Our invention looks like an eye on a belt.  The pupil is an e-nose sensor that detects the smell of all
mammals and a few reptiles.  A microprocessor memory bank in the left side has compass software
and a distance finder.  The distance finder works by the amount of smell and approximately how far
away the animal is.  There is an alarm that tells what animal it detects and what direction and
distance it is.  For example, if you are hiking and a poisonous snake is nearby, the e-nose will pick
up its scent.  The automatic alarm tells you rattlesnake, twenty-feet northwest.  This alarm gives you
enough time to get out of the way.  The detector works by a battery that is behind the e-nose
sensor.  There is a warning low-battery light, because you want to know if the batteries are running
