Cable with embedded information carrier unit
First Claim
1. Cable, comprising:
- an inner cable body, in which electrical conductor strands run in a longitudinal direction of the cable,a cable sheath, enclosing the inner cable body and lying between an outer surface of the cable and the inner cable body, andat least one information carrier unit, disposed within the outer surface of the cable, the information carrier unit comprising a substantially flat base made of a flexible material and a conductor acting as a coreless antenna unit disposed on the base, which antenna unit can be coupled with a read/write device by parasitic electromagnetic fields between the antenna unit and at least two of the electrical conductor strands of the inner cable body.

Abstract
In order to improve a cable, comprising an inner cable body, in which electrical conductor strands run in the longitudinal direction of the cable, a cable sheath, enclosing the inner cable body and lying between an outer surface of the cable and the inner cable body, and at least one information carrier unit, disposed within the outer surface of the cable, to increase the range of communication between the information carrier unit and the read/write device, it is proposed to provide the information carrier unit having an antenna unit, which can be coupled with a read/write device by parasitic electromagnetic fields between the antenna unit and at least two of the electrical conductor strands of the inner cable body.

11. Cable, comprising:
-
an inner cable body, in which electrical conductor strands run in a longitudinal direction of the cable, a cable sheath, enclosing the inner cable body and lying between an outer surface of the cable and the inner cable body, a multiplicity of information carrier units, disposed within the outer surface of the cable, said information carrier units being disposed in the longitudinal direction of the cable at a distance from one another, and an antenna unit of one of the information carrier units adapted to be coupled with the antenna unit of another of the information carrier units by electromagnetic field coupling; the antenna units of the information carrier units being adapted to be coupled by way of parasitic electromagnetic fields over the at least two electrical conductor strands; by the parasitic electromagnetic fields between one of the antenna units of the information carrier units and the at least two conductor strands, an antenna range of the antenna unit of the information carrier that is increased by a factor of more than two in comparison with an antenna range of an antenna unit that is uninfluenced by the parasitic electromagnetic fields, being obtained in the longitudinal direction of the cable; and the information carrier units being disposed at defined regular intervals in relation to one another in such a way that the distances between the information carrier units correspond to at least 2.5 times an effective antenna range of the information carrier units in a direction of the respectively nearest information carrier units. - View Dependent Claims (12, 13, 14, 15, 16)

17. Method of communication between a read/write device and an information carrier unit which is disposed in a cable, the information carrier unit being disposed between an outer surface of the cable and an inner cable body of the cable, the inner cable body having at least two electrical conductor strands running in the longitudinal direction of the cable, the method comprising:
-
exciting of the two electrical conductor strands by means of the read/write device, coupling the two electrical conductor strands with a coreless antenna unit disposed on a flat base of the information carrier unit by means of parasitic electromagnetic fields, and transferring an information signal between the information carrier and the read write device via the electromagnetic fields.
