A system and method for determining the operational state of a logic device having a plurality of shadow registers, each associated with one of a plurality of functional registers. A plurality of protrusions protrude vertically and downwardly from the pressing frame. A client computer and a server computer are connected to a computer network, and the data storage device is connected to the server computer via the host interface port. The dual-chain and roller clutch pumping system is appropriate for gasolineelectric hybrid vehicles where pumping may be necessary when the engine is off and limited packaging space is available in the transmission housing. The device may include a textured layer disposed between the second n-type layer and the second contact or formed on a surface of a growth substrate opposite the device layers.
