According to an embodiment, a wearable electronic device may include a motion sensor, an audio sensor, a display, a memory, and a processor electrically connected to the motion sensor, the audio sensor, and the memory. The processor may be configured to obtain motion sensing information via the motion sensor, obtain an audio signal corresponding to the motion sensing information via the audio sensor, identify a tooth-brushing hand motion type corresponding to the motion sensing information, identify an audio signal pattern corresponding to the tooth-brushing hand motion type, and identify, based on the tooth-brushing hand motion type and the audio signal pattern, a tooth-brushing hand motion. Other embodiments may also be possible.

A system includes a memory storing a user profile for a user of the system and machine-readable instructions and a control system including one or more processors configured to execute the machine-readable instructions to receive physiological data associated with the user during a sleep session, determine, based at least in part on the received physiological data, a set of sleep-related parameters for the sleep session, subsequent to the sleep session, select one of the set of sleep-related parameters as a targeted parameter, the selection of the targeted parameter being based at least in part on the stored user profile, the set of sleep-related parameters, or both, and cause information to be communicated to the user via a user device, the information being indicative of the targeted parameter, a recommendation associated with improving the targeted parameter for the user in one or more subsequent sleep sessions, or both.

A sheet-shaped oral appliance is provided that is detachably attached to an oral body device and includes a functional portion with a sensor unit that acquires information in an oral cavity and an energy irradiation unit that radiates energy into the oral cavity, an electrical connection portion, and a wiring portion that connects at least one of the sensor unit and the energy irradiation unit to the electrical connection portion. The functional portion, the connection portion, and the wiring portion are formed by a wiring layer having first and second main surfaces that oppose each other, a first insulating layer arranged on the first main surface and a second insulating layer arranged on the second main surface. Moreover, in the functional portion, a thickness of the first insulating layer is smaller than a thickness of the second insulating layer.

The dental bridge fitting system is a medical device. The dental bridge fitting system is configured for use in measuring the oral surface contours of a patient. The measurements taken by the dental bridge fitting system allow for the fabrication of a dental prosthetic device, such as a bridge, that fits flush on the oral surface that was measured by the dental bridge fitting system. The dental bridge fitting system comprises a mouthpiece, a plurality of capture devices, an image processor, and a master processor. The mouthpiece contains the plurality of capture devices. The plurality of capture devices, the image processor, and the master processor are electrically interconnected.

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 oral body device is provided for attaching to and detaching from an oral appliance that has an electrical connection portion. The device includes a body, and an attachment/detachment operation unit that has an electrical connection conductor and is configured to detachably attach the oral appliance to the body portion by operating application and release of force to the oral appliance. Moreover, the attachment/detachment operation unit fixedly attaches the oral appliance in a state in which the electrical connection portion is electrically connected to the electrical connection conductor by applying a force to the oral appliance, and releases the fixation by releasing the force applied to the oral appliance to detach the oral appliance.

A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide. The color change may be visible from both sides of the detector. In some examples, the respiratory detector may be a biocompatible and conformable sticker for mounting on a person's face or an oxygen delivery device.

A medical tool includes, a deflectable distal end, at least a pull wire, and a deflection assembly. The at least pull wire having a first end coupled to the distal end of the medical tool and configured to be moved for deflecting the distal end. The deflection assembly is coupled to a second end of at least the pull wire and is configured to control a deflection of the distal end. The deflection assembly includes a first gear having a first rotation axis, and a second gear, having a second rotation axis and including a jagged surface for integrating with the first gear. The jagged surface is slanted relative to the second rotation axis, and when the first gear rotates, the second gear is configured to be rotated by the first gear, to move along the second rotation axis and to deflect the distal end by moving the pull wire.

Improved assessment of brain injuries, and improved brain injury management, is achieved using a combination of impact-related data derived from instrumented mouthguard devices, human function performance testing, and biomarkers derived from biological fluid (such as saliva and/or blood). The human function performance testing may include brain function performance testing, and/or other forms of human function performance testing. This involves combining a data-driven understanding of a head impact event (based on data collected via an instrumented mouthguard device) with a data-driven understanding of human function performance following that head impact event. The biomarkers may include salivary mRNA and/or ncRNA, and/or blood proteins (for example via a FDA-approved Brain Trauma Indicator test).

A system and method is provided for monitoring a biological substance in a bodily orifice. The system includes a wearable device configured to be worn in a bodily orifice. A biosensor is carried by the wearable device and is constructed and arranged to obtain raw data regarding a biological substance in the orifice. The biosensor includes a processor circuit to provide processed data from the raw data, and a transmitter to wirelessly transmit the processed data to a second device.
