One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to an optical fiber. A partial region of the digital x-ray detector is used to generate an x-ray image of the sample. In order for the light to fully couple between the fibers it is imperative that this walk-off be accounted for. A secondary region is laterally spaced from the primary region. Further, the operations can include pairing the mobile device with the secondary content controller after determining that the primary wagering game content is in the state that would permit the secondary wagering. The method includes the steps of mixing the first component and second component together to form a mixture, compounding the mixture, and pelletizing the compounded mixture to form pellets of a biodegradable polymer composition.
