Absolutely amazing. The APAS performed the best over all other
As reported during the original Conference presentation
based on the test results, the APAS performed the best in determining the actual 9 cm by
detecting the distance as 9.015 cm.
Slide 13. Average Measured Distance between Top Plate Markers.
(Slide was photographed in the original presentation)
The results for the measurement of the distance between
the top two markers on the rotating plate is presented in Table 1. The known
distance between the two top plate markers was 9.0 cm.
Slide 13 illustrates the average measured distance
between top plate markers.

In all cases, the APAS system performance was superior to all other
companies. The APAS system scored first with 20 points. The second best performer was the
Vicon company. However, remember that the switching points errors were not
considered. Had the switching points been considered for Vicon, the error would have
As one can observe, The APAS system yielded 9.015 cm with the lowest error of .087 cm.
The total error amounted to the sum of the RMS and the maximum error and was the best of
all systems. The APAS scored 20 points for this test with Vicon second with 15 points.
In Slide 14 it is clearly demonstrated that the APAS
system had the lowest error. The unrealistic results obtained by Elite can be seen
and, for this reason, the author of the report decided not to include their results.
