An external automatic defibrillator including an attachment device that can be externally attached and carried by a patient, an identification device for detecting an abnormal event in the cardiac activity, which can be treated by an electric shock, as well as a defibrillator allowing to exert a shock upon the patient after having detected the abnormal event. In order to ensure reliable functioning over a longer period of time, the identification device is configured so that the identification device can detect an abnormal event in an interval of not more than 90 seconds or one minute.

External automatic defibrillator

An intraocular lens with an optical lens part, which has a central lens area and at least one further annular lens area surrounding the central lens area, the central lens area and the at least one annular lens area forming at least one common focus and the annular lens area having concentric annular zones, in which the difference in pathlength between adjacent zones is an integral multiple of n&equals;2 or more of the design wavelength.

Intraocular lens having a central lens area, an annular lens area, and a meridian section

The invention concerns a structure arrangement that includes surface regions having one or more structures having an optical-diffraction effect, in particular for visually identifiable, optical security elements for value-bearing documents, for example banknotes, credit cards, passes or check documents, or other items to be safeguarded; in order to make it more difficult to forge and in particular copy such a structure arrangement it is proposed in accordance with the invention that the structure arrangement is such that for the production of given items of optical information in given viewing directions in one or more of the surface regions (,) of the structure arrangement there are provided sub-regions (,) with a structure (,) that is identical except for the structural parameter of optical depth and that the optical depth of the structure (,) is constant over the extent of a sub-region (,) but is different from the optical depth of the structure (,) of another sub-region (,).

Optically diffractive structure

In a method of three-dimensionally patterning the surface of a printing or embossing cylinder the surface of the cylinder is irradiated with exposure beams in accordance with the desired pattern and then the surface is patterned in accordance with the exposure. To achieve particularly fine structuring of the cylinder surface, the radiation dots serving to expose the surface are produced by means of beams which, before impinging on the surface of the cylinder, to form fine structures, are modified in accordance with the desired pattern by means of a beam-forming element. The pattern of the respective radiation dot which is impinged on to the cylinder surface is moved synchronously with respect to the movement of the cylinder surface in accordance with the rotary movement thereof.
