Joe Grand says that the information coming out of the badge is pseudorandom (which doesn't really explain why it repeats with a period of less than a minute, but maybe his pseudorandom number generator is not so great).
I completed my training and have become a San Francisco Neighborhood Emergency Response Team volunteer. If you live in the Bay Area, you too can get trained for free; there are lots of other similar programs around the U.S., so, if you live in the U.S., you can probably find one in your area.
I also got a stylish safety vest and hard hat!
