Abstract

A number of frames in a burst is adjusted such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer. The number of frames in the burst is adjusted such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer. The number of frames in the burst maintains a configuration compliant with government regulations regarding one or more of a burst length and a power emission.

First claim

What is claimed is:

1. A method of forming a burst of frames for transmission in a tire pressure monitoring system, the method comprising: adjusting a number of frames in a burst such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer; adjusting the number of frames in the burst such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer; wherein the number of frames in the burst maintains a configuration compliant with government regulations regarding one or more of a burst length and a power emission, wherein the burst configuration cannot be changed by a user without a control program being entirely re-programmed.

2. The method of claim 1 , wherein the burst comprises an on-the-air signal and the on-the-air signal does not exceed one second.

3. The method of claim 1 , wherein the burst is transmitted at a particular frequency and the average power does exceed 67.5 db uV/m at three meters.

4. The method of claim 1 , wherein the burst has a configuration compliant with an industry requirement.

5. A method of forming a burst of frames for transmission in a tire pressure monitoring system, the method comprising: adjusting a number of frames in a burst such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer; adjusting the number of frames in the burst such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer; wherein the number of frames in the burst maintains a configuration compliant with government regulations regarding one or more of a burst length and a power emission, wherein the burst has the configuration compliant with an industry requirement, and wherein the industry requirement relates to the amount of time required to complete a localization process.

6. An apparatus for transmitting tire pressure signals, the apparatus comprising: a transmission buffer configured to store tire pressure monitoring information; a transmitter configured to transmit a signal including the tire pressure monitoring information, the signal comprising: a burst with an adjustable number of frames such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer; such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer; wherein the burst maintains a configuration compliant with government regulations regarding a one or more of a burst length and a power emission, wherein the burst is transmitted at a particular frequency and the average power does exceed 67.5 db uV/m at three meters.

7. The apparatus of claim 6 , wherein the burst comprises an on-the-air signal and the on-the-air signal does not exceed one second.

8. An apparatus for transmitting tire pressure signals, the apparatus comprising: a transmission buffer configured to store tire pressure monitoring information; a transmitter configured to transmit a signal including the tire pressure monitoring information, the signal comprising: a burst with an adjustable number of frames such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer; such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer; wherein the burst maintains a configuration compliant with government regulations regarding a one or more of a burst length and a power emission, wherein the burst configuration cannot be changed by a user without a control program being entirely re-programmed.

9. An apparatus for transmitting tire pressure signals, the apparatus comprising: a transmission buffer configured to store tire pressure monitoring information; a transmitter configured to transmit a signal including the tire pressure monitoring information, the signal comprising: a burst with an adjustable number of frames such that a first optimal number of first frames from a first manufacturer are included in the burst, the first optimal number of frames chosen to enable the detection of the burst by first receivers that are tuned to receive the first frames from the first manufacturer; such that a second optimal number of second frames from a second manufacturer are included in the burst, the second optimal number of frames chosen to enable detection of the burst by second receivers that are tuned to receive the second frames from the second manufacturer; wherein the burst maintains a configuration compliant with government regulations regarding a one or more of a burst length and a power emission, wherein the burst has a configuration compliant with an industry requirement, wherein the industry requirement relates to the amount of time required to complete a localization process.

10. A method of forming a burst of frames for transmission in a tire pressure monitoring system, the method comprising: disposing first frames of a first manufacturer at a first position in a burst, and disposing second frames of a second manufacturer at a second position in the burst, the first position being sequentially earlier in time than the second position; wherein the length of the first frames is shorter than the length of the second frames; wherein the burst pattern cannot be changed by a user without a control program being entirely re-programmed.

11. The method of claim 10 , wherein the burst comprises an on-the-air signal and the on-the-air signal does not exceed one second.

12. The method of claim 10 , wherein the burst is transmitted at a particular frequency and the average power does exceed 67.5 db uV/m at three meters.

13. The method of claim 10 , wherein the burst has a configuration compliant with an industry requirement.

14. The method of claim 13 , wherein the industry requirement relates to the amount of time required to complete a localization process.

15. An apparatus for transmitting tire pressure signals, the apparatus comprising: a transmission buffer configured to store tire pressure monitoring information; a transmitter configured to transmit a signal including the tire pressure monitoring information when activated externally by a trigger, the signal comprising: a burst with an adjustable number of frames such that a first optimal number of first frames from a first manufactu
