Abstract

A system of a machine includes a network of a plurality of identification devices distributed throughout the machine. Each of the identification devices are embedded in a component of the machine and operable to communicate through a plurality of electromagnetic signals. Each identification device includes a unique code characteristic of the component and the identification device is readable by one or more readers to interrogate the unique code characteristic. Shielding surrounds at least one of the identification devices to contain the electromagnetic signals proximate to the component and a communication path is integrally formed in the component of the machine to route a portion of the electromagnetic signals through the component. A remote processing unit is operable to communicate with the network of the identification devices through the electromagnetic signals.

First claim

The invention claimed is:

1. A component assembly of a machine, comprising:
a component;
an identification device embedded in the component, the identification device including a unique code characteristic of the component communicable through an electromagnetic signal, the identification device readable by one or more readers to interrogate the unique code characteristic;
a communication path integrally formed in the component and extending from the identification device to route a portion of the electromagnetic signal through the component; and
a wave guide structure disposed in the communication path;
wherein the component includes a component substrate, the identification device disposed at a substrate pocket formed in the component substrate with an electromagnetic reflector.

2. The component assembly of claim 1 , wherein the identification device is a radio frequency sensor.

3. The component assembly of claim 1 , further comprising a coating layer applied to the component substrate to enclose the identification device in the substrate pocket.

4. The component assembly of claim 1 , further comprising one or more physically unclonable features applied to the component.

5. The component assembly of claim 4 , wherein the one or more readers are configured to read the one or more physical unclonable features.

6. The component assembly of claim 4 , wherein the one or more physically unclonable features utilize the constituent materials of the component as markers.

7. The component assembly of claim 6 , wherein the one or more readers are configured to read the markers.

8. A system of a machine, the system comprising:
a network of a plurality of identification devices distributed throughout the machine, each of the identification devices embedded in a component of the machine and operable to communicate through a plurality of electromagnetic signals, each identification device including a unique code characteristic of the component, the identification device readable by one or more readers to interrogate the unique code characteristic;
shielding surrounding at least one of the identification devices to contain the electromagnetic signals proximate to the component;
a communication path integrally formed in the component of the machine and extending from the identification device to route a portion of the electromagnetic signals through the component;
a remote processing unit operable to communicate with the network of the identification devices through the electromagnetic signals; and
a wave guide structure disposed in the communication path;
wherein the component includes a component substrate, the identification device disposed at a substrate pocket formed in the component substrate with an electromagnetic reflector.

9. The system of claim 8 , wherein the identification device is a radio frequency sensor.

10. The system of claim 8 , further comprising a coating layer applied to the component substrate to enclose the identification device in the substrate pocket.

11. The system of claim 8 , further comprising one or more physically unclonable features applied to the component, wherein the one or more physically unclonable features utilize the constituent materials of the component as markers.

12. A system for a gas turbine engine, the system comprising:
a network of a plurality of identification devices distributed throughout the gas turbine engine, each of the identification devices embedded in a gas turbine engine component and operable to communicate through a plurality of electromagnetic signals, each identification device including a unique code characteristic of the gas turbine engine component, the identification device readable by one or more readers to interrogate the unique code characteristic;
shielding surrounding at least one of the identification devices to contain the electromagnetic signals proximate to the gas turbine engine component;
a communication path integrally formed in the gas turbine engine component and extending from the identification device to route a portion of the electromagnetic signals through the gas turbine engine component;
a remote processing unit operable to communicate with the network of the identification devices through the electromagnetic signals; and
a wave guide structure disposed in the communication path;
wherein the gas turbine engine component includes a component substrate, the identification device disposed at a substrate pocket formed in the component substrate with an electromagnetic reflector.

13. The system as recited in claim 12 , wherein the gas turbine engine component is part of at least one of a fan section, a compressor section, a combustor section and a turbine section of the gas turbine engine.

14. The system of claim 12 , wherein the identification device is a radio frequency sensor.

15. The system of claim 12 , further comprising a coating layer applied to the component substrate to enclose the identification device in the substrate pocket.

16. The system of claim 12 , further comprising one or more physically unclonable features applied to the component.

17. The system of claim 16 , wherein the one or more physically unclonable features utilize the constituent materials of the component as markers.
