Abstract: A software based system for facilitating streaming of media files to a device over a wide area network (WAN) includes an agent process, an authentication process, a client services process and a client process. The agent process catalogs local media files and advises the authentication process of its availability on the WAN and the address at which it may be contacted. The client process contacts the client services process to obtain, after authenticating with it, the WAN address of the agent process and contacts the agent process to receive information or meta-data describing the media files available for streaming. The client process obtains information for forming a URI or playlist, that it then passes to a media player to request the stream over the WAN. Alternately, the client process may direct the agent process to pass the URL to another client process on, for example, the same local area network.

Abstract: A composite strip 10 windable to form a helical pipe is disclosed. The composite strip 10 comprises: an elongate plastic strip 11 having a base portion 12 and at least one lengthwise extending rib portion 20 upstanding from the base portion 12; and an elongate reinforcing strip 30 extending lengthwise and supported laterally by the rib portion 20, the reinforcing strip 30 having a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion 12. When wound into a helical pipe, the reinforcing strip 30 reinforces the pipe against radial crushing loads. A bead 40 seals the reinforcing strip 30 from the environment. Desirably the composite strip 10 further comprises: a planar lamina 50 extending lengthwise and bonded to the base portion 12, the lamina 50 having a higher Young's modulus and strength than those of the plastic strip 11. The lamina 50 greatly improves the pressure rating of a pipe wound from the strip 10.

Abstract: A system and method for storing a playlist of media files that is accessible from various locations in a network. In one aspect, the playlist is accessible from multiple users of the network. A method is also described for arranging the media files of a playlist. In one aspect, the method for arranging the media files is based in part on implicit and/or explicit user behavior.

Abstract: A user interface and associated computer readable medium for a user interface within a media management application. In one aspect, the user interface comprises a plurality of panes displaying a list of one or more media file sources, a list of user selectable media file identifiers, selected information associated with the listed media file identifiers, instructional information as to how a user can cause one of the panes to display selected information associated with the listed media file identifiers and a media player control interface. In one aspect, the user interface comprises panes displaying an instant messaging platform as a media file source and a list of indicia representing messaging users that a user communicates with. In another aspect, selecting the indicia representing a messaging user can cause a pane to display information associated with media files found in a media library of the selected messaging user.

Abstract: A method, system, and media management application for providing a user access to a media file from multiple locations on a network. In one aspect, a user communicates a desire to access a media file at a future time and is able to access the bookmarked media file from various locations on a network at any future time. In one aspect, the media file is available from multiple locations on the network and in different media formats.

In one aspect, the method allows a user to browse and/or exchange media files with other users via a network using an instant messaging component.

Abstract: A method and a computer readable medium for searching for media items from a network of users using a media management application and an instant messenger platform and a system for handling searches such searches. In one aspect, the method comprises receiving from a user having a group of messenger friends, a search request for a media item, identifying other users of the instant messaging service to form a list of candidate users, searching media items associated with each candidate user to develop a search result that fulfills the search request, and returning to the searching user the search result comprising information identifying which candidate user is associated with a media item source that can act as a source of a media item identified in the search result.

Abstract: An hydraulic control arrangement (66) in association with a pipe relining machine Includes fluid pressure supply and return lines (32, 33), a motor controller (80) to control a motor (67) and a radial position controller. The radial position controller supplies fluid under pressure to a radial positioning arrangement (46) to set diameter of a relined pipe. The radial position controller has a first normally closed valve (83) supplying fluid under pressure to the radial positioning arrangement (46) and a second normally open valve (84) allowing fluid to be withdrawn from the radial positioning arrangement (46). The arrangement (66) allows the pipe relining machine to be withdrawn in the event of a failure.

Abstract: A device for controlling a seismic cable that is towed behind a vessel (1), so that the cable follows a path that is displaced laterally in relation to the path of the vessel, comprises a frame structure (6, 7) extending transversely to the towing direction and outwardly from the area of gun suspension from the cable having longitudinal frame members provided with intermediate transverse members extending obliquely or in a curved manner whereby the front ends of the transverse members, as seen in the towing direction, are disposed further outwards laterally than the rear ends of the transverse members. When towed, the frame will this be forced outwardly by the water flowing through the frame structure and the desired lateral displacement will be achieved.
