A vertically adjustable bed includes a bed frame attached to movable legs powered by a motor. and a melting point of equal to or greater than 280\xb0 C. The techniques are particularly suitable for singulating surface mount devices such as chip scale packages, ball grid arrays, flip chips, lead less packages and the like. The Raman fiber also has at least one adjustable output coupler having a variable reflectivity for controlling the power of the optical radiation propagating from the at least one set of optical gratings at the wavelengths other than the input wavelength. A gate oxide layer is formed over a semiconductive substrate. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into enhanced data packets.
