B-Alert X10 EEG System with AcqKnowledge and Cognitive State
Part #: B-ALERT110CS-WA

Simple, portable, accurate, wireless

This complete system provides acquisition and analysis of high fidelity wireless EEG plus ECG with the B-Alert X10 headset and sensor strips (1 small, 1 medium), plus AcqKnowledge software with powerful analysis tools, including automated scoring and reporting options, and B-Alert Cognitive State analysis software. The B-Alert X10 mobile-wireless EEG system delivers real-time measurements for a variety of research and engineering applications, including closed-loop performance monitoring and simulation training; HCI design assessment; situational awareness and team dynamics monitoring; tools for productivity and training enhancement; and fatigue management.

The B-Alert X10 Wireless EEG system is an ideal platform for adding neuroscience to any study in real-world or simulated environments. The sensor strips apply all sensors simultaneously for fast set-ups with coverage of the brain’s executive functions (prefrontal cortex), motor control (motor-strip), and visual system activity (parietal region). Combined with the independently validated Cognitive State Metrics and Cognitive Workload Metrics that generalize across environments, first-time and experienced EEG researchers alike are provided turn-key analysis tools to enhance the likelihood of meaningful findings in their work.

Wireless EEG B-Alert X10 System
      Plus Classify Cognitive States

This system includes the B-Alert Cognitive State software with proprietary metrics for real-time monitoring of subject fatigue, stress, confusion, engagement and workload (classify data from B-Alert Wireless EEG systems). The GUI intuitively represents both the raw and processed data for easy understanding by even the untrained user. Each X10 requires its own computer, and a max of six (6) headsets can be used in the same room without cross-talk issues, provided that there’s one Bluetooth receiver for each headset.

To facilitate both real-time and offline analysis, the B-Alert gauges are fully customizable to fit the requirements of the user. In the standard format (shown below), the easy-to-read dashboard gauges (top left) and time series (bottom) windows present B-Alert’s highly validated second by second metrics: Engagement, Workload and Drowsiness (along with Heart Rate). Heat maps (top right) display EEG power spectral densities (PSD) in both spatial and temporal maps for the traditional Hz bands (Beta, Alpha, Theta, Sigma).

B-Alert gauges

B-Alert Wireless EEG bio-metrics are normalized to an individual subject using 5-minutes of baseline data from three distinct tasks with the sleep onset class predicted from the baseline PSD values. A probability-of-fit is then generated for each of the four classes for each epoch with the sum of the probabilities across the four classes equaling 1.0 (e.g., 0.45 high engagement, 0.30 low engagement, 0.20 distraction and 0.05 sleep onset). Cognitive State for a given second represents the class with the greatest probability. B-Alert cognitive state metrics are derived for each one-second epoch using 1 Hz power spectra densities (PSD) bins from differential sites FzPO and CzPO in a four-class quadratic discriminant function analysis (DFA) that is fitted to the individual’s unique EEG patterns. The table below identifies and briefly describes each baseline task, and associates the task with the B-Alert classification.

B-Alert Systems include AcqKnowledge Acquisition & Analysis Software

AcqKnowledge is an intuitive, interactive program that lets you instantly view, measure, transform, and analyze data. Perform complex data acquisition, stimulation, triggering, and automated analysis routines using simple pull-down menus and dialogs—no need to learn a programming language or new protocol. Online analysis settings, filters, and transformations provide real-time feedback, or you can choose from a wide variety of off-line analysis tools. Multiple display options are available during and after acquisition—just click on an icon to flip between Chart, Scope, X/Y, Overlapped segments, Histogram, or FFT. The software also includes quality presentation capabilities.
