Yeesh, lighten up! You think it's impossible that Heon could be involved
in something legitimate (or at least legal?)

Example: I understand that at one point the State of Texas was beta-
testing an "automatic speeding ticket" system. The setup was basically
a doppler radar like the police use, with a (video?) camera, set up
in a secure box on the side of a highway. You drive by at excessive speed,
the radar detects you, the camera gets a picture of the rear end of your
car - your license plate in particular.. and you get a ticket in the mail
a week later.

Say, I wonder if you could get accurate enough velocity information from
successive frames of a video tape, to do this without the radar? Whoops!
Better get my patent applications out!

Incidentally, the Texas system was shelved. It seems the equipment suddenly
started experiencing catastrophic failures. Something to do with large
holes or tight clusters of smaller holes in the outer boxes...

I love Texas :-}
