20080279298	MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) DETECTOR INCORPORATING EFFICIENT SIGNAL POINT SEARCH - A novel and useful apparatus for and method of multiple input multiple output (MIMO) detection for use in MIMO based communication systems. The mechanism of the invention performs a simplified tree search utilizing a single stage expansion of the most likely first symbol candidates, in the case of a 2×2 MIMO system. The invention also provides a refinement mechanism that is operative to significantly improve the log likelihood (LLR) of the list of candidates. To improve the LLR, the mechanism applies refinements rounds to generate additional candidates for both first and second detected symbols.	11-13-2008
20080279299	MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) DETECTOR INCORPORATING EFFICIENT SIGNAL POINT SEARCH AND SOFT INFORMATION REFINEMENT - A novel and useful apparatus for and method of multiple input multiple output (MIMO) detection for use in MIMO based communication systems. The mechanism of the invention performs a simplified tree search utilizing a single stage expansion of the most likely first symbol candidates, in the case of a 2×2 MIMO system. The invention also provides a refinement mechanism that is operative to significantly improve the soft information (i.e. log likelihood ratio) of the list of candidates. To improve the soft information, the mechanism applies one or more refinements rounds to generate additional candidates for both first and second detected symbols.	11-13-2008

20110035256	Systems and methods for prioritized selection of media properties for providing user profile information used in advertising - Providing collected profiles by selecting one or more media properties and providing to each selected media property at least one profile attribute in a manner sufficient to enable the selected media property to electronically associate the provided profile attribute with the electronic visitor. Selected media properties can be a subset of one or more identified media properties. The media properties are selected or identified automatically, responsive to receiving current profile information about the visitor, among a multitude of media properties, based on a comparison of current and/or previous profile information received with previously received individualized requests for specific profiles, kinds of profiles, or profiles having specific attributes of interest to each of the media properties. A media property can be selected among those identified based on a media property selection history.	02-10-2011
