  • Publication number: 20200008007
    Abstract: A device, e.g. a wireless communication device may obtain information associated with private cellular networks from a provisioning server. The information may provide an indication of coverage area(s) of available private cellular network(s). The device may communicate over a commercial cellular network, and determine, based at least on the information, whether the device is located within the coverage area of any available private cellular networks. The device may connect to a first private cellular network (FPCN) of the available private cellular networks and switch from communicating over the commercial cellular network to communicating over the FPCN at least in response to the determination indicating that the device is located within the indicated coverage area. The device may disconnect from the FPCN in response to a determination that the signal level of the FPCN is below a specified value and the device is not using a wallet garden application.

  • Patent number: 10085948
    Abstract: The invention relates to a method for ionic gelation on solids for encapsulating water-insoluble solids. The method uses negatively charged macromolecules and soluble salts of polyvalent cations as shell-forming materials having a high adsorption on the surface of the solid when subjected to thermal treatment. The shell-forming material represents at least 10% of the weight of the dry microcapsule obtained. The obtained microcapsule can be redispersed in water and treated by altering the environment thereof in order to be used as an encapsulating medium for water-soluble compounds and they can also be used as active ingredients and/or excipients in the production of pharmaceutical or nutraceutical compositions.
