A wearable device includes a wearable device main body, a sensor part configured to contact a skin surface of a user of the wearable device, and measure a bio-signal of the user, and a shock absorber that is interposed between the wearable device main body and the sensor part to mechanically connect the wearable device main body and the sensor part, and that is configured to reduce motion transmission between the wearable device main body and the sensor part to permit the wearable device main body to move independently from the sensor part.

A trauma scene monitoring system includes a medic-worn illumination device, a casualty-worn informatics system, and a remote monitoring station. The illumination device includes a frame with boom-mounted light sources positioned below the wearer's eyes near the zygomatic bones, thus orienting the light sources to project light in the direction of the wearer's view. Also included are audio/video means to capture audio/video information from a scene attended by the medic, and a telemetry unit to transmit that information to the remote monitoring station. The casualty-worn informatics system is integrated within a headband worn by a monitored individual. The informatics system includes sensors to provide the monitored individual's vital statistics and a telemetry unit to transmit data concerning the monitored individual to the remote monitoring station. At the remote monitoring station, receiving and presentation stations provide views of the data concerning the monitored individual and audio/video data from the medic-worn illumination device.

Devices, apparatuses, and systems configured to assist in the location of an ABTT terminus and then to measure the temperature of the ABTT terminus.

Methods, systems, and computer programs encoded on a computer storage medium, for improving EEG measurements by identifying artifacts present in EEG measurements and providing a real-time indication to a user of likely artifacts in EEG measurements are described. EEG measurements of a patient can be obtained by placing a wearable device or EEG cap on a patient's head. Sensors in the cap provide EEG data to a computing device that processes the data to identify one or more artifacts in the EEG data. The artifacts can be identified by conducting one or more operations of determining the signal to noise ratio of the line noise, calculating mutual information between sensor pairs, and applying the p-welch method. Based on the types of artifacts identified, the computing device can output an indicator that provides feedback to the technician performing an EEG test to make adjustments to the test setup.

A device is disclosed comprising: an optical physiological sensor and a further measurement system. The optical physiological sensor comprises a light emitter and a light detector configured to detect the light from the light emitter after it has been attenuated by tissue comprising blood vessels. The optical physiological sensor is configured to determine the value of a physiological parameter from the detected light. The further measurement system is configured to determine when the value of the physiological parameter is likely to be reliable. The further measurement system comprises at least one measurement subsystem, each measurement subsystem employing a different measurement modality that is also different to a measurement modality used to determine the value of the physiological parameter.

Systems and methods are provided to combine multiple stimulation modalities to significantly increase the effectiveness of non-invasive stimulation. Multiple sensor and stimulation devices and modalities can be combined into a single, compact unit that minimizes the need for additional sensors or stimulation devices. The system features several subunits, referred to as sensory and stimulation devices (SSD), that are integrated into a headphone setup. The system is controlled by a centralized controller that communicates with all of the SSDs and with an external computer system that delivers learning material synchronized with the delivery of stimulations and the collection of user responses based on physiological signals.

A metaverse multimedia system based on user brainwaves causes that emotional messages, voice messages and color messages could be captured from the brainwaves of the users. The emotional messages are integrated to the role of the user in the metaverse space. Hence, the role in the metaverse can respond the emotions of the user, while the voice messages and color messages are integrated into the sceneries in the metaverse, which is selected by the user. As a result, the metaverse space completely presents user's states of mind which are captured from the brainwaves of the users. Furthermore the whole sceneries and presentations of the roles in the metaverse space are adjustable with the changes of the users. It can also express user's personalities. Interaction modes between the users and visitors entering into the metaverse space of the user could be analyzed based on the method disclosed in the present invention.

A walking support system includes: an information output device (260); a motion detector (220) which detects a motion of a user; a foot landing position detector (230) which detect a foot landing position of the user; a determiner (240) which determines a recommended foot landing position which is a landing position of the feet suitable for stabilizing motions of a gait of the user on the basis of motions of a gait of the user detected by the motion detector, the foot landing position detected by the foot landing position detector, and dynamics; and an output controller (250) which outputs information indicating the recommended foot landing position determined by the determiner to the information output device.

A technology for a wearable medical device for monitoring medical parameters. Medical measurement data can be received at the wearable medical device from a medical measurement sensor attached to the wearable medical device or a medical measurement sensor in communication with the wearable medical device. A calibration coefficient can be determined for calibrating the wearable medical device based on the medical measurement data. The wearable medical device can be calibrated based on the calibration coefficient.

A system or method for measuring human ocular performance can be implemented using an eye sensor, a head orientation sensor, an electronic circuit and a display that presents one of virtual reality information, augmented reality information, or synthetic computer-generated 3-dimensional information. The device is configured for measuring saccades, pursuit tracking during visual pursuit, nystagmus, vergence, eyelid closure, or focused position of the eyes. The eye sensor comprises a video camera that senses vertical movement and horizontal movement of at least one eye. The head orientation sensor senses pitch and yaw in the range of frequencies between 0.01 Hertz and 15 Hertz. The system uses a Fourier transform to generate a vertical gain signal and a horizontal gain signal.
