A hollow fiber membrane fluid transport device’s method of manufacture is disclosed wherein the fibers are comprised of Polytetrafluoroethylene, and the potting materials are comprised of fluoropolymer based materials. The talc is characterized in that it contains Al2O3 in an amount of less than 1% relative to the weight of said talc. In a preferred embodiment, a split word line design is used for each single-port memory cell, to facilitate dual-port memory access while minimizing the need for IC layout space. The weld parameters are based upon a difference between an initial tool shape and a desired tool shape. A sensor can sense an external condition such as light or touch to control the electronic timer. A distributed controller activates and deactivates the LED drivers so that different subsets of LEDs within the LED package are driven sequentially.
