  • Patent number: 11195433
    Abstract: The present disclosure provides a system that quantitatively tracks an individual's diet and exercise using smart devices (phones, watches, and other wearables). Unlike existing programs, which work in energy units (calories), the present system works in mass units (grams) and satisfies the fundamental physics law of conservation of mass. Food ingested is tracked as well as exercise in order to place the user on a quantitative, custom diet that safely and effectively results in weight loss. In addition to rigorously treating the problem of weight loss by addressing the physics that underlies diet and exercise, the system empirically learns about the user over time such that performance may be optimized.

  • Patent number: 10918329
    Abstract: Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14, 16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.

  • Patent number: 10850052
    Abstract: A processor obtains input of a logistically attainable end tidal partial pressure of gas X (PetX[i]T) for one or more respective breaths [i] and input of a prospective computation of an amount of gas X required to be inspired by the subject in an inspired gas to target the PetX[i]T for a respective breath [i] using inputs required to utilize a mass balance relationship, wherein one or more values required to control the amount of gas X in a volume of gas delivered to the subject is output from an expression of the mass balance relationship. The mass balance relationship is expressed in a form which takes into account (prospectively), for a respective breath [i], the amount of gas X in the capillaries surrounding the alveoli and the amount of gas X in the alveoli, optionally based on a model of the lung which accounts for those sub-volumes of gas in the lung which substantially affect the alveolar gas X concentration affecting mass transfer.

  • Patent number: 10750738
    Abstract: Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.

  • Patent number: 10667722
    Abstract: The fat burning analyzer includes a sampling part, an analysis unit and a processing unit. The sampling part collects a breath sample from the user, information on the conditions of the breath sample collection, and provides a sampling signal correlated to the collection condition of the breath sample. The analysis unit provides a detection signal corresponding to an acetone concentration in the collected breath sample and, as such, provides information on the breath acetone of the user (during exercise or resting). The processing unit receives the sampling signal and/or detection signal, and evaluates the sampling signal and/or the detection signal. The evaluation provides information correlated to the fat burning intensity of the user. These information can be provided as an output signal by the processing unit. Accordingly, the processing unit is equipped to provide an output signal correlated to the fat burning intensity of the user.
