Abstract

A method for storing the life data of complicated products, primarily different types of automotive product, particularly cars, by the contactless transmission of information between a transmitter/receiver unit and a transponder. The transmitter/receiver unit includes one or more oscillators, transmitter and receiver antennas, a modulator and a detection circuit, and the transponder includes a transmitter/receiver antenna, a modulator and a detection circuit. The transponder is intended to accompany the product during its manufacture and to also accompany the finished product. The transponder (24; 29) is caused to communicate in a contactless fashion with both the transmitter/receiver unit (27; 28; 20) and a transmitter device which is located in a product and incorporated in a data network in the vehicle, by making the data network in the product identical to or compatible with the data network used for the contactless transmission between the transmitter/receiver unit (27; 28; 20) and the transponder (24; 29) in the manufacture of the product.

Claims

1. A method for storing product-related data for retrieval during manufacture of a product and for retrieval during use of the product after manufacture, said method comprising:

a. providing a transponder including a non-volatile memory for retaining product-related data including both product production data and product operation data, antenna means for receiving and for transmitting data signals, a receiver for receiving a modulated signal from a data transmitter, a demodulator coupled with the receiver for demodulating the modulated signal and coupled with the memory for conveying the modulated signal to the memory;

b. attaching the transponder to the product during manufacture of the product for retention by the product during manufacture and during use of the product subsequent to manufacture;

c. transmitting product production data between the transponder and a product manufacturing data transmitter/receiver while the product is being manufacture, for retention in the transponder memory of product manufacturing data for subsequent retrieval;

d. providing on the product a data network including an apparatus for receiving and storing product operating data, wherein the product operating data receiving and storing apparatus is adapted for communication with the transponder carried by the product;

e. retaining the transponder on the product after manufacturing operations on the product have been completed and while the product is in its intended use;

f. recording product operating data in the transponder memory as the product is being used for its intended purpose; and

g. communicating product operating data and product production data between the transponder and a product operating data receiving apparatus after the product has been manufactured and has been in use.

2. A method in accordance with claim 1 wherein the communication to and from the transponder is effected by inductive coupling.

3. A method in accordance with claim 1 wherein the communication to and from the transponder is effected by capacitive coupling.

4. A method in accordance with claim 1 including the step of mounting a transmitter on the product, the product-mounted transmitter adapted to communicate with the transponder and with a transmitter/receiver external to the product, and wherein the product-mounted transmitter communicates with the transponder and with the transmitter/receiver external to the product by inductive coupling.

5. A method in accordance with claim 1 including the step of mounting a transmitter on the product, the product-mounted transmitter adapted to communicate with the transponder and with a transmitter/receiver external to the product, and wherein the product-mounted transmitter communicates with the transponder and with the transmitter/receiver external to the product by capacitive coupling.

6. A method in accordance with claim 1 including the step of providing on the product an auxiliary transmitter/receiver for communication with the transponder, the auxiliary transmitter/receiver coupled inductively with the transponder for communication therewith and adapted for microwave communication of product production data with a transmitter/receiver that is external to the product.

7. A method in accordance with claim 1 including the step of providing on the product an auxiliary transmitter/receiver for communication with the transponder, the auxiliary transmitter/receiver coupled capacitively with the transponder for communication therewith and adapted for microwave communication of product production data with a transmitter/receiver that is external to the product.

8. A method in accordance with claim 1 including the step of providing on the product an auxiliary transmitter/receiver for communication with the transponder, the auxiliary transmitter/receiver coupled inductively with the transponder for communication therewith and adapted for communication by light signals of product production data with a transmitter/receiver that is external to the product.

9. A method in accordance with claim 1 including the step of providing on the product an auxiliary transmitter/receiver for communication with the transponder, the auxiliary transmitter/receiver coupled capacitively with the transponder for communication therewith and adapted for communication by light signals of product production data with a transmitter/receiver that is external to the product.

10. A method in accordance with claim 6 wherein the auxiliary transmitter/receiver includes a memory to provide additional data storage capacity.

11. A method in accordance with claim 7 wherein the auxiliary transmitter/receiver includes a memory to provide additional data storage capacity.

12. A method in accordance with claim 8 wherein the auxiliary transmitter/receiver includes a memory to provide additional data storage capacity.

13. A method in accordance with claim 9 wherein the auxiliary transmitter/receiver includes a memory to provide additional data storage capacity.
