Head-Lock Mount for Advanced Night Vision Goggle (NVG)

Diffraction LTD proposes to develop a novel occipital head-lock system to support advanced night vision goggles (NVG) used by Air Force personnel not wearing typical aviation or combat helmet. Phase I efforts will demonstrate the feasibility of a lightweight, direct head mount that maintains optimal NVG performance in the absence of a helmet, minimizes user fatigue, and reduces the risk of injury. Designs will focus on derivations of an occipital head-lock system with fine adjustment that ensures stable alignment of NVGs under variable conditions, is compatible with existing communication systems and specialty head-gear, i.e. chem.-bio masks/hoods, etc, and demonstrates reduced potential for torque-jolt. Using finite element analysis and human biodynamics software we will evaluate newer, lightweight materials to be used in place of bulky metal components, optimize hinge points and brackets to reduce weight and improve stiffness, and adjust designs to provide optimal fit and comfort across a broad range of users. This device will provide a superior mechanism for employing NVGs without helmets in both static and dynamic work settings, while minimizing stress and fatigue on a user’s head and neck.
