Abstract: Methods and devices for managing output devices in a vehicle are disclosed. Data is obtained representing a sensed position of the first vehicle and a sensed feature in a proximity of the first vehicle. A first probability density function (PDF) is defined based on the obtained data, representing likelihood of a future position of the first vehicle. A second PDF is defined based on the obtained data, representing likelihood related to a proxemic risk presented by the sensed feature. A risk metric is computed representing a likelihood of the proxemic risk to the first vehicle based on an overlap between the first PDF and the second PDF. A useable number of information bits is determined, based on the risk metric. An application is controlled to provide output, via output device(s) of the first vehicle, within the useable number of information bits.

Abstract: It is an object of the invention to specify an electrically heatable reactor for hydrogen cyanide production and the production of other nitriles that enables a differentiated temperature profile and requires no more than inexpensive standard components. The core of the inventive apparatus (0) is a chamber (1) made of gas-permeable, thermally insulating material that constitutes the actual reaction space. Electrical heating elements (5) project into the chamber (1), such that the chamber (1) can be heated from the inside by the heating elements (5). The electrical terminals of the heating elements are outside the reaction space but within the surrounding shell. Unlike in the industrially implemented BMA process, the heat is thus not transported into the reaction space from the outside, but rather generated in the reaction space. The heat is generated by conversion of electrical energy by means of the heating elements (5) by the principle of resistance heating.
