The last time we talked about inventions I discussed my idea for license plates with EZ-Passes built in, a rolling suitcase that turns into a chair and a pillow for couples trying to watch TV on a couch. This time I have three new inventions and no big intro story because I kind of blew the one invention-related anecdote I had on that first article. Anyway, hopefully you can still enjoy the ideas without a long-winded introduction.
