Title: Asset recovery device
Inventor: BOWEN JAMES THOMAS
IPC: G08B13/14
Filed: 2003-10-09
Abstract: A system is presented for a novel apparatus and method that shortens the time that an asset is lost and increases the probability of return should the asset go astray. The system is intended to allow the asset to proactively alert passers-by that it is lost and also alert the owner of the asset that the asset is lost. The invention contains identification and contact information to aid in the safe, prompt return of the asset. The system comprises an asset tag that is attached to the asset and a base station that is 'synchronized' with a the asset tag at specified intervals.
