Abstract: A method of calculating blast injury metrics in a weapon training/IED blast scene can include: reconstructing topological layout of the scene having at least one real subject and a blast source; obtaining anthropometric and posture data for each real subject; obtaining anatomical soldier model for each real subject; identifying real position of at least one real pressure sensor on each soldier during a blast; positioning a virtual sensor on each anatomical soldier model to correspond with real pressure sensor on the real subject; calculating weapon signature of the blast source, the weapon signature including pressure versus time for a blast from the blast source; generating simulated pressure traces on each anatomical soldier model at east virtual pressure sensor; calculating blast injury metrics for the at least one real subject; and generating a report that includes the blast injury metrics for the at least one real subject.

Abstract: A personal extraction cart for supporting and restraining a person to facilitate movement of that person from an extrication point, wherein the cart includes a frame having a support surface. The support surface has upper and lower faces and a leg support portion and a back support portion defining a longitudinal length with oppositely disposed longitudinal edges. The leg and back support portions have a use position in which the upper faces of each of those portions are angled relative to each other along the longitudinal length of the frame. Wheels are preferably attached below the support surface for facilitating movement of the cart in its transportation position.
