Combatant Security Expert System software covers biomechanical and biochemical load assessment of aircraft pilots and land personnel wearing heavy helmets mounted with various sensing devices, and design of mitigation measures. The software is used to address the following issues:

  • Systematic investigation of the mechanisms underlying neck pain and tissue damage. Software is used for design of neck support and other protection devices.
  • Use of an integrated modeling framework to assess required neck support levels and neck support architectures. This allows the designer to properly configure and optimize concepts by simulating and quantitatively investigating various loading conditions of candidate head/neck/helmet/support systems.
  • Dynamic modeling of prototype neck support devices for studying the effects on the cervical complex of various support strategies.

Due to its flexible and modular architecture, Combatant Security Expert System can be expanded with supplementary modules that enable the modeling and design of other combatants' medical and military oriented devices for a variety of applications.

Combatant Security Expert System software has been developed using ESI Security Technology's proprietary Expert System Integrated Development Environment (ESIDE®) that enables seamless integration with AutoCAD design environment, Dymola/Modelica modeling framework, fuzzy logic solver, and other critical features. Software allows high-fidelity neck/head/helmet system visualizations, dynamic animations of the head and neck motion, optimal design on neck protection devices, and seamless data integration with parameterized mechanical assemblies prototyped in AutoCAD. User-friendly graphical dialog windows allow the user to input simulation parameters and control the overall process.

The integrated model used in the software can characterize complex head and neck dynamics, calculate the distribution of stress and strain in the neck tissues, and determine the complex impact of the stress on tissue structure and function, including forces developing in the loaded neck discs.
