A web page has a player for playing media objects, a sequencer which displays a play list that defines an order in which media objects are played by the player, and a media access area for containing a plurality of graphical icons. The controller includes a programming interface, located within a system load-store memory map of each OSD by which the OSDs request the controller to perform IO operations with remote FC devices. The device may further comprise a cell delivery device for delivering cells into the porous scaffold. The regulating valve has a regulating piston configured to be adjusted by a solenoid.
