Plural repetitive patterns 61 are formed on a transparent substrate 62 in the unit of a chip 65. In particular, putative palmitoyl protein thioesterase and encoding nucleic acids are provided. Moreover, an electric power socket is installed on the front case of the socket body, and a combination part is set up on one side of the power socket. The measured data set is compared to the plurality of reference data sets and based on the comparison, the dopant density of the doped region of the substrate is determined. A protocol having initialization, transmit and receive portions is described to facilitate configuration operations, such as reads and writes of configuration registers, for such a link.
