    • Conductive concrete mixtures are described that are configured to provide EMP shielding and reflect and/or absorb, for instance, EM waves propagating through the conductive concrete mixture. The conductive concrete mixtures include cement, water, conductive carbon material, magnetic material, and metallic conductive material. The conductive carbon material may include conductive carbon particles, conductive carbon powder, and/or coke breeze. The metallic conductive material may include steel fibers, and the magnetic material may include taconite. The conductive concrete mixture may also include supplementary cementitious materials (SCM). A method of making a concrete structure includes pouring a concrete mixture to form conductive concrete, and positioning a first conductive screen within the conductive concrete proximate to an exterior surface of the conductive concrete. The method also includes positioning a second conductive screen within the conductive concrete in electrical contact with the first conductive screen.

    • The present disclosure is directed to a system and method for surgical training with low cost, reusable materials and a highly customizable virtual environment for skill-building. According to various embodiments, a surgical training tool is usable in conjunction with a support structure configured to at least partially constrain the tool movement. Meanwhile, the tool is tracked in real-time with off-tool detectors to generate a tool path driving a virtual rendering of the surgical training tool in an operative environment. The virtual rendering may be visually observable via a display device and may include a customizable and/or selectable operative environment with one or more structures that can be operated on by the virtual surgical training tool. By tracking the virtual tool interaction with the virtual structures, a task path may be established for documenting and/or objectively assessing the performance of one or more operative tasks.
    • 本公开涉及一种用于外科训练的系统和方法,其具有低成本,可重复使用的材料和用于技能培养的高度可定制的虚拟环境。 根据各种实施例,外科手术训练工具可与配置成至少部分地限制工具运动的支撑结构一起使用。 同时,使用工具外检测器实时跟踪该工具,以产生在操作环境中驱动外科手术训练工具的虚拟呈现的工具路径。 虚拟渲染可以通过显示设备在视觉上可观察到,并且可以包括具有一个或多个可由虚拟外科手术训练工具操作的结构的可定制和/或可选择的操作环境。 通过跟踪与虚拟结构的虚拟工具交互,可以建立任务路径用于记录和/或客观地评估一个或多个操作任务的性能。
