Abstract: An apparatus includes a first element and a second element configured to be repeatedly mechanically coupled to and decoupled from one another, a first seal between the first element and the second element, and a second seal between the first element and the second element. The first seal is configured to inhibit moisture ingress from an environment surrounding the first and second elements to a first region enclosed at least partially by the first seal and the second seal is configured to inhibit moisture ingress from the first region to a second region enclosed at least partially by the second seal. One of the first and second seals includes two first surfaces of the first and second elements in contact with one another, and another one of the first and second seals includes a second surface and a resiliently bendable protrusion of the first and second elements in contact with one another.

Abstract: An apparatus includes a first portion and a second portion configured to be repeatedly mechanically coupled to and decoupled from the first portion. The first portion includes at least three protrusions in electrical communication with first circuitry. Each of the at least three protrusions is displaced from and extends substantially parallel to a center axis and at least two of the at least three protrusions are displaced from the center axis by distances that are substantially different from one another. The second portion includes at least three receptacles in electrical communication with second circuitry. Each of the at least three receptacles includes two tines configured to be in mechanical and electrical communication with a corresponding protrusion of the at least three protrusions upon insertion of the corresponding protrusion into a region at least partially bounded by the two tines.

Abstract: An external device of a prosthesis, including an electronics component, which can be a sound processor of a hearing prosthesis, and a power component, which can be a battery, the power component being removably attached to the electronics component, wherein the BTE device is configured with electrostatic discharge protection between the electronics component and the power component.
