Patent DE-19722094-A1 (DE)
Title: Data reduction or compression method for monitoring installations
Inventor: AUERBACH DAG
IPC: G08B15/00
Filed: 1997-05-27
Abstract: The method involves controlling the data reduction or compression by alarm probability. The signals of coupled sensors cause a preselection and storage of the data volume on a respective channel, which is subjected to a reduction and/or compression in a not necessarily on-line, but multi-repeatable process of after-valuation and/or alarm probability. The necessary process information is derived from the sensor signal protocol and/or the data recorded during the preselection. Preferably the memory location of the preselected data is vacated after the evaluation and/or alarm probability compression which is typically carried out by computers.

Patent DE-19822684-A1 (DE)
Inventor: KAUFHOLD JUERGEN
IPC: B29C71/04
Filed: 1998-05-20
Abstract: The invention relates to a method for producing gradient index refraction index profiles in polymer optical fibres (1). Said method is based on the fact that ionising radiation causes an increase in the refraction index of PMMA, for example. Polymer optical fibres, preforms or fibre core preforms are therefore guided past a source of radiation (5, 12, 13) at a predetermined speed and irradiated with ionising radiation of a predetermined wavelength and in a predetermined dose, before being tempered for a set period of time. By controlling the spatial distribution of the ionising radiation using mirrors (3), lenses (11) or systems of apertures (14), it is possible to produce a uniform radial gradient index refraction index profile over the total length of the fibre. As a result, the polymer fibre as an optical waveguide has essentially better transmission properties for optical signals.

An Independent claim is also included for a method of conveying foil.
