Saw this patent application in Digg. I'd like to dispute it. If you read the "Claims" section, you'd realize that this guy was abducted by aliens (happens to all of us) and they deposited him at a distance down the street calculated from his walking speed at the time of the abduction and the amount of time it took to probe him. All that other stuff about constructing the device is just kruft the aliens implanted in his brain.
Seriously, this should have been filtered out of the process early on, not posted on a ".gov" site. I'm starting to agree that the patent process needs a bit of review.
