Abstract
Abstract The present invention relates to a sealing device provided for being applied onto an object to be sealed, said device comprising an electronic component with a memory, which component is connected to a first loop comprising a communication means, said communication means being provided for communicating with reading means, characterised in that a second loop, connected to the electronic component, is provided for letting energy circulating through it and to be broken upon breaking said sealing device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
A sealing device provided for being applied onto an
object to be sealed, said device comprising an electronic component with
a memory, which component is connected to a first loop comprising a
communication means, said communication means being provided for
communicating with reading means, characterised in that a second loop,
connected to the electronic component, is provided for letting energy
circulating through it and to be broken upon breaking said sealing
device.
Claim 2
Dependent Claim
19 words
A device according to claim 1, characterised in that it is
provided for being powered by said reading means.
Claim 3
Dependent Claim
22 words
A device according to claim 1 or 2, characterised in that
said second loop is connected in parallel with the first loop.
Claim 4
Independent Claim
23 words
A device according to any one of the claims 1 to 3,
characterised in that a capacitance is provided in the second loop.
Claim 5
Independent Claim
23 words
A device according to any one of the claims 1 to 3,
characterised in that an inductance is provided in the second loop.
Claim 6
Dependent Claim
40 words
A device according to claim 1 or 2, characterised in that it
comprises means provided for generating a first codeword upon
establishing that the second loop is intact and a second codeword upon
establishing that the second loop is broken.
Claim 7
Dependent Claim
34 words
A device according to claim 6, characterised in that said
memory is connected to counter means provided for memorising how
many times the object, onto which the device has been applied, has
been sealed.
Claim 8
Independent Claim
28 words
A device according to any one of the claims 1 to 7,
characterised in that a first identification codeword for identifying said
device is stored in said memory.
Claim 9
Independent Claim
45 words
A device according to any one of the claims 1 to 8,
characterised in that said memory is provided for being stored with a second
identification codeword by means of writing means, which second
identification codeword identifies the content of the object to be sealed.
Claim 10
Dependent Claim
18 words
A device according to claim 1 or 2, characterised in that
said second loop is an optical loop.
