If you don't see an Advanced Feature that interests you, please contact BIOPAC so we can identify the best solution for your particular need.

Actigraphy

Actigraphy noninvasively measures cycles of activity and sleep (rest) over days or even weeks, typically to assess sleep disorders and other sleep-related criteria. Use the Actigraphy Analysis licensed feature in AcqKnowledge® to record long-term accelerometer data of mobile subjects and then analyze sleep and activity patterns; correlate activity levels with GPS positioning for more detailed […]

Auditory (AER) and Visual Evoked Response (VER) Testing

Combine the auditory output options of the Stimulator with the signal averaging functions of the MP System to perform online Auditory Evoked Response (AER) studies. Display the results and measure the amplitude and time of Fast (2-12 msec), Middle (12-50 msec), Slow (50-300 msec), and Late responses (250-600 msec). Use the stroboscope and the averaging […]

Auditory Brainstem Response (ABR)

MP Devices can be used for a wide variety of Brainstem Evoked Potential (BEP), Brainstem Evoked Response (BER), Brainstem Auditory Evoked Potential (BAEP), Brainstem Auditory Evoked Response (BAER), Brainstem Evoked Response Audiometry, and Brainstem Evoked Response (BSER) tests. The MP device is capable of delivering auditory stimulation and recording and averaging the response data. The […]

Auto-correlation & Cross-correlation

These software tools provide building blocks for template matching, waveform analysis, algorithm development, vector operations, and more. To obtain the auto-correlation of a signal, correlate a channel with itself. To correlate one channel of EEG data with another, use the off-line correlation function in AcqKnowledge. To obtain the power spectral density, perform the FFT on […]

Automated Data Analysis

There are a variety of tools for measuring response times and response amplitudes. Perform measurements manually by selecting an area of data, or automatically over specified time periods or around the time of a trigger (pre- and post-trigger values). Measurement results can be automatically entered into a journal file for further analysis or displayed as […]

Automated ECG Analysis

AcqKnowledge provides a fully-automated ECG analysis system. The software automatically identifies and labels the points of the ECG complex. It also calculates the amplitudes and timing intervals and pastes the results either into the Journal file or Excel® (see table below).

Automated EEG Analysis

AcqKnowledge includes a number of fully automated EEG analysis functions. Compute Approximate Entropy Approximate entropy is a statistical measure that attempts to quantify the predictability of a data sequence. A perfectly predictable data series (such as a pure sine wave) has an approximate entropy of zero. Several studies are beginning to examine approximate entropy of […]

Automated EMG Analysis

AcqKnowledge includes a number of powerful automated EMG analysis features, including Derive Average Rectified EMG Derive Integrated EMG Root Means Square EMG EMG Frequency & Power Analysis   Locate Muscle Activation Derive Average Rectified EMG   Derive Average rectified EMG (ARV) is defined as a time-windowed mean of the absolute value of the signal. ARV […]

Automated Noninvasive Blood Pressure – Human

The NIBP100D Noninvasive Blood Pressure System automatically records noninvasive blood pressure. The NIBP100D system attaches to the fingers of a human subject to output a continuous noninvasive arterial pressure (CNAP) signal. The system will work for short and long-term studies that demand several hours of monitoring. Combine the blood pressure signal with a variety of […]

Automatically Control Other Equipment

The MP System will interface with a wide variety of devices such as pumps, valves, stimulators and switches. The MP System has 16 digital I/O lines that can be manually or automatically controlled with the AcqKnowledge® software. By using the on-line Calculation and Control channel functions it’s possible to automatically trigger devices to turn on […]

Optimize Event-Related EDA

Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
