20200382903 | SYSTEM AND METHOD FOR NAVIGATION AND GEOLOCATION IN GPS-DENIED ENVIRONMENTS - A threat warning system and method for navigation and geolocation in Global Positioning System (GPS)-denied environments using the threat warning system is disclosed. A threat warning system carried on a platform is provided. The threat warning system includes at least one detector, at least one threat warning image sensor, at least one processor, Global Positioning System (GPS) detection logic, last known position data logic, registration logic, navigation solution logic, position correction logic, and guiding logic. | 2020-12-03 |
20200382904 | Peer-to-peer geolocation system - A method and apparatus for location sharing, consisting of sending a location report by a location determining device to a plurality of network enabled devices over a peer-to-peer network, the location determining device being associated with a first digital key pair. A first of the plurality of network enabled devices, associated with a second digital key pair, performs a validation computation on the location report and submits a validation computation result and the location report to a remainder of the plurality of network enabled devices for inclusion in a shared ledger. Including the location report creates commercially-valued credits associated with the public key of the second digital key pair recorded in the shared ledger. A transfer of commercially-valued credits from association with the first public key of the first digital key pair to the public key of the second digital key pair is also recorded in the shared ledger. | 2020-12-03 |
20200382905 | WEARABLE DEVICE LOCATION ACCURACY SYSTEMS - Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. One embodiment involves pairing a client device with a wearable device, capturing a first client location fix at a first time using the first application and location circuitry of the client device. The client device then receives content from the wearable device, where the content is associated with a content capture time and location state data. The client device then updates a location based on the available data to reconcile the different sets of location data. In some embodiments, additional sensor data, such as data from an accelerometer, is used is used to determine which location data is more accurate for certain content. | 2020-12-03 |
20200382906 | METHOD FOR MANAGING WIRELESS SYSTEM AREA, TERMINAL AND BASE STATION - A method for managing a wireless system area, a terminal and a base station are provided. A new location management area for the terminal in an inactive connection state/RRC idle state is defined. The process of moving among different nodes in the area is simplified. | 2020-12-03 |
