  • Phase-locked loop (PLL)-type resolver/converter method and apparatus
    Patent number: 10187067
    Abstract: An apparatus and method for determining an angle ? an estimate of a true angle ? from a resolver excitation signal Vex(t)=A sin(?t) and modulated resolver output signals Vs(t,?)=A×sin(?)×sin(?t) and VC(t,?)=A×cos(?)×sin(?t), where ? is an angular frequency and t is time, is provided. The apparatus may include a converter comprising a closed loop phase-locked loop (PLL) system configured to produce an angle ? and two digital signals BitØ(?) and Bit1(?) for estimating the true angle ? using Vex(t), Vs(t,?) and VC(t,?) signals.

  • System, apparatus, method, and computer readable medium for monitoring volume and rate of air drained from a body
    Patent number: 10172982
    Abstract: Air drained from a patient's body can be measured after a surgical operation or trauma. The volume of air drained from the body can be determined from the weight of a vessel that has receive effluent drained the body and the volume of air that has escaped from the vessel. The effluent can include any one or a combination of air and liquid.
