  • Patent number: 11540734
    Abstract: An apparatus for measuring a performance metric of a heart includes a housing, a tactile sensor, a finger clamp, a linear actuator, and a controller. The tactile sensor measures blood pressure pulsatility in a digital artery of a finger via applanation tonometry and outputs pulsatility signals indicative of the blood pressure pulsatility. The finger clamp extends from the housing to clamp the finger against the tactile sensor with the digital artery aligned over the tactile sensor. The linear actuator drives the finger clamp with a clamping force directed along a linear path. The controller is coupled to the tactile sensor and the linear actuator to control the clamping force and to generate pulsatility data, based upon the pulsatility signals, from which the performance metric of the heart may be determined.

  • Patent number: 11526996
    Abstract: Example embodiments allow for fast, efficient motion-magnification of video streams by decomposing image frames of the video stream into local phase information at multiple spatial scales and/or orientations. The phase information for each image frame is then scaled to magnify local motion and the scaled phase information is transformed back into image frames to generate a motion-magnified video stream. Scaling of the phase information can include temporal filtering of the phase information across image frames, for example, to magnify motion at a particular frequency. In some embodiments, temporal filtering of phase information at a frequency of breathing, cardiovascular pulse, or some other process of interest allows for motion-magnification of motions within the video stream corresponding to the breathing or the other particular process of interest. The phase information can also be used to determine time-varying motion signals corresponding to motions of interest within the video stream.

  • Patent number: 11219412
    Abstract: This document describes techniques for, and systems that enable, in-ear health monitoring. The techniques described herein enable early detection of health conditions (e.g., contagious disease) through use of an in-ear health-monitoring and audio device. These techniques prompt a user, often through the user's smart phone, to listen to audio content through the device, which also takes the user's temperature. Through repetitive use, the techniques are capable of determining a temperature differential for the user, which aids in early detection of a contagious disease or other malady.

  • Patent number: 11103221
    Abstract: An ultrasonic imaging method includes activating a transmit aperture within a multi-element transducer array, transmitting one or more ultrasonic beams along scan direction(s) that span the region of interest, for each transmit event, receiving ultrasound echoes from each element of a receive aperture, grouping the receive channel echo data into two or more sets corresponding to different receive sub-apertures, combining each sub-aperture data set to generate partially focused echo-location data for one or more reconstruction lines, and storing all the sub-aperture echo data sets during a storage period in a format that can be retrieved for later analysis.

  • Patent number: 10376195
    Abstract: This document describes automated nursing assessments. Automation of the nursing assessment involves a nursing-assessment device that makes determinations of a person's mood, physical state, psychosocial state, and neurological state. To determine a mood and physical state of a person, video of the person is captured while the person is positioned in front of an everyday object, such as a mirror. The captured video is then processed according to human condition recognition techniques, which produces indications of the person's mood and physical state, such as whether the person is happy, sad, healthy, sick, vital signs, and so on. In addition to mood and physical state, the person's psychosocial and neurological state are also determined. To do so, questions are asked of the person. These questions are determined from a plurality of psychosocial and neurological state assessment questions, which include queries regarding how the person feels, what the person has been doing, and so on.

  • Publication number: 20180296163
    Abstract: This document describes ways in which to alter physiological signals to address corrupt, noisy, or otherwise faulty data. By so doing, accuracy and robustness in sensing and assessing a patient's cardiovascular health can be improved. These improved assessments permit better measures of health, such as relevant hemodynamics understood by heart rates, heart rate variability, cardiac arrhythmias, blood pressures, pulse-wave velocities, arterial stiffness, cardiac valve timing, thoracic fluids, ballistocardiogram force, photo-plethysmograms, blood oxygenation, and pressure-volume loops.

  • Patent number: 10080528
    Abstract: This document describes optical central venous pressure measurement. To determine the central venous pressure (CVP) of a person optically, video of a right side of the person's neck is captured. By way of example, a medical professional records a video of the right side of the person's neck using a smartphone. The right side of the person's neck is captured because it is where the person's external and internal jugular veins are located and pulsatile motions that are usable to measure CVP occur in those veins. The video is then processed according to video motion amplification techniques to generate a reconstructed video of the right side of the person's neck. In the reconstructed video, the pulsatile motion of the person's venous system that occurs at the right side of their neck is visually amplified. Using the reconstructed video, measurements are made of a distance between a peak of the visually-amplified pulsatile motion and an anatomical feature of the person.

  • Patent number: 9826932
    Abstract: This document describes automated abdominojugular reflux (AJR) testing. To automate AJR tests, a pressure cuff wrapped around a person's abdomen applies pressure while video of their neck is captured. By way of example, a medical professional wraps a pressure cuff around the person's abdomen and records video of the person's neck using a smartphone, which communicates with the pressure cuff to synchronize the application of pressure with video capture. The video is processed to detect and track the response of jugular venous pulse (JVP), which is compared to AJR test thresholds to determine test results. While determining JVP, and thereby results of AJR tests, from reconstructed videos may not result in data that is as accurate as invasive intra-heart tests, it requires little if any risk to patients and is easy for medical professionals to perform. Further, these techniques enable AJR tests to be performed automatically and without relying on estimates made by skilled medical professionals.
