1. A communication system, comprising:
- an emitter that emits an infrared signal having a selectable signal pattern comprising changing energy levels having at least a first energy level and a second energy level;
a receiver that receives said infrared signal;
a processor operationally attached to said receiver and that analyzes the received signal detect a pattern of changing energy levels;
a display device that displays a visually discernable output indicating the presence of said signal if the pattern of said signal is recognized; and
,said processor further comprising an analysis module that compares each pixel of output from said receiver to the same relative pixel from a previous frame and/or to surrounding pixels in order to determine a pattern of changing levels between distinct levels of infrared energy.

Abstract
A communication system and method utilizing an infrared signal emitter communicating a predefined signal, and an infrared signal receiver capable of receiving such predefined signal, distinguishing such predefined signal within a field of view of the infrared signal receiver, and providing output indicating the location of the infrared signal emitter within the field of view of the infrared signal receiver.

5. A method of communication, comprising:
-
providing an emitter that emits an infrared signal having a selectable signal pattern comprising changing energy levels; providing a receiver that receives said infrared signal and a processor operationally attached to said receiver; analyzing the received signal to detect a pattern of changing energy levels; and displaying an output indicating the presence of said signal if the pattern of said signal is recognized; receiving said signal; collecting image data from each frame on a pixel-by-pixel basis. comparing each pixel of output from said receiver to the same relative pixel from a previous frame and/or to surrounding pixels; determining a pattern of changing levels between distinct levels of infrared energy; and marking said pixel if a pattern is found. - View Dependent Claims (6, 7, 8)
