Re: Private baby GPS

Arn't the ultrasonic sensors directional ?
If you want to find how far away a kid is, don't you kneed to know were
it is
What about it's body obsuring the line of sight ?
What about signals boucing around ?
Wind speed was mentioned, but what about temperature effects ?

Laser is alot more accurate I guess, but directional.

It's would be great if we could hi-jack GPS chips for down to earth
sensing.

Maybe we shouldn't use kids, it's getting creepy. What about fluffy
kittens ?
