Abstract
Abstract An electronic seal including an electronic tag, an electrically resistive element in electrical communication with and attached to the tag, the resistive element being bondable to an object so as to define an electrical resistance, wherein a change in bonding of the element to the object causes a change in the electrical resistance, the change in electrical resistance being communicated to the tag.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
An electronic seal comprising: an electronic tag; an electrically resistive element in electrical communication with and attached to said tag, wherein tampering with the electrically resistive element causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element comprises a multiplicity of resistive wires, wherein only a random number of said wires are electrically connected to internal connection points in said tag such that said resistive element has a statistically random electrical resistance.
Claim 2
Dependent Claim
83 words
An electronic seal comprising: an electronic tag; an electrically resistive element in electrical communication with and attached to said tag, wherein tampering with the electrically resistive element causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element comprises a multiplicity of resistive wires, wherein only a random number of said wires are electrically connected to internal connection points in said tag such that said resistive element has a statistically random electrical resistance.
Claim 3
Dependent Claim
27 words
A seal according to claim 1 wherein said tag transmits said change in electrical resistance to a transceiver, said transceiver communicating said change to a detection system.
Claim 4
Dependent Claim
18 words
A seal according to claim 2 wherein said tag transmits said change to said transceiver by RF transmission.
Claim 5
Dependent Claim
44 words
A seal according to claim 1 wherein said resistive element is bonded to said tag with an electrically conductive adhesive having an adhesive strength, said element being bonded to said object with an adhesive strength greater than the adhesive strength of said conductive adhesive.
Claim 6
Dependent Claim
35 words
A seal according to claim 1 wherein said tag operates in a sleeping mode and said change in electrical resistance is communicated to said tag only when said tag is activated with a wake-up signal.
Claim 7
Dependent Claim
16 words
A seal according to claim 5 wherein a transceiver communicates said wake-up signal to said tag.
Claim 8
Dependent Claim
26 words
A seal according to claim 1 and wherein said tag comprises a timer and memory for monitoring time and duration of said change in electrical resistance.
Claim 9
Dependent Claim
20 words
A seal according to claim 7 and wherein said memory stores at least one of identification data and asset data.
Claim 10
Dependent Claim
103 words
An electronic seal comprising: an electronic tag; an electrically resistive element in electrical communication with and attached to said tag, said resistive element being adhesively bondable to an object so as to define an electrical resistance, wherein a change in adhesive bonding of said element to said object causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element is bonded to said tag with an electrically conductive adhesive having an adhesive strength, said element being bonded to said object with an adhesive strength greater than the adhesive strength of said conductive adhesive.
Claim 11
Dependent Claim
103 words
An electronic seal comprising: an electronic tag; an electrically resistive element in electrical communication with and attached to said tag, said resistive element being adhesively bondable to an object so as to define an electrical resistance, wherein a change in adhesive bonding of said element to said object causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element is bonded to said tag with an electrically conductive adhesive having an adhesive strength, said element being bonded to said object with an adhesive strength greater than the adhesive strength of said conductive adhesive.
