Abstract: A system and method may provide an exchange service for providing the price of wireless minutes to wallet applications and other client applications. The system may obtain pricing information for the wireless minutes and provide the pricing information to a wallet application. The pricing information may be provided through a rate server that subscribed to receive the pricing information. The rate server typically also provides exchange rates for currencies for use at wallet applications that are communicably coupled to the rate server. By providing the pricing information to wallet applications, wireless service providers may variably price their wireless services. End users may be able to obtain real-time prices of the wireless services and purchase such services directly using payment accounts associated with a wallet application. For example, a Bitcoin wallet may be used to obtain real-time prices of the wireless services and purchase such services using Bitcoins.

Abstract: The invention relates to an apparatus for the transfer of organic compounds from a first liquid phase to a gaseous phase and from said gaseous phase to a second liquid phase, comprising a packed stripping column (2), a housing (5), a shell (1), a means for introducing the gaseous phase at the bottom end of said packed stripping column (2), a distributor (4) for distributing said first liquid phase onto said packed stripping column (2), causing said first liquid phase to trickle down said packed stripping column (2) counter-currently to the flow of the gas phase and causing the gas stream leaving said packed stripping column (2) at its top end to have a higher content of organic compounds than the gaseous phase introduced at the bottom end of said packed stripping column (2), one or more ducts (9/26) allowing the gaseous phase leaving said packed stripping column (2) to flow downwards to the bottom end of a packed scrubber (3) enclosed in a housing (25), a distributor (12) on top of said packed scrubber (3) ca

Abstract: A device for vaporising a medicament (4). The device comprises a resistive element (9) on which the medicament is deposited. The device also comprises a source of electrical power which can be connected across the resistive element to vaporise the medicament. The element is configured to provide a central cool region (11) on which the medicament is deposited and a relatively hotter region (12) surrounding the cool region. Through holes (13) are also provided. The resistive element may be a mesh, foil or a tile on which a resistive pattern is deposited.
