摘要： This disclosure provides methods and apparatus for increasing the efficiency of a photovoltaic module. In one aspect, the position of a photovoltaic panel can be updated throughout the day based on whether the solar angle of incidence on the panel falls within a cone of at least 10° about a normal of the panel. For example, the panel can remain stationary when the solar angle of incidence falls within the cone, but when the solar angle of incidence falls outside the cone, the panel can be moved so that the solar angle of incidence falls within the cone.

摘要： This disclosure provides methods and apparatus for increasing the efficiency of a photovoltaic module. In one aspect, an apparatus includes an array of photovoltaic cells. One or more reflective surfaces can be provided along the edges of the array, between the edges of the array and the frame. The reflective surfaces can extend in a direction from the back of the array toward the front of the array so as to reflect light exiting the first and second edges of the array back into the array through the first and second edges. The reflective surface can be convex and/or can be disposed at one or more angles with respect to the array. The angles can be selected based on a selected geographical latitude and a corresponding selected orientation of the array relative to the sun.

摘要： Embodiments of MEMS devices comprise a conductive movable layer spaced apart from a conductive fixed layer by a gap, and supported by rigid support structures, or rivets, overlying depressions in the conductive movable layer, or by posts underlying depressions in the conductive movable layer. In certain embodiments, both rivets and posts may be used. In certain embodiments, these support structures are formed from rigid inorganic materials, such as metals or oxides. In certain embodiments, etch barriers may also be deposited to facilitate the use of materials in the formation of support structures which are not selectively etchable with respect to other components within the MEMS device.

摘要： This disclosure provides systems, methods and apparatus for an imaging system that includes a light guide having light-turning features that are configured to receive ambient light incident on the light guide, including light scattered from a scene to be imaged, and to direct the received ambient light towards an image sensor. The light-turning features may have angle-discriminating properties so that some light-turning features capture light incident upon the light guide at certain angles of incidence, but not others. Light scattered from multiple parts of a scene to be imaged may then be directed to correlated locations on an image sensor, which provides electronic data representing an image.

摘要： The efficiency of an etching process may be increased in various ways, and the cost of an etching process may be decreased. Unused etchant may be isolated and recirculated during the etching process. Etching byproducts may be collected and removed from the etching system during the etching process. Components of the etchant may be isolated and used to general additional etchant. Either or both of the etchant or the layers being etched may also be optimized for a particular etching process.

摘要： A system and method for processing video data are disclosed. In one aspect, a method includes generating halftone data for a first video frame and generating halftone data for a second video frame. The method further includes, to reduce at least one visual artifact, selectively copying the halftone data for the first video frame into the halftone data for the second video frame, the selective copying being based upon a comparison between a predetermined fixed threshold and the difference in the human visual system model-based perceptual error of the originally generated halftone data for the second video frame and the human visual system model-based perceptual error of the halftone data for the second video frame after the copying is done.
