Wheel-mounted tire pressure gauge

Another great idea, constant tire pressure monitoring---but a worthless patent because it doesn't protect the idea, only very specific embodiments of it. And these inventors thought of lots of versions of their embodiments and included 30 figures. I've only included part of them here along with the full list of brief descriptions. But still all you have to do is look at the prior art and you'll find many simpler solutions (which may, or may not, be on the market).
