  • Patent number: 11219378
    Abstract: A method and device is provided for the continuous estimation of the blood pressure using a noninvasive technique. The method involves sensing of the displacement signal generated by the palpation of the radial artery. The radial artery is modelled as a cylindrical voight type viscoelastic tissue for the estimation of the personalized blood pressure. The model includes the displacement signal and a set of parameters as an input. The set of parameters include a mean radius of the artery, a radius at zero mmHg, a viscoelastic damping parameter, an elasticity of the artery and a thickness of wall of artery. The method involves the optimization of the set of parameters using heuristic optimization techniques, which helps in the estimation of the systolic and diastolic blood pressure. The method and device can also be personalized for individualized monitoring and estimation of the blood pressure of the person.

    Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference.

  • Patent number: 10512408
    Abstract: A computer-implemented method for characterizing circulatory blood volume is disclosed. The method has the steps of acquiring a biological signal that emulates the arterial pulse wave from a sensor. Two derived parameters, circulatory stress, which reflects a harmonic of heart rate, and circulatory blood flow, which reflects the amplitude of the unprocessed biological signal, are extrapolated from the biological signal, and are each compared to a threshold value and assessed to determine an adequacy of circulatory blood volume. In embodiments, the assessment of circulatory blood volume is used to manage a patient's cardiovascular autoregulatory function or the adequacy of transfer of fluids to and from the circulatory system, with the ultimate goal of achieving a circulatory blood volume that adequately supplies the demands of the patient's tissues and organs.

  • Patent number: 10463278
    Abstract: Systems and methods are provided for calculating point values for users who participate in activities. An activity is first captured with a sensor. A processor classifies the activity by comparing a sensor signal to templates. Once the activity is classified, an activity factor is selected. Point values are then calculated as a function of the activity factor and duration of the activity. If a predetermined criteria is met, such as inactivity for a predetermined time period, points may be deducted.

  • Patent number: 10342437
    Abstract: A system for detecting dehydration, hemorrhaging, and increases in blood volume comprising monitors the time difference between the arrival of the primary left ventricular ejection pulse (pulse T1) and the arrival of the iliac reflection (pulse T3) to determine an arterial pulse parameter which is the time difference between T1 T3. Changes in T3 minus T1 are indicative of something happening to blood volume. If the T1-3 value goes up and the patient is on an infusion system, it can be an indication of having too much fluid pumped and if T1-3 is lower than it should be for an individual, they are either dehydrated (which can result in decreases in blood volume), they are hemorrhaging, or they have hemorrhaged. A downtrend in T13 can tell whether someone is continuing to hemorrhage.
