A network of controllers for controlling and monitoring associated assay testing systems coupled to a remote monitoring unit for monitoring and controlling the controllers andor the assay testing systems is disclosed. The door body is attached to one end of a wire rope, and an auxiliary force generating means is attached to the other end thereof. The digital media assets can be grouped into collections of digital media assets. The electrode is positioned adjacent to a workpiece and a power supply is connected to the electrode and the workpiece to charge a capacitor until discharge takes place between the electrode protrusions and the surface of the workpiece, to electro-discharge-machine the workpiece to replicate the pattern of electrode protrusions into the workpiece.
