Abstract: This invention relates to a mobile crane with at least one memory unit in which limit curves or limit values are stored for various crane parameters, which should not be exceeded, or only by issuing an alarm signal, to ensure safety during operation of the crane, and with means for ensuring crane safety, which are configured such that they monitor the individual limit values of the various parameters for exceedance, and with means for checking the current position of the extendable and retractable props which serve to support the mobile crane. In accordance with the invention, means are provided, which in dependence on the actual position of the supporting cylinders reached determine the tilting edge of the mobile crane as limit value. Furthermore, means are provided, which in dependence on the individual parameters of the mobile crane and the suspended load determine whether the operating condition of the mobile crane lies within this limit value.

Abstract: The present invention relates to a method for measuring phase boundaries of a material during the machining of a workpiece (12) with a machining beam, more preferably with a laser beam, and a device that is embodied in such a way as to carry out the method. According to said method, during the machining, a machining region (13) containing the impact point of the machining beam (1) on the workpiece (12) is illuminated at least approximately coaxially to the machining beam (1) by means of additional optical radiation (2). Radiation (3) reflected by the machining region (13) is detected, parallel to an incidence direction of the optical radiation (2) or at small angle thereto, by means of an optical detector with local resolution, in order to obtain an optical reflection pattern of the machining region (13).

Abstract: The invention relates to measuring the concentration of analytes with the aid of an oxidase in an immersion sensor situated in a fluid or in a matrix containing fluid. Oxygen diffuses into the enzyme layer from within, from a gas-filled space connected to the atmosphere and/or to an oxygen reservoir. This enables oxygen saturation of the oxidase in a low-oxygen or oxygen-free medium and/or at high analyte concentrations. The analyte diffuses into the enzyme layer in a channel or a number of channels which contain(s) water and limit(s) diffusion, wherein the channel/channels on the surface of the sensor is/are filled with a protein-impermeable, hydrophilic matrix. By increasing the channel cross-section on the surface of the sensor and/or by connecting the channel/channels to a protein-impermeable, porous, hydrophilic layer on the surface of the sensor, the effect of outer deposits on the diffusion resistance of the analyte is reduced.

Abstract: In a method for cutting structural components to be joined by laser radiation that is guided by a computer-controlled manipulation system provided with a nominal path for each structural component corresponding to a joining line that is curved as a result of at least one of the structural components being three-dimensionally shaped, the structural component surfaces of the structural components including the joining line are determined measuring technologically. Based on measuring results, the nominal path corresponding to a penetration line of the structural components to be joined is calculated. A marking is formed on a first one of the structural component surfaces. When performing the cut on the structural component surface provided with the marking, the resulting cutting gap and the marking are determining measuring technologically. When a deviation of the cutting gap from the nominal path is detected, the manipulation system is controlled to correct the deviation.
