March 24, 2009 - Helium Polish version 4.49 is released.

1. New cuts Cushion, Radiant and Square Radiant are constructed by Helium Polish
2. Girdle sides and girdle internal angles are available for princesses, step cuts, radiants, square radiants and others
3. New Algorithm for Automatic control of holder height
4. Accuracy of defining the directions of minimum and maximum diameters is increased

1. New cuts Radiant, Square Radiant and Cushion are constructed by Helium Polish

New algorithms for constructing Cushion, Radiant and Square Radiant cuts are available.

To create new cuts Radiant and Square radiant select P-O-M-H-R from menu Cutting:

The new algorithm P-O-M-H-R allows to create several cuttings: Pear - Oval - Marquise - Heart - Radiant

2. Girdle sides and girdle internal angles are available for princesses, step cuts, radiants, square radiants and others

Girdle sides and girdle internal angles are available on the Girdle asymmetry picture in the reports for straight edge cuts: princesses, step cuts, radiants, square radiants and others.

3. New Algorithm for Automatic control of holder height

The Automatic control of holder height option allows to adjust a holder height position if device has not stable holder height because of device temperature enlargement. The program does the check-up automatically while the device is not scanning. If the system discovers small or critical offset of holder height the operator will see one of three warnings:

To continue work with scanner need to make cleaning and checking holder position:

• Remove diamond (if it is inside the scanner)
• Press button Camera to see holder surface
• Clean holder surface
• Close cover of scanner before checking
• Press button Clean & Check
• System make checking holder position

As a result of checking holder position the one of the follow warnings appears:

1. System could not calculate vertical holder position
2. System has found negligible vertical holder shift
3. System has found small vertical holder shift
4. System has found critical vertical holder shift

1) System could not calculate vertical holder position

This warning means that system could not calculate vertical holder position. Possible reasons are diamond is on holder, the dust is on holder. Try again:

• Remove diamond (if it exist in the scanner)
• Clean up holder surface
• Close cover of scanner before checking
• Press button Clean & Check to calculate vertical holder position one more time

If the system could not calculate vertical holder position in the second time the follow warning appears:

In this case the scanning process will be blocked. Please contact to support service for adjusting holder position.

Note. If try to continue working with scanner the follow warning appears:

2) System has found negligible vertical holder shift

System has found negligible vertical holder shift. Holder was moved on ... mm.
System will work with previous holder position. Press button OK

3) System has found small vertical holder shift

System has found small vertical holder shift. Holder was moved on ... mm.

We recommend press button Set to update vertical holder position. If you sure the holder is really clean.
Press button Continue to ignore this shift and continue scanning stones if you sure the shift provided by other reasons, dust on holder and so on, not because of device temperature enlargement. But this might increase errors in values of diamond parameters during scanning.

4) System has found critical vertical holder shift

System has found critical vertical holder shift. Holder was moved on ...mm.
Press button Set to update vertical holder position.

4. Accuracy of defining the directions of minimum and maximum diameters is increased

The accuracy of defining the directions of minimum and maximum diameters is increased from 0.5 degree to 0.01 degree. Because of this the values of minimum and maximum diameters are changed. Maximum difference in comparison with previous version of software is reached for cuts with long girdle facets like emerald cut. Also the difference is significant for square fancies like princess, radiant and etc.

The model construction is not changed.
