Abstract
A wireless sealant and pressure monitoring system for tubeless tires includes an integrated wireless component positioned inside a tubeless tire. The integrated wireless component comprises a first and second conductive sealant sensor pad, a current sensor, and a pressure sensor. The current sensor measures an electrical current flowing between the first and second sealant sensor pads, providing a measure of the sealant level inside the tire. The pressure sensor measures the pressure inside the tubeless tire. The system also includes a wireless transmitter in communication with the current sensor and pressure sensor, configured to transmit data corresponding to the measured electrical current and measured pressure.

A wireless monitoring system for tubeless tires, comprising:
- a sensor module configured to be positioned within a tubeless tire, comprising:
- sealant detection elements configured to detect a sealant level and generate sealant level data;
- a pressure sensor configured to measure internal tire pressure and generate pressure data;
- and
- a wireless transmitter configured to transmit the sealant level data and the pressure data,
- wherein the sealant detection elements are configured to measure electrical conductivity within the tubeless tire to detect the sealant level, and
- wherein the sensor module is configured to:
- detect changes in conductivity during tire rotation;
- correlate the changes in conductivity with sequential positions during incremental rotation of the tubeless tire to generate a sealant distribution profile;
- and
- determine a sealant level based on a rate of change of conductivity across the sealant distribution profile.
A method for monitoring a tubeless tire, comprising:
- detecting a sealant level, within the tubeless tire by measuring electrical conductivity, and generating detected sealant level data based on the measured electrical conductivity, the detecting of the sealant level comprising:
- applying a periodic voltage between conductive sensor pads;
- measuring a pulsed current flow between the conductive sensor pads;
- determining sealant presence based on the measured pulsed current flow;
- and
- mapping sealant distribution during tire rotation;
- measuring internal tire pressure to generate measured pressure data;
- wirelessly transmitting the detected sealant level data and the measured pressure data as transmitted data;
- and
- processing the transmitted data to monitor tire conditions.
