An electronic imager capable of performing selectable signal processing functions on measured pixel signals includes fixed digital logic circuitry. The threshold determining device comprises an individual threshold evaluation unit, an individual threshold distribution evaluation unit, and an overall threshold determination unit. When the fuel cell system is to be stopped, the reforming reaction of the reformer and the electrochemical reaction of the fuel cell are stopped and a portion of unreformed fuel is fed to the reformer and the fuel cell stack. At least one process writes data to at least one buffer, including to the trigger address thereof. The article has a radiation element that radiates a transmission signal supplied from the feeder circuit of the electromagnetic-coupling module via electromagnetic coupling and that supplies a received reception signal to the feeder circuit via the electromagnetic coupling. The lens is received by and secures to the mirror case at the light opening and preferably is recessed into the bottom surface of the mirror case.
