The apparatus comprises a personal digital assistant (PDA) having computer program code adapted to assist in at least one of calorie counting, meal selection, meal suggestion, weight monitoring, weight loss or gain monitoring, fat consumption monitoring, sugar consumption monitoring and salt consumption monitoring. The PDA also includes computer program code adapted to display historical data regarding at least one of calorie counting, meal selection, meal suggestion, weight monitoring, weight loss or gain monitoring, fat consumption monitoring, sugar consumption monitoring and salt consumption monitoring. Numerous other embodiments are provided, as are methods, systems and computer program products.

A dermal imaging system coordinates operation of an illumination unit, one or more lenses, and a camera to capture a sequence of images of an area of interest on a skin surface. The system automatically tags each image in the sequence of images. The tag for each image identifies a light source, an illumination angle, and a filter selected for capturing the image. The system automatically selects at least one image from the sequence of images, and analyzes the selected image from the sequence of images to provide a recommended skin disease diagnosis.

A method for operating a compressive recovery device. The method including receiving activity data of a user, providing a recommended recovery activity based on the activity data, wherein a primary goal of the recovery activity is to facilitate physiological recovery of the user, and controlling a compressive recovery device to perform the recovery activity on the user.

A mobile terminal and a control method therefor are disclosed. An embodiment of the present invention comprises: a detection unit for monitoring a stress index on the basis of a user's biometric information and detecting a first interval where the rate of change at which an increased stress index decreases exceeds a reference range; a storage unit for storing context information corresponding to the detected first interval; and a control unit for, when a second interval where the rate of change at which the increased stress index decreases is less than the reference range occurs, generating stress relief information using the stored context information and outputting the generated stress relief information.

There is disclosed a device for imaging a body. In one arrangement, the device comprises a controller, storage storing electronic program instructions for controlling the controller, a display for displaying a user interface, and an input means. In one form, the controller is operable, under control of the electronic program instructions, to receive input via the input means, where the input comprises a first representation of the body, to process the first representation, to generate a second representation of the body on the basis of processing of the first representation, and to display the generated second representation via the display.

A method and system for removing corruption in photoplethysmogram (PPG) signals for monitoring cardiac health of patients is provided. The method is performed by extracting photoplethysmogram signals from the patient, detecting and eliminating corruption caused by larger and transient disturbances in the extracted photoplethysmogram signals, segmenting photoplethysmogram signals post detection and elimination of corruption caused by larger and transient disturbances, identifying of inconsistent segments from the segmented photoplethysmogram signals, detecting anomalies from the identified inconsistent segments of the photoplethysmogram signals, analysing the detected anomalies of the photoplethysmogram signals and identifying photoplethysmogram signal segments corrupted by smaller and prolonged disturbances.

A Virtual Patient Care (VPC) platform establishes a video call between a patient application and a clinician application. During the video call Selfie Vitals are measured using the selfie camera on the patient's smartphone. The patient's video is paused to the clinician and sent to Artificial Intelligence (AI) engines using remote Photoplethysmography (rPPG) or Transdermal Optical Imaging (TOI) techniques to extract vital signs. Pulse, blood pressure, oxygen saturation, and respiration rate vital signs are generated and displayed on the clinician' s user interface. Audio continues while video conferencing may be paused during vitals measurement. The patient's smartphone can perform pre-processing to generate metadata that is sent to a VPC server with more powerful AI engines. Vitals measurement can be initiated by the patient selecting a Selfie Vitals icon on a patient user interface during the video conference call or can be initiated by the clinician.

A display apparatus includes a first pixel, a second pixel, a light sensor, and a light shield. The first pixel has a first light-emitting device which includes a first emission layer that emits light in a first wavelength band in a first direction. The second pixel has a second light-emitting device which includes a second emission layer to emit light in a second wavelength band in a second direction different from the first direction. The second emission layer is below the first emission layer of the first light-emitting device. The light sensor senses light in the second wavelength band emitted from the second pixel and reflected by an object. The light shield is arranged along a light path incident to the light sensor.

The location of a user's head, for purposes such as head tracking or motion input, can be determined. For example, a computing device (e.g., a tablet, mobile phone, etc.) can utilize one or more detectors or other image classifiers to detect the presence objects such as features of the face in images captured by one or more cameras of the computing device. Based on the detected feature(s), the subject technology provides embodiments for detecting a heart rate of the user of the computing device without requiring invasive procedures or addition sensors on the computing device by selecting a region of interest for analyzing color or other image data measurements over a period of time. Changes in color at the select region of interest may be further processed to extract a user's heart rate using techniques described further herein.

Systems and methods for detecting a biological analyte are provided. The biological analyte can be, for example, cortisol. Detection can be achieved without external labels/mediators. Microfluidic systems can be incorporated into the optical sensor for enhanced point-of-care applications. The sensor can be used in a variety of low-power electronics for wearable applications.
