Systems and techniques that facilitate background monitoring of eye health are provided. In various embodiments, a system can comprise a sensor component of a device. In various aspects, the sensor component can detect one or more physical characteristics associated with an entity. In various embodiments, the system can further comprise a diagnostic component of the device. In various instances, the diagnostic component can estimate in a background of the device a health condition of an eye of the entity based on the one or more physical characteristics. In various cases, estimating the health condition in the background of the device can facilitate real-time monitoring of the eye health of the entity without interrupting the entity's normal use of the device.

A perfusion device is for evaluating the risk of thrombotic and hemorrhagic diseases linked to blood coagulation processes. In particular, a cartridge is for conducting a dynamic ex-vivo evaluation method of the coagulation process in a subjects blood sample, including at least one perfusion chamber, a well for loading the blood sample and reagents, an inclined ascending microchannel connecting the well to a first end of the perfusion chamber and an inclined descending microchannel placed at a second end. Preferably at least one perfusion chamber includes two half-channels of different width, placed in series or in parallel, or the cartridge includes at least two perfusion chambers placed in parallel. At least two of the perfusion chambers have a different width.

In a method for determining a type of characteristic eye movement of the eyes of a patient, the patient is provided with an optokinetic stimulus for the characteristic eye movement, a medical image of the brain of a patient also including the eyes of the patient is generated. An amount of a displacement of an optic nerve of the patient may be determined based on the medical image and a type of a characteristic eye movement may be determined based on the velocity of eye movement for the determined amount of displacement of the optic nerve. In a method for training an artificial intelligence based algorithm for determining an amount of a displacement of an optic nerve of a patient, the algorithm may be trained based on at least one medical image.

Systems and methods for performing a Horizontal Gaze Nystagmus (HGN) test. An HGN test device having a harness configured to be worn by a subject, a moveable stimulus controlled by a computing device, and a recording device for recording the eyes of the subject during the administration of the HGN test. More specifically, the HGN device has a movable armature or an arm with a stimulus there attached which follows a track. The recording may be stored in the computing device or transmitted to a remote system for storage.

Devices for determining the likelihood that a user of a primary monitoring device (PMD) has developed a medical condition, generally comprising sensors coupled to the PMD, wherein the PMD detects changes to sensor readings over time, and wherein the changes indicate a change in the likelihood that a user of the PMD has developed a medical condition. In some embodiments, motion sensors are operably coupled to the PMD, and the PMD monitors and saves data relating to characteristics of motion detected, which are used to determine whether there has been a change in a likelihood that a user is undergoing a medical event. In further embodiments, the PMD comprises cameras, and the PMD monitors and saves data relating to movement of a user's eyes, which is utilized to determine whether there has been a change to a likelihood that the user is currently undergoing a medical event.

A device for measuring eye movement in a human subject, the device having a housing, at least one stimulator mounted to the housing, and a sensor. The at least one stimulator is configured to provide stimulus to one or both eyes of the subject. The sensor is configured to collect information related to movement of one or both eyes of the subject. The device also includes a user interface that is configured to control the at least one stimulator and display information collected by the camera.

A device, system, and method for operating a nystagmus testing device is disclosed. The device comprising a camera configured to face a test subject to capture eye movements of the test subject, a start button configured to start a nystagmus routine, a front display positioned to face the test subject configured to display a visual stimulus, a rear display positioned to face a test administrator configured to display a visual tracker, and a controller configured to control movements of the visual stimulus and the visual tracker on the front and rear display, respectively, and generate data of the nystagmus routine.

System for generating, emitting and interpreting a composite stream and associated method. The invention relates to a system making it possible to generate, transmit, interpret and exploit a composite data stream. The invention relates more precisely to a method for emitting a composite data stream advantageously through a wireless communication network, and a method for interpreting a composite data stream. Said methods are respectively implemented by the processing unit of an electronic object and by the processing unit of an electronic device.

A portable VOG device is disclosed that will facilitate the effective and efficient screening for TBI in military personnel in forward deployed military settings or remote locations using minimally trained staff. This includes the establishment of a protocol that will provide cost effective pre-screening of military personnel prior to deployment to establish a baseline of brain function prior to possible future injury. The efficiency of the device will promote subsequent follow-up screening to assess the effectiveness of prescribed TBI treatment. Further protocols for diagnosis and rehabilitation applications using the same virtual reality portable device will allow more advanced usage for clinicians providing ongoing evaluation and treatment.

Disclosed is an interactive gaze analysis kit for the early diagnosis of neurodegenerative pathologies essentially composed of a video camera with framing on the eyes of the patient and a screen both connected to a calculation unit through which the user is shown images specifically designed for being able to observe the presence of micronystagmus, the reaction times following an optical stimulations and measure the light sensitivity threshold, through which the diagnosis can be found. Since the test is particularly sensitive to the level of brightness to which the patient is subjected, it is necessary to have the presence of a dark tunnel through which the patient can look at the screen, an infrared, visible spectrum or infrared and visible spectrum lighting system, an image analysis software and input-output peripheral devices for allowing the interaction both with the doctor and with the patient. Other related embodiments are described.
