QUASAR Awarded NIH Grant to Help End Addiction
San Diego, CA, USA. September 30, 2019
QUASAR has been awarded a research grant from the NIH through The Helping to End Addiction Long-term Initiative, or the NIH’s HEAL Initiative. Initial awards from the $945 million program were announced at the end of September. The NIH HEAL Initiative aims to improve treatments for chronic pain, curb the rates of opioid use disorder and overdose and achieve long-term recovery from opioid addiction. QUASAR’s award is one of 375 grant awards across 41 states made by the National Institutes of Health in fiscal year 2019 to apply scientific solutions to reverse the national opioid crisis.
QUASAR’s project, described here, aims to create a Neurofeedback solution in Virtual Reality (VR) that will provide an alternative to pharmacological pain relief. QUASAR’s non-invasive dry electrode electroencephalography (EEG) technology will be integrated with VR-based neurofeedback protocols. This Neurofeedback EEG in VR (NEVR) system will train specific brain networks through neuroplastic reinforcement to reduce pain sensation. In this Phase I effort, a clinical trial to demonstrate the feasibility of this method will be conducted at the University of California at San Diego (UCSD) on patients suffering from chronic pain.
QUASAR Awarded $125k NASA Phase I SBIR Contract
San Diego, CA, USA. August 19, 2019
Long-term space missions can be physically and mentally stressful on the crew, which may require physiologic monitoring. NASA has just awarded $125K Phase I SBIR research contract to Quantum Applied Science and Research (QUASAR) to develop a system to identify Individualized, Noninvasive Speech Indicators for Tracking Elevations in Stress (INSITES). The goal of INSITES is to develop an unobtrusive, objective, and reliable detector of stress that measures changes in speech and vocalizations from audio recording equipment (microphones, communications systems, computers) used on spacecraft during operations, without requiring additional sensors or dedicated processing hardware. Under this project, QUASAR and the Florida Institute for Human and Machine Cognition (IHMC) will extract features in speech related to stress from audio streams and process these through artificial intelligence algorithms to classify stress in real-time. The project technology will enable NASA to continuously assess crew stress levels and intervene before increased stress adversely impacts mission safety, effectiveness, or success.
QUASAR awarded STTR program for development of an EEG+tDCS headset
San Diego, CA, USA. April 26, 2019
QUASAR has received a contract from the Air Force’s STTR program for a project to develop a Closed-Loop Feedback Control for Transcranial Direct Current Stimulation.
Because of rising demand for human analysts and more efficient processing of increasingly large and challenging amounts of intelligence, human limitations on mental workload, cognitive fatigue, and attention or task engagement, need to be accurately monitored in real-time in order to provide sensitive detection of impaired cognitive states. It is a challenge to continuously monitor these cognitive characteristics, known collectively as dynamic brain information processing capacity (dBIPC) to implement real-time mitigations in a closed-loop feedback system.
The overall goal of this Phase I STTR project is to design a closed-loop feedback system that incorporates advanced EEG monitoring systems, brain-state classification algorithms and real-time gauges of mental workload, fatigue, and engagement, and a low-noise, high definition tDCS (HD-tDCS) system.
Quantum Applied Science and Research (QUASAR), Inc. will contribute advanced dry-electrode electroencephalography (EEG) sensors with proprietary real-time brain state classification algorithms, while the Institute for Human & Machine Cognition (IHMC) will incorporate modeling techniques from leading experts to determine optimal stimulation parameters for alleviating cognitive impairments, and Soterix Medical, Inc. will provide a transcranial direct current stimulation (HD-tDCS) system and necessary expertise to integrate it with the other components.

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

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.
