Abstract

An arrangement of devices which may be worn on the body of a person comprising a first device for transmitting signals to at least one second device via electromagnetic fields or waves, with the first device comprising a transmitter for transmitting such signals and an antenna connected to this transmitter, having a linear or chain-like, but not necessarily straight, arrangement of materials starting from the antenna, which affect the path of the electromagnetic waves or fields transmitted or produced by the antenna, such that at the location of at least one second device a higher receiving field strength of the signals transmitted by the transmitter prevails than without this arrangement of materials.

Claims

1-16. -16. (canceled)

17. An arrangement of devices to be worn on a body of a person, comprising:

a first device comprising;

a transmitter that transmits a signal, and

an antenna connected to the transmitter that produces an electromagnetic field;

a second device that receives the signal via the electromagnetic field; and

an arrangement of materials starting from the antenna that affects a path of the electromagnetic field and provides a higher receiving field strength of the signal than without the arrangement of materials at a location of the second device.

18. The arrangement of devices as claimed in claim 17, wherein the arrangement of materials comprises a series of arranged elements.

19. The arrangement of devices as claimed in claim 18, wherein the elements comprise ferromagnetic material.

20. The arrangement of devices as claimed in claim 18, wherein the elements are cylindrical and enclosed by a woven fabric and bonded to one another to form an arrangement of antenna elements.

21. The arrangement of devices as claimed in claim 17, wherein the arrangement of materials is a wholly flexible tube or a partially flexible tube.

22. The arrangement of devices as claimed in claim 21, wherein the tube is partially filled with a material selected from the group consisting of:

ferromagnetic powder, granular material, and non-magnetic material.

23. The arrangement of devices as claimed in claim 17, wherein the arrangement of materials comprises a metal coating.

24. The arrangement of devices as claimed in claim 17, wherein the arrangement of materials is selected from the group consisting of:

a cord, a strap, and a belt.

25. The arrangement of devices as claimed in claim 17, wherein the arrangement of materials is linear or chain-like.

26. An arrangement of materials for an arrangement of devices to be worn on a body of a person, comprising:

a series of arranged elements that;

affects a path of an electromagnetic field generated by a first device for transmitting a signal to a second device, and

provides a higher receiving field strength of the signal than without the arrangement of materials at a location of the second device.

27. The arrangement of materials as claimed in claim 26, wherein the elements comprise ferromagnetic material.

28. The arrangement of materials as claimed in claim 26, wherein the elements are cylindrical and enclosed by a woven fabric and bonded to one another to form an arrangement of antenna elements.

29. A method for providing an arrangement of devices to be worn on a body of a person, comprising

arranging a first device to the arrangement comprising an antenna for transmitting a signal;

arranging a second device to the arrangement for receiving the signal via an electromagnetic field generated by the antenna; and

arranging materials starting from the antenna for affecting a path of the electromagnetic field and providing a higher receiving field strength of the signal than without the arrangement of materials at a location of the second device.

30. The method as claimed in claim 29, wherein the arrangement of materials is arranged to balances an antenna resonant circuit of the antenna.

31. The method as claimed in claim 29, wherein the arrangement of materials is arranged to efficiently couple the arrangement of materials to the electromagnetic field.

32. The method as claimed in claim 29, wherein the arrangement of materials is arranged to closely emerge field lines of the electromagnetic field to a receiving device of the second device.

33. The method as claimed in claim 29, wherein the arrangement of materials is arranged to alignedly emerge field lines of the electromagnetic field to a receiving device of the second device.
