EEG Spectral Analysis

AcqKnowledge can be used to obtain the power spectrum of the EEG, with frequency representation in linear or logarithmic scaling. The power spectrum, which can be used to analyze a variety of physiological signals, indicates the power of frequency components in the source time domain waveform and is defined as the square of the linear spectrum […]

EMG and Movement Analysis

AcqKnowledge includes tools to set limits and thresholds to isolate specific events within data files from surface EMG (sEMG) and movement (e.g., accelerometry or goniometry) recordings to identify when a subject is actually moving versus experiencing a muscle tremor episode. After events are identified, users can perform cross-channel analysis on the rest of the data to […]

Heart Rate Variability (HRV) Analysis Software

AcqKnowledge® includes a series of automated Heart Rate Variability (HRV) analysis tools that conform to international cardiology standards. It is possible to perform the analysis over user defined selections of data, or automatically within user specified time periods, or between stimulus presentation event marks, or user entered event marks. The user can also create focus […]

Multi-Channel Sleep Recording

Record up to 16 channels of sleep data. Review data in 15- or 30-second epochs for quick visual assessments. Use the Journal to indicate points of interest in the sleep record. Copy critical measurements to the Journal with a single command.

Network Data Transfer – video demo

Run 3rd-party applications in parallel with AcqKnowledge AcqKnowledge with Network Data Transfer has the capability to send all of its channels over the network to other computers as well as the same computer. The data from AcqKnowledge—such as physiological recordings, digital markers, and calculation channels—can be used in real time by other applications.

Online ECG Analysis – Heart Rate and Inter-Beat-Interval

The AcqKnowledge Rate detector has automated tools for deriving heart rate (HR) and inter-beat-interval (IBI) on a cycle-by-cycle basis. The Rate detector operates in both real-time and off-line modes.  The algorithm contains a list of preset options for subject settings – resting human, exercising human, small animal, etc. The presets inlcude algorithm settings to optimize […]

Real-time EEG Filtering

Record single- or multi-channel montages with on-line calculation channels for Delta, Theta, Alpha, and Beta wave activity. On-line calculation channels allow the display of raw and filtered data in real time, and users can employ a variety of other transformations to filter the data off-line and further analyze the data. af_filt_eeg.gif

Remote Monitor – IP-Based Network Display

Simplified view of subject data on another computer or mobile device. Remote Monitoring provides a simple browser interface, from which acquisitions can be started, stopped and remote data viewed during and post-acquisition. Convenient “bedside monitor” displays trend data and current data to track the welfare of subjects and offers alarms to warn when signals fall […]

Respiratory Sinus Arrhythmia (RSA) Analysis

AcqKnowledge® includes a fully automated Respiratory Sinus Arrhythmia (RSA) analysis routine that measures the maximum and minimum changes in heart rate during respiration and reports the difference between the two values. The RSA routine requires two signals to perform the analysis: ECG Lead II and respiration. The software locates and marks the components of the […]

Seizure Detection

Automatically Identify, Mark, and Report Seizure Episodes in Small Animal EEG Data AcqKnowledge now includes an automated EEG seizure detection routine that employs a spike frequency technique to identify seizures. The software identifies and marks seizure spikes and counts the number of spikes that occur in a given interval. The routine can be used on […]
