A method of determining one or more characteristic values for an environment automatically trafficable by vehicles comprises the steps: providing a spatially resolving, electronically usable representation of the environment; providing parameters that describe properties of vehicles and of the traffic in the environment; simulating the traffic in the environment with reference to the electronically usable representation of the environment and with reference to the parameters provided; in the simulation, detecting and counting events of interest, detecting and counting events of interest, determining the characteristic values with reference to the counter result, and outputting and/or storing the characteristic value.

Determining one or more characteristic values and simulating traffic for an autonomously trafficable environment

An optoelectronic safety sensor () is set forth for the contactless measurement of paths and/or speeds of the safety sensor () or of a first object connected in a fixed position to the safety sensor () with respect to a second object () moved relatively to the first object, which form a potential source of danger, wherein the safety sensor () has a light source (), a light receiver () with a plurality of light reception elements and has an evaluation unit (), with the evaluation unit () being configured to determine by means of an optical correlation process and/or by evaluation of the optical flow the path and/or the speed from at least two images of a surface structure () of the second object () taken sequentially by the light receiver (). In this respect, the evaluation unit () is further configured to evaluate the quality of the determined path and/or of the determined speed, and a safety output () is provided via which the evaluation signal () can output a shutdown signal or brake signal to secure the danger source when a required quality is not reached.

Safety system for contactless measurement of paths and/or speeds

The invention relates to an apparatus and a method for the detection of an object moving in the monitored region of a camera, wherein measured values are compared with reference values and an object detection reaction is triggered when the measured value deviates in a predetermined manner from the reference value. In this respect, both the measured values and the reference values are derived from differences which exist between at least two different image regions.

Apparatus and a method for the detection of objects

A protective device for securing to a component movable along a track and for the monitoring of a protected zone moving with the component includes a light transmitter for the radiation of a divergent transmitted light beam into a spatial zone containing the protected zone, a light receiver for the reception of at least some of the light of the transmitted light beam of the light transmitter radiated into the spatial zone and for the emitting of corresponding received signals, and a restriction device which is arranged in the direction of a transmitted light path after a section of the transmitted light path which contains the protected zone and by means of which the transmitted light beam can be restricted to a less divergent received light beam defining the width of the protected zone in at least one direction.
