20090210156 | EFFICIENT USE OF EXPECTED USER ALTITUDE DATA TO AID IN DETERMINING A POSITION OF A MOBILE STATION - A method and apparatus for using a predetermined portion of terrain elevation maps in a database for aiding in computing a three-dimensional position of a wireless station. Instead of using the entire terrain model of the earth or an entire country, the database consists of an incomplete model, which includes only the most populous areas or specific regions. This reduces the size of the information in the database, which in turn reduces the amount of time to compute the positions of the wireless device. | 08-20-2009 |
20090310593 | SELF-POSITIONING ACCESS POINTS - A system, method and apparatus are provided which relate to calibrating a wireless access point so as to allow proper synchronization of mobile wireless devices connecting to the wireless access point. A closed-loop filter is used to more accurately synchronize times and to more accurately determine the location of the access point for purposes of determining the position of a mobile station. | 12-17-2009 |
20100309044 | On Demand Positioning - The subject matter disclosed herein relates to determining a location of a mobile device using more than one location-determining technology. | 12-09-2010 |
20100330940 | SENSOR-AIDED WIRELESS COMBINING - An apparatus and method are disclosed for achieving receiver diversity. A wireless unit includes a plurality of antennas, an antenna selector to select one or more antennas from the plurality of antennas, a processor with input data from an inertial sensor for monitoring the orientation of the wireless unit. Based on the input data, the processor commands the antenna selector to select one or more antennas. In some embodiments, the processor is a diversity processor. Based on the input data from the inertial sensor, the diversity processor computes the combination of the received signals. In another aspect, the wireless unit further includes a baseband processor to process the output of the diversity processor for a particular unit application. | 12-30-2010 |
20110257885 | METHOD AND APPARATUS FOR GEOGRAPHICALLY AIDING NAVIGATION SATELLITE SYSTEM SOLUTION - The present invention is related to position calculation and navigation systems, and more particularly, to a method and apparatus for making accuracy improvements to a GPS receiver's navigation solutions. According to a first aspect, selective cartography information from a map database accessed by a GPS receiver from a location-aiding device is integrated into the position calculations performed by the GPS receiver. According to another aspect, selective cartography information includes indices representing associated attributes of geographical objects, such as, a width-indicator index for a road segment. | 10-20-2011 |
20130090134 | Method and apparatus for power efficient user location profile determination in mobile devices - Systems and methods are disclosed for reducing power consumption of a mobile device in determining locations by determining if the mobile device is stationary; and if the mobile device is stationary, determining if the mobile device is in a zone with a known location and assign the known location as the location of the mobile device without involving a position determination system in the mobile device to reduce power consumption arising therefrom. | 04-11-2013 |
20130121194 | Method and apparatus for locally optimizing wireless operation in mobile devices - Location profile is used as a way of optimizing power consumption of communication devices such as mobile handsets and smart phones which tend to have facilities for multiple wireless methods for communication. This is done by correlating the availability of the wireless signals to the specific zones in the user location profile. The method learns the wireless environment of each zone and subsequently while the device is detected to be in the same zone, intelligently prioritizes use of different communication methods for that zone, and turns off all unnecessary communication options, thereby reducing power consumption. | 05-16-2013 |
20130147663 | On Demand Positioning - The subject matter disclosed herein relates to determining a location of a mobile device using more than one location-determining technology. | 06-13-2013 |
20140210662 | Demand Positioning - The subject matter disclosed herein relates to determining a location of a mobile device using more than one location-determining technology. | 07-31-2014 |
