A LED drive system for controlling an off-chip power supply enables the power supply function to be located \u2018off-chip\u2019\u2014i. In particular, a sealable multi-layer opaque film that is moisture permeable and water resistant. The packet parser processes a TCP segment within an arriving network frame, where the packet parser performs one or more speculative CRC checks according to an upper layer protocol, and where the one or more speculative CRC checks are performed concurrent with arrival of the network frame. Another embodiment provides a gate electrode structure with thin inner spacers and partially recessed outer spacers. The guards are adaptable to a wide variety of folding knife styles. A gear motor can detect a position of the movable display section.
