  • System for measuring life expectancy of a tire condition monitoring system
    Patent number: 7714707
    Abstract: A system (10) is provided for monitoring a remote tire monitoring sensor. The system includes a tire-based unit (16) having a sensor (42) and transmitter (44) that receives power from a power supply (18) located within the tire-based unit (16). The transmitter (44) transmits a signal (22) relating to a parameter measured by the sensor (42). The system (10) further includes a controller (36) that evaluates the life of the power supply (18) by monitoring energy usage of the power supply (18) by counting the number of occurrences in which the energy usage is above a prescribed amount (59) and comparing the number of occurrences to an energy threshold (60).
    Type: Grant

  • Non-load driven fault monitor for electrical circuits
    Patent number: 7071699
    Abstract: A fault monitor for the load portion of an electrical circuit may be connected to an existing circuit by a single connection, and may detect flaws within the load portion of the circuit through the detection of changes in voltage through a resistor, caused by changes in current flow due to changing resistance within the load portion of the circuit.
