A system and/or method for diagnosing a neurologic condition. The system comprises a wearable head orientation sensor, a wearable eye imaging module, and a display with a visual target. The head orientation sensor is responsive to pitch or yaw head orientation information. The eye imaging module is configured for imaging a characteristic of the retina, sclera, cornea, limbus, or pupil to determine an eye position or eye movement. An electronic circuit in the system determines an ocular parameter measurement in response to the head orientation sensor and the eye imaging module. The neurologic condition is diagnosed in response to the ocular parameter measurement.

A transducer array including a conductive layer and a conductive gel layer is described. The conductive layer has one or more electrode element. The one or more electrode element is configured to receive electrical signals from an electric field generator producing an electric signal as a Tumor Treating Field. The conductive gel layer overlaps the one or more electrode element of the conductive layer. The conductive gel layer has a first region and a second region. The first region has a first resistivity and the second region having a second resistivity with the first resistivity being different from the second resistivity.

Some systems, devices and methods detailed herein provide a system for use in determining metrics of a subject. The system can provide, as an output, a function-metric value determined based on a defined relationship between physiological measures and a chronological age.

Arrangements described herein relate to a headset system and a method to manufacturing the headset system, the headset system including a headset configured to lay on top of a surface and to support a head of a subject when the subject is in a supine position or a reclined position, at least one probe adjustment mechanism, and a probe coupled to the at least one probe adjustment mechanism and configured to emit acoustic energy.

A method, intended for the evaluation of the quality of at least one periodic or quasi-periodic physiological signal, which includes the steps of: segmenting the physiological signal temporally into a plurality of signal segments; for each given signal segment, determining a distance representative of a shape difference between the given signal segment and at least one signal segment temporally offset relative to the given signal segment; and determining a quality index of the given signal segment according to the distance determined for the given signal segment.

A system for in-vivo monitoring of intracranial pressure is provided. The system includes a probe and a controller. The probe includes optical emitters and optical detectors. The optical detectors detect light emitted by the optical emitters generate signals representative of the detected light. The controller includes memory and processor. The controller connects to the probe to energize the optical emitters and receiving signals from the optical detectors. The system may include modelling, extraction, and pressure prediction modules. The modelling module can relate intracranial pressure to features of an optical signal representative of a degree to which light input into a subject's skull is absorbed by the subject's brain. The extraction module can extract signal features from a signal derived from the optical signals output by the detectors. The pressure prediction module can input the signal features into the modelling module and output an indication of intracranial pressure.

A system for concussion assessment, comprises a head mounted display and a remote AI host. The head mounted display is disposed for displaying at least one test image to a user and obtain a plurality of physiological data from the user. The remote AI host communicates with the head mounted display through a first network connection, so as to obtain a concussion assessment result according to the plurality of physiological data.

Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. A first analysis, having relatively lower computational processing demand than at least a second analysis, processes signals from a subject to determine a first estimate of a propensity for the subject to have a neurological event. If the first estimate meets a set of specified criteria, a second analysis is performed to determine a second estimate of the propensity for the subject to have a neurological event.

A system and method for maintaining a patient's body temperature during and after surgical exposure is provided. A surgical, insulative cap both aids in maintaining the patient's core body temperature at an euthermic range and further incorporates a graphic display panel for providing a remote caregiver informational interface. Vital signs sensors may therefor communicate, either directly or remotely, to said informational interface and allow, access to vital signs information to the caregiver in a convenient manner that does not require diversion of attention from the patient in order to monitor.

In one instance, a process for predicting and using emotions of a user in a virtual reality environment includes applying a plurality of physiological sensors to a user. The process further includes receiving physiological sensor signals from the physiological sensors and preparing the physiological sensor signals for further processing by removing at least some of the noise and artifacts and doing data augmentation. The process also includes producing an emotion-predictive signal by utilizing an emotion database. The emotion database has been developed based on empirical data from physiological sensors with known emotional states. The method also includes delivering the emotion-predictive signal to a virtual-reality system or other computer-implemented system. Other methods and systems are presented.
