SIMBEX ANNOUNCES THE INTRODUCTION OF HEAD IMPACT TELEMETRY (HIT™) TECHNOLOGY
IN ICE HOCKEY

The HIT System™ successfully records the first measures of head impacts in ice hockey during games and practices with a goal of better understanding concussions and how to reduce their frequency.

Lebanon, NH - November 15, 2005 - Simbex LLC announced that it has developed an ice hockey HIT System™ that will be used in a joint study with Dartmouth Medical School (DMS) and Dartmouth Hitchcock Medical Center (DHMC). The HIT System™ incorporates advanced sensor and telemetry technology that is fitted in the player's helmet to provide vital, real-time, hit-by-hit information about the head impacts player are receiving during games and practices and transmits them rink side. The technology is now practical enough that all the players on a team can be monitored simultaneously. Until now this groundbreaking technology was only available for football helmets. By instrumenting ice hockey helmets with the patented HIT technology, Simbex has successfully recorded the first measures of head impacts in ice hockey.

"This development for ice hockey marks the next progression for Simbex and the expansion of HIT System™ technologies. For the first time we have data from multiple helmeted team sports," said Richard M. Greenwald, Ph.D., founder and President of Simbex. "Furthermore, the success of the ice hockey system demonstrates the feasibility of instrumenting various other helmets for sport, industrial or military uses."

The ice hockey version of the HIT System™ was developed for use in a pilot study together with the Dartmouth Hitchcock Medical Center, the Dartmouth Medical School, and the Dartmouth College Department of Sports Medicine. Five members of the Dartmouth College men's ice hockey team will be wearing instrumented helmets throughout the season. The data from these helmets will be analyzed by biomechanists and equipment developers at Simbex, and combined with clinical data including functional MRI scans and neuropsychological assessments of the players collected by Dartmouth researchers led by psychiatrist Tom McAllister, Ph.D., neurosurgeon Ann-Christine Duhaime, M.D., and neuropsychologist Arthur Maerlender, Jr., Ph.D. "The goal is to better understand the cause of concussions and the effects of sub-concussive impacts on cognitive function in order to provide better medical care for those with brain injury," said McAllister.

The HIT System™ is not only a research tool, but it has a real-world, practical benefit of being able to monitor players for head impacts that may have gone unnoticed by alerting the medical staff at the instant the impact occurred with an alarm on a pager that is worn by the team medical staff at rink side. "The system is an extra set of eyes on the ice," said Jeff Frechette, the head athletic trainer at Dartmouth who will be responsible for the daily operation of the system. "Especially in ice hockey it can be hard to tell whether a player took a hard impact to the body or to the head and the rigidity of the ice and the boards is incomparable to anything in football."

Simbex and Dartmouth received valuable support from Reebok and Riddell. Riddell is currently marketing the HIT System™ in its football helmets under the name of the Riddell Sideline Response System™ (SRS™). Simbex and Riddell have been working together to commercialize HIT™ technology and to use the information that the data collected to reduce injuries in football through product innovation.
