A training apparatus has an input device and a wearable computing device with a bio-signal sensor and a display to provide an interactive virtual reality (“VR”) environment for a user. The bio-signal sensor receives bio-signal data from the user. The user interacts with content that is presented in the VR environment. The user interactions and bio-signal data are scored with a user state score and a performance scored. Feedback is given to the user based on the scores in furtherance of training. The feedback may update the VR environment and may trigger additional VR events to continue training.

The magnetic powder is distributed through an entire volume of the silicone-based elastomeric matrix, and the super-flexible and super-stretchable magnetic skin has a Young modulus of less than 1 MPa and a yield strain greater than 200%.

A head-up display apparatus configured to project an image on a windshield to display a virtual image to a driver includes an image display unit including a light source and a display element and configured to form the image. A display device is configured to project and reflect image light onto the windshield to display the virtual image in front of the windshield. A driver's viewpoint detector is configured to detect a viewpoint of the driver; and a movement mechanism is configured to move a position of the virtual image based on information of the viewpoint of the driver detected by the driver's viewpoint detector. The driver's viewpoint detector detects the viewpoint of the driver by irradiating the face of the driver with the interior light or light of the light source of the image display unit as illumination light at night.

A method of stimulating a lacrimal gland of the user includes monitoring eye condition(s) using the sensor assembly; determining, based on the monitored eye condition(s) and using the microcontroller, if the monitored eye conditions(s) exceed a predetermined threshold; and activating, using the microcontroller and in response to the monitored eye condition(s) exceeding the predetermined threshold, the plurality of electrodes to stimulate the lacrimal gland of the user.

The present disclosure provides methods for determining an etiology of upper and/or lower eyelid puffiness by examining a subject with squinted eyes; and determining if upper and/or lower eyelid puffiness does not improve, improves, partially improves, or worsens, wherein the etiology of the upper and/or lower eyelid puffiness is diagnosed to be anterior to the orbicularis oculi muscle if the puffiness does not improve, wherein the etiology of the upper and/or lower eyelid puffiness is determined to be posterior to the orbicularis oculi muscle if the puffiness improves, wherein the etiology of the upper and/or lower eyelid puffiness is determined to be anterior and posterior to the orbicularis oculi muscle if the puffiness partially improves, or wherein the puffiness is determined to be secondary to hypertrophy of the orbicularis muscle or if the puffiness worsens.

There is provided an electronic device for detecting apnea and a computer-readable storage medium. The electronic device includes: at least one of an electroencephalographic sensor configured to detect electroencephalographic data of a user or a nasal airflow sensor configured to detect nasal airflow data of the user; and a controller communicatively coupled to the at least one of the electroencephalographic sensor or the nasal airflow sensor. The controller is configured to determine a candidate apnea event based on at least the electroencephalographic data or the nasal airflow data.

The invention relates to a device and a method, by which the intraocular pressure in a patient's eye is changed by artificially applying a variable stimulation pressure causing, upon reaching specific intraocular pressure values, the presence of characteristic measurement criteria in the retina of the eye, which allow global and local retinal blood pressure values to be derived from the intraocular pressure value. Based on the retinal blood pressure values, which are determined online or preferably offline, local retinal perfusion pressure values (rPP) can be computed and represented in an image of the retina as a pressure mapping image.

The present disclosure provides electroretinography devices configured to detect biopotential signals from an eye of a subject. In some embodiments, the device is configured to prevent the subject's eyelids from closing over the device when placed in contact with the anterior surface of the subject's eye. In some embodiments, the device has a Young's modulus of no more than about 50 MPa. In some embodiments, the device includes a diffusing or refracting element configured to scatter, focus or diverge incident light. In other embodiments, the device includes a void through which incident light can enter the subject's eye without passing through any portion of the device.
