Disclosed are methods and systems for informing a user about hearing aid feedback noise including, for example, receiving, through one or more microphones, an acoustic signal sample, analyzing the acoustic signal sample to determine whether feedback noise is present in the acoustic signal sample, and displaying to the user an indication of whether feedback noise is present in the acoustic signal sample.

Hearing aid feedback noise alarms

The invention relates to systems and methods for estimating a response of at least a part of a physiological system to a first deterministic stimulus signal. The methods include separating a measured first signal into a plurality of segments, each segment representing a response of the physiological system to a corresponding portion of the first stimulus signal and generating a template signal representing the plurality of segments. The methods further include calculating a measure of similarity of each segment in the plurality of segments to the template signal to provide a set of scalar quantities, and determining a metric representing a characteristic of the response of at least a part of the physiological system to the first stimulus signal.

Signal processing in physiological noise

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.

Vestibular stimulator

An apparatus to reduce the sensitivity of the vestibular system to stimulation. The apparatus comprises a plugging device configured to constrain the movement of endolymph fluid within a semicircular canal, and a control module coupled to the plugging device that causes the plugging device to maintain a set actuated position.

Vestibular canal plug

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.

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.

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.

Balance prosthesis

A multi-layer equine saddle pad. The saddle pad is made of non-woven polypropylene material that is both durable and has high-moisture performance. The multiple layers are attached by stitching or bonding together along their centerlines such that the attachment terminates short of either end of the non-woven material layers. The multiple-layer pads are maintained free from any permanent attachments along their edges.

Multi-layer saddle pad

An animal feeder for providing feed to animals includes a plurality of side and end walls defining an interior chamber. A perforated plate defines a bottom wall of the chamber and is moveable therein. A grate defines a top wall of the chamber and allows access to feed material contained in the chamber. A spring mechanism biases the plate toward the grate such that feed material located within the chamber is continuously provided to an animal feeding at the level of the grate.
