A gaming device that includes a plurality of elements or symbols which are each in one or more of a plurality of element groups or sets. Under one aspect of the invention, the optical chip features one or more large mode field size waveguides, one or more low minimum bending radius waveguides to interconnect the large mode field size waveguides, and one or more optical functions integrated within or connected to the large mode field size waveguides. The router applies one or more input interface filters associated with the input interface that received the packet. In some embodiments, one or more of the components may act as a server for other components in the network. Next, a proper imaging position H0, at which the reference position of the photographic photosensitive material should be imaged on the reading device, is fetched. The lower clamping unit including a rotary pad with a swivel ball in restricted surfaces of a clamper and a locator of a lower clamping unit to deal with an angle difference of restricted cross sections of the door.
