Relative positioning system and method
First Claim
1. A relative positioning system comprising:
- an article wearable by an operator;
at least two radio signal receivers positioned on the article spaced apart around the operator wearing the article such that the operator causes signal interference with a radio frequency signal detectable by each receiver, the radio frequency signal being associated with an emitter;
control electronics on the article operatively coupling the spaced apart receivers and configured to determine a direction of the emitter relative to the operator based on the signal interference relative to the human body; and
a plurality of stimulus generators supported by the article operatively connected to the control electronics and to the operator wearing the article, each stimulus generator able to generate a stimulus perceptible to the operator wearing the article; and
the control electronics activating one of the plurality of stimulus generators so as to provide a direction cue to the operator as to the direction of the emitter relative to the operator.

Abstract
A relative positioning system and method has an adjoining pair of spaced apart receivers positioned proximal to an object causing a signal interference with a radio frequency signal detectable by each receiver of the adjoining pair. The radio frequency signal is associated with an emitter. Control electronics operatively couple the spaced apart receivers. The control electronics are configured to determine a direction of the emitter based on the signal interference. In an embodiment of the system and method the emitter is associated with an object of interest, the signal encodes information relating to the identity and status of the object, and information and heading of the object are cutaneously communicated to an operator by an article worn by the operator.

15. A method for achieving operator awareness of a casualty in an emergent environment, the casualty having a heading with respect to the operator and emitting a signal having a strength, the method comprising the steps of:
-
positioning on the operator a wearable article supporting a two-dimensional, body-centered coordinate system formed by a plurality of receivers and a plurality of stimulus generators, each receiver of the plurality of receivers able to receive the signal from the casualty, each signal generator of the plurality of stimulus generators able to generate a stimulus perceptible to the operator, the plurality of receivers operatively coupled to the plurality of stimulus generators by control electronics; detecting with the plurality of receivers the signal emitted by the casualty; determining the heading of the casualty in the body-centered coordinate system; and communicating to the operator a directional cue corresponding to the heading, the directional cue generated by one stimulus generator of the plurality of stimulus generators. - View Dependent Claims (16, 17, 18)
