As part of an examination device, an input or output optical coupler device for transmitting photons between an optical source or detector and an examined body part includes an array of optical fibers with end portions freely protruding as cantilevers from a support. Differential expression of GA2ox genes correlated with flower development, seed germination, tiller growth and other developmental processes. The pilot signals are extracted from the received signal matrix. Through the process, the administrator TV obtains information of wireless devices sought to be registered in the home network, enabling the administrator TV to capture the network structure or topology, which may be used for further applications, without implementing dedicated protocols such as UPnP to collect the information. In addition, the first and the second optical input signals output from the waveguide are combined.
