摘要： A sensor module for a sensor is provided that has a sensor unit having a detection direction and a detection height as well as a module housing having at least a first outer wall for arranging at a planar base surface, whereby then an orientation and a height position of the module housing and thus the detection direction and detection height of the sensor unit are fixed. In this respect, the first outer wall has a three-dimensional contour here that is adapted to the individual detection direction and/or detection height of the sensor unit and tolerances of the sensor unit in the detection direction and/or detection height is/are compensated by the three-dimensional contour on an arrangement of the first outer wall at a planar base surface.

摘要： A method for modeling a sensor\ for measuring a distance in a virtual test environment include: defining a simulation model, wherein the simulation model includes a virtual sensor and the virtual test environment, and a virtual transmission signal sent by the virtual sensor is simulated in the virtual test environment; it is determined whether the virtual transmission signal impacts a virtual object at a point of impact in the virtual test environment; in the event of a positive determination, a distance of the virtual transmission signal covered by the virtual sensor up to the point of impact is calculated in the virtual test environment; and at least one output value of the virtual sensor is determined, wherein the determination of the output value takes place based on at least one parameter of the simulation model, wherein the parameter and/or the output value is/are modeled by a probabilistic distribution.

摘要： A method is provided using a safety system. The safety system has an electronic access system for a safety zone for objects, at least one radio transponder and at least one radio station to recognize the radio transponder, at least one control and evaluation unit that is connected to the radio station for evaluating the read radio transponder information, and at least one spatially bounded access zone having an access station. The safety zone is only accessible via the access zone so that the access zone can be passed through by the object before reaching the safety zone and after leaving the safety zone, with the access station being actuated when an object passes through the access zone. Permitted objects have the radio transponder, with the radio transponder having an identification whereby the object can be identified. The permitted objects having the radio transponder can pass through the access zone.
