Patent number: 11344214Abstract: Wearable pulse pressure wave sensing devices are presented that generally provide a non-intrusive way to measure a pulse pressure wave travelling through an artery using a wearable device. In one implementation, the device includes an array of pressure sensors disposed on a mounting structure which is attachable to a user on an area proximate to an underlying artery. Each of the pressure sensors is capable of being mechanically coupled to the skin of the user proximate to the underlying artery. In addition, there are one or more arterial location sensors disposed on the mounting structure which identify a location on the user's skin likely overlying the artery. A pulse pressure wave is then measured using the pressure sensor of the array closest to the identified location.Type: GrantFiled: June 29, 2020Date of Patent: May 31, 2022Assignee: Microsoft Technology Licensing, LLCInventors: T. Scott Saponas, Dan Morris, Nicolas Villar, Shwetak Patel, Greg R. Smith, Desney Tan, Orestis Vardoulis, Sidhant Gupta

Publication number: 20220054029Abstract: Systems are provided for determining the pulse wave velocity of blood flowing within a blood vessel. Disclosed systems may include first and second sensors at spaced apart locations in the blood vessel. The first sensor, in a first position, x1, in the vessel, r is configured to obtain a first area measurement, m1, of the vessel. The second sensor, in a second position, x2, in the vessel, is configured to obtain a second area measurement, m2, of the vessel. Disclosed systems may also include a processor configured to determine the pulse wave velocity of the vessel based on the first and second area measurements.Type: ApplicationFiled: December 16, 2019Publication date: February 24, 2022Inventors: Fiachra M. Sweeney, Orestis Vardoulis

Publication number: 20210396605Abstract: Various embodiments are directed to sensor apparatuses and methods thereof. An example sensor apparatus includes a plurality of capacitors and sensor circuitry. The plurality of capacitors including a first substrate having a plurality of first electrodes, a second substrate having a second electrode, and a dielectric material, and with the plurality of first electrodes and the second electrode being separated by the dielectric material. The plurality of first electrodes are aligned with respect to the second electrode such that each of plurality of first electrodes form one of the plurality of capacitors with the second electrode. The sensor circuitry is coupled to the plurality of capacitors to differentiate between normal and shear forces applied to apparatus based on a pattern of impedance responses of each of the plurality of capacitors formed by the second electrode and the plurality of first electrodes.Type: ApplicationFiled: October 25, 2019Publication date: December 23, 2021Inventors: Orestis Vardoulis, Zhenan Bao, Clementine M. Boutry, Marc Negre, Alex L. Chortos

Publication number: 20210030299Abstract: Provided herein are systems and methods for automatically determining if a subject is having a stroke. A subject's brain may be monitored with sensors or electrodes to acquire biopotential voltage data. EEG data, power spectrum data and ratios and differences thereof, principal component analysis (PCA) features, and/or other engineered features may be extracted scored with automated machine learning systems. A classifier can identify and/or output if the subject is having a stroke. The subject or a third party can be automatically notified that the subject is having a stroke.Type: ApplicationFiled: April 8, 2019Publication date: February 4, 2021Inventors: Urs Hendrik NABER, Orestis VARDOULIS, Patrick Clyne THOMPSON, Lily Ayodele ROBERTS
