KB0008: LabVIEW: Memory is Full Error
If the analysis application gives a “LabVIEW: Memory is full error” when a file is selected for analysis then it is most likely due to corruption of the application configuration files. The following steps will re-initialize the configuration file:
KB0009: Change DEP Settings
When an application appears in the Task Bar and immediately disappears without ever opening, it is likely that Data Execution Prevention (DEP) has been enabled and the MindWare application has not been made an exception. The following steps show how to change DEP settings on Windows 7:
KB0010: Creating a Summary Event Channel in AcqKnowledge
Select analysis version to modify content below: This solution describes how to combine several individual digital event channels into a summary event channel in AcqKnowledge for use in the MindWare analysis applications.
HRV vs. IMP : Why R We Editing Twice?
HRV vs. IMP : Why R We Editing Twice? Collecting and editing the ECG signal is crucial to performing heart rate variability (HRV) and impedance cardiography (IMP) analysis. In both of these cases it is necessary to identify a landmark on the ECG waveform to identify a beat. Using a […]
