Abstract: A multi-user animation process receives input from multiple remote clients to manipulate avatars through a modeled 3-D environment. Each user is represented by an avatar. The 3-D environment and avatar position/location data is provided to client workstations, which display a simulated environment visible to all participants. A text or speech-based bulletin board application is coupled to the animation process. The bulletin board application receives text or speech input from the multiple remote users and publishes the input in a public forum. The bulletin board application maintains multiple forums organized by topic. Access or participation to particular forums is coordinated with the animation process, such that each user may be permitted access to a forum only when the user's avatar is located within a designated room or region of the modeled 3-D environment.

Abstract: A method of testing a tubular member and selecting tubular members for suitability for expansion by subjecting a representative sample the tubular member to axial loading, stretching at least a portion of the tubular member through elastic deformation, plastic yield and to ultimate yield, and based upon changes in length and area calculating an expandability coefficient indicative of expandability of the tubular members and selecting tubular members with relatively high coefficients indicative of good expandability.

Abstract: An apparatus for the radial expansion and plastic deformation of a tubular member.

Abstract: A multi-instance, multi-user animation platform includes a plurality of modeled parallel dimensions in a computer memory. Each of the parallel dimensions may be an independent model of a physical, three-dimensional space having corresponding features such that the parallel dimensions are recognizable as counterparts to each other. Avatars are located within corresponding ones of the parallel dimensions so as to prevent over-population of any one of the parallel dimensions by avatars. Avatars are animated within different ones of the parallel dimensions using input from respective users to provide virtual-reality data. The virtual-reality data may be configured to cause remote clients to output an animated display of a corresponding one of the parallel dimensions and avatars therein.

Abstract: A method of expansion.

Abstract: A method and apparatus for providing audio advertisements in a computer network enables Web sites to deliver audio advertisements that cannot be bypassed by a visitor. More particularly, an advertising or sponsoring Web site receives a request from at least one user for delivery of a user-selected Web page associated with the Web site. The Web site selects at least one audio advertisement from a plurality of audio advertisements for delivery to the user in conjunction with the user-selected Web page. The Web site then delivers the audio advertisement to the user via the network in a format that precludes the user from controlling the manner of playback of the audio advertisement.

Abstract: A method and apparatus for managing ownership of virtual property accessible to users is provided by a computer-implemented system connected to a network. This method and apparatus further comprises maintaining an inventory of virtual properties, managing ownership of virtual properties, and allowing use of virtual properties by corresponding property owners within corresponding network spaces. In particular, virtual properties are purchased from a system by user computers, wherein virtual properties may be accessed by a user and/or sold or traded to other users which may include auction websites.

Abstract: An expandable tubular liner includes a first tube, a second tube, a mechanical coupling for coupling the first and second tubes, and an insert coupled to the mechanical coupling. The insert is capable of forming a metallurgical bond with at least one of the tubes when energy is injected into the insert.

Abstract: A self-lubricating expansion mandrel includes a system for lubricating the interface between the self-lubricating expansion mandrel and a tubular member during the radial expansion of the tubular member.

Abstract: A radial expansion system.

Abstract: A method and system for organizing and displaying information about Internet Web pages creates Web maps. The Web maps display a summary of the information that a Web page provides access to, in a format that facilitates a rapid assessment of what may be accessed through a Web site's home page, or through any Web page on the Web site. Preferably, Web maps are displayed on a Web page, or within a frame of a Web page, by an Internet browser application. A set of Web maps may be automatically generated by a search engine or directory in response to a user's search request. Alternatively, a user may request that a Web map be produced for a particular Web page of interest. The Web maps are preferably generated by a Web server, or by an application running in the background of a user's computer, so that the user may perform other tasks on the user's computer while the Web maps are being generated.

Abstract: A multi-user animation process provides a modeled three-dimensional (“3D”) environment and virtual reality (“VR”) data to remote clients. The VR data comprises data for animating avatars in the modeled 3D environment. The remote clients provide input data including an ignore signal in response to commands from corresponding users. The multi-user animation process receives the input data, aggregates the input data from each of the remote clients, filters the aggregated input data in response to the ignore signal by removing the input data of a selected one of the remote clients from the aggregated input data, generates updated VR data for each of the remote clients using the filtered aggregated input data and provides an updated modeled 3D environment and the updated VR data to the remote clients. The remote clients display the updated modeled 3D environment and the updated VR data to the corresponding users.

Abstract: Two or more participants provide inputs from a remote location to a central server, which aggregates the inputs to animate participating avatars in a space visible to the remote participants. In parallel, the server collects and distributes text chat data from and to each participant, such as in a chat window, to provide chat capability in parallel to a multi-participant animation. Avatars in the animation may be provided with animation sequences, based on defined character strings or other data detected in the text chat data. Text data provided by each user is used to select animation sequences for an avatar operated by the same user.

Abstract: A method for managing a multi-user animation platform is disclosed. A three-dimensional space within a computer memory is modeled. An avatar of a client is located within the three-dimensional space, the avatar being graphically represented by a three-dimensional figure within the three-dimensional space. The avatar is responsive to client input commands, and the three-dimensional figure includes a graphical representation of client activity. The client input commands are monitored to determine client activity. The graphical representation of client activity is then altered according to an inactivity scheme when client input commands are not detected. Following a predetermined period of client inactivity, the inactivity scheme varies non-repetitively with time.
