A portable smart device designed to be held by a user or worn by the user for determining a quality of a meditation session. The portable smart device including a heart rate sensor configured to detect heart rate of the user and output a heart rate signal, and an electronic computing unit coupled to the heart rate sensor. The electronic computing unit including a processor configured to analyze the heart rate signal of the user during the meditation session to determine two or more physiological parameters including at least one of breathing rate, breathing rate variability, heart rate, heart rate variability and vagal tone, and combine the two or more physiological parameters to determine a meditation session quality index (SQI) that indicates the quality of the meditation session.

The present disclosure provides computing systems and techniques for indicating an emotional and/or environmental state of a user in a digital messaging application. A computing device can determine an emotional and/or environmental state of a first user responsive to reading or responding to a message and can convey the determined emotional and/or environmental state to a second computing device, to be transiently presented by the second computing device.

Provided are foldable electronic device and method for estimating bio-information by using the same. The foldable electronic device may include: a main body part including a first main body and a second main body that are configured to be folded toward each other or unfolded from each other along a fold line where the first main body and the second main body meet; an image sensor part including a first image sensor and a second image sensor which are disposed at the first main body; and a processor configured to obtain a contact image of an object from the first image sensor disposed at the first main body and obtain an image of a marker that is displayed on the second main body, from the second image sensor disposed at the first main body, when the object is in contact with the first image sensor and the main body part is folded along the fold line, and estimate bio-information based on the contact image of the object and the image of the marker.

Among other thing, the present invention provides solution to the problem, particularly, the present invention certain surfaces and certain sample holder to improve the sensitivity, speed, and easy-to-use of an optical signal based assays, such as colorimetric assays or fluorescence assays.

A computer program and computer-based system for remotely assessing oral health of a person by obtaining at least one digital image (1) of the person's oral cavity and additional non-image data (2) comprising anamnestic information about the person (30). The digital images (1) are segmented using statistical image segmentation algorithms (101,102) to extract visible segments (3), which are further processed to predict any invisible segments (6). The resulting segments are processed by a statistical object detection algorithm (104) using the non-image data (2) as further input to identify dental features (7), which are filtered to select only risk-related dental features (8) using a risk database (9) and mapped to respective tooth regions (11) or oral cavity regions (12) in an Oral Risk Atlas (10).

A method for guiding deep breathing may include receiving a request from a user to initiate a deep breathing exercise on a user-controlled device. The method may include monitoring deep breathing using one or more sensors on an ear-worn device in response to initiating the deep breathing exercise. Examples of sensors include at least one of a motion detector, a microphone, a heart rate sensor, and an electrophysiological sensor. The method may further include initiating an end to the deep breathing exercise. The method may be used with various hearing systems including an ear-worn device and optionally a user-controllable device, such as a smartphone.

A method, system, and/or apparatus for automatically monitoring for possible infection or other physical health concerns, such as from Covid-19. The method or implementing software application uses or relies upon location information available on the mobile device from any source, such as cell phone usage and/or other device applications. The method and system automatically uses and/or learns user location and activity patterns and determines and infection risk or illness-based deviation that can be communicated as a warning to community members.

A method and apparatus for stimulating neural activity in the brain of a user of an apparatus with a display screen by causing at least one portion of the display screen to flicker in a controlled manner and utilizing the apparatus to measure an effect on a user exposed to the flicker for a time.

Systems and methods for screening a subject for neuropathology associated with COVID-19. The method can include providing neurophysiological stimuli to the subject, measuring response by the subject to the neurophysiological stimuli, comparing the measured responses to a reference, determining whether the subject demonstrates abnormal or changed responses to the neurophysiological stimuli according to whether the measured responses differ from the individual's baseline or from the reference by one or more thresholds, and providing an alert according to whether the subject has abnormal or changed responses to the neurophysiological stimuli, wherein the alert comprises an intervention associated with COVID-19.

Devices, systems and methods are disclosed that allow a patient to self-treat a medical condition, such as migraine headache, by electrical non-invasive stimulation of a nerve, such as the trigeminal nerve. A system comprises one or more electrodes configured for contacting an outer skin surface of a patient and a stimulator coupled to the one or more electrodes. The stimulator is configured to transmit an electrical impulse from the electrodes through the outer skin surface to a target site within a patient. A software application coupled to the stimulator. The software application may, for example, be downloadable onto a mobile device and may allow the user to transmit data to and from the stimulator and/or control operation of the stimulator.
