Structural Measurement Systems (Spectral Dynamics)

Project Descriptions

Structural Measurement Systems has two products 1) providing STAR software to measure structural vibrations and 2) STARAcoustics to measure acoustical noise. The products come complete with fully animated graphics displays, charts, and color printouts.

The STAR software measures how objects such as airplanes, cars, disk drives, or any other structure subject to constant vibration reacts to those vibrations. A structure (e.g. disk drive) definitely should not have a harmonic at its normal operational speed (e.g. 7200 rpm) lest it would vibrate apart.

Similarly, STARAcoustics measures sound intensities, sources of sounds, and harmonics. It is used to mitigate noise and provide a safe environment to work in. STARAcoustics can also be used by sound studios to develop recording facilities free of unwanted noise.

STARAcoustics	Project Lead

WinMac / Mark Kwan worked on two releases of Acoustics software. This involved software ports from Win 2.x to 3.0 to 3.1 . For the ports, and to prepare for Win32, a software conversion from C to C++ / MFC was implemented. Components developed or revised were 3-D animation, line graphs and database access. Project lead aspects included training, scheduling, and estimations.

STAR	Developer

WinMac / Mark Kwan worked on two releases of STAR software. This involved software ports from Win 2.x to 3.0 to 3.1. A significant capability of the software is to gather measurements from Fast Fourier Transform (FFT) Analyzers via GPIB (IEEE-488) interface. Each analyzer has its own protocol and needed to be custom interfaced. I dramatically improved the robustness of this module, which previously had a propensity to fail. Other modules developed were graphing, and various UI dialogs.
