Stock was originally USHG and was renamed IOTN.  The company is said
to be or has developed a system that can stop a car or other moving
vehicle such as airplane.  The products would aid in fight against
terrorism.  They received a 9 million dollar contract from the
Government and relocated to Stennis in Mississippi.  The stock has
dropped and information about the company is hard to get.  People are
saying the company is a scam and that Stennis is a broken-down place
hardly the place for a going productive business.  Schwab took my
money for the stock and now it is listed as a numerical number in my
account and I am told there is no information.

You are sure about the stock name , since it is stock from US Home and Garden
