As Hugo helpfully commented in a previous post, here is the link to the Power Monitor Patent. The specific page I’m linking to is the Packet model. Lots of reading to do here, but its pretty interesting.
One of the things I find most interesting about this patent is the citations dating back to 1977. Definitely not a cutting edge technology we’re working with here. If the 1977 patent was the byproduct of the ’70s energy crisis what inventions will we see as a byproduct of our current energy phase?
