A dental diagnostic assembly for diagnosing dental health includes a handle that can be gripped by a dentist. A sensing probe is coupled to the handle and the sensing probe has a curved end which can be positioned against a tooth in a patient's mouth. A diagnostic unit is in remote communicates a diagnostic pulse to the sensing probe to transmit the diagnostic pulse into the tooth. The diagnostic unit analyzes the resistance to the diagnostic pulse to determine the health of the tooth. Moreover, the diagnostic unit includes a display for displaying numbers indicating the value of the magnitude of resistance to visually communicate the health of the tooth to the dentist.

An oral appliance includes: 1) a body defining a channel to accommodate an upper dentition; and 2) a motion sensor. The body includes a front portion defining a recess, and the motion sensor is affixed to the front portion.

Disclosed is an apparatus for recording respiratory rate of a subject. The apparatus comprises a first component to be arranged on the subject and away from nostrils of the subject, the first component comprises a battery, optionally electronics for the sensor, and electronics for transmitting respiration rate data; and a second component for being arranged in an area of the nose of the subject, the second component comprising at least one sensor for recording respiratory rate. Disclosed is also a method for recording respiratory rate of a subject with such an apparatus. The method comprises arranging the second component in an area of the nose of the subject; arranging the first component on the subject and no further than 30 centimeters from the second component; recording respiratory rate data with the second component, and sending the respiratory rate data to the first component; and sending the respiratory rate data from the first component to a monitor or a hub.

There is provided a device for measuring fatigue of a person, the device comprising a frame configured to be worn within the mouth of the person, a microphone mounted within the frame and configured to measure sound data, and a cavity located within the frame and adjacent to the microphone, wherein the cavity does not communicate with the environment surrounding the frame. There is also provided a computer-implemented method for determining a fatigue metric representing a level of physical fatigue of a person

A respiratory status examination apparatus and method, and a sleep disorder control device and method are proposed. The apparatus may include at least one image capturing unit that is movably arranged to adjust a distance with respect to a subject and configured to obtain a thermal image by photographing the subject. The apparatus may also include a motion sensor unit configured to detect a motion of the subject to generate motion information, and a temperature information extracting unit configured to specify at least one examination region from the thermal image obtained by the image capturing unit and extract temperature information from the examination region. The apparatus may further include a respiratory status examining unit configured to determine a respiratory status of the subject based on the temperature information extracted by the temperature information extracting unit and the motion information generated by the motion sensor unit.

A device for the drying of tooth or bone surfaces includes a radiation source for irradiating the tooth or bone surface to be dried, a temperature sensor and/or a humidity sensor.

A device for determining measurement values describing the function of the lungs or the respiratory system of a patient includes a mouthpiece including a tube for introducing respiratory air and for sucking in air, and a gas measurement space. At least one of the following gas sensors is arranged in the gas measurement space: nitrogen monoxide sensor, carbon dioxide sensor, oxygen sensor, carbon monoxide sensor, multi-gas sensor, sensor for volatile organic compounds, alkane sensor, infrared sensor, fiber optic sensor, resistance sensor, and semiconductor sensor. The gas measurement chamber is separated by a closable opening into a first gas measurement chamber and a second gas measurement chamber, the second gas measurement chamber being closed or closable. The closable opening opens a flow path from the first gas measurement chamber into the second gas measurement chamber. A gas sensor is arranged in the second gas measurement chamber.

Devices and methods for monitoring physiologic parameters are described where an airway device, in one embodiment, may comprise a mouthpiece section and an opening section defining one or more airway lumens therethrough with a first sensor in fluid communication with the one or more airway lumens and a second sensor positioned upon a hand-piece for contact against a portion of the user. The first sensor may be configured to detect an airway pressure when a user inhales or exhales through the one or more airway lumens, and the second sensor may be configured to detect a physiological signal from the user. Additionally, a controller may be in communication with the first and second sensors where the controller is programmed to correlate pressure oscillations in the airway pressure with heartbeats.

Disclosed is a glucose measuring apparatus including a pressure measurer having an elastic part or a pressure sensor, that measures a pressure applied to an object, a film that comprises a first optical waveguide configured to be close to the object, a near infrared ray (NIR) irradiator that irradiates an NIR to the first optical waveguide if the measured pressure is greater than or equal to a preset value, an NIR receiver that receives an attenuated total reflection NIR (ATR-NIR) from the first optical waveguide, and an analyzer that measures a blood glucose level based on the ATR-NIR, wherein the film is an independent module that can be combined with and separated from the glucose measuring apparatus.
