| 20100134790 | OPTOELECTRONIC LONGITUDINAL MEASUREMENT METHOD AND OPTOELECTRONIC LONGITUDINAL MEASUREMENT DEVICE - The invention relates to an optoelectronic measurement method for determining a position, particularly an angle or a length, of a code carrier ( | 06-03-2010 |
| 20100149525 | Multi-dimensional measuring system with measuring instrument having 360.degree. angular working range - A multi-dimensional measuring system is disclosed wherein a laser-based tracking unit communicates with an optical target on a measurement instrument to obtain position and orientation information about the instrument. The optical target incorporates a plurality of encoders configured to provide a full 360° working range in pitch, yaw and roll. Full working range in pitch and yaw is achieved through the use of a pitch/yaw angular encoder. Full 360° working range in roll is achieved with a combination of a level sensor and a 360° angular encoder, which are fixed to a pendulum so that the level sensor is always aligned to gravity. Use of a slip-ring mechanism ensures the unlimited full working range in roll. The measurement instrument includes a scanner integrated with a probe receptacle adapted to accept a probe assembly to provide the instrument with both a scanning measurement and a probe measurement capabilities. Incorporation of an additional probe receptacle provides increased measurement capability and flexibility. The optical target with its full 360° angular working range in pitch, yaw and roll can be utilized independently of the measurement instrument. In combination with a laser tracker, the optical target can be attached to any object or surface to be measured, or alternatively, it can be attached to a movable device and the position of that device monitored. | 06-17-2010 |

| 20110176129 | System and Method For Providing A Polarized RF Reference System with Scanning Polarized RF Reference Sources and Their Self-Alignment for Munitions - Arbitrarily deploying scanning polarized RF reference sources and using them to establish a full position and angular orientation reference coordinate system or a full angular orientation reference coordinate system that objects property equipped with polarized RF sensors could use to determine their angular position and/or orientation relative to the reference coordinate system. | 07-21-2011 |
| 20110317154 | SYSTEMS AND METHODS FOR DETERMINING COORDINATE LOCATIONS OF SENSOR NODES OF A SENSOR NETWORK - Various embodiments of the present invention are directed to systems and methods for determining coordinate locations of sensor nodes of a sensor network. In one aspect, a method determines three-dimensional coordinates of a reference location in a terrain over which the sensor network is deployed. Beginning with the reference location, the method tracks the movement of an optical sensor as the optical sensor moves to each sensor node in series and determines a three-dimensional coordinate of each sensor node relative to the reference location based on data collected by the optical sensor. The method also programs the three-dimensional coordinate into each sensor node. | 12-29-2011 |
| 20130057852 | OPTICAL SYSTEM FOR MEASURING ORIENTATION WITH CUBIC WEDGE AND MASK - The field of the invention is that of optical systems for detecting the posture of a mobile object in space. The system comprises an electro-optical fixed device of known orientation comprising a first point emission source, a telecentric emission/reception optic and a photosensitive matrix sensor. An assembly comprising an optical cubic wedge is disposed on the mobile object. The input face of the cubic wedge comprises a mask in the shape of a parallelogram, each side of the parallelogram comprising a geometric marking making it possible to identify it, the image of the mask projected on the photosensitive matrix sensor, by reflection on the faces of the cubic wedge, being the intersection of the projection of the mask and of the projection of its image inverted with respect to the centre of the cubic wedge. Analysis of this image makes it possible to determine the orientation of the cubic wedge. | 03-07-2013 |
| 20130250285 | DEVICE AND METHOD FOR MEASURING SIX DEGREES OF FREEDOM - A laser tracker system for measuring six degrees of freedom may include a main optics assembly structured to emit a first laser beam, a pattern projector assembly structured to emit a second laser beam shaped into a two-dimensional pattern, and a target. The target may include a retroreflector and a position sensor assembly. A center of symmetry of the retroreflector may be provided on a different plane than a plane of the position sensor assembly. A method of measuring orientation of a target may include illuminating the target with a laser beam comprising a two-dimensional pattern, recording a position of the two-dimensional pattern on a position sensor assembly to create a measured signature value of the two-dimensional pattern, and calculating an orientation of the target based on the measured signature value. | 09-26-2013 |
