The present disclosure provides a measuring device for biological tissue by using an optical sensor, the device being compact enough to fit in a user's hand and casually usable by the user. The measuring device is provided with: an optical sensor that measures optical data about an object of measurement through a measurement surface in contact with the object of measurement by irradiating the object of measurement with light from a light emitter and causing a light receiver to receive reflected light that is reflected from the object of measurement, the object of measurement being a portion of biological tissue; a temperature sensor that measures the temperature of the optical sensor; and a data processor that processes the optical data on the basis of the temperature of the optical sensor and derives a measurement result pertaining to the object of measurement on the basis of the processed optical data.

A system for sensing true positive impacts may include a sensing device configured for secured coupling to a user. The sensing device may include a sensor configured for sensing accelerations of an impact and for generating a signal based on the impact. The sensing device may also include a control sensor for sensing when the sensing device is in position for sensing. The sensing device may also include a computer-readable storage medium having instructions stored thereon for receiving and capturing the signal from the sensor, and comparing first and second signals from the control sensor to determine if the signal is a true positive signal. The system may also include a processor for processing the instructions to capture the signal, perform the comparing, and identify the signal as a true positive signal. Method of sensing true positive impacts and of workload monitoring are also provided.

A mouthpiece for attachment to an imaging device comprises a tubular body having a first end and a second end, both ends being open, and a band of flexible material attached to the first end of the body. The band comprises an opposing portion opposite the first end of the body. It may also comprise one or more adjacent portions, connected to the first end of the body and parallel to the opposing portion.

Provided is an apparatus for measuring implant osseointegration, and the apparatus for measuring implant osseointegration includes: a vibration generation unit configured to apply multiple vibrations with frequencies in different bands, respectively, to an implant fixture; a vibration sensor configured to measure three-axis vibration information of the implant fixture caused by the vibrations from the vibration generation unit; and a control unit configured to determine the degree of osseointegration based on the measured vibration information.

An optical sensing system includes an optical detector, a rigid support structure for attaching the detector and a coherent light source to a patient and holding those in position, relative to soft tissue, while the coherent light forms a speckle pattern within the tissue in view of the detector. Attaching the detector to the patient via the rigid structure permits hands-free detection of the speckle pattern by the detector. Preferably, the rigid support structure is configured for fitment to teeth of the patient for hands-free positioning of the light source and the detector to image sublingual tissue of the patient and the detector and light source are communicatively coupled to a computer station such that the system is operable for: continuous, hands-free monitoring, by laser speckle imaging, of microcirculation while the patient is in shock, and to manage fluid delivery.

The present disclosure provides generally for a therapeutic oral device for sleep apnea and associated methods for using the device. According to the present disclosure, the device may comprise a hard palate portion, mouth guard portion, and a tongue retainer portion. The hard palate portion may comprise one or more materials. The hard palate portion may also comprise a composite of materials, including but not limited to embedded materials. The mouth guard portion may comprise one or more components that provide stability and maintain the position of the therapeutic oral device within the mouth. The tongue retainer portion may comprise an airway and a predetermined length. A method of use may comprise the utilization of one or more incremental oral devices to overcome a gag reflex. When the oral device is formed from a mold, the mouth guard portion and the hard palate portion may be custom fit to the dimensions of the intended mouth.

A system for preparing a prescription for the use of one or more orthodontal correction devices, such as aligners, which allows for remote interaction and guidance by dental professionals with their patients. The aligner may include a sensor to detect when it is being worn for tracking compliance and determining when the next correction device within the prescription should replace the current correction device. A software application associated with the patient allows them to view and track their progress and to send data to their dental professional, and similarly the dental professional is alerted by the present invention when compliance issues or other issues may arise requiring intervention.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A method of forming an oral device to measure biological variables includes providing a mold configured to impart a contour of an oral retainer sized to extend about a plurality of teeth. The method includes removing the first layer of the retainer from the mold. The method includes attaching at least one sensor to the retainer, the sensor having a profile and defining a boundary edge. The method includes trimming to form a lip of the first layer of material extending beyond the boundary edge of the at least one sensor component. The method includes attaching the first layer of the retainer and at least one sensor component to the mold, forming a second layer of the retainer with the mold, wherein the first layer of retainer retains the mold contour, and wherein the at least one sensor component is disposed between the first and second layer.

The body-worn wireless two-way communication system comprises a non-invasive and non-implanted system which allows for clear wireless two-way communications. This system is generally comprised of a mouthpiece component, relay component, infrastructure communication device, an optional earpiece component, and an optional system control which may interface with the relay component.
