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.

This invention is a wearable system for monitoring a person's food consumption comprising a motion sensor worn on a person's wrist, a camera worn on the person's ear or housed in the person's eyewear, and a data processor which analyzes data from the motion sensor. The camera is automatically triggered to take pictures of food when analysis of data from the motion sensor indicates that the person is eating.

The present invention provides an ultrasound oral cavity tomography system, comprising a chin-supporting structure, a plurality of U-shaped ultrasound detectors, and an ultrasound examination unit. The chin-supporting structure is provided with a recess. Each of the U-shaped ultrasound detectors comprises a plurality of ultrasound probes arranged in a U-shaped array. The ultrasound examination unit is connected to the U-shaped ultrasound detectors and configured to form three-dimensional images of an oral cavity based on signals received by the U-shaped ultrasound detectors.

An adjustable sensor mount and associated headset that may include a band with circumaural earcups and cushions may be configured to position a sensor forward of the tragus of a user. The headset may include a speaker, a microphone, and a controller. The mount may include a base configured for sliding engagement with the cushion and a sensor holder secured to the base and configured to receive the sensor. The base may be made of a generally C-shaped resilient plastic or metal material. The holder may be pivotably secured and/or slide relative to the base. The holder may include a support arm that slides and/or pivots relative to the base and receives a housing adapted to secure the sensor. The housing may slide and/or rotate relative to the support arm, and may have an elastomeric covering. Sensor signals may be processed to provide a gating signal for the microphone.

In this invention, a high-accuracy jaw motion tracking system and method using the same are disclosed. The jaw motion tracking system of the invention mainly comprises an eyewear facebow static positioning device, a lower jaw dynamic tracking device and a stereo-vision charge-coupled device (CCD) and can provide information regarding the locations and relative movement of lower and upper jaws. The eyewear facebow static positioning device has several passive and active reflective markers. The lower jaw dynamic tracking device equips with a plural of lightweight light emitting devices. Using OpenCV-based self-developed algorithm and post-iterative compensator, the disclosed system can record the dynamical jaw movement with a high accuracy. The disclosed jaw motion tracking system and related method have minimal occlusal disturbance and provide smooth motion-tracking performance. The disclosed system can be used in clinical dentistry.

The present discourse provides a tongue manifestation detecting device. The tongue manifestation detecting device comprises: an image acquisition component configured to acquire a surface image of a tongue; a temperature acquisition component configured to acquire parameters characterized by the temperature of the tongue; and a brightness temperature image generation component configured to generate a brightness temperature image of the tongue based on the parameters characterized by the temperature of the tongue acquired by the temperature acquisition component.

An intra-oral scanning device and system are augmented to provide an active delete (or filter) tool. The tool automatically detects and deletes unwanted items and artifacts capturing as the scan is being done. The technique provides a better user experience by automatically removing items the deletion of which that may otherwise be time-consuming, frustrating, or impossible for the user to delete any other way.

The invention provides a sensor assembly embeddable within an oral appliance comprising a sensing means; and a data processing means coupled to the sensing means for processing data obtained by the sensing means; wherein the sensing means and the data processing means are sealed within a deformable layer.

A method of using AR for dentistry and orthodontics is provided. An image of a dental arch is received, the image having been generated by an image capture device associated with an augmented reality (AR) display. A processing device registers the image to previous image data associated with the dental arch, compares one or more areas of the dental arch from the image to one or more corresponding areas of the dental arch from the previous image data, determines a position of an area of interest on the dental arch based on the comparing, generates a visual overlay comprising an indication of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.
