A cognitive function evaluation device includes: an obtainment unit configured to obtain speech data indicating speech uttered by a subject; a calculation unit configured to extract a plurality of vowels from the speech data obtained by the obtainment unit, and calculate, for each of the plurality of vowels, a feature value based on a frequency and an amplitude of at least one formant obtained from a spectrum of the vowel; an evaluation unit configured to evaluate a cognitive function of the subject from the feature value calculated by the calculation unit; and an output unit configured to output an evaluation result of the evaluation unit.

An optical apparatus has an OCT imaging apparatus with a first light source for low coherence light of wavelengths above a threshold wavelength and a signal detector that obtains an interference signal between low coherence light from the sample and low coherence light reflected from a reference. A surface contour imaging apparatus has a second light source that emits one or more wavelengths of surface illumination below the threshold wavelength, a camera to acquire images from illumination reflected from the sample and a probe that has a raster scanner wherein the low coherence light and the surface illumination share the same path from the raster scanner to the sample. A processor coordinates activation of the light sources, actuation of the scanner, and acquisition of data and the camera and follows instructions to display, store, or transfer images from the acquired data.

Systems and methods for monitoring food intake include an air pressure sensor for detecting ear canal deformation, according to some implementations. For example, the air pressure sensor detects a change in air pressure in the ear canal resulting from mandible movement. Other implementations include systems and methods for monitoring food intake that include a temporalis muscle activity sensor for detecting temporalis muscle activity, wherein at least a portion of the temporalis muscle activity sensor is coupled adjacent a temple portion of eyeglasses and disposed between the temple tip and the frame end piece. The temporalis muscle activity sensor may include an accelerometer, for example, for detecting movement of the temple portion due to mandibular movement from chewing.

The plurality of sensors senses a plurality of health parameters from an associated user, in real time, to generate a plurality of sensed signals. The device module includes a memory, a controller and a segregation module. The memory stores various health parameters and their respective ranges, various health reports of the user, and basic details of all users. A controller is configured to generate sensed data and the segregation module is configured to segregate the data corresponding to the plurality of health parameters associated with the users. A communication module is configured to enable data communication to and from the intraoral device.

Methods and apparatuses for monitoring either or both the performance of an orthodontic appliance for repositioning a patient's teeth and/or the user compliance in wearing the appliance using a biosensor. The apparatuses described herein may include one or more sensors, including biosensors, electrical sensors, or both, configured to generate sensor data related to user compliance and/or repositioning of the patient's teeth by an orthodontic appliance.

An image of a dental arch comprising a preparation tooth is generated by an image capture device associated with an augmented reality (AR) display. The image of the dental arch is registered to previous image data associated with the dental arch. A visual overlay associated with a dental prosthetic to be placed on the preparation tooth is generated based on the registering of the image of the dental arch to the previous image data associated with the dental arch. The visual overlay is output to the AR display, wherein the visual overlay is superimposed over a view of the preparation tooth on the AR display.

Methods of lowering heart rate during physical activity for a user in need of an increase in their smallest concentric airway cross-sectional area include providing the person with a mandibular repositioning device having a maxillary tooth covering having a driver flange protruding laterally outward on a right and left side proximate a backmost teeth mold and a mandibular tooth covering having a protrusive flange extending cranially therefrom positioned to have a posterior side engaged with the anterior side of each driver flange. The anterior side of each driver flange has a convex curvature, and the posterior side of each protrusive flange has a concave-to-convex curvature from its base toward its most cranial point and a convex portion of the concave-to convex curvature engages the convex curvature of the driver flange in a rest position, and downward movement of the mandibular piece moves the user's mandible forward as well.

For exploiting novel use-cases, in particular sophisticated human-machine interaction, with an intraoral electronic tongue monitoring system designed to be worn by a user on the upper or lower jaw and featuring a support sheet bearing a number of intraoral sensors arranged in an array for recording tongue movement and/or tongue pressure, it is proposed that the system comprises at least one extraoral sensor located outside of the oral cavity delimited by the teeth when the system is in place, in particular such that extraoral and/or intraoral and/or interlabial movements of the tongue and/or lip pressure can be recorded with the system and/or such that the system may be used as an input device controlled through tongue movement using a human-machine-interface provided by the system.

A system for monitoring the cardiopulmonary functioning of a person includes a remote terminal and a sensor module configured to be worn by the person. The sensor module includes at least one physiological sensor configured to sense the following types of physiological information generated by the person: pulse rate, blood flow, and blood pressure; at least one signal processor configured to process signals generated by the at least one physiological sensor; and at least one transmitter responsive to the at least one signal processor that is configured to transmit at least one signal to the at least one remote terminal. The at least one signal processor is configured to focus processing resources on one of the types of physiological information in response to a specified preference by the person.

Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed.
