A system and method for managing healthcare information is disclosed. The light-transmissive cover includes a first light-transmissive member located in an area, among areas to the side of the nitride semiconductor light-emitting chip, and in a direction perpendicular to a polarization direction of the polarized light, and a second light-transmissive member located in an area above the nitride semiconductor light-emitting chip. If the values are equal, said signal transmitted comprises said residual data and said associated coding information items. Normal exception processing by the data processor can be resumed after debugging, or exception processing by the data processor can be aborted to allow the normal execution of instructions by the data processor to resume.
