Abstract: The present disclosure generally relates to auditory nerve stimulation to create the perception of sound in the brain of a subject such as an animal or human being. In one form, a system includes an implantable electrode array including a plurality of spaced apart micro-needles. The system also includes a first electrical lead electrically coupled to and extending from the implantable electrode array, and an auditory signal device configured to produce one or more electrical signals representative of communications received from an external processor. An interposer is configured to electrically couple the implantable electrode array and the auditory signal device in an arrangement where one or more electrical signals produced by the auditory signal device may be transmitted through the first electrical lead to the implantable electrode array. Various novel stimulation strategies can be employed, such as place modulated stimulation signals.

Abstract: The present disclosure relates to filters. Teachings thereof may be embodied in a filter assembly, e.g., a filter assembly for filtering output currents from a voltage converter. For example, a filter assembly may include: a current conductor with a curved profile; a first ferrite body; a second ferrite body; and a recess with a curved profile defined in at least one of the first ferrite body and the second ferrite body. The first ferrite body and the second ferrite body may combine to surround the current conductor and the current conductor may extend along the recess.

Abstract: A web processing roll comprising at least one cavity. The cavity of the roll is at least partially filled with a mixture of a liquid and at least one mixing partner that is insoluble in the liquid. Solid particles, preferably a granular solid, or another liquid constitute the mixing partner.
