  • Publication number: 20250093236
    Abstract: A system for monitoring the condition of vehicle tires is disclosed. A method for monitoring the state of vehicle tires is also disclosed. The system includes a sensor unit, a sensor hub connected to the sensor unit, a processing unit and a power management unit. The sensor unit further includes plurality of sensors, an analog front end for processing and converting the analog signals to digital data, and a communication unit. A signal thresholding circuit is part of the analog front end. The condition of vehicular tires are monitored by determining the revolutions per minute (RPM) as well as the absolute number of revolutions of the tires. This facilitates in detecting bad road conditions, air leakage from tire, temperature and pressure of the tire and issue warnings to the user.

  • Patent number: 6784725
    Abstract: A switched capacitor current reference circuit generates an almost constant reference current across the parameters of process, voltage and temperature. A reference voltage is generated within the circuit, which eliminates the need for an external reference voltage. The reference current is generated by applying the reference voltage across a resistor emulated with a pair of switched capacitor circuits.
