Abstract

A land vehicle mileage measuring system (1) comprises a processor (2), clock (5), movement sensor (6), memory (10), battery (9) and anti-tamper sensor (8) all enclosed in a housing (7). In operation the processor (2) processes mileage data and signals from the clock (5) and movement sensor (6), encrypts the resulting data and stores it in the memory (10).

Claims

AMENDED CLAIMS[received by the International Bureau on l sl November 1999 (01.1 1 99), original claim 1 amended, original claim 2 deleted, original claims 3-13 renumbered as amended claims 2-12 (2 pages)]

1. A land vehicle mileage measuring system comprising mileage data supply means for supplying mileage data signals to a processor, a clock for supplying clock signals to the processor, a movement sensor for providing movement signals to the processor, an engine operation data supply means for supplying engine operation data signals to the processor, a memory and a power source to power the other elements, the processor processing the mileage data, clock, movement and engine operation data signals and storing data derived therefrom in the memory.

2. A system as claimed in Claim 1, and further comprising a sealed housing enclosing the processor, the memory, the clock, the movement sensor and the power source.

3. A system as claimed m Claim 2, and further comprising a tamper sensor for supplying a tamper indicating signal to the processor if the housing is opened.

4. A system as claimed in any preceding claim, in which at least some of the data stored m the memory is encrypted.

5. A system as claimed in any preceding claim, and further comprising a data output means for outputtmg data stored in the memory from the system.

6. A system as claimed in Claim 5, when dependent on Claim 4, in which the encrypted data stored in the memory can only be output from the system by the data output means in encrypted form.

7. A system as claimed in any preceding claim, and further comprising a data input means for storing data from outside the system in the memory.

8. A system as claimed in any preceding claim, in which the memory stores data uniquely identifying the system.

9. A system as claimed in any preceding claim, in which the memory can store data identifying the vehicle to which the system is attached.

10. A system as claimed in Claim 5 in which the transfer of data from the memory by the data output means is password controlled.

11. A system as claimed in Claim 7 in which the transfer of data to the memory by the data input means is password controlled.

12. A land vehicle mileage measuring system substantially as shown in or as described with reference to the accompanying figure.
