This invention provides supplying a model that will together with software and a controller, separately selectively cycle up or cycle down color stations in accordance with their need for a particular imaging run. Use of such a system improves safety by preventing contact with exposed wires. The order within the queue, as well as the order in which the queued requests are serviced, may, in some embodiments, be optimized. More preferably, the amount is sufficient to provide partial or complete pain relief within 25 minutes. A electrochemical transistor device is also provided, wherein an ion isolative material is provided between a solidified electrolyte and an organic material having the ability to electrochemically altering its redox state, such that a transistor channel of said transistor is defined thereby.
