Abstract: A method of scanning a chemical processing vessel and diagnosing a problem within the chemical processing vessel and/or a problem with a process occurring within the chemical processing vessel, the method comprising: scanning the chemical processing vessel with at least one radiation source and at least one detector to generate density profile data for the chemical processing vessel; saving the density profile data; generating a representation of the chemical processing vessel; associating the density profile data with the representation of the chemical processing vessel whereby each data point of the density profile data is associated with a corresponding location along the representation of the chemical processing vessel indicating the location from which the data point was obtained; displaying the representation of the chemical processing vessel alongside the associated density profile data on a user interface, wherein the user interface is configured to enable a user to select a portion of the representat

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.
