An optical reader system is described herein which has a single mode optical fiber launchreceive system that uses one or more SM optical fibers to interrogate a biosensor and does not use multimode optical fibers to interrogate the biosensor. The bump electrode is connected to a top wiring layer through a plurality of openings in the passivation film underneath the bump electrode, which are filled with a conductive material. The device can have handles adjacent to the front wall of the wedge or can be used without the handles. A toner cohesion enhancement unit is provided for enhancing the degree of toner cohesion of a toner image transferred and reverse transfer is suppressed. The graphics adapter also comprises a network interface operable to receive at least a portion of the graphics image data, the network interface further operable to format the received graphics image data into a plurality of packets for transmission over a communication network. In another embodiment, the recorded activity of the first computer includes navigation through links in the user interface, applying filters to data in the user interface, and accessing data on the user interface.
