20080222057 | METHOD AND APPARATUS FOR FUSING CONTEXT DATA - A system and method for fusing context data for use by context aware applications. The method includes the steps of receiving context data from a plurality of information sources; computing a quality measure for each input context value; organizing context values into one or more clusters, and assigning a single context value and a single quality measure to each cluster; and, selecting one or more clusters according to one or more criteria and aggregating the context values and quality measures of selected clusters to generate a single context value and quality single measure. The single context value and single quality measure are usable by a context aware application to avoid conflict and ambiguity among different information sources providing the context data. | 09-11-2008 |
20090209228 | SYSTEM AND METHOD FOR PROVIDING PERSONAL AND EMERGENCY SERVICE HAILING IN WIRELESS NETWORK - A method and system for providing personal and emergency service hailing. A profile database stores profiles with individualized distance thresholds for each of a number of wireless devices. A wireless message proximity request is received from a requesting wireless device. Distances between a location of the requesting wireless device and locations of each of other wireless communications devices is computed and compared to individualized distance thresholds stored for the requesting wireless communications device. A set of wireless devices consisting of wireless devices that satisfy the individualized distance thresholds for the requesting wireless communications device is identified and a wireless message proximity response is sent to the requesting wireless communications device. The wireless message proximity response identifies the set of wireless communications devices that satisfy the at least one individualized distance threshold. | 08-20-2009 |

20090190101 | Double-Reverse Total-Internal-Reflection-Prism Optical Engine - A device for a light projection system comprises at least one light source; light collection and relay optics; a reflective surface; a micro-display; an illumination total internal reflection TIR-prism disposed between the reflective surface and the micro-display; an imaging TIR-prism disposed between the illumination TIR-prism and the micro-display; and a projection lens. The light collection and relay optics is arranged to channel light emitted by the at least one light source to the illumination TIR-prism. The TIR-prism is arranged to totally internally reflect the light to the reflective surface. The reflective surface is arranged to reflect the light back through the illumination TIR-prism and through the imaging TIR-prism to the micro-display. The micro-display is arranged to reflect the light back through the imaging TIR-prism. The imaging TIR-prism is arranged to totally internally reflect the light from the micro-display to the projection lens. | 07-30-2009 |
20100232176 | Illuminator method and device - A first toroidal ray guide defines an axis of revolution and has a toroidal entrance pupil adapted to image light incident on the entrance pupil at an angle to the axis of revolution between 40 and 140 degrees, and it also has a first imaging surface opposite the entrance pupil. A second toroidal ray guide also defines the same axis of revolution and has a second imaging surface adjacent to the first imaging surface. Various additions and further qualities of the ray guides, which form optical channels, are disclosed. In a method light emanating from a source at between 40-140 degrees from an optical axis is received at an entrance pupil of a ray guide arrangement that is circularly symmetric about the optical axis. Then the received light is redirected through the ray guide arrangement to an exit pupil in an average direction substantially parallel to the optical axis. | 09-16-2010 |
