An image pickup device 1A is constructed with a photodetecting section 10 having a plurality of pixels; a charge transfer section 12 having 16 segmental charge transfer sections T01 to T16; an AD converting section 15 that converts signals from the charge transfer section 12 to digital data signals; and a digital signal processing section 20. An apparatus for use in this method comprises a pressure member having a skin engaging surface adapted to be pressed against the skin of a patient proximate the site to stimulate the large diameter afferent sensory nerve fibers in the skin proximate the site. This gap allows the block to rest on the lower course of blocks in a stable, level manner by providing a space that can accommodate small amounts of intrusive material such as rubble, dirt, or miscellaneous debris which would otherwise interfere with the stacking of the blocks. After the handover, a MAC layer andor an RLC layer are reconfigured or reset based on functionality supported by the target Node-B. However, an adder adds outputs from the first and second post-processors so that ghosts of the blocks of data are eliminated from an output of the adder. The outcome of this switching method is called fractional lambda switching.
