Stock locator system using GPS translator
First Claim
1. In a global positioning system (GPS) including satellites orbiting the earth and transmitting positional information signals, a system for locating a lost article comprising:
- a mobile encoder transmitter/receiver device for transmitting a coded identification signal specifically corresponding to an identification number associated with a particular lost article,a decoder transmitter/receiver device affixed to said particular lost article, said decoder transmitter/receiver device being activated in response to said coded identification signal from said mobile encoder transmitter/receiver device to receive positional information signals from said GPS and to re-transmit said positional information as alternate, frequency shifted GPS positional information signals,wherein said mobile encoder transmitter/receiver device receives said alternate, frequency shifted GPS positional information signals re-transmitted from said decoder transmitter/receiver device and said positional information signals from said GPS to determine the position of said particular lost article.

Abstract
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.

15. A method for locating a lost article, comprising the steps of:
-
transmitting a coded signal from a local encoder transmitter, to a decoder receiver, said coded signal representing an identification number designating said decoder receiver to actuate said decoder receiver, said decoder receiver being located in the proximity of said lost article; translating a GPS positional information signal into a modified frequency; and determining a location of said decoder receiver by comparing said modified signal in said decoder receiver to a direct GPS signal. - View Dependent Claims (16, 17, 18, 19)

20. A method using a global positioning system (GPS) including satellites orbiting the earth and transmitting positional information signals, a system for locating a lost article comprising the steps of:
-
Step 1. transmitting from a mobile encoder transmitter/receiver devices a coded identification signal specifically corresponding to an identification number associated with a particular lost article, Step 2. receiving said coded identification signal in a decoder transmitter/receiver device affixed to said particular lost article, Step 3. activating said decoder transmitter/receiver device in response to said coded identification signal from said modible encoder transmitter/receiver device, Step 4. receiving positional information signals from said GPS, Step 5. re-transmitting said positional information as alternate, frequency shifted GPS positional information signals, Step 6. determining the position of said particular lost article by receiving said alternate, frequency shifted GPS positional information signals re-transmitted from said decoder transmitter/receiver device and said positional information signals from said GPS.
