A first position measurement device (FPMD) is configured to control and operate both standalone and combined device operating modes. During the combined device operating mode, the FPMD inputs second-device measurement sample outputs provided by a second position measurement device (SPMD) via an inter-device communication connection. The FPMD and the SPMD are held in a fixed relationship in a workpiece measurement arrangement (e.g., with transverse measuring axes). Concurrent measurement data sets are determined as including at least a first-device measurement sample output from the FPMD and a second-device measurement sample output from the SPMD corresponding to concurrent first-device and second-device sample periods. Each concurrent measurement data set is associated with a corresponding measurement sample region on the workpiece. A combined measurement data output (e.g., as output and/or displayed by the FPMD) is provided for the current measurement sample region on the workpiece based on the corresponding concurrent measurement data set.

An apparatus reads a value measured with an analog measuring tool. The apparatus includes an imaging unit for obtaining a captured image of the analog measuring tool that is indicating a measured value, a retaining unit for retaining a 3D model of the analog measuring tool, a matching unit for specifying a 3D model matching the captured image, a guidance unit for outputting guidance information for correcting orientation of the analog measuring tool based on the matched 3D model, a reading unit for reading the measured value from the captured image to generate a measurement result, and an output unit for outputting the measurement result.

Disclosed is an electronic scale ruler, having a scale ruler main body, a main control board, an input, a display screen, a light source, a vernier base, and a distance conversion assembly. The scale ruler main body has an outer edge side. The light source is mounted on the outer edge side of the scale ruler main body, having a plurality of light beads and being capable of displaying scale. The vernier base is removably mounted on the outer edge side of the scale ruler main body, being capable of moving along a length direction of the outer edge side of the scale ruler main body. The distance conversion assembly is configured to calculate a movement of the vernier base from an origin on the outer edge side of the scale ruler main body.

A measuring instrument includes a measuring unit, an electric component unit and a pin jack. The electric component unit includes a signal processing part. The signal processing part is configured to calculate a measurement data based on a detection signal obtained by the measuring unit. The pin jack is provided in the electric component unit.

A tool is provided for characterizing a blade geometry. The tool includes a first component attachable to a blade root of a blade and a second component attachable to leading and trailing edges of the blade at a blade tip and at multiple stations defined along a span-wise dimension of the blade. The second component is configured for characterization of a chord length of the blade at the blade tip and at the multiple stations. The first and second components are respectively configured for cooperative optical characterization of a sweep and a twist angle of the blade at the blade tip and at the multiple stations.

A size gauge for a nut having flat edges, the size gauge comprises a first surface against which a first flat of the nut is placed, and a second surface against which a second flat of the nut which is adjacent the first flat is placed. The second surface is at an angle of about 120 degrees to the first surface. Distance markings are provided on the side gauge at or near the first surface, the distance markings indicating an across flat measurement based on the length of the flat.

A measuring instrument that includes a main body and a slide arm. The main body has a first plate with a first set of measuring identifiers, a second plate with a second set of measuring identifiers, a channel between the first plate and the second plate, and a measuring arm. The slide arm has a measuring arm and a slide rail. The slide rail is positioned within the channel and movable relative to the main body. The slide rail also has a plurality of measuring markers that can align with at least one of the measuring identifiers.

A method and apparatus for performing an operation on a workpiece using a multi-axis compliant end-effector for attachment to a robotic device. The end-effector is positioned at a nominal location of a workpiece feature on which the operation is to be performed. The end-effector is passively aligned with the workpiece feature by contacting the end-effector with the workpiece feature. The operation is performed on the workpiece feature in response to aligning the end effector with the workpiece feature.
