A method of preserving functionality of an organ. As content is received on a channel, it is placed into the virtual stream with newer content at the start of the stream and progressively aging content migrating farther downstream. for 16 hours in the atmosphere, a barrier layer containing any metal selected from palladium and platinum is farmed at a junction between the copper wire and the electrode pad. One embodiment uses a current sensor for lossless current sensing and emulates the change in inductor current by holding the value of the output of the current sensor at the time that the low side switch turns off and adding an emulated ramp signal until the inductor current reaches zero. In response to an error condition, the server transmits a duplicate of the off-screen surface to the client with instructions to update the client’s on-screen surface using this duplicate surface.
