Abstract: The invention relates to a method and an apparatus for validating a continuously measuring, non-invasive blood pressure measuring system equipped with a plethysmographic system capable of obtaining—in a measuring phase—a plethysmographic signal v(t) at an extremity, having a control mechanism to which the signal v(t) from the plethysmographic system is fed, which varies the contact pressure pC(t) at the extremity via a control value u(t), and having an evaluation unit which continuously determines the arterial blood pressure curve pA(t) based on the resulting contact pressure pC(t). According to the invention, the blood pressure measuring system has a coupling interface via which—in a validation or test phase—a signal derived from a previously recorded blood pressure curve can be input into the blood pressure measuring system.

Abstract: The deformation element (1) of a rail-borne vehicle is disposed in the region of at least one deformation zone located on the end side of the vehicle and comprises at least one tubular hollow space, wherein a structure is attached in a replaceable manner in the rail-borne vehicle and is formed of two metal sheets (2a, 2b), of which at least one is designed as a profiled metal sheet (2a′, 2b′) and which are connected together on mutually facing cross-pieces (3a, 3b) which lie against each other thus forming hollow boxes (4a, 4b) extending in parallel with respect to each other.
