Latest Patents

Zemin Liu holds a patent for a "System for sensing arterial pulse waveform." This invention includes an offset calibration circuitry designed to compensate for the offset voltage of a resistive bridge sensor. The system features a first current digital to analog converter (IDAC) connected to a first successive approximation register (SAR), along with a second IDAC linked to a second SAR and an SAR controller circuitry. The first IDAC is configured to connect to a negative voltage port of the resistive bridge sensor, while the second IDAC connects to a positive voltage port. The SAR controller circuitry adjusts each bit of both SARs based on the output of a comparator, which compares voltages to a common mode voltage. This innovative approach allows for more precise measurements in medical applications.
