| 20100309058 | SYSTEM AND METHODS FOR DIRECTION FINDING USING A HANDHELD DEVICE - A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device. | 12-09-2010 |
| 20130162481 | SYSTEMS AND METHODS FOR CALIBRATION OF INDOOR GEOLOCATION - In a system facilitating the calibration of a map-point grid for an indoor location, the grid includes several map points, each having a radio frequency (RF) data fingerprint associated therewith. RF data are received from a device associated with a user, and a map point is identified or determined based on, at least in part, the received RF data. A reliability of a fingerprint to be associated with the map point is computed based on, at least in part, a comparison of a parameter associated with the map point with reference data associated with the indoor location such as topology of the location, and speed and orientation of the user. A fingerprint is associated with the first map point based on, at least in part, the first RF data and the computed reliability. The computation of the reliability may also be based on additional RF data and location determination based thereon and/or user feedback. An existing fingerprint may be adjusted based on the received RF data. | 06-27-2013 |
| 20150061938 | USING INERTIAL NAVIGATION FOR CALIBRATION OF INDOOR POSITIONING SYSTEM - A method and apparatus for using inertial navigation for obtaining calibration data for an indoor positioning system are disclosed. In one embodiment, the method comprises tracking motion of a device between known locations within a structure using inertial navigation, collecting a plurality of Wi-Fi signatures with the device while tracking the motion of the device between the known locations, and matching each of the plurality of Wi-Fi signatures to a point between the known locations, where the matched Wi-Fi signatures are for use in comparing to Wi-Fi signatures being received by the indoor positioning system to identify an indoor location of a device within the structure. | 03-05-2015 |
| 20150138019 | METHOD AND APPARATUS FOR TRANSMITTING INDOOR CONTEXT INFORMATION - The subject matter disclosed herein relates to a system and method for determining indoor context information relating to a location of a mobile device. Indoor context information may be utilized by a mobile device or a network element to obtain an estimate of a location of the mobile device within an indoor environment. | 05-21-2015 |
| 20150309158 | SYSTEM FOR PRECISELY LOCATING AN ASSET POINT IN A PHYSICAL PLANT - A system for precisely locating an asset or measurement point in a physical plant is provided. The system includes a wireless mesh formed by a plurality of transmitters located at known locations disposed throughout the physical plant and a hand held device having an application disposed thereon enabled to triangulate to a precise location in the physical plant by the wireless mesh. The precise location is then overlaid on an asset map displayed on the hand held device having the application. Therefore, knowing the location on the asset map permits the hand held device to precisely display both the particular asset and the particular assets location. | 10-29-2015 |
| 20150309159 | METHOD OF OPERATING A SYSTEM FOR PRECISELY LOCATING AN ASSET POINT IN A PHYSICAL PLANT - A method of operating a system for precisely locating an asset or measurement point in a physical plant is provided. The steps of operating the system include providing a hand held device having an application disposed thereon; forming a wireless mesh with a plurality of transmitters located at known locations disposed throughout the physical plant; enabling the hand held device to triangulate to a precise location in the physical plant by virtue of the application and wireless mesh; overlaying the precise triangulated location on an asset map displayed on the hand held device, and displaying accurately both the particular asset and particular assets location by knowing its precise location overlaid onto the asset map. | 10-29-2015 |
