Abstract: A method is provided for tracking a single presumed target by a plurality of scopes located remotely from one another and being moved by separate scope operators. Each of the scopes include a plurality of measurement devices configured to provide current target position data. Each of the scopes are in electronic communication with a network server. The current target position data has error values. Current target position data from scopes that located the presumed target are amalgamated, thereby providing current target position data having reduced error values compared to the error values of the current target position data identified by only a first scope that located the presumed target. Temporal factors are used in the amalgamation.

Abstract: A method including operating a vehicle in a medium. The vehicle is subject to advection due to movement of the medium. The method also includes measuring, using a navigation system, positions of a vehicle over time. The method also includes measuring, using a directional sensor, a course-through-medium over the time. The method also includes calculating, using the positions and the course-through-medium, a variation of a speed-over-ground of the vehicle over the time as a function of the course-through-medium over the time. The method also includes concurrently estimating, using the variation, 1) an average speed-through-medium for the vehicle over the time, and 2) an advection rate of the medium, and 3) an advection direction of the medium.

Abstract: A network of scopes, including one or more lead scopes and one or more follower scopes, is provided to allow the respective scopes to track the same presumed target. A lead scope locates a target and communicates target position data of the presumed target to the follower scope. The follower scope uses the target position data and its own position data to generate electronic control signals for use by follower scope to make position movements so as to re-position the follower scope from its current target position to move towards the target position defined by the target position data received from the lead scope. At least the second scope is mounted to, or integrated into, a vehicle, which uses the target position data to move to a new location so as to allow the second scope to better view the target.

Abstract: Examples of systems and methods for locating movable objects such as carts (e.g., shopping carts) are disclosed. Such systems and methods can use dead reckoning techniques to estimate the current position of the movable object. Various techniques for improving accuracy of position estimates are disclosed, including compensation for various error sources involving the use of magnetometer and accelerometer, and using vibration analysis to derive wheel rotation rates. Also disclosed are various techniques to utilize characteristics of the operating environment in conjunction with or in lieu of dead reckoning techniques, including characteristic of environment such as ground texture, availability of signals from radio frequency (RF) transmitters including precision fix sources. Such systems and methods can be applied in both indoor and outdoor settings and in retail or warehouse settings.

Abstract: An electronic device determines an estimate ({circumflex over (q)}) of angular position as a function of an accelerometric signal (acc) supplied by an accelerometric sensor and as a function of at least one between a gyroscopic signal (gyro) supplied by a gyroscopic sensor and a magnetic signal (mag) supplied by a magnetic-field sensor. A processing module implements a complementary filter, which is provided with a first processing block, a second processing block, and a combination block. The first processing block receives the acceleration signal (acc) and an input signal (mag′) indicative of the magnetic signal (mag) and generates a geomagnetic quaternion (qAccMag). The second processing block receives a signal indicative of the gyroscopic signal (gyro) and generates a gyroscopic quaternion (qGyro). The combination block determines the estimate ({circumflex over (q)}) of angular position by complementarily combining the geomagnetic quaternion (qAccMag) and the gyroscopic quaternion (qGyro) based on a combination factor (K) that has a dynamic value and an adaptive value and that varies as a function of the operating conditions.

Abstract: The invention provides a much improved process for locating underground utilities where a field technician is provided with a device that presents the location of the underground utility in context with the surroundings. The device uses a screen present an image of the underground utility in its proper perspective with respect to the surroundings using data gathered from a number of sources. The data used to create the image includes location data of both the underground utility and the position of the device along with perspective attributes such as traditional compass orientation, perspective relative to the horizon, and any perceivable movement of the device.
