1. A coordinate measurement device comprising:
- an articulated arm having a first end, a second end, and a plurality of jointed arm segments therebetween, each arm segment defining at least one axis of rotation, a last axis of rotation being defined by bearings near a distal end of the arm; and
a laser scanner assembly coupled to the distal end of the arm wherein the arm continuously generates trigger signals which are received by the laser scanner and indicate a time at which the arm'"'"'s position is measured.

Abstract
A coordinate measurement device comprises an articulated arm and a laser scanner assembly. The articulated arm can have a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment can define at least one axis of rotation, and a last axis of rotation can be defined by bearings near a distal end of the arm. The laser scanner assembly can couple to the distal end of the arm. The arm can continuously generate trigger signals that are received by the laser scanner and indicate a time at which the arm'"'"'s position is measured.

5. A method of operating a coordinate measurement device comprising:
-
continuously measuring the position of an articulated arm; generating a plurality of trigger signals upon each measurement of the position of the articulated arm; transmitting the trigger signals to a scanner at an end of the articulated arm; acquiring a scanner measurement from the scanner; and associating the scanner measurement with a plurality of trigger signals. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
