The present invention provides a peer-to-peer data communication system and method that allows a first handset and a second handset to engage in data communications over a wireless communication network. The transformer further includes a second waveguide comprising a second core, a second cladding and an end directly coupled to an end of the first waveguide. A target region of interest is determined based on the determined camera motion direction. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member.
