        Quality Assurance inspector on large airplane assembly line

Application Description:

A Quality Aassurance (QA) inspector visually determines that a repair must be
made at a specific location on an airplane. The location must be recorded
with sufficient fidelity that a repair mechanic can subsequently locate the
problem easily and precisely. Ideally, the QA inspector would point a wand
at the problem location, press a button on the wand or portable belt pack,
and the x,y,z coordinates of the wand would be transmitted to a nearby
microcomputer. The computer, in turn, would map the x,y,z coordinates
to the location terminology recognized by the airplane industry (a very
non-trivial task). After transmitting the location to the computer, the
inspector would then transmit to the computer information that describes
the nature of the problem and the required corrective action.
