Abstract

One general aspect includes a tethered temperature sensor for use within a vehicle track. The tethered temperature sensor includes one or more sensors for measuring temperature located in a high strain and high temperature region of the vehicle track. The sensor also includes circuitry configured to control and/or monitor the one or more sensors and located in a low strain and low temperature region of the vehicle track. The sensor also includes a housing to contain the circuitry. The sensor also includes an encapsulating material that fills an interior of the housing.

First claim

What is claimed is:

1. A tethered temperature system comprising:
a sensor for measuring temperature of a rubber product, the sensor of one or more sensors;
circuitry configured to control and/or monitor the one or more sensors;
a conductive tether embedded within the rubber product and configured to connect to the sensor, the conductive tether is configured to operate as an antenna; and
the conductive tether is comprised of a flexible conductive material and provides at least 300 percent elongation; and
the circuitry within a housing and encased in a ceramic potting material having a thermal conductivity lower than that of rubber;
the sensor exposed to an outer shell;
the sensor positioned toward an edge portion of the rubber product and the circuitry positioned toward a middle portion of the rubber product.

2. The system of claim 1 , the conductive tether configured to electrically connect the sensor to the circuitry.

3. The system of claim 1 , further comprising a transceiver configured to transmit measured temperatures from the one or more sensors.

4. The system of claim 3 , the transceiver configured to transmit using frequency shift modulation (FSM).

5. The system of claim 3 , the transceiver configured to transmit using frequency modulation (FM).

6. The system of claim 3 , the transceiver configured to transmit the measured temperatures to a tire pressure monitoring system.

7. The system of claim 1 , the sensor and the circuitry positioned within a single drive lug of the rubber product.

8. The system of claim 1 , the sensor positioned within a first drive lug of the rubber product and the circuitry positioned within a second drive lug of the rubber product.

9. The system of claim 1 , the circuitry positioned within a region of the rubber product having temperatures less than about 150 degrees Fahrenheit.

10. The system of claim 1 , the circuitry positioned within a strain region having a strain less than about 100 percent.

11. The system of claim 1 , further comprising a transceiver utilize one or more communication protocols selected from a group comprising, radio frequency (RF), RFID, Bluetooth, WiFi, 4G and 5G for communicating measured temperature.

12. The system of claim 1 , the sensor having activation based on motion.

13. The system of claim 1 , the rubber product comprising a tire.

14. The system of claim 1 , the rubber product comprising a hose.

15. The system of claim 1 , the rubber product comprising a conveyor belt.
