In a spread illuminating apparatus comprising a spot-like light source, and a light conductive plate, the light conductive plate is shaped into a pentagon which has two sides thereof substantially parallel to each other. The inner stents and outer stent are separated andor encapsulated by a protein-based material of a protein matrix andor a set biocoacervate, each one or more biocompatible proteins and one or more biocompatible solvents. Each mobile data communication device receives data items from the wireless network and includes a device configuration stored in a memory location on the mobile data communication device. The switch may be an electric switch disposed in a hand held device, such as a barcode scanner in some embodiments. The etching stop layer is then electroplated with copper. The first end wall has a sloped wall extending angularly between the side walls, and two input terminals are mounted on the sloped wall.
