20100311343 | HIERARCHICAL MODULATION FOR ACCURATE CHANNEL SOUNDING - Method and apparatus for improving the channel estimate of a communication channel between a first station and a second station, while reducing the amount of reserved bandwidth for pilot tones. Hierarchical modulation is used to augment pilot density without sacrificing throughput. At the first station, a digital information stream may be split into a base stream and an enhancement stream, wherein the base stream and the enhancement stream combined form a hierarchical signal. At the second station, the base stream may be first recovered, and recovered base stream serves as a pilot for the enhancement stream. Thus the base stream, which is a subset of the total transmitted information, may be made to perform the channel-sounding function for the enhancement stream. | 12-09-2010 |
20110045768 | CREATION OF A BEAM USING ANTENNAS - Method and apparatus for creating a pencil beam using a plurality of small diameter dish antennas. A plurality of small diameter dish antennas are spatially arranged and driven by varying electronic signals in such a way that the plurality of small diameter dish antennas co-operatively produce a pencil beam in the direction of a distant object. | 02-24-2011 |
20120232796 | COMPUTING PATHS BETWEEN GEOGRAPHICAL LOCALITIES - Technology is generally described for computing paths between geographical localities. The technology can receive a request for a path between two or more geographical localities, and compute a path based at least on a popularity rating of intermediate geographical localities. | 09-13-2012 |
20130046706 | ANALYZING COMMUNICATIONS TO DETERMINE BUSINESS ENTITY POPULARITY - Techniques for determining the popularity of a business entity are provided. A communication is received at a computing system. The computing system searches the received communication for a business entity name. The computing system also searches the received communication for information related to an opinion about the business entity. Based on the information related to the opinion, the computing system determines a customer satisfaction rating of the business entity. | 02-21-2013 |
20130102332 | CHANGING THE ORIENTATION OF A USER BASED AT LEAST IN PART ON TRANSMIT POWER - Implementations and techniques for changing the orientation of a user of a mobile communication device based at least in part on transmit power are generally discussed. The change in orientation of the user may reduce radiation absorbed by the user. | 04-25-2013 |
20130226456 | COMPUTING PATHS BETWEEN GEOGRAPHICAL LOCALITIES - Technology is generally described for computing paths between geographical localities. The technology can receive a request for a path between two or more geographical localities, and compute a path based at least on a popularity rating of intermediate geographical localities. | 08-29-2013 |
20130244689 | DETERMINING THE POSITION OF A MOBILE DEVICE IN AN INDOOR ENVIRONMENT - Technologies and implementations for determining the location of a device in an indoor environment are generally disclosed. | 09-19-2013 |
20130311090 | COMPUTING PATHS BETWEEN GEOGRAPHICAL LOCALITIES - Technology is generally described for computing paths between geographical localities. In some examples, the technology can receive a request for a path between two or more geographical localities, and compute a path based at least on a popularity rating of intermediate geographical localities. | 11-21-2013 |
