Abstract

A method of performing a configuration procedure for first and second tire pressure monitoring devices. The method includes loading the first tire pressure monitoring device with first configuration data, and subsequently transmitting, from the first tire pressure monitoring device, a first configuration data signal which encodes the first configuration data. The method includes subsequently loading the second tire pressure monitoring device with second configuration data, and subsequently ending the configuration procedure without transmitting a second configuration data signal which encodes the second configuration data.

First claim

The invention claimed is:

1. A method of performing a configuration procedure for first and second tire pressure monitoring devices, the method comprising:
loading the first tire pressure monitoring device with first configuration data,
subsequently transmitting, from the first tire pressure monitoring device, a first configuration data signal which encodes the first configuration data,
subsequently loading the second tire pressure monitoring device with second configuration data, and
subsequently ending the configuration procedure without transmitting a second configuration data signal which encodes the second configuration data.

2. The method according to claim 1 , wherein the first configuration data signal is configured to be received and understood by a human.

3. The method according to claim 1 , wherein the first configuration data signal comprises a signal indicative of any of a reference pressure for a tire and an installed location of the first tire pressure monitoring device.

4. The method according to claim 1 , wherein the first configuration data signal comprises a visual signal, and
the method further comprises transmitting the visual signal using a visual indicator of the first tire pressure monitoring device.

5. The method according to claim 4 , wherein the visual indicator comprises a light source, and
the method further comprises selectively illuminating the light source to perform the step of subsequently transmitting the first configuration data signal.

6. The method according to claim 5 , wherein the first configuration data signal comprises a number, and the selective illumination of the light source comprises encoding the number into an illumination sequence representing individual digits of the number.

7. The method according to claim 1 , wherein the method further comprises verifying, by a human, that the configuration data encoded by the first configuration data signal matches expected configuration data, and verification by a human that the first configuration data matches expected configuration data takes place using an untrusted device.

8. The method according to claim 1 , wherein the first and second tire pressure monitoring devices correspond to a wheel group of an aircraft.

9. The method according to claim 1 , wherein the first and second tire pressure monitoring devices are part of a set of tire pressure monitoring devices, and the method further comprises:
loading each of a further set of tire pressure monitoring devices with respective configuration data; and
transmitting, from a subset of fewer than all of the further set of tire pressure monitoring devices, a configuration data signal which encodes the respective configuration data.

10. The method according to claim 9 , wherein the set of tire pressure monitoring devices correspond to a first wheel group of an aircraft, and the further set of tire pressure monitoring devices correspond to a second wheel group of the aircraft different to the first wheel group.

11. The method according to claim 9 , where the subset of the further set of tire pressure monitoring devices comprises a single tire pressure monitoring device of the further set of tire pressure monitoring devices.

12. The method according to claim 1 , wherein loading each of the first and second tire pressure monitoring devices with respective first and second configuration data comprises utilising an untrusted device.

13. The method according to claim 1 , wherein the first and second tire monitoring devices form part of a set of tire monitoring devices, and the transmitting the first configuration data signal which encodes the first configuration data takes place in a configuration data check procedure, and the method further comprises:
transmitting, from a further subset of the set of tire pressure monitoring devices, further respective configuration data to at least one of the first and second tire pressure monitoring devices in a tire pressure check procedure different to the configuration data check procedure; and
determining, at the at least one of the first and second tire pressure monitoring devices, whether the further configuration data matches the respective first or second configuration data.

14. The method according to claim 13 , wherein the method comprises, when the further configuration data differs from the respective first or second configuration data, transmitting, from any of the set of tire pressure monitoring devices, an error signal.

15. A system comprising first and second tire pressure monitoring devices configured to operate according to the method of claim 1 .

16. A tire pressure monitoring device configured to operate as part of the system according to claim 15 .

17. An aircraft comprising at least one of a system according to claim 1 .
