Abstract: A vestibular stimulation system and method that includes a housing, a power supply disposed in the housing, an electrode assembly adapted to be coupled to the housing, and a controller disposed in the housing and operatively coupled to the power supply. The controller controls the delivery of energy from the power supply to the electrode assembly. An input element is also disposed on an exterior surface of the housing. The input element is manually manipulated to control the operation of the vestibular stimulation system. A display disposed on an exterior surface of the housing provides visual information regarding the operation of the vestibular stimulation system. A mounting assembly is coupled to the housing to mount the housing on such a user.

Abstract: The present disclosure describes a system configured to stimulate a vestibular system of a user while the user is in a sleeping position. The system comprises a housing; a power supply; an electrode assembly; a controller that controls stimulation of the vestibular system through delivery of energy from the power supply to the electrode assembly; an input element configured to control operation of the system; an auditory output device that provides auditory output to the user, wherein the auditory output is synchronized with the stimulation of the vestibular system to enhance an effect of the stimulation; a mounting assembly for mounting the housing on the user; and a sensor adapted to generate an output signal related to a physiological parameter of the user, wherein the controller controls the electrode assembly to cease delivery of the energy responsive to the output signal indicating that the user is leaving the sleeping position.

Abstract: Apparatus for the non-invasive and specific activation of the vestibular system in a patient. Preferred embodiments of the present invention allow for the placement of a stimulating electrode in the ear canal while providing a firm and comfortable coupling with the patient. The stimulating electrode is a deformable material that contacts the skin in the ear canal. A stimulating device operates in cooperation with the stimulating electrode to generate a stimulation waveform for the stimulation of the vestibular system.

Abstract: A system and method of detecting possible sleepwalking episodes that include generating one or more signals indicative of the movement of an individual while sleeping, determining whether the movement signals indicate a possible sleepwalking episode, causing one or more motion based alert signals to be emitted if the movement signals do indicate a possible episode, monitoring a proximity of the individual to a position within a sleeping environment, and causing one or more proximity based alert signals to be emitted when the individual is determined to be at least a certain distance away from the position.

Abstract: Two-wire signal transmitter and method in which a very low-level Alternating Circuit (AC) input signal sensed at a remote circuit at a first end of a signal path is added to a low-level Direct Current (DC) bias signal provided by a local circuit that is located at a second end of the signal path. In a preferred embodiment, the remote circuit is electrically coupled to and powered by the local circuit through a two-wire path interconnection, typically a shielded twisted-pair cable. The DC bias signal has sufficient level to overcome minimum ratings of electrical contacts, thereby to pass the sensed very low-level AC input signal reliably through the poor electrical contacts that are used, for instance, for connecting electronic circuits that run the length of a railway train.
