A method and an apparatus for testing a biometric feature wherein a set value of the biometric feature is stored in a data carrier in the form of one or more data records. For testing the biometric feature, measured values representing an instantaneous value of the biometric feature are first determined and made available in a terminal. The data carrier transmits to the terminal at least a subset of first reference values depending on the data record or data records for the set value. The terminal links data derived from the measured values with the subset of first reference values and transmits the result of the link to the data carrier. The data carrier tests the result of the link and determines therefrom whether the biometric feature is authentic.

Method and device for verifying a biometric characteristic

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.

Method and system for generating a key record

A surgical sliding shaft instrument (,) comprising a guide element (,), which is provided with a carriage (,). It further includes a grip part element (,), which is comprised of a stationary grip part (,), one end of which is provided with a grip trunk (,) pivotably linked to the guide element (,) and also releasably inter-locked with the guide element (,). It further includes a movable grip part (,), which is pivotally connected to the grip trunk (,) and, via a push part (,) extending through a slit in the grip trunk (,), is in operable engagement with the carriage (,). A compression spring (,) tensions or biases the movable grip part (,) in a rest position. An inter-locking element (,) serves for releasable connecting of the grip trunk (,) and guide element (,). The compression spring (,) is integrated in the carriage (,) and pretensions both the carriage (,) as well as the movable grip part (,) in a rest position.
