Abstract: A method includes generating a plurality of beams that each illuminate a separate portion of a spatial light modulator. The spatial light modulator has a first dimension of a first length and a second dimension of a second length. Each of the beams spans a portion of the first length of the first dimension and a portion of the second length of the second dimension. The method also includes scrolling the plurality of beams along the second dimension of the spatial light modulator while maintaining at least a first gap between each of the plurality of beams.

Abstract: In one embodiment, a method includes transmitting one or more light beams by a first portion of a light modulator formed outwardly from a substrate. The one or more transmitted light beams are spatially integrated. A second portion of the light modulator is formed outwardly from the substrate. The second portion of the light modulator spatially integrates the transmitted light beams.

Abstract: A pulverizer 60 includes a spring assembly 10 that urges a grinding roller 72 of a journal assembly 68 onto a grinding surface 66 of a grinding table 64. The force applied is monitored by a load cell 32 located within spring assembly 10 that creates an electronic signal. A controller 83 receives the electronic signal and stores and/or displays it and alternatively acts to adjust the applied force to a desired value. Alternatively, adjustable forces or mechanical dampening may be applied to journal assembly 68 by controller 83. Alternatively, additional sensors may measure displacement of the journal assembly and rotation of the grinding table for other calculations.

Abstract: System and method for increasing display brightness in laser illuminated display systems. An illumination source includes a light source to produce light, a disk having a set of lens elements arranged in a circular ring around a center of the disk, a motor coupled to the disk, and an external lens positioned in a light path of the coherent light source. As the disk rotates, the lens elements are moved sequentially through the light, angularly deflecting the light, which may be corrected by the external lens into a spatial deflection. The spatially deflected light may be used to simultaneously illuminate a surface with more than one color of light, thereby increasing the brightness of the light source.

Abstract: A primary classifier (300) particularly suited for use in a bowl mill (10) of the type that is employed for purposes of effecting the pulverization of materials such as coal is provided by the present invention. The primary classifier (300) includes a vane wheel portion (360) affixed to the periphery of the rotatable grinding surface (14) of the bowl mill (10) so as to extend circumferentially around the entire interior of the substantially closed separator body (12) of the bowl mill (10). The primary classifier (300) further includes a low profile deflector portion (380) mounted within the interior of the substantially closed separator body (12) of the bowl mill (10) in closely spaced relation to the circumference of the rotatable grinding surface (14) at an elevation below the elevation of the grinding journal openings (205) and so as to extend continuously without interruption about the entire interior of the substantially closed separator body (12) of the bowl mill (10).
