Identification of assets
First Claim
1. A device for identifying an asset, the device comprisinga piece of material having predetermined physical properties, the piece of material being adapted to be irreversibly attached to the asset,a stimulation and measurement unit, including a plurality of stimulation elements, attached to the piece of material, the stimulation and measurement unit being adapted to apply a predetermined stimulation using sound waves to the piece of material and receive a corresponding response wirelessly from the piece of material and to measure the corresponding response, wherein the predetermined stimulation is applied using the plurality of stimulation elements affixed at different surfaces of the piece of material,an analysis unit adapted to analyze the measured response from the piece of material, wherein the measured response corresponds to changes caused by physical properties of the piece of material in a signal transmitted by the predetermined stimulation, anda communication unit adapted to output data representative of the analysis of the measured response.

12. A method of identifying an asset to which a piece of material having predetermined physical properties is attached, the method comprising
wirelessly applying a predetermined stimulation using sound waves to the piece of material, wherein the piece of material responds to the predetermined stimulation by outputting an electrical response to the predetermined stimulation, wherein the predetermined electrical stimulation is applied using a plurality of stimulation elements affixed at different surfaces of the piece of material; -
measuring the electrical response from the piece of material corresponding to the predetermined stimulation, wherein the measuring is performed by a processor including a response transducer; analyzing, by the processor, the measured electrical response from the piece of material, wherein the measured response corresponds to changes caused by physical properties of the piece of material in a signal transmitted by the predetermined stimulation, and outputting, by the processor, data representative of the analysis of the measured response. - View Dependent Claims (13, 14)
