20150141035 | METHOD AND APPARATUS FOR CLASSIFYING A MOBILE DEVICE LOCATION - Methods, apparatus, and computer program products for classifying a mobile device location are described. An example of a method for classifying the mobile device location includes mapping the mobile device location to a pixel address in a dilated test texture, wherein the dilated test texture corresponds to an uncertainty estimation associated with the mobile device location and determining an in-out classification of the mobile device location based on a query of a pixel value associated with the pixel address in the dilated test texture. | 05-21-2015 |
20150148057 | MOTION STATE BASED MOBILE DEVICE POSITIONING - Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device or one or more computing devices to provide for or otherwise support motion state based mobile device positioning. In an example, a method may be implemented at a mobile device to identify two or more subsets of grid points corresponding to an electronic map representing a particular environment, select one of the two or more subsets of grid points for use in position estimation based, at least in part, on a motion state of the mobile device, and determine an estimated position of the mobile device based, at least in part, on the selected subset of grid points. | 05-28-2015 |
20150161440 | METHOD AND APPARATUS FOR MAP ALIGNMENT IN A MULTI-LEVEL ENVIRONMENT/VENUE - Methods and devices are described for aligning map data from different levels of the same location/venue/environment. Certain embodiments may include receiving, at a computing device, first and second sets of map data associated with corresponding first and second levels of a location. The device may receive via a network or user interface, sets of anchor points matched across the different levels. These matched anchor points may then be used to deform one or more levels of map data to align any misaligned anchor points. | 06-11-2015 |
20150215731 | METHOD AND APPARATUS FOR HIERARCHICAL MAP TILING - A method for processing assistance data associated with positioning of a mobile device as described herein includes estimating an initial location of the mobile device within an area; designating the initial location of the mobile device as a focal point; retrieving a subset of hierarchical assistance data as a function of the focal point; and generating a multi-level assistance data structure for the area centered at the focal point. | 07-30-2015 |
20150226573 | PEDOMETER INTEGRATED PEDESTRIAN POSITIONING - An estimated position of a pedestrian is obtained by detecting, by a movement sensor on the pedestrian, whether the pedestrian is moving, propagating particles based on a predictive pedestrian movement model upon detecting that the pedestrian is moving, and updating, by a wireless network, the position of the pedestrian upon failure by the movement sensor to detect that the pedestrian is moving. The movement sensor may be a pedometer. The wireless network may be a local wireless network such as a Wi-Fi network. | 08-13-2015 |
20150228095 | Method and apparatus for generating a heatmap - Systems, apparatus and methods for generating a heatmap are presented. A first floor plan is received. A device detects stair lines in the first floor plan and reduces the stair lines from the first floor plan to form a second floor plan. A heatmap is generated based on the second floor plan. The device includes a transceiver to receive the first floor plan and a processor, coupled to the transceiver, to detect stair lines in the first floor plan, reduce the stair lines in the first floor plan to form a second floor plan, and generate the heatmap from the second floor plan. | 08-13-2015 |
20150237509 | CROWD SOURCING STRATEGY TO MINIMIZE SYSTEM BIAS - Systems, apparatus and methods for deriving a heatmap in a server are presented. A heatmap is formed from sensor measurements and/or wireless signal strength measurements that have been grouped. Sensor measurements are paired or group into complementary sets thereby reducing sensor bias and/or system bias that is otherwise included because of sensor drift and unbalanced directional travel. Similarly, wireless signal strength measurements are paired or group into complementary sets also reducing system bias. | 08-20-2015 |
20150296479 | SYSTEMS, APPARATUS, AND METHODS FOR LOCATION ESTIMATION OF A MOBILE DEVICE - Systems, apparatus, and methods for estimating the location of a wireless device include determining the location estimate based on accessible access points and without using a received signal strength indicator. In some embodiments, the location estimate is determined based on a center of mass of the accessible access points, a closest accessible access point, a center of mass of N access points, an average angle of the accessible access points, or a Parzen density of accessible access point distributions. | 10-15-2015 |
