A method and structures are provided for implementing individual integrated circuit chip attach in a three dimensional stack. The apparatus comprises an input terminal for receiving the serial data stream of channel words, a serial-parallel converter unit means for serial-to-parallel conversion of the serial datastream into a parallel datastream of n-bit intermediate channel words. The second dynamic proxy object thus allows for a single implementation for repetitive methods, while allowing special cases to be handled independently. By regulating the flow of liquid, the check valve can hinder spilling of liquid contained within the water filter during removal or replacement of the water filter. The flexible sealing strip has a stem that mounts on a leg wall of the carrier, a first arm that laps onto the edge of the headliner panel and a second arm that laps onto the track. is stored on disk and is transferred to flash memory within the HDD upon power-down of the primary operating system.
