Hmmm... Gathering ideas for things to invent? ;-) Do the ones that think of them get a residual? How 'bout inventing bed sheets whose corners NEVER pop off? Pillow cases for hospital beds that NEVER fall behind your back (no velcro where you lay), or home-test kits to check for ALL kinds of bacteria?

That's easy! I. Remote-control paging: 1. If you lost a remote control to your TV, VCR, DVD Player, and anything that uses a remote, press a "Page Remote" button on the set, player, base-station, et al. and the remote will sound a finding alarm. Then the user will walk to the source and find it. II. Key paging: 1. If you lost your keys- nowadays, keys also have buttons, fobs, et al. that have some sort of electronic circuitry in them and some kind of noise emitter. Perhaps a "Page Key" button could be installed in an inconspicuous area of the vehicle (like on the roof of one, or atop the recessed area of the trunk hatch that carries your license plate.) 1a. Or a separate keypager accessory could be purchased and is meant to be put someplace visible in your house. For example- BMW could also sell you a BMW wall clock (Pontiac already sells wristwatches) that is wirelessly bonded to your key/key-fob. On the wall clock would be a "Page Key" button, of course. 1b. If you've lost your keys elsewhere, your car manufacturer can sell a premium-quality electronic wristwatch that also has a key-paging function! (More to come, perhaps.)

A flying machine. Leonardo Di Vinci had the blue prints but never had the time to build much of what he had drawn.
