A method and system whereby new devices may be introduced for use with a particular device driver without necessitating a change to the device driver binary is disclosed. The first surface of the first die can be coupled to the second surface of the second die. The heat sink further includes a membrane associated with the coolant-carrying channel. In a third step, the change in position of the dynamic background from the first frame to the second frame is calculated. The compounds according to the present invention comprise an antibody binding terminus moiety covalently bonded to a cell binding terminus through a linker and optionally, a connector molecule.
