Vertical Linear Accelerator for Dynamic Visual-Vestibular Acuity Health Status Evaluation and Desensitization Training

Mitigating Spatial Disorientation (SD) events is of particular interest to the military due to the severe repercussions of such events during flight or in general task performance for certain non-flight activities. Researchers have determined that these events could be mitigated by screening aircrew and other critical staff for visual acuity problems using a vertical oscillating motion system. The SHOT Vertical Linear Accelerator (VLA) system utilizes cutting-edge technologies to provide a safe, human-rated motion system operated via a user-friendly interface and running any desired motion profile within the defined design constraints. SHOT's VLA system is packed with the latest technologies. SHOT's proposed solution utilizes linear motor and servo controller technologies to provide a scalable vertical oscillation capability that can achieve 12 feet or more of displacement with peak accelerations up to 1-g. SHOT's solution incorporates the latest in multi-zone safety alarm and restraint systems to ensure personnel safety. A high-resolution programmable optotype display is included for visual acuity testing and for use with motion sickness desensitization protocols. SHOT mastered these technologies as part of previous experience developing vestibular test equipment for university research. The SHOT VLA system is the next generation of advanced hardware for visual acuity and vestibular testing.
