An apparatus for effecting change in at least a portion of a selected site of a collagen containing tissue that is at least partially adjacent to a fluid medium. A pair of opposing, elongated first and second walls extend outwardly from the base first surface in adjacent, spaced-apart relationship. The substrate is thinned using a layer transfer technique or chemicalmechanical processing. When the rootfs and the application program are recorded in a storage system of the embedded device, the method downloads the rootfs and the application program from a storage system of the embedded device, and burns the rootfs and the application program to a register of the flash memory. A level of activity may be one of: active, inactive, hibernating and standby.
