An optical device for surface enhanced Raman spectroscopy includes a substrate, and at least one antenna established thereon. As an example, the communication system may include a master device. Further embodiments include methods for querying and receiving event data from manageable resources on a host device. The connection mechanism further comprises an upper cap, a first fitting piece, a fitting set and a spring. The data connector may conform to a standard for connecting peripheral devices, such as the Universal Serial Bus standard or the Institute of Electrical and Electronics Engineers 1394 standard.
