Wireless sports safety biosensors preventing the risk of heat stress

Hall Ryan Laboratories Inc. is a research & development company specializing in portable biosensors for industrial and sports safety. The company has adapted proprietary medical technology (typically used to monitor patients) for use in industrial, military, police, and fire safety applications. Although the company has not yet produced commerical products beyond research and development, we have high expectations of releasing an upgraded version of our Thermal Sensor Mouthguard design for monitoring heat stress during summer football practice very soon. Please check us out from time-to-time to see our progress.
