Looking for interferometer for location detection

I’m still working on this a project where I want to find and continue to know the location of 10 robots moving up to 10kph in a field about 100 yards square with 0.2-1.0 meter accuracy. RFID-Radar is -almost- a solution in a box except that it takes many seconds for it to do range-finding.

GPS isn’t accurate enough.

I’m now envisioning 2 sets of antennas using angle of arrival interferometry. I’ve been googling (and the library) my head off and not coming up with too much thus far. Do you know of an interferometry system that might detect 0.1 degree difference or so? I figure that with 2 sets, one on the X plane, one on the Y, we can get an accurate location. I’ll ping the RFID-Radar guy on this but I think he’s focused elsewhere.

Tourettes

There was a guy in an SBA class a couple nights ago that had Tourettes Syndrome. I had seen documentaries about it but never met someone with it. It must be a horrible way to go through life.

He was sitting about 20′ from Charlotte and I. At first, it sounded like he was using a cell phone while in class. He’d say something quietly every couple seconds. I listened closer and could tell that, in general, he was occasionally echoing the words of the speaker.

Whenever he looked around the room, especially if he made eye contact with someone, he’d say something… like the kind of thing you might think for a split second if you were looking around, nervous at a party. Things like, “Don’t look at me!”, “What are you looking at?”, “What’s your problem?”

He’d sometimes feed off his own words and actions. At one point, he made eye contact with Charlotte and started scratching his eye with his middle finger trying to “subtly” give her the finger. The scratch grew into a spasm. The spasm grew into thrusting his finger across his face repeatedly and forcefully such that he was just as likely to hurt himself as insult Charlotte.

He made many people in the classroom very nervous. Several people left. Someone suggested that he was schizophrenic.

I couldn’t imagine how sucky my life would be if I had no choice but to voice every emotional thought I had. There aren’t any very effective treatments for this one in a million disorder.

Want to be in a Movie?

I got this email just today. You might be interested. It’s a movie casting call in Boston. Warren is a friend of mine. This is his second film. His first was certainly completely odd… think Toxic Avenger. It looks like his second is shooting for oddness as well. Though more polished (maybe). With luck, think Evil Dead….

Straight to DVD feature B horror comedy “Snurg Hunter”, budget $150,000, shooting this summer (July-Sept) 2007 in greater Boston. We have guaranteed distribution via our last feature “Pony Trouble”, and so when finished, “Snurg Hunter” will be in stores nationally and internationally. Hopefully with your name in the credits :)
