Abstract: The invention permits a user to be given access to digital media content on one set of conditions, for a limited time period made known to the consumer, but then automatically forces migration to a different set of conditions to retain access to digital media content already listened to and to gain access to new digital media content, without the consumer having to manually download or install new software or in some other manner interact in a manner that will lessen the chance of the consumer embracing or accepting the migration.

Abstract: A boiler unit (100) housed in an enclosure, the boiler unit (100) configured to receive a solid state combined heat and power generating device (130). The boiler unit (100) comprises a heating device (110) to produce heat; and a control unit (120) to independently control each of the heating device (110) and the solid state combined heat and power generating device (130). The boiler unit (100) is operable without the solid state combined heat and power generating device (130) being present.

Abstract: This invention enables a user to convert their favourite DRM protected media files, which would otherwise have significant use restrictions, to media files that can be played without limitation of time. This is especially useful where the DRM protected files are supplied as part of a subscription service and the ability to playback those files ends when the subscription ends. This approach relies on the ability to gather playback metrics for the DRM protected media files, to analyse them to determine the user's favourites, and then to provide the user with non-time limited versions of those favourite digital media files. In one implementation, a user's favourite music tracks can still be played, even though a music subscription service has ended.

Abstract: A system (100) for connecting a fuel cell stack to an A.C. grid to provide power thereto is disclosed in which a voltage regulated D.C. bus (110) is provided to be coupled to the fuel cell stack, a bidirectional inverter (120) is coupled to the D.C. bus (110), and is to be coupled between the D.C. bus (110) and the A.C. grid. At least one D.C. auxiliary load (130) of the fuel cell stack is provided coupled to the D.C. bus (110). A D.C. to D.C. converter (140) is provided between the fuel cell stack and the D.C. bus (110).

Abstract: The invention enables digital music content to be downloaded to and used on a portable wireless computing device. An application running on the wireless device has been automatically adapted to parameters associated with the wireless device without end-user input (e.g. the application has been configured in dependence on the device OS and firmware, related bugs, screen size, pixel number, security models, connection handling, memory etc. This application enables an end-user to browse and search music content on a remote server using a wireless network; to download music content from that remote server using the wireless network and to playback and manage that downloaded music content. The application also includes a digital rights management system that enables unlimited legal downloads of different music tracks to the device and also enables any of those tracks stored on the device to be played so long as a subscription service has not terminated.

Abstract: An imaging system 2 is provided comprising a primary gradient coil assembly 52 and a shield coil assembly 42. The shield coil assembly 42 is connected in series to the primary gradient coil assembly 52. The shield coil assembly 42 comprises a first gradient shield coil 82 and a second gradient shield coil 84. The second gradient shield coil 84 is connected in parallel to said first gradient shield coil 82.

Abstract: A gradient coil assembly and a method for manufacturing the gradient coil assembly is provided. The gradient coil assembly includes a first tube extending along an axis including a first conductor. The assembly further includes a second tube disposed generally concentrically about the first tube wherein an inner space is defined between the first and second tubes. The second tube includes a second conductor. Finally, the assembly includes a fiber composite structure disposed in the inner space operatively associated with the first and second tubes to increase a stiffness of the assembly.
