Abstract: Apparatus for protection of the ear and ear canal, and related methods of use and operation. In one embodiment, the apparatus includes a selectively actuated valve which permits a varying or modulated size of aperture to be created by the wearer while the apparatus is in use, so as to accommodate varying functions, such as complete occlusion (e.g., for use in swimming or other aquatic activities such that water can be completely excluded) or partial occlusion (e.g., such that sounds can be heard by the wearer, whether in air or under water). In one implementation, the apparatus is retained within the ear canal of the wearer by virtue of the apparatus' shape and coordination with one or more natural features or contours of the anatomy in the ear region, without having to be inserted more than superficially into the outer portion of the ear canal.

Abstract: Selectively controllable apparatus for insertion into an ear canal, and related methods of use and operation for behavioral control. In one embodiment, the apparatus includes a body configured for insertion into an ear canal. In one variant, the body includes one or more thermal mechanisms which enable selective increase or decrease of temperature of at least portions of the ear canal so as to implement behavioral control of the user, such as to mitigate cravings for food, alcohol, narcotics, or other potentially deleterious substances. In one variant, a mild nausea or pre-nausea condition is created within the user according to a time-temperature profile so as to induce the aforementioned behavioral modification.
