A device for programming user-defined information into an electronic device is provided. The electrode carrier includes one or more contacts and a hydrophilic segment that swells after insertion in a cochlea and detaches at least in part from the carrier. The coal material decomposition-promoting layers and circular heating layers are isolated from each other, which is helpful for the acquisition of pure coal decomposition gas. The base color of the corolla throat is brilliant greenish yellow and the outside of the corolla tube is moderate olive. The attachment further comprises first and second height-adjustable wheels for attachment to the sides of the platform along with a splash guard disposed on the rear of the platform for protecting the user from overspray.
