner corresponding to the erythemal action spectrum of human skin, whereby the accuracy of the measurements is substantially unaffected by the amgle of incidence of incoming radiation over a wide range of angles.
