Description

To address the Navy"s need for a blast dosimeter, Physical Optics Corporation (POC) proposes to develop a new wearable omni-directional blast dosimeter (OMNIBLAS) for accurate blast pressure monitoring. The miniature badge-like dosimeter (~2 in. x 1 in. x 0.5 in., 6 oz) consists of a miniature direction-insensitive blast sensor and a low-power processing board with an embedded pressure-acceleration decoupling algorithm for accurate blast pressure measurements. The innovation in the integration of a pressure sensor and advanced signal processing will enable the OMNIBLAS to accurately measure blast pressure while mounted on a warfighter. The OMNIBLAS technology will allow the USMC to accurately sense, measure, and store blast exposure levels warfighters face using a low maintenance lightweight device. As a result, this device offers long-term monitoring and documenting of blast exposure for Breacher and route clearance personnel, which directly address the Warfighter PPE EOD ensemble requirements. In Phase I, POC will demonstrate the feasibility of OMNIBLAS by design, simulation, and testing of the pressure sensor. POC plans in Phase II to integrate the components into a prototype suitable for independent field testing by the Navy.
