A system is provided for communicating between a 3D metrology device and a portable computing device via near field communications. In one embodiment, the metrology device is an articulated coordinate measurement machine (AACMM), a laser tracker, a laser scanner or a triangulation scanner, and the portable communications device is a cellular phone or a tablet. The portable device may use the NFC to establish to change or establish settings and parameters or to replace at least a portion of the operating system used to control the metrology device.

A measuring assembly for measuring the contour of a workpiece has a measuring probe that is pivotably supported and deflectable about a first axis (measuring axis) in order to contact a surface of the workpiece, and has a second axis that is associated with the workpiece. The first axis and the second axis are parallel or approximately parallel to one another for radially contacting a surface of the workpiece. A device for rotating the measuring probe and the workpiece relative to one another is provided, such that the measuring probe contacts the surface of the workpiece during the rotation, and a device for plotting the angular deflection of the measuring probe as a function of the particular rotational position of the workpiece relative to the measuring probe is provided.

Methods to use a tool for dimensional verification of a vehicle frame suspension system bracket pocket having first and second cam slots, the tool including a first sub-assembly configured for insertion through and registration of the first cam slot; a second sub-assembly configured for insertion through and registration of the second cam slot; and an intermediate sub-assembly disposed between and attachable to the first and second sub-assemblies via a shaft, the intermediate sub-assembly including an extension rod receiving feature defining at least one extension rod receiving aperture; wherein the sub-assemblies lock against the bracket walls to define a horizontal center axis and are adjustable to determine and register a center point along an intersecting vertical center axis between the first and second cam slots that is alignable with the at least one extension rod receiving aperture.

A method and apparatus for measuring a subject's ability to perform a varying range of barrier reaches is provided. The apparatus includes a barrier having a substantially horizontal upper surface at a height above a base point. A sensing and recording device is positioned adjacent to the barrier for sensing and recording a plurality of data points. A marking device for grasping by the subject engages the sensing and recording device for creating the plurality of data points as the subject bends forward against the barrier. The data points are recorded and converted into an interpolated arc reflecting the subject's reach at the barrier height.

A linear gage includes a spindle, a guide cylinder surrounding a portion of the spindle and configured to guide the spindle to move forward and rearward in an axis line direction, and a guide slit portion having a guide slit extending parallel to the axis line of the guide cylinder, with a gap provided between the guide slit and an outer surface of the guide cylinder. An attitude adjustment pin extends into the guide slit and is fixed to a side surface of the spindle. The attitude adjustment pin is an eccentric pin.

A method and system for measuring a turbine shape is provided in which an appropriate measurement accuracy can be achieved that is sufficient to prevent a failure to recognize features of shape of a measurement object, with extension of a measurement time suppressed. In a turbine including casings, recesses and protrusions on flange surfaces of the casings are measured at measurement intervals M set on the basis of the entire length L of flange portions in an axial direction, the number of bolts N joining the flange portions, and intervals between the bolts in the axial direction of the flange portions.

The present disclosure relates to a method in materials testing to automatically locate the center of a feature on or in an object using the off-axis force feedback of a loadcell. In this disclosure, either a simplified model of the product or device being tested, or the product itself, is placed under the loadcell probe with the feature of interest roughly aligned under the probe tip. The probe is driven down into the feature. The product is automatically positioned relative to the probe in the x-direction until the side of the probe contacts the side of the feature. Contact is determined by monitoring the force feedback from the loadcell. When the vertical force from the side-load surpasses a pre-determined setpoint, contact is assumed and the value of the x-position of the product with respect to the probe is recorded. The product is then repositioned in the opposite direction in the x-axis to record the touch load on the other side. The center is then calculated as the average of the x values. The process is repeated along the y-axis. This data is then used to calculate the center of the feature and the product can be positioned at this location so that the probe is centered over the center thereof.
