Stock locator system using GPS translator |
摘要 |
A device which is useful in locating lost articles including a GPS translator, located in close proximity of said lost article. The GPS translator is capable of translating a frequency transmitted from a GPS transmitter to a GPS receiver, the GPS receiver is capable of receiving a first signal directly from the GPS transmitter, and a second signal transmitted from the GPS transmitter, through said GPS translator, to the GPS receiver. Since the translator typically uses considerable energy during continual usage, there is a power management portion included which actuates the translator only during those times that a coded signal is transmitted to the translator, which is typically transmitted by the user who is attempting to located the lost article.
