A thermally conductive silicone composition of the invention comprises: an organopolysiloxane having a viscosity of at least 500 mPa\xb7s at 25\xb0 C. This aid consists of a system of integrated parts allowing an air gap to substantially surround the hearing aid shell and air passages which communicate with the inner ear minimizing occlusion sensations and providing the user with an enhanced natural hearing experience. When the mobile device is loststolen, and another person changes the SIM card, the phone verifies if the SIM card is the same as that of the owner by matching the IMSI numbers of the two. Thereafter, the communication session is established via the communication network. The extracting unit extracts a word from the character string. The anterior surface includes an optical zone and a ramped ridge zone, which is disposed below the optical zone and capable of controlling contact lens position on an eye in primary gaze or translating amount across the eye when the eye changes from gazing at an object at a distance to gazing at an object at an intermediate distance or at a nearby object, or both.
