Abstract: An alignment apparatus (the tool) of the present invention includes a pair of bracket devices for rigidly holding shafts. As the shafts are secured to the bracket devices with chains, sensors of one of the bracket devices are exposed to an extension beam of the other bracket device thereby defining gaps or distances between the extension beam and the sensors. If offset is determined between the distances because one shaft is misaligned relative the other shaft, the sensors send signal to a mobile device, thereby informing a user about misalignment between the shafts.

The method includes the analog probe and/or object following a course of motion which causes the analog probe's surface sensing region to traverse across the feature to be found a plurality of times while approaching the feature over successive traverses so as to ultimately arrive in a position sensing relationship with the feature so as to collect scanned measurement data about the feature along at least part of a traverse.

Abstract: The present invention relates to a sensing system and a sensing method using the same. The sensing system includes at least one tested unit and an optical fiber measuring unit. The tested unit includes a container, a strain arm and a float. The container can be filled with a fluid, and the strain arm is connected with the float and combined with a measuring portion of the optical fiber measuring unit. When the container is disposed on a body of interest, the surface inclination or settlement of the body of interest would cause changes of buoyant force on the floating element and induce bending deformation of the strain arm. Accordingly, the surface deformation of the body of interest can be determined by detecting the bending deformation of the strain arm using the measuring portion combined with the strain arm.

Abstract: A fixture enables a stylus extension to be angularly aligned relative to an adapter plate that mounts onto a CMM probe head. Alignment may be carried out on a flat surface remotely from the CMM. The adapter plate is mounted to the fixture, which includes an access hole providing access to adjustment screws at the rear of the adapter plate. One or more lateral extensions are connected to the stylus extension to define a calibration axis perpendicular to a probe axis of the stylus extension and perpendicular to a central axis of the adapter plate about which angular alignment is desired. Angular adjustments of the stylus extension are made while the adapter plate is mounted to the fixture, and a degree to which the calibration axis is parallel to a plane of the flat surface is detected, for example using a dial indicator engaging points on the lateral extension(s).
