| 20080204546 | Stereoscopic Imaging Device and Means for Construction Thereof - A stereoscopic display device comprises a display device for displaying a pixellated display image; and a stereoscopic conversion screen. The conversion screen comprises an array of light guiding members, each light guiding member being associated with an underlying pixel or sub-array of pixels, and wherein alternate rows of light guiding members are arranged to direct light from the associated pixel or sub-array of pixels to different viewing positions. The invention provides spatial multiplexing of images into successive horizontal rows, rather than in vertical columns, as in common practice. This can resolve a looming problem so that a stereoscopic effect is perceived across the full width of the 2D image. This spatial multiplexing screen may be combined with a dynamic temporal multiplexing arrangement to increase the number of views. The invention also relates to such a dynamic temporal multiplexing system. The display device may be switchable between 2D and 3D modes of operation by using electro chromic materials, or by removing the conversion screen. | 08-28-2008 |

| 20090281206 | COPOLYMER POLYOLS AND A PROCESS FOR THE PRODUCTION THEREOF - The present inventions disclosed copolymer polyol composition which have a polymer content of 40 to 75 weight percent, based on total weight, and product stability such that essentially 100 percent passes through a 150 mesh screen produced by a free radical polymerization of the composition comprising: (a) a feedstock polyol; (b) at least one ethylenically unsaturated monomer; (c) a free radical polymerization initiator; (d) a chain transfer agent; (e) optionally a preformed stabilizer; and (f) optionally a macromer; with the proviso that at least one of e) or f) is present; wherein the feedstock has a nominal average functionality of 1.5 to 2.7, an equivalent weight of 400 to 2000. Such copolymer polyols can be used for the production of polyurethane products. | 11-12-2009 |

| 20100251512 | CONTROL OF AN ELECTRIC MACHINE - A method of controlling an electric machine that includes exciting a winding of the electric machine in synchrony with zero-crossings of back emf when operating over a first speed range. The method then includes exciting the winding in advance of the zero-crossings by a fixed period of time when operating over a second speed range, and exciting the winding in advance of the zero-crossings by a period of time that varies with speed when operating over a third speed range. Additionally, a control system for an electric machine, and a product incorporating the control system and electric machine. | 10-07-2010 |
