QUASAR presents at the IDGA UAV Summit West
San Diego, CA, USA. November 7, 2011QUASAR was invited to present its work on "Physiologically-Driven Adaptive Aiding for UAV Operator" at the UAV Summit West conference. QUASAR presented work done under funding from the Air Force, where we used our EEG headset and ECG chestbelt to monitor the cognitive workload of UAV operators in real-time during the performance of a multi-UAV control task. Supervisors could use mission scenario and cognitive workload information in deciding to re-allocate tasks between the operators accordingly. The results indicate that supervisors with information on the operators cognitive workload can make decisions that are more beneficial to team performance than those without this cognitive information.
DSI 10/20 Price Reduction
San Diego, CA, USA. September 29, 2011One year has passed since the commercial launch of our Dry Sensor Interface (DSI) 10/20 system at SfN 2010. We are proud to announce that during this year, we have achieved a 15% manufacturing cost reduction, which we are happy to pass on to you.
The technology is unchanged; QUASAR’s dry sensors still record high
quality EEG signals without skin preparation, gels or fluids. The DSI 10/20
is a wireless headset that positions up to 21 dry sensors at the 10/20 International
System locations. The system is designed for comfortable long-term ambulatory
operation in laboratory or office environments.
Clinical Trial Pilot conducted with DSI 10/20 at UTMC
Houston, TX, USA. September 25, 2011
Dr. Jeremy Slater, Associate Professor of Neurology at The University of
Texas Health Science Center at Houston, and Director, Texas Comprehensive Epilepsy
Program, and his team of researchers, epileptologists, and EEG technicians,
in collaboration with Advanced Neurometrics Inc (ANI)
recently conducted a clinical evaluation of QUASAR's DSI 10/20.
The purpose of the study was to investigate the suitability and advantages of QUASAR's Dry Sensor Interface for use in clinical settings. The specific aims evaluated in this study were: 1) Time to interpretable EEG, 2) Subjective data quality. For the first aim, EEG technicians recorded the time it took to place a headset on a patient's head, position the sensors through the hair, and get meaningful EEG signals. For the second aim, data recorded from patients with the DSI 10/20 and a clinical wet EEG system were blinded and presented to epileptologists for evaluation of data quality and ability to detect signals of interest.
Preliminary results are encouraging, suggesting that the headset could be put on in an average of 198.9 seconds compared to 872.6 seconds for a comparable wet montage (t-test, statistical significance of p = 0.000040827), and that data quality is comparable between dry sensors and wet electrodes. We look forward to the completion of their study and the publication of their final results.
QUASAR awarded project from DARPA
San Diego, CA, USA. September 23, 2011QUASAR has recently been awarded a research contract from DARPA titled “Practical EEG Headset for Brain-Machine Interfaces”. The goal of this project is to further advance QUASAR’s DSI ambulatory EEG technology to an even greater level of practicality and robustness, which would enable cognitive monitoring solutions in rigorous applied and fielded military environments.
QUASAR presents at IEEE EMBC 2011
Boston, CA, USA. August 30 - September 2, 2011QUASAR was invited to participate in a Cognitive State Assessment Competition, at the IEEE EMBC conference. QUASAR presented results of QStates Cognitive Gauge Performance on the competition data set. See the paper describing the work and results.
QUASAR introduces the Dry Sensor Innovation Challenge
San Diego, CA, USA. August 29, 2011QUASAR launches the Dry Sensor Innovation Challenge to promote novel applications of Dry EEG Sensors. This challenge offers researchers whose work would substantially benefit from the use of dry EEG sensors the opportunity to use QUASAR’s revolutionary Dry Sensor Interface (DSI) technology to augment their projects. Exploring the advantages of dry-sensor technologies in clinical, academic, or commercial applications is the principal goal of this competition.
Independent validation of QUASAR’s dry EEG sensors confirms performance comparable to wet electrodes

Glenn F. WilsonA group led by Air Force Research Laboratory personnel conducted a study in which simultaneous EEG measurements were taken on subjects wearing both a QUASAR EEG headset and conventional wet electrodes. According to a paper published in the Proceedings of the 53rd Annual Meeting of the Human Factors and Ergonomics Society, results “demonstrate that the QUASAR system is capable of collecting EEG data that is comparable to that collected via conventional wet electrodes.”(See the paper)*

QUASAR launches DSI 10/20
DSI
10/20, Launched 11/13/2010This wireless ambulatory headset positions 21 sensors at 10/20 locations for comfortable long-term wear. The headset integrates with a Physiological Status Monitor (PSM) belt that records ECG, skin temperature and 3-D acceleration. The system includes powerful real-time trainable cognitive state gauges.

QUASAR
receives SBIR grants from NIH and NSF
San Diego, CA, USA. September 23, 2011
QUASAR
has received grants from the National Institute of Health and
the National Science Foundation for scientific investigation of
innovative ideas related to biosensing. Under the NIH funding,
QUASAR will pursue development of a simple, pad-like device to
acquire ECG that can be integrated into a chair for a comfortable,
long-term ECG acquisition interface. Working under NSF funding,
QUASAR will develop an idea for a totally new biosensing technology
that has shown the potential for never-before-seen levels of noise
performance, offering the opportunity to greatly enhance applications
such as EEG-based brain mapping that require precision signal
measurements.
