A biodegradable aliphatic polyester, such as polylactic acid, is mixed with a monomer having allyl and molded into a molding having the crosslinking degree of the biodegradable aliphatic polyester increased. The at least one stimulator is configured to provide stimulus to one or both eyes of the subject. Wavelet analysis, frequency band filtering or other methods may be used to decompose the complex signal into components. One or more acoustic sensors may be fluidly andor mechanically coupled to the engine or other portion of the powertrain system. The components of the kit are meant to be wiped clean after use and placed back into the storage container, thereby allowing for reusability and ease of storage while not in use. According to this configuration, the liquid crystal display device may reduce the size of the memory by calculating modified image signals with respect to the temperature using PQI.
