| 20120173139 | POSITION ESTIMATION FOR NAVIGATION DEVICES - A method of providing position estimation with a navigation device comprises periodically recording magnetic field strength of an area substantially surrounding a navigation device as a user of the navigation device traverses a select pathway. The method combines the recorded magnetic field strength with measurements from at least a dead reckoning portion of the navigation device to provide position estimates along the select pathway. The method further corrects each of the position estimates from a starting position on the select pathway, where each of the corrected position estimates have an error value below one or more previous position estimates and any intervening positions between each of the one or more previous position estimates and the starting position, with the error value corresponding to an error threshold based on the previous position estimates. | 07-05-2012 |
| 20130080050 | SYSTEMS AND METHODS FOR COMBINING A PRIORI DATA WITH SENSOR DATA - Systems and method for improving the presentation of sensed data (e.g., radar) by including a priori data. The a priori data is recast as if it were the output of a sensor. This allows the inclusion of the a priori data into an evidence grid that is combined with data from multiple types of sensors. Before the sensor data is combined into the evidence grid, the sensor data is aligned with the a priori data using an optimization algorithm. The optimization algorithm provides an optimum probability of a match between the sensor data and the a priori data by adjusting position or attitude associated with the sensor device. This removes any navigational errors associated with the sensor device data. | 03-28-2013 |
| 20130090846 | ROUTE MODIFICATIONS - A computer system and media for delivering routing information are provided. The computer system includes a routing engine, a database, and routing network that are employed to respond to routing requests and user modifications of routing information received in response to the routing requests. The routing engine receives the routing requests and generates routing information that illustrates a route and metadata for directions that guides a user when navigating the route. A user that is dissatisfied with the routing information may use route modification tools to alter the route in a manner that is consistent with the user's understanding of alternate routes that may supplement the routing information provided by the routing engine. The computer system receives the user modifications, stores the user modifications, and updates the routing network to learn the alternate route provided in the user modifications. | 04-11-2013 |
| 20130124085 | NAVIGATION SYSTEM AND NAVIGATION METHOD - According to navigation systems and methods, when a detected current position has deviated from a guidance route, a navigation device transmits a reroute calculation condition to an information distribution center including the current position and the destination, Based on the reroute calculation condition, the information distribution center determines whether a distance from the current position to a closest adjacent link is equal to or shorter than a predetermined distance. When the distance from the current position to the closest adjacent link is longer than the predetermined distance, the information distribution center distributes to the navigation device reroute prohibition information including information regarding the adjacent link and a maximum waiting time. The maximum waiting time is a time that must elapse before the navigation device can again transmit the reroute calculation condition. | 05-16-2013 |
| 20130173151 | REAL TIME TRAVEL DIRECTOR - A method for navigating through a predefined space is described herein. The method includes receiving, by a remote unit, a signal indicative of a selection of at least one destination category, wherein the selected destination category is associated with a plurality of destination locations. A position of each of the plurality of destination locations is determined within the predefined space. A final destination location is determined within the predefined space, an origination location of the remote unit is determined, and a first route is determined from the origination location to the final destination. The first route including each destination location included in the selected destination category. | 07-04-2013 |
| 20130184989 | APPARATUS AND METHOD TO INDICATE INSTRUMENT SATURATION - An apparatus and method to maintain traditional information presentation in a manner that is consistent with existing training and safety methodology, but eliminates confusion generated when a display symbol is placed in a fully pegged position by positively indicating that the symbol is off-scale and not representing actual accurate information. | 07-18-2013 |
| 20130317740 | Flight Management System - A flight management system of an aircraft is provided allowing notably the calculation of a trajectory over the terrestrial globe. The calculation of a trajectory is carried out with respect to a true North, true North being a navigation term referring to the direction of the geographical North pole with respect to a given position. When the current or estimated position of the aircraft is level with the pole, it then becomes impossible to define true North, true North being defined in all the directions or in no direction, depending on the calculation facilities used. The flight management system makes it possible to use a single calculation procedure whatever the current position or the position to be reached of the aircraft on the terrestrial globe. | 11-28-2013 |
| 20140032103 | METHOD OF DISPLAYING A FLIGHT PLAN - A method of displaying a flight plan on a flight display of a flight deck of an aircraft, where the method includes displaying at least a portion of the flight plan on the display and determining an unsuitability of at least a portion of the flight plan based on at least one suitability criteria. | 01-30-2014 |
| 20140107919 | PREDICTIVE SCHEDULING OF NAVIGATION TASKS - Disclosed are systems, apparatus, devices, methods, computer program products, and other implementations, including a method of controlling navigation tasks on a mobile device that includes obtaining data representative of a route of travel for the mobile device, obtaining a list of navigation tasks associated with the route of travel for the mobile device, and performing one or more navigation tasks in accordance with the list of navigation tasks based, at least in part, on proximity of the mobile device to one or more points on the route of travel. Performing the one or more navigation tasks includes one or more of, for example, obtaining satellite positioning assistance data in response to a determination that the mobile device is transitioning from an indoor area to an outdoor area, and/or establishing a communication link with an access point. | 04-17-2014 |
| 20140200805 | DEVIATION DETECTION IN MOBILE TRANSIT SYSTEMS - In one embodiment, a mobile device or a network device is configured to identify when a transit vehicle deviates from a transit path. The mobile device is configured to perform a positioning technique to generate data indicative of the location of a mobile device. Based on the location of the mobile device, a path is identified. The path is associated with an estimated path width based on the classification of the path and/or the accuracy of the positioning technique. A target route is calculated using the estimated path width. As the transit vehicle travels, the target route is compared to the location of the mobile device. If the mobile device and or transit vehicle deviates from the target route, a message is generated. The message may indicate that the transit vehicle is being re-routed and/or recommends the computation of a new path. | 07-17-2014 |
| 20140288822 | CONTROLLING POSITION UNCERTAINTY IN A MOBILE DEVICE - Systems and methods for constraining growth in position uncertainty of a mobile device are based on determination that the mobile device is in a pedestrian mode. Determination of the pedestrian mode is based on detection of steps by a pedometer, speed of motion of the mobile device, turn rate determination by a gyroscope, charging condition of the mobile device, availability of satellite signals, etc. Step counts and/or turn rate information are used to ascertain the distance that a pedestrian user may have traversed from a last known position, based on which growth of position uncertainty is controlled. | 09-25-2014 |
