  • Patent number: 9974449
    Abstract: A method and apparatus for indirect, quantitative estimation of beat-to-beat arterial blood pressure utilizing the individualized rectifying technique. A function TK=H(P) that describes the relationship between Korotkoff's sound delay time Tk and cuff pressure P is obtained by measuring the different cuff pressure P and corresponding Tk in the Korotkoff's sound sensor that is distal to the cuff. Keep the cuff pressure at a constant value Pm, the blood pressure variance can be calculated using the Korotkoff's sound delay time Tkm, according to the function Tk=H(P). The invention can measure the beat-to-beat artery blood pressure indirectly. The technique can be applied to obtain individual coefficient of regress equation for continuous arterial blood pressure measurement by the instantaneous blood pressure fluctuation, which make the rectifying technique more safe, effective and less erroneous. The technique makes the operation of noninvasive continuous blood pressure measurement for long time more practical.

  • Publication number: 20180138584
    Abstract: Disclosed are a system, apparatus, and method for modifying a dipole antenna to comprise unequal arm lengths for matching the condition of two different dielectric materials such as air and human body. The modified dipole antenna is built in a cylindrical pipe shape dipole that has a hollow center to let wires pass through it and has little to no effect in antenna performance The antenna can be bent in different shape to fit in any wireless product of any shape or size. The antenna is designed to provide a stable radiation at one side and partial radiation at front side even with human body intervention. Further the antenna can be combined with another similar antenna via a power splitter/divider to form a full 360 degree radiation pattern even in presence of a human body in proximity.
