Abstract: The invention relates to a method, to a device, and to a computer-readable storage medium with instructions for monitoring the movement of a transportation device. In one embodiment, first, information about the trajectory of the transportation device is received by a mobile device. The trajectory is then displayed on a display unit of the mobile device in the form of an augmented reality representation. In response thereto, an input of the user of the mobile device for influencing the trajectory is detected. Finally, information is transmitted to the transportation device on the basis of the input of the user.

Abstract: Process for preparing primary amines from aldehydes by mixing an aldehyde with a diluent, where in the case of an alcohol or of water as diluent the mixing temperature is at most 5.degree. C. to prevent the formation of the hemiacetal or the aldehyde hydrate, and bringing the mixture into contact with a mixture of ammonia, hydrogen and hydrogenation catalyst, whereby the formation of an imine is prevented, at temperatures of from 60.degree. to 180.degree. C. and pressures of from 20 to 60 bar, at least 15 mol of ammonia being used per mol of aldehyde group, and also an apparatus for carrying out the process.
