Sometime in the last 4 months or so, I lost my tiny but expensive iPhone Bluetooth Headset. Now, a little late, Apple files a patent:
[The filing] describes a method and system for locating objects using Bluetooth, such as the tiny Bluetooth Headset it sells for iPhone that almost everyone has lost in the crease of their couch or car seat one time or another.
Similar to the discovery feature of traditional cordless phones, the concept would allow iPhone users to ping paired Bluetooth devices, which could then emit a high pitched sound or light.
Again, however, Apple takes the concept a bit further by suggesting that it could also sell and market a tiny Bluetooth device that could be attached to almost anything, from a set of keys to a household pet, that would similarly aid in locating those objects in the event they become lost. An interface on the iPhone (master device) could manage several of those devices (slaves) at once, according to the filing. [AppleInsider]
Hmm. I wonder if I looked in the couch cushions?
