  • Publication number: 20140155072
    Abstract: A method is provided for operating a mobile terminal operable in at least one communication network for a change of connection in a communication network. The method includes evaluating an information item regarding the local position of the mobile terminal in a service area of a radio cell of a first type with regard to an entry of the mobile terminal into the service area of a radio cell of the first type, which entry is to be expected within a predefined time interval. The method also includes suppressing a change of connection of the mobile terminal to a radio cell of a second type if, based on the result of the evaluation, the entry of the mobile terminal into the service area of the radio cell of the first type can be expected within the predefined time interval.

  • Publication number: 20120270942
    Abstract: Disclosed herein is a device for the application of agricultural active agents, wherein the device is suitable to be brought to the site of action in a manner temporally and spatially separated from the production process, and comprises a dispenser and non-water-soluble nanofibers and/or mesofibers charged with agricultural active agents. The polymers from which the nanofibers and/or mesofibers are made are preferably biodegradable. The agricultural active agents are selected from fungicides, herbicides, batericides, plant growth regulators and plant nutrients. These are preferably pheromones, kairomones and signaling substances. Furthermore, a method for the production of this device is disclosed, wherein the nanofibers and/or mesofibers charged with active agents are produced via electrospinning. The device is suitable to be used to bring agricultural active agents to the site of action in a manner temporally and spatially separated from the production of this device.
