Appl. No.:

11/053712

Inventors:

David Randall - Springfield VA, US

Abstract:

For a helmet-mounted imaging system to be multi-purpose, effective, lightweight, and easy to use, it must be designed with the most advanced technologies, interchangeable and expandable for future upgrades. The Interchangeable Donut Helmet concept achieves this ability through the use illustrated in FIG. of Section . These connected modules are attached around the perimeter of the helmet. An adjustable tensioner insures compatibility and a snug fit on similar helmets (FIG. ). Each donut module is designed for a different use such as imaging camera, battery source, global positioning, or wireless transmitter. Images are transmitted wirelessly via radio frequencies (RF) (FIG. ). A Helmet-Mounted Display (HMD) is incorporated on the front donut module in order for the wearer to view the camera image (FIG. ). Each donut module consists of subsystems that incorporate low cost, lightweight and low power technologies. This provides the realization of a head-borne, low power and cost effective imaging system. Modularity promotes interchangeability that is simple and capable of various system configurations depending on the task. This system concept has firefighter and military applications.
