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 |

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 |

20150257021 | System, Device And Method For Testing App Performance - An automated solution for measuring the performance of one or more selected apps across a wireless network, from a given location. The device of the invention, which may be termed a ‘probe’, performs the automation and validation of a range of apps with their respective cloud services, the probe including a local interface for receiving from a remote controller the credentials intended for testing the target app service if applicable. The invention can be used to generate an alert when the performance of a particular app at the location fails to meet certain criteria. It can also be sued to generate a report relating to the app performance at the location. | 09-10-2015 |

20130055732 | ICE MAKING SYSTEM USING DE-GASSED WATER - An improved system for making ice for recreational use. The system using water de-gassed by double filtration. The de-gassed water removes the insulator factor from ice that causes ice dehydration, makes it possible to operate with ice at a temperature 2-3° F. above that of existing recreational ice facilities while maintaining a high quality sheet of ice, produces an ice that is denser, more resilient to cuts and ruts and produces less snow development, all while lowering your energy consumption, permits ice to freeze faster and shows all painted lines and logos in the ice with greater clarity, and reduces carbon footprint, and benefits from decreased labour and refrigeration costs. | 03-07-2013 |
