Abstract

A tire pressure monitoring tool transmits a triggering signal to a tire sensor; receives a reporting signal from the tire sensor; extracts data from the reporting signal; stores the extracted data; and transmits the stored data to an external device. The transmitted stored data is in a predetermined order, and in a text format.

Claims

1. A portable tire pressure monitoring tool comprising:

a) an antenna for transmitting a triggering signal for multiple tire sensors, and for receiving a reporting signal from the multiple tire sensors;

b) a processor;

c) a memory with stored programming, for;

i) transmitting the triggering signal,

ii) receiving the reporting signal,

iii) extracting data from the reporting signal, and

iv) storing the extracted data; and

d) a communication device for transmitting the stored data to an external device wherein;

the stored programming is configured to extract and store data from at least two distinct reporting signals received from two distinct tire sensors, respectively, and

the stored programming is configured for grouping the stored data in a format that identifies the stored data as associated with a single vehicle.

2. The tool of claim 1, wherein the memory also has stored programming for:

v) formatting the stored data for transmission.

3. The tool of claim 1, wherein the stored programming is configured to extract and store data from at least four distinct reporting signals received from four distinct tire sensors, respectively.

4. The tool of claim 1, wherein the communication device comprises an electrical contact type communication port.

5. The tool of claim 1, wherein the electrical contact type communication port is a universal serial bus.

6. The tool of claim 1, wherein the communication device is a wireless communication device.

7. The tool of claim 1, wherein the format comprises a text format with data organized as an array;

and wherein the text format is adapted to be displayed to a user.

8. The tool of claim 7, wherein the text format is adapted to be displayed to a user via a computer monitor.

9. The tool of claim 7, wherein the text format is adapted to be displayed to a user via a printer.

10. A method for using a tire pressure monitoring tool to trigger, receive, extract, store, and transmit tire sensor data, comprising:

a) transmitting a triggering signal to a tire sensor;

b) receiving a reporting signal from the tire sensor;

c) extracting data from the reporting signal;

d) storing the extracted data; and

e) transmitting the stored data to an external device wherein;

steps a) through d) are repeated once for each tire sensor on a vehicle, and wherein step e) transmits the stored data from each tire sensor on a vehicle in a grouped format that identifies the data as associated with a single vehicle.

11. The method of claim 10, further comprising formatting the stored data for transmission, before transmitting the stored data.

12. The method of claim 10, wherein receiving step b) further comprises sending a visual or audio signal to a tool operator to indicate that a reporting signal has been received.

13. The method of claim 10, wherein receiving step b) further comprises receiving multiple reporting signals in response to a single triggering signal.

14. The method of claim 10, wherein the extracted data comprises a tire sensor identification, a tire pressure, and a tire temperature.

15. The method of claim 14, wherein the extracted data further comprises a tire sensor battery status.

16. The method of claim 14, wherein the extracted data further comprises any error codes present in the reporting signal.

17. The method of claim 10, wherein the tire sensors on a vehicle are triggered in a predetermined order.

18. The method of claim 17, wherein the predetermined order is:

front left tire sensor, front right tire sensor, rear right tire sensor, and rear left tire sensor.

19. The method of claim 17, wherein the predetermined order is:

front left tire sensor, front right tire sensor, rear right tire sensor, spare tire sensor, and rear left tire sensor.

20. The method of claim 10, wherein the grouped format comprises a text format adapted to be displayed.

21. The method of claim 20, wherein the text format is American Standard Code for Information Interchange.

22. The method of claim 10, further comprising:

f) storing the transmitted data in a computer.

23. The method of claim 10, further comprising:

f) displaying the transmitted data on a computer monitor.

24. The method of claim 10, further comprising:

f) printing the transmitted data on a printer.
