Patent DE-3918618-A1 (DE)
Inventor: ENGELHARDT RALF DIPL PHYS
IPC: B23K26/00
Filed: 1989-06-07
Abstract: In a process for treating a material with a laser (1), with identification of the material to be treated, the laser light is directed onto the material by means of a laser optical system (3) and the light re-emitted by the material is directed onto a detector (8) which measures its intensity. The laser output or energy is controlled by an evaluation circuit (9) connected downstream. To control the laser and/or an optical switch (2) arranged in the path of the laser output beam, the rate of variation of the intensity of the light incident on the detector is evaluated in relation to the rate of variation of the laser pulse. In the time that elapses between the beginning of the laser pulse and the occurrence of dielectric rupture, the intensity of the light re-emitted by the material is measured in at least one predetermined spectral range and used to identify the material on which the laser pulse impinges.

Patent DE-4014109-A1 (DE)
Inventor: PREIDEL WALTER DIPL CHEM DR
IPC: A61B5/1473
Filed: 1990-05-02
Abstract: A process is disclosed for electrochemically determining the oxygen concentration, in particular of bodily fluids, by means of an oxygen sensor having a sensor electrode. An exact oxygen concentration can be obtained by impressing upon the sensor electrode a potential profile with several potential stages. The first potential stage covers a range between -0,5 and -1,2 V (first measuring potential), the second potential stage a range between -0,5 and 1,3 V (second measuring potential) and the third potential stage lies at about 0 V, in relation to an Ag/AgCl reference electrode. There is a potential difference equal to or higher than 50 mV between both measuring potentials and the length of stay at each of both measuring potentials lasts between 10 and 50 ms (measurement period). The current flowing at both measuring potentials is determined and integrated in time, the integration starting 5 to 30 ms after the beginning of the measurement period and lasting for 5 to 10 ms. The oxygen concentration is determined by calculating the difference between both integrals.
