Design of a Low Power Embedded Microprocessor for a Hands-Eyes-Ears-Free Personal Navigation and Communications System

摘要

This thesis details the engineering design of a personal, computer- based system. which is intended to support a hands-eyes-ears-free Personal Navigational and Communication System (PNCS). This computer-based system is designed to be used with COTS devices, such as, (1) a GPS receiver, (2) a laptop or desktop computer, (3) a rechargeable, long-life battery pack, and (4) a wearable tactile communications vest. The vest is currently under development by the Naval Aerospace Medical Research Lab (NAMRL) and together with this computer-based system can provide a complete hands-free personal navigational and communication system. The intent of the navigation system is to satisfy both commercial and milita uses for land-based edestrian and vehicular travel.
