The invention described herein provides a method and apparatus for document processing that efficiently separates and interrelates single modalities, such as text, handwriting, and images. The outward facing surfaces of the soundboard and head-plate are provided with a decorative appearance such as by etching or sanding a pattern thereon. The handheld device can communicate with a server to download the customer information onto the handheld device and to upload from the handheld device current customer information data obtained from a customers sales visit to a server. Constructing magnetic system as two permanent magnets which are aligned at their analogous poles, and placing optical fiber in a throughhole, the throughhole being formed by the facing grooves made in said analogous poles of permanent magnets, ensure optimization of the design of optical fiber probe, the body of said optical fiber probe having limited dimensions. A plurality of support flanges are fastened to each interior member and corresponding side member for additional structural support.
