A system includes a focus optic configured to converge an electromagnetic radiation (EMR) beam to a focal region located along an optical axis. The system also includes a detector configured to detect a signal radiation emanating from a predetermined location along the optical axis. The system additionally includes a controller configured to adjust a parameter of the EMR beam based in part on the signal radiation detected by the detector. The system also includes a window located a predetermined depth away from the focal region, between the focal region and the focus optic along the optical axis, wherein the window is configured to make contact with a surface of a tissue.

Technology is adapted to facilitate user-specific calibration of instrumented mouthguard devices, including calibration methods for instrumented mouthguard devices. For example, this includes processes by which instrumented mouthguards, which include components such as accelerometer modules that enable monitoring of head movements of a mouthguard wearer, are calibrated for use by specific individuals. While some embodiments will be described herein with particular reference to those applications, it will be appreciated that the present disclosure is not limited to such a field of use, and is applicable in broader contexts.

A scanner system for capturing a three-dimensional model of an object includes a laser and a camera to capture two-dimensional images of the object. The system also includes a tube mounted to a rail, a central processor configured to receive data collected from the laser and the camera and an actuation mechanism configured to move the tube along the rail. The tube is configured to move generally along a travel axis of the rail. The tube includes open first and second tube ends. The laser and camera are mounted inside the tube between the first and second tube ends. The first tube end includes a first continuous ring and the second tube end includes a second continuous ring. A channel extends through the tube between the first and second rings positioned adjacent the rail in an assembled configuration.

The present disclosure provides systems and methods for remote dental monitoring. In an aspect, the present disclosure provides a computer-implemented method for remote dental monitoring. The method may comprise (a) providing a patient portal for one or more patients to remotely communicate with a caregiver, wherein the patient portal comprises a graphical user interface that is configured to aid the one or more patients in capturing one or more dental scans, wherein the one or more dental scans comprise (i) one or more intraoral videos and (ii) a plurality of images derived from the one or more intraoral videos; and (b) providing the one or more dental scans to the caregiver for an assessment of a dental condition based on the one or more dental scans.

Methods, devices, and systems related to determining biometric data using an array of infrared (IR) illuminators are described. In an example, a method can include projecting a number of IR dots on a user using a dot projector and an array of IR illuminators, capturing an IR image of the number of IR dots using an IR camera, comparing a number of pixels of the captured IR image to a number of corresponding pixels of a baseline IR image using a processing resource, and determining biometric data of the user at least partially based on comparing the captured IR image to the baseline IR image using the processing resource.

Some of the embodiments of the present disclosure are directed to a dental measurement method comprising, for example, measuring an orientation of a dental measurement device which includes a user interface, and displaying information on said user interface based on said orientation.

A monitoring device for monitoring the fluid balance of an animal or human body. The device includes a body weight sensor for continuously or periodically weighing the body, a fluid delivery device for providing a controllable supply of fluid to the body, a urine output sensor for determining the urine output of the body, a processor. The processor is adapted for determining a total fluid outtake of the body and a fluid outtake due to perspiration and respiration by taking a signal provided by the body weight sensor and a signal provided by the urine output sensor into account, and providing a control signal to the fluid delivery device to regulate a volume, flow velocity or flow rate of the fluid delivered to the body, so as to maintain a predetermined fluid balance in the body.

This invention is a wearable device or system for optical analysis of breast tissue which be embodied in a “smart bra” or an insert which is placed into the cup of a conventional bra. This device or system has light emitters which transmit light into breast tissue and light receivers which receive the light after it has been transmitted through the breast tissue. It also has expandable chambers which gently compress a breast to reduce light diffusion and improve optical scanning of breast tissue.

A system and method for human motion detection and tracking are disclosed. In one embodiment, a smart device having an optical sensing instrument monitors a stage. Memory is accessible to a processor and communicatively coupled to the optical sensing instrument. The system captures an image frame from the optical sensing instrument. The image frame is then converted into a designated image frame format, which is provided to a pose estimator. A two-dimensional dataset is received from the pose estimator. The system then converts, using inverse kinematics, the two-dimensional dataset into a three-dimensional dataset, which includes time-independent static joint positions, and then calculates, using the three-dimensional dataset, the position of each of the respective plurality of body parts in the image frame.

A method for postural independent location of targets in diagnostic images acquired by multimodal acquisitions, compensating for deformation of soft tissues due to changing posture, includes generating a transition of a digital image of the inside of a target region from a first to a second position by correlating the position of markers placed on the external surface of the target region in a digital image of the inside of the target region and in a digital representation of the external surface of the target region acquired by optically scanning the external surface; and at a later time registering the diagnostic image of the inside of the target region, transitioned into the second position, with a diagnostic image of the same target region acquired with the target region in the second position by matching a second representation of the external surface of the target region in the second position without markers with the diagnostic image of the inside of the target region transitioned into the second position.
