A multi-rate speech codec supports a plurality of encoding bit rate modes by adaptively selecting encoding bit rate modes to match communication channel restrictions. Reuse of the device is not permitted, if the use monitoring element indicates a prior use. A method for making the lamination is also disclosed. The web is next transferred to a hot reel, which maintains the temperature of the molten polymer above its melting point and thereby facilitates wicking of the molten polymer into the web. And each of the high-sensitivity pixel and the low-sensitivity element comprises a first pixel separation layer located on the light illumination surface side in the semiconductor substrate to separate the pixels from each other.
