Abstract: Systems and methods for transmitting measurement data wirelessly are described herein. A coordinate measurement device comprises an articulated arm comprising a plurality of articulated arm members, a coordinate acquisition member at a distal end, and a base at a proximal end. The device further comprises an add-on device assembly coupled to the coordinate acquisition member. The device further comprises a feature pack coupled to the base of the articulated arm. The feature pack may receive the coordinate data and the add-on device data packet, inserts bits of the coordinate data into a packet that can be transmitted over a network, and wirelessly transmits the packetized coordinate data and the add-on device data packet to a base station.

Abstract: Apparatus and methods are provided for measuring thread leads or pitches using a metrology probe. The probe may be, for example, either a contact probe or a laser probe. The probe is mounted on the end of an articulating arm that has sensors to provide precise three-dimensional coordinates of the probe's location and orientation. The probe determines surface coordinates of the threaded object repetitively in different locations according to a program provided by a computer connected to the arm. When enough data have been gathered, the computer calculates and outputs a surface profile of the threaded object, including a lead or pitch measurement.
