The ATFX API C# DLL files can be used in three supported coding languages: Python, Matlab and LabVIEW. For the C# DLL files to work in Python, a specific package that allows Python to integrate with .NET Common Language Runtime needs to be installed. There are several packages that do this, such as IronPython and Python.NET. For this example, Python.NET will be used.

Written in collaboration between PCB Piezotronics, Inc., Crystal Instruments, and Team Icewave
Icewave has an overall record of seven wins and six losses. Marc DeVidts, Icewave creator and team lead, believes some of the losses may have been due to the blade not impacting opponents effectively. Because of the power behind Icewave, some of these losses can be attributed to self-inflicted damage from its own rotating horizontal blade. The modal testing will be used to help increase striking effectiveness.
