Abstract
Abstract A close-fitting garment has a pattern of tactile stimulators arranged on surface. The stimulators can be selectively energized from some remote point in accordance with threats to a person wearing the garment. The stimulators are controlled by a radio receiver fed by a radio transmitter. The relative position of an energized stimulator on the garment is indicative of the relative position of the threat to the wearer. Frequency or amplitude of the stimulator can be used to give information such as threat speed or relative danger.

A tactile target alerting system for a person; including a close-fitting garment for the person; a circle pattern of sensation producing means in the surface of said garment; a plurality of filter means each passing a different frequency individually connected to said pattern of sensation producing means for selectively energizing said sensation producing means; a plurality of oscillator means equal in number to said filter means; switching means connected to said oscillator means so as to selectively energize desired ones of said oscillator means; connecting means connecting said oscillators to said filter means; control means connected to each oscillator so as to variably control the power output of said oscillator; and power means connected to said switching means to provide power for said oscillators.
