Physiology Data Analyzer System (BIOMAS）
|
Features
|
●Capable to scale and analyze cardiogram, brain wave, electromyography, body temperature etc to 100 frames, and without time limit.（※)
●Capable to do high level analysis using operation functions such as Wavelet, FFT, MEM, AR, Chaos analysis, digital filter etc.
●Equipped with “Virtual sampling” which enabling changing each frame’s sample rate and also enabling analyzing high-resolution waves.
●Comment insertion function which enabling inserting comments to time positions that is very useful when writing a report.
●Capable of determine min/max value of all waves / certain wave at high speed.
●Substance definite form process functions: by combining operations in user settings, will enabling to realize heartbeat / fluctuation analysis.
※Depends on the hard disk’s capacity
