Abstract: It is proposed to combine the advantages of PIN-based protection systems and biometry-based protection systems and avoid the disadvantages of the respective systems by generating the PIN biometrically uniquely. For this purpose it is provided that only characteristic data that are uniquely reproducible are derived from the determined biometric raw data. On the basis of these uniquely reproducible characteristic data a key record is then generated that either constitutes the PIN code or is used to generate the PIN code. The PIN code is thus always reproducible uniquely on the basis of the biometric data. The user need no longer remember the PIN code, and the PIN code cannot be passed on to third parties.

Abstract: The invention provides for a method of forming discrete solder portions (16) on respective contact pads (10) whereby a strip of solder paste (12) is formed over a plurality of said pads (10). The strip (12) is formed with portions of reduced width (14) which are located over the spaces (22) between adjacent pads (10). The paste is melted and the surface tension at the portions of reduced width (14) causes the movement of solder towards the pads (10) and the separation of the strip (12) into discrete solder portions (16).

Abstract: A printed circuit board assembly which includes a two-dimensional array of connectors to provide significantly higher data transfer rates than typical one-dimensional connectors, without sacrificing board space. The assembly preferably includes a plurality of connection pads on each printed circuit board. An anisotropically conducting material is placed between the connection pads and the boards pressed together.
