An infrared-ray radiating lamp which is prevented from being mistaken for a tail lamp or a stop lamp by ensuring that not only infrared rays but also visible rays are emanated from a front lens simultaneously. The method employs a fluorescently-labeled phosphorylatable reporter peptide that is capable of being cleaved by a protease only when the peptide is in an unphosphorylated state. A class definition request is received in a first, token driven class loader. The method can also be implemented in a distributed system where the conversion is done at a back-end server and the information is sent to a communication device after a request.
