Augmented reality systems and methods for user health analysis. Methods for user health analysis may include collecting data for an initial prediction model and continuing to collect additional data based on one or more data criteria. The methods may further include updating the initial prediction model based on the additional data to produce a revised prediction model or causing an intervention to occur based on the additional data. The data may be collected by a display system including one or more sensors configured to collect user-specific data and a display device configured to present virtual content to a user. The display device may be configured to output light with variable wavefront divergence.

An anatomical manometry catheter system, comprising a plurality of balloons on the distal end and being configured to be inflatable and/or deflatable. The system includes a connector assembly coaxially aligned with the catheter assembly, the connector assembly being connectable to the proximal end of the catheter. The connector assembly may have a connector interface connected to the proximal end of the catheter. The connector assembly may include a manifold comprising a plurality of channels configured to deliver the pressure transmission medium therethrough toward a respective catheter lumen for inflating one or more balloons. The connector assembly may include a charging mechanism fluidly coupled to the catheter that facilitates inflating each balloon of the plurality of balloons by a common actuating mechanism so as to simultaneously charge each balloon of the plurality of balloons.

A soft-tissue-injury diagnostic system for diagnosing soft tissue injury within a patient includes a set of hand-held inclinometers configured and arranged for measuring angles formed between a first inclinometer disposed in proximity to a patient joint and a second inclinometer disposed distal to the joint during controlled patient movements of the joint. A plurality of measuring electrodes are coupleable in proximity to the patient's spine along the body portion that moves along the joint. The measuring electrodes are configured and arranged for measuring action potentials along patient muscle groups during the controlled patient movements of the joint and transmitting the measured action potentials to a dynamic surface electromyograph (“sEMG”) module. A hub receives and processes data from the inclinometers and the dynamic sEMG module. A visual display is configured and arranged for receiving and displaying the processed data.

An exercise feedback system determines muscle fatigue measurements using physiological data generated by a sensor-equipped athletic garment. The muscle fatigue measurement is determined by analyzing the frequency spread of the physiological data. The exercise feedback system may customize exercise programs, determine risks of injury, or generate biofeedback for presentation on graphical user interfaces using the muscle fatigue measurements. The exercise feedback system accesses pre-determined muscle fatigue measurement models that define criteria for the aforementioned features. For instance, if an athlete is becoming fatigued and exercising with improper form based on a muscle fatigue measurement, the exercise feedback system modifies the athlete's exercise program to help target and improve the athlete's weaknesses as well as to prevent injury.

A system and method are provided that employ a monitoring device to monitor at least one patient physiological response to a change in temperature of the patient (e.g. pursuant to induced hypothermia therapy), wherein a monitoring signal is provided by the monitoring device. In turn, an output (e.g. a visual and/or auditory output) may be provided to a user indicative of at least one measure of patient response to the change in temperature. Alternatively or additionally, a processor may be provided to process the monitoring signal and provide an output employable by medical personnel to control a patient shivering response to the patient temperature change. Such information may comprise information regarding one or more anti-shivering medicament(s), e.g. corresponding dosage and/or frequency information for use by medical personnel in the administration of the anti-shivering medicament. In one approach, a motion sensor may be selectively attached to a patient's chin to provide a wireless monitoring signal to a transceiver. In turn, the transceiver may provide the monitoring signal to the processor on an ongoing basis to output information useful in the administration of an anti-shivering medicament, including updated information that takes into account a patient's response to a prior administration of one or more medicaments in conjunction with the subsequent administration of an anti-shivering medicament.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

A system and method for controlling a device to alleviate sleep apnea comprises determining whether a user of the device is asleep by a microcontroller operatively connected to the device. Using a sensor operatively connected to the microcontroller, it is determined whether a breathing anomaly of the user is detected while the user is asleep. An electromagnet operatively connected to the device generates an electromagnetic field to widen an airway of the user in response to detecting the breathing anomaly while the user is asleep.

Examples of force sensors that may be incorporated into a number of devices or other objects are disclosed. In one example, a sensor comprises a substrate comprising a first electrode and a second electrode, the first electrode and the second electrode being spaced by an insulating gap, and a compliant material with plural conductive pathways disposed over the gap and contacting the first electrode and the second electrode such that a resistance of an electrical path passing through the compliant material between the first electrode and the second electrode changes in response to force of the compliant material against one or more of the first electrode and the second electrode.
