| 20110231057 | METHOD FOR GENERATING OFFSET PATHS FOR GROUND VEHICLES - A computer-implemented method for generating at least one segment of an offset path for a vehicle based on at least one segment of a base path is provided. The at least one segment of the base path is represented by a stored set of data points. The computer-implemented method includes comparing the at least one segment of the base path to a curvature constraint to determine if the at least one segment of the base path violates the curvature constraint. The curvature constraint is based on a characteristic of the vehicle and a desired offset distance from the at least one segment of the base path. The characteristic reflects the vehicle's ability to traverse at least one segment of a path. The method further includes modifying the at least one segment of the base path to satisfy the curvature constraint, if the at least one segment of the base path violates the curvature constraint. At least one segment of an offset path for the vehicle to follow is generated based upon the desired offset distance from the modified at least one segment of the base path. | 09-22-2011 |
| 20110075886 | GRAPHICS-AIDED REMOTE POSITION MEASUREMENT WITH HANDHELD GEODESIC DEVICE - A graphics-aided geodesic device is provided. The device may include a display, camera, distance meter, GNSS (Global Navigation Satellite System, including GPS, GLONASS, and Galileo) receiver and antenna, and horizon sensors. Data from the camera and horizon sensors may be displayed to assist the user in positioning the device over a point of interest. In one example, the distance meter may be used to determine the position of the point of interest. In another example, images of the point of interest taken from multiple locations may be used to determine the position of the point of interest. | 03-31-2011 |
| 20100265505 | LASER BEAM IMAGE CONTRAST ENHANCEMENT - An apparatus and method for providing image contrast enhancement is disclosed. A mobile object is equipped with a laser source, polarization filter, and imaging apparatus. The reflection of the laser source output passes through the filter and is received by the imaging apparatus. If the output of the laser source impinges a metallic marker plate located at a pre-determined location, the filter decreases the intensity level of image components not associated with the reflection of the laser source output. The imaging apparatus uses such filtered image components to determine the position and/or orientation of the mobile object. | 10-21-2010 |
| 20100211314 | PORTABLE MULTIBAND ANTENNA - A portable DGPS navigation apparatus is provided. The apparatus includes a receiver assembly and a DGPS antenna assembly. The receiver assembly includes a GNSS antenna, a GNSS receiver, and a DGPS modem. The DGPS antenna assembly includes a DGPS antenna; a top connector for coupling the DGPS antenna assembly to the receiver assembly such that the receiver assembly and DGPS antenna assembly are aligned with a geodetic pole, and a bottom connecter. | 08-19-2010 |
| 20090195475 | PORTABLE NAVIGATIONAL ANTENNA SYSTEM - A portable navigation apparatus is provided. The apparatus includes a multi-antenna assembly configured for including an expanded configuration and a collapsed configuration. The antenna assembly includes a master antenna, and at least two auxiliary antennas. The at least two auxiliary antennas are radially distributed about the master antenna. Furthermore, the master antenna and auxiliary antennas are substantially coplanar when the antenna assembly is in the expanded configuration. | 08-06-2009 |
| 20090189804 | SATELLITE DIFFERENTIAL POSITIONING RECEIVER USING MULTIPLE BASE-ROVER ANTENNAS - A rover processor determines position of a rover based upon the interaction between multiple antennas located at the rover and multiple antennas located at a base. The rover antennas may include a rover master antenna having a phase center located at the centroid of the antennas patterns of at least two auxiliary rover antennas. The rover processor may determine the position of the rover master antenna based upon the relative positions of at least two rover antennas (e.g., the rover master antenna and at least one rover auxiliary antenna, or at least two rover auxiliary antennas) with respect to at least two antennas of a base transceiver. | 07-30-2009 |
| 20080208454 | Path approximation for planar motion of a ground vehicle - The generation of a planar trajectory for use by a vehicle in guiding its position is described. The trajectory is generated by identifying points representing the trajectory, fairing the identified points to generate a set of faired points, and computing a set of polynomial segments from the faired points. The segments form a curve representing the trajectory, where the curve is C | 08-28-2008 |
