| 20100039656 | METHOD FOR DETERMINING AN INFLUENCING VARIABLE ACTING ON THE ECCENTRICITY IN A GONIOMETER - The invention relates to a method for determining at least one influencing variable acting on the eccentricity in a goniometer, using a detector arrangement consisting of four optical detector elements, and a rotational body comprising a plurality of pattern elements arranged around a pattern center, the rotational body being rotatably arranged about an axis. According to said method, at least some of the pattern elements are reproduced on the detector arrangement, the positions of the pattern elements reproduced on the detector arrangement are resolved, and the eccentricity of the pattern center in relation to a detector center of the detector arrangement is determined. A plurality of such eccentricity measurements for different rotational positions enables different influencing variables acting on the current eccentricity to be separated, especially by forming units. | 02-18-2010 |

| 20110112786 | CMM WITH IMPROVED SENSORS - A method of operating an articulated arm CMM is provided. One or more coordinates on an object can be measured with the articulated arm CMM. At least one of the encoders can then be at least partially powered-off. The encoder can then be powered on and one or more coordinates on the same object can be measured without recalibrating the encoder. | 05-12-2011 |
| 20110272566 | OPTOELECTRONIC POSITION MEASUREMENT DEVICE AND OPTOELECTRONIC POSITION MEASUREMENT METHOD - An optoelectronic position measurement device having a code carrier that carries at least one optically registered position code and that is illuminated with optical radiation from a radiation source. At least one portion of the optical radiation is registered by at least one registration element, by means of which a signal dependent on the position code can be created and a position of the code carrier relative to the registration element can thus be registered. the code carrier is movable relative to the registration element with a degree of freedom. the optical radiation couples into the code carrier and is guided at least partially in a beam path in the interior of the code carrier lying in the extension level of the code carrier. The decoupling of the optical radiation occurs in a decoupling zone such that the registration element is illuminated by a substantially homogenous intensity distribution. | 11-10-2011 |
| 20110315864 | OPTOELECTRONIC ANGLE SENSOR - The invention relates to an optoelectronic angle sensor for determining a rotational angle about an axis, comprising a code carrier ( | 12-29-2011 |
