Abstract: A shoe electrode comprising an electrode, a skin adhesive for attaching the electrode to the skin, an electrically conductive heel pad, and a conductive pathway between the electrode and the heel pad. A removable adhesive is used to attach the heel pad to the heel of a shoe and in one embodiment, the electrode, heel pad and conductive pathway are formed as a single piece of conductive vinyl film.

Abstract: An earphone assembly is disclosed that includes an annular baffle having an outer surface and an inner surface as well as an interior wall and an exterior wall. The interior wall defines a central chamber. A transparent, flexible lid is attached to the baffle along the outer surface, completely covering the central chamber and forming an acoustic seal with the baffle. The lid has an inner face and an outer face. The flexibility of the earphone is improved by creating hinges in the lid and by providing cuts, or other discontinuities, in the baffle. For example, a radial cut may be disposed in the annular baffle. Further, a circumferential cut may also (or alternatively) be disposed in the baffle, extending from the inner surface and disposed between the exterior wall and the interior wall. At least one hinge may be disposed on the flexible lid. To improve the attachment of the earphone to the patient's head, tabs are mounted to the exterior wall.
