Abstract: A semiconductor device comprises an array of individually controllable image pixels arranged in a plurality of reset groups. Each of the image pixels in the array of individually controllable image pixels has a one-to-one correspondence with at least one memory cell in an array of memory cells. The semiconductor device further comprises a plurality of sub-pixel sets, wherein each sub-pixel in the plurality of sub-pixel sets is a micromirror, and wherein each of the image pixels comprises a sub-pixel set.

Abstract: Disclosed embodiments comprise dynamic pulse width modulation (PWM) bit sequence selection techniques for use with video display devices. By dynamically selecting and applying a bit sequence based on the display image content and the limited dynamic range of human perception, the bit sequence used to display a given scene may be optimized in order to provide for increased bit depth or increased brightness. Generally one out of a plurality of available bit sequences would be applied to a given scene, with different bit sequences designated for displaying bright scenes and dark scenes. Alternatively, different bit sequences may be applied depending upon the amount of motion in a scene. Thus, a dynamic bit sequence selection technique may allow for a display device with increased bit depth and increased brightness.

Abstract: The invention provides apparatus and systems for cabinet receptacles, including a horizontally swingable door and an interior floor with a receptacle support affixed to the inside surface of the door and a receptacle retained on the receptacle support in a position adjacent to the inside surface of the door. One or more wheels attached to the receptacle support engage the cabinet floor for substantially bearing the weight of the receptacle.

Abstract: A method of loading data into a spatial light modulator, in which a software programmable processor stores binary values for the pixels of at least a portion of the (x,y) array of a spatial light modulator. The processor stores these values in its addressable memory, and accesses them by calculating bit positions in memory words (elements), as a function of x and y and other parameters of the processor and spatial light modulator. The same concepts may be applied to reading data out of a spatial light modulator.
