Abstract: A circuit arrangement includes a preprocessing circuit configured to obtain context information related to a user location, a learning circuit configured to determine a predicted user movement based on context information related to a user location to obtain a predicted route and to determine predicted radio conditions along the predicted route, and a decision circuit configured to, based on the predicted radio conditions, identify one or more first areas expected to have a first type of radio conditions and one or more second areas expected to have a second type of radio conditions different from the first type of radio conditions and to control radio activity while traveling on the predicted route according to the one or more first areas and the one or more second areas.

Abstract: A milling device for milling an antenna structure out of the metal layer of a flexible product, while the product is being passed through a milling gap between a milling cutter and a die, using a light emitter to output a light strip that crosses through the milling gap in or transversely to a running direction of the product, wherein the light strip is dimensioned, and the milling cutter and the die are intended to be arranged, such that the milling cutter and the die shadow the light strip at the two longitudinal edges thereof, before a light receiver receives the light strip, and using the light receiver to output a signal that reproduces the width of the milling gap to a controller, and outputting an adjusting signal at least to an adjusting drive that influences the width of the milling gap between the milling cutter and the die.

Abstract: A process-technology column including a novel liquid distributor which is to be as insensitive as possible to dirt or solids carried in the liquid and which can be operated over a load range as great as possible without the possibility of the delivered liquid being excessively easily entrained by the gas flow which rises in the column is provided. The liquid distributor includes a liquid feed for conducting a liquid and at least 2 nozzles connected thereto for producing a respective liquid jet. The nozzles are flat-jet nozzles for producing a respective flat jet. The flat-jet nozzles are so oriented that the flat jet produced by them impinges on a drain element which is arranged at the liquid distributor and at which the liquid of the flat jet can drain away.

Abstract: A low-load distributor is disclosed for mass transfer columns for applying liquid onto the surface of packing stages of the mass transfer columns with at least one liquid supply, a plurality of liquid dispensing points and dwell time delay devices disposed between the liquid supply and the liquid dispensing points. An exemplery low-load distributor can be easily manufactured for a very low liquid flow rate and is characterized by high operation reliability. A dwell time delay devices can include absorbent open-pored storage material and the flow resistance of the storage material can increase in the liquid flow direction, starting from the liquid supply in the direction towards the liquid dispensing points.
