Abstract: Among other things, a vestibular prosthesis includes a wearable motion sensing system, the motion sensing system generating a motion signal indicative of a motion thereof, wherein the motion includes rotation about two distinct axes; a signal processor in communication with the motion sensing system, the signal processor being configured to generate an estimate of a tilt of the motion sensing system; and an actuator responsive to the estimate of the tilt made by the signal processor.

Abstract: An apparatus to stimulate the vestibular system of an individual. The apparatus comprises an actuator configured to mechanically stimulate a semicircular canal, and a control module coupled to the actuator that controls the actuator in response to motion information associated with the individual.

Abstract: An apparatus for recording physiological data from an ambulatory subject. The apparatus includes a sensor circuit configured to detect input analog signals including input analog signals resulting from eye movement of the ambulatory subject, and a signal processing circuit, in communication with the sensor circuit, configured to receive the input analog signals and to generate an output digital signal based at least in part on the received input analog signals. The apparatus has physical characteristics suitable for portable use by the ambulatory subject.

Abstract: A method for providing relief from Meniere's disease, includes reversibly disabling vestibular function following detection of an attack of Meniere's disease following detection of an attack of Meniere's disease.

Abstract: An apparatus for stimulating the vestibular system includes an actuator disposed to interact with the vestibular nerve and a controller for causing the actuator to interact with the vestibular nerve. The result of the interaction is that the brain receives a stationary signal.

Abstract: A wearable balance prosthesis provides a information indicative of a wearer's spatial orientation. The balance prosthesis includes an motion sensing system to be worn by the wearer and a signal processor in communication with the motion sensing system. The signal processor provides an orientation signal to an encoder. The encoder generates a feedback signal on the basis of the estimate of the spatial orientation provides that signal to a stimulator coupled to the wearer's nervous system.
