Abstract

An owner oriented system for locating lost or stolen property comprising a GPS module, micro computer, a modem and a phone installed in a vehicle; regularly and automatically computing position data; and, under control of a program, storing novel position data in a buffer and downloading upon proper request from an incoming call.

Claims

1. An owner oriented system for locating lost or stolen property, comprising:

(a) powering up a GPS module including a receiver, an antenna and a GPS computational and communications unit operatively connected within a vehicle to a microcomputer attached to a memory having a buffer and a modem attached to a mobile phone; and

(b) regularly and automatically receiving GPS signals through the antenna into the GPS receiver and computational and communication unit;

converting the signals to position data;

(c) regularly and automatically testing for availability of position data from the GPS module through control of an activated program in the microcomputer;

(d) testing position data for novelty;

(e) queuing in a memory buffer novel position data;

(f) regularly and automatically testing for an incoming call through the mobile phone;

(g) testing an incoming call for a password and a vehicle position request; and

(h) serially downloading contents of a buffer upon the detection of the password and a position request.

2. The system of claim 1 that includes, through control of the activated program:

initializing the modem, including setting auto-answer, baud rate and register bit format;

initializing the GPS module; and

initializing a memory buffer.

3. The system of claim 1 wherein the microcomputer and memory comprise a PC.

4. The system of claim 1 wherein testing position data for novelty comprises testing the data for deviation from prior data cued into memory by an amount greater than twice an average estimated error for GPS measurements.

5. The system of claim 1 that includes generating an incoming call from a remote PC computer attached to a modem and a phone.

6. The system of claim 1 wherein receiving signals includes using an antenna comprising a thin capacitor.

7. The system of claim 1 that includes, through control of an activated program,

testing an incoming call for a reset password request;

and

updating a password used in a password test.

8. The system of claim 1 that includes associating a clock time with each position data cued into the buffer.

9. The system of claim 8 that includes associating a date from a clock attached to the portable computer with position data cued into the buffer.

10. The system of claim 1 wherein the vehicle comprises an automobile and a power source for powering up comprises an automobile battery.
