Abstract: The present invention relates to an avalanche protection device that includes an avalanche protection backpack with at least one inflatable buoyant airbag and a breathing system with a breathing housing. The breathing housing connects a one-way inhalation valve to an inhalation tube, and at least one intake port, and at least one ambient air suction zone. It also connects a one-way exhalation valve to an exhalation tube and a CO2 exhalation region. A mouthpiece is provided on the breathing housing, which is able to be automatically pulled tightly onto the mouth of an avalanche victim by means of a facial airbag, by actuating a trigger handle. The invention additionally relates to a method for using such an avalanche protection device.

Abstract: A method automatically parameterizes error detection of an image inspection system by a computer. The method includes digitizing a reference image in order to determine desired values and subdividing the reference image into homogeneous image regions with few edges, and inhomogeneous image regions with strongly structured image areas and many edges. Lower tolerance values for the homogeneous image regions, and higher tolerance values for the inhomogeneous image regions of the digitized reference image are determined by statistical image analyses. The determined tolerances are assigned to their respective desired values in dependence on a position of the desired values in homogeneous or inhomogeneous image regions. An inspection sensitivity is calculated from desired values and their respective tolerances. The parameters of the image inspection system are set with the aid of the inspection sensitivity configuration of the image inspection system using the parameters.

Abstract: The invention relates to a system (1) for controlling an electrolytic reaction in a reaction medium, with the system (1) comprising a primary energy storage (10), an intermediate storage (30) and a control unit (50). The control unit of the system is adapted for transferring electrical energy from the primary energy storage into the intermediate storage, monitoring the state of charge of the intermediate storage, establishing an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is larger than or equal to a first threshold value, and interrupting an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is smaller than or equal to a second threshold value.
