Latest Patents

Hang Liu holds a patent for a "Complex wavelet filter based power measurement and calibration system." This system provides power and line frequency measurements by utilizing a bandpass filter with complex voltage and current outputs. From these outputs, real and imaginary power components can be determined. The calibration of the filter can be omitted if a complex wavelet filter is employed, allowing for accurate line frequency determination for downstream applications. A processor that receives data from the filter's output can compute real and imaginary power, power factor, and line frequency. The filter can be implemented through a processor executing program instructions or a digital circuit, which may include a CORDIC rotator for computing the current-to-voltage phase relationship.
