Abstract

A magnetic induction data transmission network comprising a master hub, at least one sensor node communicatively coupled to the master hub and a magnetic induction coil preferably adapted to be worn about a body part of a subject such as an individual'"'"'s waist or neck. In at least one embodiment of the invention, the magnetic induction coil preferably includes a connector which serves as an intermediary between the coil and the hub to allow data communication.

Claims

1. A magnetic induction data transmission network, comprising:

a master hub;

at least one sensor node communicatively coupled to said master hub to allow said master hub and said at least one sensor node to receive and transmit data; and

a magnetic induction coil adapted to be worn about a body part of a subject, said magnetic induction coil being connected to said master hub to allow said data reception and transmission.

2. The data transmission network of claim 1, wherein said magnetic induction coil has a diameter greater than about eight inches.

3. The data transmission network of claim 2, wherein said magnetic induction coil has a diameter between about eight inches and about fifteen inches.

4. The data transmission network of claim 1, wherein said master hub includes a magnetic induction transceiver.

5. The data transmission network of claim 1, wherein said at least one sensor node includes a magnetic induction transceiver.

6. The data transmission network of claim 1, wherein said at least one sensor node and said magnetic induction coil are misaligned by an angle of plus or minus forty-five degrees.

7. The data transmission network of claim 1, wherein said magnetic induction coil includes at least one wire forming at least one revolution around an individual'"'"'s waist.

8. The data transmission network of claim 1 wherein said at least one sensor node includes a physiological sensor.

9. The data transmission network of claim 1, further comprising a connector residing at a transaction point of said magnetic induction coil, said connector serving as an intermediary between said coil and said hub.

10. The data transmission network of claim 9, wherein said connector includes

a plug terminal including a set of plug pins;

and

a receptacle terminal including a set of receptacle pins;

wherein each of said plug pins corresponds to a receptacle pin.

11. The data transmission network of claim 10, wherein said magnetic induction coil includes N turns where N≧

2 and the first end of the Nth turn is connected to receptacle the N−

1th receptacle pin and the second end of the Nth turn is connected to the Nth plug pin.

12. The data transmission network of claim 11 wherein the first end of the first turn is connected to said master hub and the second end of the first turn is connected to the first receptacle.

13. The data transmission network of claim 12 wherein the Nth receptacle is connected to said master hub.

14. A magnetic induction coil adapted to fit a body part of an individual comprising N coil turns where N≧

2, the N−

1 coil turn being adjacent to and parallel with the Nth coil turn, the coil being transected at a transaction point and a connector coupled to said coil turns to interconnect said coil turns.

15. The magnetic induction coil of claim 14 wherein said connector includes

a plug terminal including a set of N plug pins;

and

a receptacle terminal including a set of N receptacle pins.

16. The magnetic induction coil of claim 15, said coil comprises a spirally wound wire.

17. The magnetic induction coil of claim 15, wherein said coil comprises a loop of a single layer of wires.

18. The magnetic induction coil of claim 15 wherein each coil turn includes first and second ends and the first end of the Nth turn is connected to the N−

1th receptacle pin and the second end of the Nth turn is connected to the Nth plug pin.

19. The magnetic induction coil of claim 18 wherein the first end of the first coil turn is adapted to connect to a hub and the second end of the first turn is connected to a first receptacle pin.

20. The magnetic induction coil of claim 19 wherein the Nth receptacle is adapted to be connected to a hub.
