Abstract

A self-powered electronic system, which is embeddable in a tire for a ground vehicle or a tire for an aerial vehicle, includes an electronic device, a transmitter, a storage medium, and communication means. The electronic device is structured to measure or record, or measure and record, data relating to a vehicle carrying the electronic device. The data may include information on use of the vehicle. The transmitter is structured to transmit the data to a remote interrogation system. The storage medium is a passive data storage medium that is structured to be able to be remotely interrogated. The communication means is structured to enable communication between the electronic device and the storage medium.

Claims

1. A self-powered electronic system useable in a ground vehicle or an aerial vehicle, the electronic system comprising:

a first storage medium configured to store data relating to a vehicle used with the electronic system, the data including data regarding use of the vehicle;

a transmitter, which transmits the data to a remote system;

a second storage medium, which is a passive storage medium and which is able to be remotely interrogated; and

communication means, which enables communication between the first storage medium and the second storage medium,

wherein the communication means is structured to transmit the data from the first storage medium to the second storage medium for storage in the second storage medium, and

wherein the electronic system is structured to be embeddable in a layer of a tire for the vehicle.

2. The system according to claim 1, wherein the second storage medium is structured to be remotely powered by a remote interrogation system.

3. The system according to claim 1, wherein the second storage medium is physically separate from the first storage medium.

4. The system according to claim 1, wherein the second storage medium is an RFID device.

5. The system according to claim 1, wherein the communication means is one of:

a wired connection, an inductive connection, a radio frequency connection, and an optical connection.

6. The system according to claim 1, wherein the first storage medium includes a medium structured for temporary storage.

7. The system according to claim 1, wherein the transmitter includes a radio-frequency wireless link.

8. The system according to claim 1, wherein the electronic system is embedded in an aircraft tire.

9. The system according to claim 1, wherein the data transmitted from the first storage medium to the second storage medium includes a most recently obtained vehicle data.

10. The system according to claim 1, wherein the data transmitted from the first storage medium to the second storage medium includes a most recently obtained tire data.

11. The system according to claim 1, wherein the data transmitted from the first storage medium to the second storage medium includes an incremental value of a counter.

12. The system according to claim 1, wherein the communication means uses a clock signal to time regular transmission of data from the first storage medium to the second storage medium, and

wherein in conjunction with the transmission, chronological information regarding a last back-up is updated.

13. A self-powered electronic system embeddable in a tire for a ground vehicle or a tire for an aerial vehicle, the self-powered electronic system comprising:

a first storage medium configured to store data relating to a vehicle carrying the electronic device, the data including data regarding use of the vehicle;

a transmitter, which transmits the data to a remote system;

a second storage medium, which is a passive storage medium and which is able to be remotely interrogated; and

communication means, which enables communication between the first storage medium and the second storage medium and which includes a serial wired communication interface that includes a bidirectional transmission channel structured to transmit the data from the first storage medium to the second storage medium for storage in the second storage medium,

wherein the communication means uses a clock signal to time regular transmission of data from the first storage medium to the second storage medium, and

wherein in conjunction with the transmission, chronological information regarding a last back-up is updated.

14. The system according to claim 13, wherein the serial wired communication interface includes an SPI interface or an I2C interface.

15. A system according to claim 13, wherein the system is embedded in a layer of the tire.
