Abstract: The invention relates to an optoelectronic sensor for detecting objects in a monitored zone that has a light transmitter; a deflection unit for deflecting the transmission light beam without mechanical moving parts or at most with micromechanical moving parts to scan the monitored zone; a light receiver; and a control and evaluation unit that is configured to determine information on the objects by means of the reception signal received by the light receiver. The sensor has at least one reference target that receives at least a portion of the deflected transmission light beam at at least one deflection angle of the deflection unit or returns it to the light receiver in order to generate a reference signal; and the control and evaluation unit is configured to check the operability of the deflection unit by means of the reference signal.

Abstract: 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.

Abstract: A transport system for products comprising a plurality of driverless transport units that move in a travel zone not accessible to persons and that do not have a sensor system for a reliable avoidance of accidents with persons. In this respect, at least one driverless transport unit is configured as an escort vehicle that has at least one sensor for a safe detection of sensor data to safely escort a person in the non-accessible travel zone.

Abstract: The invention relates to a method of increasing accuracy of a global position of a user receiver determined by a navigation system. The global position is corrected based on a position error determined by a mobile reference receiver and transmitted to the user receiver. The invention further relates to a corresponding apparatus.

Abstract: In a method of recognizing and/or tracking objects which correspond to real objects in at least one sensing zone of at least one sensor for electromagnetic radiation on the basis of images of the sensing zone repeatedly sensed by means of the sensor, succeeding images are evaluated in succeeding cycles and a search is made for at least one respective object found in a cycle on the basis of a corresponding image in a correspondingly later image in a later cycle to track the object. At least one part of an earlier image and/or at least one indication with respect to an earlier state of the object or of a real object corresponding to it, which is determined using a corresponding earlier image in the current cycle, is associated with at least one part of a current image determined in the current cycle or with an object recognized in the current cycle during at least one current cycle on the basis of the results of an at least preliminary evaluation of a current image.
