A method is disclosed where an e-book lending library is provided, the e-book lending library comprising a plurality of e-books. The use of an intermediary transitory material of high-radiation absorbing material creates a symmetrical weld pool which contributes to higher mechanical strength in the weld area. The MEMS device can be used to implement a pressure sensor, microphone, temperature sensor, and a joystick. Also described is a fiber array block having a plurality of V-shaped grooves extending across an outer surface and terminating at an endface. The broken line drawing of an undefined portion of a display screen is for illustrative purposes only and forms no part of the claimed design.
