    QUASAR awarded Air Force contract to develop wearable sensor suite towards a Quantified Warrior
    San Diego, CA, USA. September 13 , 2017
    QUASAR is working with the Florida Institute for Human and Machine Cognition (IHMC) on a project for the Air Force to develop a suite of wearable, nonintrusive technologies for measuring such varied physiological signals as EEG, ECG, fNIR, electrodermal response, and respiration bundled with sophisticated data processing to quantify and thus help improve operator performance. Whereas the capability to measure these signals is already available, no current tool can combine them into a unified set of outputs corresponding to the operator's physical, cognitive, and psychological state and correlating these to a likelihood of error. The Quantified Warrior system will meet this DoD need.

    QUASAR awarded Phase II SBIR NIH grant to develop a dry electrode based Neonatal EEG MOnitor (“NEMO”)
    San Diego, CA, USA. March 15 , 2016
    QUASAR, in collaboration with Children’s National Medical Center and POLO Custom Products, has been awarded a Phase II SBIR grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Conventional EEG procedures can result in damage to tender neonatal skin, with infection risk a concern, and skilled technicians are required to apply the electrodes, which means recordings may have to be delayed until necessary personnel are available to apply the system. Treatment delays increase the negative outcomes of the seizures, contributing to neurodevelopmental delays and making it more likely the infants will suffer long term epilepsy. The technology to be developed under this project will provide easy to apply, dry electrode EEG equipment that does not break the neonate’s skin. Accordingly, the team will develop an innovative Neonatal EEG MOnitor (“NEMO”) system intended as a reliable and easy-to-use EEG system that will increase availability of neonatal EEG monitoring at all hours of the day and to hospitals that typically lack this capability. NEMO leverages QUASAR’s innovative dry sensor technology that has been demonstrated to record high fidelity EEG signals that are immune to electrical artifacts, without the need for skin abrasion or the use of conductive gels.

    QUASAR presents at the IDGA UAV Summit West
    San Diego, CA, USA. November 7, 2011
    QUASAR 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, 2011
    One 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.
