Abstract

An electronic device with data stored therein is integrated into a tyre. The data is stored in a memory of the electronic device. The memory includes a data storage zone with a field reserved for a serial number of the tyre, which is stored in bit form. When the data stored in the field reserved for the serial number of the tyre is read, at least a part of the read data is decoded into at least one letter so as to determine the serial number of the tyre.

Claims

1-13. -13. (canceled)

14. A method for reading data stored in a memory of an electronic device integrated into a tyre, the memory including a data storage zone with a field reserved for a serial number of the tyre, the serial number being stored in bit form, the method comprising:

reading out data stored in the data storage zone of the memory, the data being read out from the field reserved for the serial number of the tyre; and

decoding at least a part of the data read out from the data storage zone of the memory to produce at least one letter used to determine the serial number of the tyre.

15. The method according to claim 14, wherein the data storage zone with the field reserved for the serial number of the tyre is standardized.

16. The method according to claim 14, wherein

the field reserved for the serial number of the tyre includes at least one sub-field of a first type and at least one sub-field of a second type,

the at least one sub-field of the first type includes a first number of bits, corresponding to coding for a first decimal number, and

the at least one sub-field of the second type includes a second number of bits, corresponding to coding for a second decimal number.

17. The method according to claim 16, wherein data in each sub-field of the first type is decoded to produce a first decimal number, and each first decimal number is associated with a letter.

18. The method according to claim 16, wherein the data read out from the field reserved for the serial number of the tyre is decoded as a function of at least one parameter chosen from among:

a number of the sub-fields of the first and second types in the field reserved for the serial number of the tyre;

a distribution of the sub-fields of the first and second types in the field reserved for the serial number of the tyre; and

a number of the first and second numbers of bits.

19. The method according to claim 14, wherein the data storage zone includes at least one bit field reserved for at least one element chosen from among:

a protocol header;

a filter value;

a partition value;

an identifier of a tyre manufacturer; and

an item reference.

20. The method according to claim 14, wherein

the data storage zone of the memory stores standardized data, and

the memory further includes a non-standardized data storage zone.

21. A method for storing data in a memory of an electronic device integrated into a tyre, the memory including a data storage zone with a field reserved for a serial number of the tyre, the serial number being stored in bit form, the method comprising:

encoding the serial number of the tyre into bits, the serial number of the tyre including at least one letter; and

storing the encoded serial number of the tyre in the field reserved for the serial number of the tyre in the data storage zone of the memory.

22. The method according to claim 21, wherein the data storage zone with the field reserved for the serial number of the tyre is standardized.

23. The method according to claim 21, wherein

the field reserved for the serial number of the tyre includes at least one sub-field of a first type and at least one sub-field of a second type,

the at least one sub-field of the first type includes a first number of bits, corresponding to coding for a first decimal number, and

the at least one sub-field of the second type includes a second number of bits, corresponding to coding for a second decimal number.

24. The method according to claim 23, wherein each letter of the serial number of the tyre is associated with a first decimal number, and each first decimal number is encoded in bit form.

25. A non-transitory computer-readable storage medium storing a program that, when executed, causes a computer to perform at least one of:

a decoding method for reading data stored in a memory of an electronic device integrated into a tyre, the memory including a data storage zone with a field reserved for a serial number of the tyre, the serial number being stored in bit form, the decoding method comprising;

reading out data stored in the data storage zone of the memory, the data being read out from the field reserved for the serial number of the tyre, and

decoding at least a part of the data read out from the data storage zone of the memory to produce at least one letter used to determine the serial number of the tyre; and

an encoding method for storing tyre data in the memory of the electronic device integrated into the tyre, the encoding method comprising;

encoding the serial number of the tyre into bits, the serial number of the tyre including at least one letter, and

storing the encoded serial number of the tyre in the field reserved for the serial number of the tyre in the data storage zone of the memory.

26. An electronic apparatus for determining a serial number of a tyre from an electronic device integrated into the tyre, the electronic apparatus comprising:

a sensor equipped to read out data stored in a memory of the electronic device integrated into the tyre, the data being stored in bit form in a data storage zone of the memory, and the data being read out from the data storage zone from a field reserved for the serial number of the tyre; and

a processor equipped to decode at least a part of the data read out from the data storage zone of the memory to produce at least one letter used to determine the serial number of the tyre.
