Patent number: 11587672Abstract: Introduced here are diabetes management platforms able to guide people with diabetes toward a glycemic target. Rather than state the absolute amount of glucose within the blood, the diabetes management platform can instead produce personalized glycemic goals based on the physiological data associated with an individual. For example, if the diabetes management platform determines that the time spent within a first glycemic range exceeds a specified threshold, then the diabetes management platform may recommend that the individual attempt to keep their blood glucose level within a second glycemic range. Generally, the second glycemic range is closer than the first glycemic range to a target glycemic range corresponding to a healthy glycemic state.Type: GrantFiled: August 9, 2019Date of Patent: February 21, 2023Assignee: Verily Life Sciences LLCInventors: Nikhil Roy, Howard Zisser

Patent number: 11517256Abstract: A method of characterizing a patient's disordered breathing during a sleeping period includes performing a first partial characterization of a time axis of an audio signal in order to learn the most prominent and highly relevant events. Only at a later stage, i.e., after sufficient observation of the highly relevant events, is a full segmentation of the entire time axis actually carried out. Linear prediction is used to create an excitation signal that is employed to provide better segmentation than would be possible using the original audio signal alone. Warped linear prediction or Laguerre linear prediction is employed to create an accurate spectral representation with flexibility in the details provided in different frequency ranges. A resonance probability function is generated to further characterize the signals in order to identify disordered breathing. An output includes a characterization in any of a variety of forms of identified disordered breathing.Type: GrantFiled: December 26, 2017Date of Patent: December 6, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Albertus Cornelis Den Brinker, Okke Ouweltjes, Armin Gerhard Kohlrausch, Koray Karakaya
