| 20120017454 | COORDINATE MEASURING MACHINE WITH ROTATABLE GRIP - A portable coordinate measuring machine (PCMM) can have one or more rotatable grip assemblies to provide a locations for an operator to grasp the PCMM. A rotatable grip assembly can include a rotatable sleeve, a grip portion disposed over the sleeve, and one or more retaining rings to prevent the rotatable grip from axially sliding along one or more members of an articulated arm PCMM. A PCMM can include two rotatable grips to allow an operator to grasp the PCMM with both hands for positioning and repositioning operations. One rotatable grip can be positioned on an arm member most distant the PCMM base, and another rotatable grip can be positioned on a housing at least partially encasing an articulating joint assembly coupled to the arm member most distant the PCMM base. Other numbers of and locations of rotatable grip assemblies can be used in PCMMs. | 01-26-2012 |
| 20110213247 | ARTICULATED ARM WITH IMAGING DEVICE - An articulated arm CMM comprises an articulated arm comprising a plurality of transfer members, a plurality of articulation members connecting at least two transfer members to each other, a coordinate acquisition member at a distal end, and a base at a proximal end. A plurality of encoders are associated with the plurality of articulation members so as to measure an orientation of the CMM. An ultrasonic imaging device is mounted on the CMM. | 09-01-2011 |
| 20110192043 | ARTICULATING MEASURING ARM WITH LASER SCANNER - A coordinate measurement device comprises an articulated arm having a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment defines at least one axis of rotation. A laser scanner assembly is coupled to the second end of the arm and is rotatable about a last axis of rotation of the articulated arm. The laser scanner assembly comprises a laser and an image sensor. The laser is positioned on an opposite side of the last axis of rotation from the image sensor. | 08-11-2011 |
| 20110119025 | MANIPULABLE AID FOR DIMENSIONAL METROLOGY - A manipulable aid which is separate and distinct from the probe of a CMM permits a CMM operator to more directly interact with a CMM measurement volume to align a workpiece, configure a measurement path, and/or program a dimensional metrology application. | 05-19-2011 |
| 20110000277 | METHOD AND APPARATUS FOR PROBE TIP DIAMETER CALIBRATION - A method for determining probe tip diameters with improved accuracy and reliability that includes performing a routine for determining probe tip diameter multiple times with the arm of the coordinate measurement machine in different machine positions. Diameter values associated with each of the calibration routines may be combined in a manner that provides more accurate diameter measurements. | 01-06-2011 |
| 20100281706 | COORDINATE MEASURING MACHINE WITH ROTATABLE GRIP - A portable coordinate measuring machine (PCMM) can have one or more rotatable grip assemblies to provide a locations for an operator to grasp the PCMM. A rotatable grip assembly can include a rotatable sleeve, a grip portion disposed over the sleeve, and one or more retaining rings to prevent the rotatable grip from axially sliding along one or more members of an articulated arm PCMM. A PCMM can include two rotatable grips to allow an operator to grasp the PCMM with both hands for positioning and repositioning operations. One rotatable grip can be positioned on an arm member most distant the PCMM base, and another rotatable grip can be positioned on a housing at least partially encasing an articulating joint assembly coupled to the arm member most distant the PCMM base. Other numbers of and locations of rotatable grip assemblies can be used in PCMMs. | 11-11-2010 |
| 20100272348 | TRANSPROJECTION OF GEOMETRY DATA - Systems and methods for transprojection of geometry data acquired by a coordinate measuring machine (CMM). The CMM acquires geometry data corresponding to 3D coordinate measurements collected by a measuring probe that are transformed into scaled 2D data that is transprojected upon various digital object image views captured by a camera. The transprojection process can utilize stored image and coordinate information or perform live transprojection viewing capabilities in both still image and video modes. | 10-28-2010 |
| 20090326849 | HYSTERESIS COMPENSATION IN A COORDINATE MEASUREMENT MACHINE - A coordinate measuring machine compensates for hysteresis error caused by friction at the non-driven end of the bridge. The bridge may have a single drive and/or a single scale. The methods, systems, and apparatuses compensate for errors in the x-direction and/or errors in the y-direction caused by rotation of the bridge. Some embodiments compensate for hysteresis errors in the x-direction caused by a vertically-movable ram. | 12-31-2009 |
| 20090150108 | Hysteresis compensation in a coordinate measurement machine - A single-scale, single-drive coordinate measuring machine that compensates for hysteresis error caused by friction at the non-driven end of the bridge. The coordinate measuring machine is calibrated to estimate hysteresis effects at one or more distances from the scale. Measurements of workpieces are adjusted based on the calibration data and the distances of the carriage from the scale at the point of the measurements. The scale and the drive system may be positioned on opposite guideways. | 06-11-2009 |
