Abstract

A first signal transmission is received from a transmitter external to the monitor, the first signal having a transmission characteristic. Based upon the transmission characteristic of the first signal transmission and not any data in the first transmission, a corresponding at least one protocol is determined. A data resolution based upon the transmission characteristic is determined. A second data transmission is formed according to the corresponding at least one protocol, and the sensed data is inserted into the second data transmission according to the resolution. The second data transmission is transmitted.

First claim

What is claimed is:

1. A method of transmitting data from a tire pressure monitoring system (TPMS) monitor, comprising:
receiving a first signal transmission from a transmitter external to the monitor, the first signal having a transmission characteristic;
based upon the transmission characteristic of the first signal transmission, determining a corresponding at least one protocol;
determining a data resolution based upon the transmission characteristic;
forming a second data transmission according to the corresponding at least one protocol, and inserting sensed data into the second data transmission according to the resolution; and
transmitting the second data transmission, wherein the second data transmission corresponds to a customizable burst that includes a plurality of frames, and each of the frames includes sensed tire pressure monitoring information and wherein portions of the burst are compatible with multiple types of receivers.

2. A computer usable non-transitory medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method of transmitting data from a tire pressure monitoring system (TPMS) monitor, the method comprising:
receiving a first signal transmission from a transmitter external to the monitor, the first signal having a transmission characteristic;
based upon the transmission characteristic of the first signal transmission, determining a corresponding at least one protocol;
determining a date resolution based upon the transmission characteristic;
forming a second data transmission according to the corresponding at least one protocol, and inserting sensed data into the second data transmission according to the resolution; and
transmitting the second data transmission, wherein the second data transmission corresponds to a customizable burst that includes a plurality of frames, and each of the frames includes sensed tire pressure monitoring information and wherein portions of the burst are compatible with multiple types of receivers.

3. An apparatus, comprising:
a receiver with an input, the receiver configured to receive a first signal transmission from a transmitter external to the apparatus at the input, the first signal having a transmission characteristic;
a determine template and resolution determination module coupled to the receiver, the determine template and resolution determination module configured to based upon the transmission characteristic of the first signal transmission, determine a corresponding at least one protocol, the determine template and data resolution module further configured to determine a data resolution based upon the transmission characteristic, form a second data transmission according to the at least one corresponding protocol, and insert sensed date into the second data transmission according to the resolution; and
a transmitter with an output and coupled to the determine template and resolution determination module, the transmitter configured to transmit the second data transmission at the output, wherein the second data transmission corresponds to a customizable burst that includes a plurality of frames, and each of the frames includes sensed tire pressure monitoring information and wherein portions of the burst are compatible with multiple types of receivers.
