Abstract
Abstract System for the transfer of data relating to vehicles (4, 4'), comprising vehicle units (1, 1') disposed in vehicles (4, 4'), a central unit (3), and at least one intermediate unit (2), which intermediate unit is equipped for at least the temporary storage of data, the system being equipped for the transfer of data between the vehicle units (1, 1') and the intermediate unit (2), on the one hand, and between the central unit (3) and the intermediate unit (2), on the other hand, the system further being equipped for the remote transfer of data by means of infrared light between the vehicle units (1, 1') and the intermediate unit (2). The vehicle unit (1) of a vehicle (4) is advantageously situated inside the vehicle (4) behind a window of said vehicle, which window is preferably the windscreen (5). The intermediate unit is preferably equipped for the storage of data from several vehicles (4, 4').

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
148 words
System for the transfer of data relating to vehicles (4,4'), comprising vehicle units (1, 1') disposed in vehicles (4,4'), a central unit (3), and at least one intermediate unit (2), which intermediate unit (2) is equipped for at least temporarily storing data, the system being equipped for the transfer of data between the vehicle units (1,1') and the intermediate unit (2), on the one hand, and between the central unit (3) and the intermediate unit (2), on the other hand, and the system further being equipped for the transfer of data by means of infrared light between the vehicle units (1,1') and the intermediate unit (2), characterized in that the system is equipped for the remote bidirectional transfer of data between the vehicle units (1,1') and the at least one intermediate unit (2), the intermediate unit (2) being equipped for the storage of data from several vehicles (4,4').
Claim 2
Dependent Claim
29 words
System according to claim 1, the system being equipped for the remote bidirectional transfer of data between the central unit (3) and the at least one intermediate unit (2).
Claim 3
Dependent Claim
32 words
System according to claim 1 or 2, in which a vehicle unit (1) is situated inside a vehicle (4) behind a window of said vehicle, which window is preferably the windscreen (5).
Claim 4
Dependent Claim
23 words
System according to any of the preceding claims, in which the vehicle units (1,1') are arranged to prevent the manual input of data.
Claim 5
Dependent Claim
42 words
System according to any of the preceding claims, in which the transfer of data between a vehicle unit (1) and an intermediate unit (2) is possible only if said transfer includes a password which is unique for the particular vehicle unit (1).
Claim 6
Dependent Claim
42 words
System according to claim 5, in which the vehicle units (1, 1') are arranged for replacing the password by a new password, the vehicle data stored in the vehicle unit being erased if the new password is transferred without the existing password.
Claim 7
Dependent Claim
45 words
System according to any of the preceding claims, equipped for data transfer in data blocks and for recording the number of data blocks transmitted, in order to ensure that after an interruption in the data transfer retransmission of data blocks already transmitted does not occur.
Claim 8
Dependent Claim
53 words
System according to any of the preceding claims, in which the vehicle units (1, 1') are equipped for the storage of data relating to the opening of the doors and tailboard, the running of the engine, the mileage, the speed and the level in the fuel tank of the respective vehicle (4; 4').
Claim 9
Dependent Claim
63 words
System according to any of the preceding claims, in which the vehicle units (1, 1') are equipped for the storage of data relating to the current geographic position of the respective vehicle (4; 4'), the central unit (3) preferably being linked to a data processing unit (6) which is capable of graphically presenting, inter alia, the journeys covered by the vehicles (4, 4').
Claim 10
Dependent Claim
81 words
Intermediate unit (2) for use in a system according to any of the preceding claims, comprising a control unit (21), a memory (22) for the storage of vehicle data, a user interface (23) comprising a keyboard for entering instructions, and means (24, 25) for the remote transfer of vehicle information, said means (24, 25) comprising a transmitter for the transfer of the vehicle data to a vehicle unit (1) and/or to a central unit (3) and a receiver for receiving data.
Claim 11
Dependent Claim
36 words
Vehicle unit (1) for use in a system according to any of Claims 1 through 9, comprising a programmable processor (12), a memory (11), and communications means (13) comprising an infrared transmitter and an infrared receiver.
Claim 12
Dependent Claim
70 words
Transmitting and receiving circuit (100) for use in a system according to any of claims 1 through 9, comprising a transmitter (101), a receiver (102), a time-delay circuit (105, 106, 107, 108) for delaying the receiving signal, and a combination circuit (110) for combining the transmitting signal and the receiving signal in such a way that the receiving signal is suppressed during the transmission and for a short time thereafter.
