Abstract: The present invention relates to an augmented reality system (AR system) for teaching a user of an application. The AR system comprises a detection unit that detects a real environment and provides it as environmental data, wherein at least one work unit is arranged in the environment; a communication unit that receives process data from the work unit; a control unit that processes the process data and environmental data, wherein a virtual image can be created based on the process data; and a display unit that displays the real environment and the virtual image in relation to one another to a user. The AR system further comprises an audio output unit that, on the basis of the process data, outputs audio signals for instructing a user, wherein the audio signals are preferably matched to the virtual image.

Abstract: A system and a method using a system for planning a use includes at least one marking, a control and evaluation unit, a database, a display unit, at least one time of flight sensor for a spatial scanning of a real environment, and at least one camera for imaging the real environment. The real environment in a spatial model can be displayed as a virtual environment on the display unit. The marking in the real environment is arranged at a position and has an orientation. The position and the orientation of the marking can be detected at least by the time of flight sensor and the position and orientation of the marking are linked by a virtual sensor model. The virtual sensor model in the spatial model of the virtual environment can be displayed on the display unit at the position and having the orientation of the marking.

Abstract: A method of safeguarding a machine is provided in which a sensor monitors the machine and generates data thereon that are evaluated so that a hazardous situation is recognized and the machine is safeguarded in the event of a hazardous situation, wherein a check is made in a detection capability check whether an estimation of a hazardous situation is possible and the machine is otherwise safeguarded. In this respect, the sensor data are evaluated in a process of machine learning having at least one figure of quality in the detection capability check and an estimation of a hazardous situation is only considered possible with a sufficient figure of quality.

Abstract: An optoelectronic apparatus for securing a source of danger in a spatial zone includes at least one image sensor that works in the infrared spectrum and that can generate range-resolved data of the spatial zone as well as an evaluation unit that is configured for the evaluation of the data for the detection of objects in a three-dimensional protected space within the spatial zone, wherein the source of danger is additionally at least partly secured by a mechanical partition that is at least very largely permeable to visually visible light. To provide a solution that prevents or at least reduces disturbing optical influences from outside the partition, it is proposed that the partition is coated with a layer such that the non-coated layer that is at least partly transparent for the image sensor is visible for the image sensor in a defined manner through the layer and is opaque.
