39 results about "Vestibular system" patented technology

The vestibular system, in vertebrates, is part of the inner ear. In most mammals, the vestibular system is the sensory system that provides the leading contribution to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canals which indicate rotational movements; and the otoliths which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control eye movements, and to the muscles that keep an animal upright and in general control posture. The projections to the former provide the anatomical basis of the vestibulo-ocular reflex, which is required for clear vision; while the projections to the latter provide the anatomical means required to enable an animal to maintain its desired position in space.

Electrode Assembly and Method of Using Same

An electrode assembly for delivering electrical stimulation to a vestibular system of a user or monitoring a physiological parameter of the user. The apparatus includes a body member comprising an electrode support portion and a curved portion extending from the electrode support portion, and an electrode coupled to the electrode support portion. A method of using such an apparatus is also disclosed. The present invention also provides an electrode assembly that includes a body member, an electrode coupled to the body member, a hydrogel element disposed on at least a portion of the electrode. In one embodiment, the hydrogel element includes a hydrogel material and a insulating material disposed on or in the hydrogel material such that the insulating layer disperses energy transmitted by the electrode through the hydrogel material.

Vestibular stimulation apparatus and associated methods of use

A device and associated method for providing vestibular stimulation to an individual includes active elements positioned on or proximate an ear insert. The active elements include but are not limited to at least one electrode, at least one thermometer, and at least one thermoelectric transducer. The device includes a computerized control module regulating the active elements. The device incorporates an ear insert that allows the active elements to engage the individual's ear canal and therefore access the individual's vestibular system. Vestibular stimulation applied to the individual is customized for directly stimulating desired regions of the brain for therapeutic or diagnostic purposes. In a preferred embodiment, the device provides vestibular stimulation sufficient to promote physiological changes in the individual, the changes selected from the group consisting of circadian temperature cycle time shifts, ascorbic acid production, serotonin production, acetylcholine production, histamine production, and heat shock protein production.

A feature extraction and tracking algorithm of nystagmus signals for diagnosis of vestibular system diseases

The invention discloses a nystagmus signal feature extraction and tracking algorithm for diagnosing diseases of a vestibular system, in particular to a video image processing method and a target locating and tracking method, which are accurate in identification and meet clinical requirements. The invention comprises the following steps: 1, reconstructing the opening and closing operation to removethe light spot; 2, the change of the top cap and the bottom cap enhancing the pupil area; 3, positioning the center of pupil; 4, pupil cent tracking; 5, closing the eyes to detect and track the waveform to remove interference. The reconstruction opening operation and the image enhancement method proposed by the invention can effectively preprocess the nystagmus image and accurately extract the pupil of the nystagmus image; the proposed method not only has high recognition accuracy, but also improves the speed of image computation and meets the clinical real-time requirements. In addition, theinvention performs eye-closing detection on nystagmus images and removes nystagmus signal interference, thereby eliminating large deviation and providing reliable basis for subsequent nystagmus signal analysis and research.
