Ear-wearable device of measuring physiological signals disclosed. The ear-wearable device may include a body to be placed on a back of an ear, an ear hook, having one end coupled to the body and placed in front of the ear to fix the body to the ear, an oximeter, configured for measuring a saturation of percutaneous oxygen and having a detection surface disposed near the other end of the ear hook, an in-ear thermometer being connected to the body by a flexible cord, and a wireless transceiver, configured for wirelessly transmitting measurements of the oximeter and the in-ear thermometer.

The technology involves scaffold structures used for in-ear sensor systems. Such systems that can perform biometric signal detection or act as a human-computer interface. Scaffolding arrangements minimize the amount of material placed in the ear while providing a secure fitting device that can be worn for hours, days or longer in order to provide maximal benefit to the wearer. The scaffolding includes a “C”-shaped arcuate curvature for at least part of the housing. This configuration can act as a natural leaf spring to help maintain the housing in contact with different points along the ear. Sensors are located along various points of the scaffolding for use in different diagnostic situations. Different components of an on-board sensor input and processing system can be distributed along different parts of the scaffolding. Such structures beneficially minimize ambient sound occlusion and avoid the need of an exterior strap or clip worn around the ear.

An ear-wearable device includes a photoplethysmography (PPG) sensor. One or more processors of the ear-wearable device are configured to determine, based on sample values of a PPG signal generated by the PPG sensor, whether a user of the ear-wearable device has fallen.

An embodiment of the invention provides a wireless in-ear utility device that rests in the user's ear canal near the user's eardrum. The in-ear utility device may be configured in a variety of ways, including, but in no way limited to a smart in-ear utility device, a flexible personal sound amplification product, a personal music player, a “walkie-talkie” and the like.

A system which includes a first sensor placed proximate to a perfusion field of an artery receiving blood which emanates from the cranial cavity is configured to monitor pulsations of the artery receiving blood which emanates from the cranial cavity artery. A second sensor placed proximate to a perfusion field of an artery which does not receive blood emanating from the cranial cavity and approximately the same distance from the heart as the first sensor configured to monitor pulsations of the artery which does not receive blood emanating from the cranial cavity. A third sensor placed distally from a heart is configured to monitor pulsations of a distal artery. A processing system responsive to signals from the first, second, and third sensors is configured to determine intracranial pressure.

The present disclosure relates to systems and methods for determining the renal glomerular filtration rate or assessing the renal function in a patient in need thereof. The system includes a computing device, a power supply, one or more sensors, and at least one tracer agent that fluoresces when exposed to electromagnetic radiation. The electromagnetic radiation is detected using the sensors, and the rate in which the fluorescence decreases in the patient is used to calculate the renal glomerular filtration rate in the patient.

Methods and apparatus disclosed herein use a filtering technique to improve the accuracy of the results achieved when processing data provided by a physiological sensor. The disclosed filtering technique corrects many of the accuracy problems associated with physiological sensors, particularly PPG sensors. Broadly, the filtering technique adjusts a current filtered estimate of a physiological metric as a function of a rate limit based on a comparison between an instantaneous estimate of the physiological metric and the current filtered estimate.

The present invention relates to SMART headphones. More particularly, the present invention relates to SMART audio headphones system adapted to modulate personal playlists that adapt to a users preferences, particularly to their state of mind and/or emotions.

Disclosed is an audio-headset for acquisition of a bio-signal from a subject, including a first earpiece; a second earpiece; an arch connecting the first earpiece and the second earpiece; the arch including a hub (4); wherein the arch, the first earpiece and the second earpiece are configured so that the earpieces are placed over a subject's ears when the audio headset is worn by the subject; and at least one posterior branch (1) having a first end extending from the hub and a second free end; the at least one posterior branch (1) including a concave surface with a radius of curvature, a collapsed state when the headset is not worn by the subject and an expanded state when the headset is worn by the subject.

A smart glass including photoplethysmography and electrocardiogram sensors to determine a health condition of the user is provided. The smart glass includes a frame for holding two eyepieces, the frame having two nose pads to rest on a user's nose, and two arms to rest on two user's ears, a sensor mounted on at least one of the nose pads or the arms, and configured to collect an optical signal from a user's blood vessel, and a processor configured to obtain a waveform from the optical signal or the electrical signal, and to determine a cardiovascular parameter based on the waveform.
