Abstract: A system and methods are used to enable hearing device calibration using auditory filters. The system and methods are used to reduce processing time for estimating auditory filters for new hearing device users and can be performed by the user without the aid of an audiologist. The system and methods use a database of notched-noise test results of other users to create a prior distribution of possible auditory filter parameters. The prior distribution is used to minimize the number of notched-noise test performed, thereby reducing the amount of calibration time.

Abstract: The cartridge comprises an anti-friction bearing positioned between rotating seals. At one end of the bearing the outer race makes rotary sealing contact with rim of an annular sealing disk of softer material than the bearing race. At the other end of the bearing the outer race is urged axially against the sealing disk by a resilient member. The other end of that member presses against a second annular sealing disk having a flange around its central opening which forms a rotary seal with a shaft extended through the cartridge. The bearing cartridge during assembly is partially filled with lubricant and rotation of the bearing causes lubricant to be thrown against the inner surface of the bearing and the cartridge by centrifugal force and circulated thereby through the load-carrying area of the bearing in the direction of the pressure applied by the resilient member and back through the remainder of the bearing.

Abstract: A bearing cartridge assembly or conveyor rolls or the like comprises a bearing structure, a fluid lubricant containing particles of magnetizable material disposed within the bearing, and permanent magnet lubricating means disposed adjacent the bearing elements but separate therefrom so as to establish magnetic flux paths between the bearing elements through the fluid lubricant, whereby the lubricant is distributed uniformly over the bearing surfaces by magnetic attraction.
