Smart, Rapid-Response Jettison for HMDS

Cornerstone Research Group Inc. (CRG) proposes to develop a self-contained system that can distinguish an ejection from normal operations, and respond appropriately by dismounting the HMDS from the crewmember’s helmet only during an ejection. CRG has determined that using stimuli that are unique to an ejection will be more reliable and faster than using acceleration. Optimum environmental stimuli were determined in Phase I that when used in combination are unique only to an ejection, and are an ideal way to differentiate an ejection from ACM. This system, in line with a lightweight microactuator release, will provide a reliable, compact solution. CRG’s smart system will be self-contained, requiring no aircraft modification and operating from its own long-life battery. It uses a combination of stimuli and ejection event features to minimize false positive releases. The system is also small, lightweight, and low profile with electronic components less than one-half inch in size. CRG’s system will also be designed for compatibility with the range of relevant fielded helmets and night vision goggles (NVG), such as the HGU-55/P and MACH, used with NVG by ITT Night Vision. BENEFIT: Operational Benefits: Reduction of injury during ejection when using HMDS; Elimination of unwanted release during combat maneuvers; Requires no aircraft modification; Releases HMDS quicker, reducing injury threat to pilot. Commercial Applications: Machine guard safety switch; Smart personal safety equipment
