Magnetic vector sensor positioning and communication system
A system is described herein for monitoring the movement of one or more magnet sources located external to a device using the vector data from one or more magnetic vector sensors incorporated in the device to determine a position and/or to communicate information.
1. A system comprising:
a first device comprising a screen and at least one vector magnetic sensor that senses the magnetic field produced by the Earth;
a second device comprising a modulating magnetic source, said first device is configured to utilize the at least one vector magnetic sensor which interfaces with the modulating magnetic source in the second device to obtain vector data, said vector data corresponding to information communicated from the second device to the first device;
wherein said information comprises an identifier; and,
wherein said first device is configured to use said identifier with a location look up table.
2. The system of claim 1 , wherein the information is location information corresponding to a location of said second device.
3. The system of claim 2 , wherein said location information comprises a latitude and longitude of said second device.
4. The system of claim 2 , wherein said location information comprises an altitude of said second device.
5. The system of claim 1 , wherein said first device comprises a compass.
6. The system of claim 1 , wherein said first device comprises an accelerometer.
7. The system of claim 1 , wherein said modulating magnetic source comprises an electromagnet.
8. The system of claim 1 , wherein said first device is configured to determine a presence of said second device.
9. The system of claim 1 , wherein said first device is configured to use the information for authentication purposes.
10. The system of claim 1 , wherein said first device is configured to interpolate a location based on said information.
11. The system of claim 1 , wherein said first device is configured to extrapolate a location based on said information.
12. A system comprising:
a first device comprising a screen and at least one vector magnetic sensor that senses the magnetic field produced by the Earth;
a second device comprising a modulating magnetic source, said first device is configured to utilize the at least one vector magnetic sensor which interfaces with the modulating magnetic source in the second device to obtain vector data, said vector data corresponding to information communicated from the second device to the first device; and
a third device comprising a modulating magnetic source.
13. The system of claim 12 , wherein said second device and said third device have at least one different magnetic characteristic.
14. The system of claim 13 , wherein said at least one different magnetic characteristic comprises a different throw.
15. The system of claim 13 , wherein said at least one different magnetic characteristic comprises a different amplitude.
16. The system of claim 13 , wherein said at least one different magnetic characteristic comprises a different directionality.
17. The system of claim 13 , wherein said at least one different magnetic characteristic comprises a different coding.
18. A system comprising:
a first device comprising a screen and at least one vector magnetic sensor that senses the magnetic field produced by the Earth;
a second device comprising a modulating magnetic source, said first device is configured to utilize the at least one vector magnetic sensor which interfaces with the modulating magnetic source in the second device to obtain vector data, said vector data corresponding to information communicated from the second device to the first device; and,
wherein said first device is configured to verify an environment based on a priori knowledge of the second device.
