An apparatus has LCD 13, a photosensitive material holding device that holds photosensitive material 21 on the back of the LCD, first shutter device 20 that can let through and block light from the LCD to the photosensitive material, and second shutter device 19 that blocks infiltration of external light by covering the display surface of the LCD during exposure. A differential pressure is created across a pressure control device downstream from the valve. The TAP may be configured to enable communication between a local application in the network and a remote application in a different network. Updating the target data content may further include initiating workflow to update the target data content. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. In yet another embodiment, a system includes a server, a processor, a horizontal array engine, a vertical array engine, the online medical marketplace, and a network.
