Abstract: Techniques for performing inline searches in an instant messaging environment are provided. A user can implement a web search in an instant messaging window by entering a search query. A search query can be preceded by a predefined search trigger to identify the associated text as the search query. The search query is sent to an Internet search server, which processes the query and gathers search results. One or more of the search results is displayed inline in the instant messaging window to the sender and the recipient. The search result can be in XML or HTML format and can include graphics and hyperlinks.

Abstract: Techniques for integrating instant messaging with Internet search features are provided. An instant messaging (IM) application allows users to launch a search of the Internet or the World Wide Web for information about another IM user or another topic. If an IM user wishes to locate information relating to a friend, a search is performed through a database of registered IM members to locate a user profile for the friend. If the friend's profile is found, the profile is displayed to the IM user. An IM application can link to an Internet search engine to search the Internet for web sites relating to the topic or person. Search results from an Internet search can be sorted based on information about a friend that is stored in the friend's user profile.

Abstract: By varying the levels of detail associated with items in an ordered collection of information, items may be organized in a way to emphasize details about item of current interest. Displaying varying levels of detail about items in an ordered collection of information involves determining a focus, and based on their relative location to the focus adding additional detail to other items displayed from the collection of information. For instance, a user browsing a web search results list typically only sees a few essential details such as the name, link, and brief abstract about each item in the list. Providing the user with varying levels of detail about each item in the list helps them decide to where they want to navigate.

Abstract: A nucleic acid having a first nucleotide sequence encoding an infectious hepatitis C virus, a second nucleotide sequence encoding a ribozyme, and an inducible promoter operably linked to the first and second nucleotide sequences, the ribozyme being configured to remove a 3? sequence unnecessary for replication of the infectious hepatitis C virus from a transcript initiated by the inducible, is described. A cell containing the nucleic acid and methods of using the cell are also described.

Abstract: The subject invention provides a parallel or closed loop mechanism for moving and positioning a member in space. The mechanism includes three branches each provided with at least two link members being serially connected together by a spherical elbow joint whereby the first and second link members are rotatable with respect to each other about any axis passing through a center of the first joint. The mechanism is provided with actuators for moving each branch and the first links of each branch are rigidly connected at an end portion thereof to the actuator means. The mechanism includes three revolute joints each defining a longitudinal axis of rotation. Each revolute joint is connected to an associated second link member so that the longitudinal axes of all third joints intersect at a point and the revolute joints are interconnected so that the three branches form three parallel or closed loops.

Abstract: A four degree of freedom manipulator which comprises a pair of elongate rigid legs connected by a joint. The joint acts as an end-effector or an end-effector is attached thereto, The legs effectively intersect at a point in the joint. The positioning end of each leg is attached to a two degree of freedom positioning mechanism that can position it in a two dimensional plane. The connection between the leg and the positioning mechanism has two passive rotational degrees of freedom. Preferably five bar mechanisms are used as the positioning mechanisms. The manipulator can control the position and orientation of an end-effector.

Abstract: Apparatus and method for forming an integral laid fibrous web from multiple fiberizable components, characterized by generally discrete homogeneous compositional zones therein. The system comprises a housing having in its outer surface (i) inlet slot(s) for introduction of fiberizable materials into the housing and (ii) a discharge slot generally laterally coextensive with and translationally spaced from the inlet slot(s), for discharge of fiberized materials from the housing. A translatable body is positioned in the housing for translation therein, having a plurality of blades on its outer surface. The outer surface of the translatable body and the housing have a space therebetween wherein the blades travel during translation of the translatable body. First and second fiberizable components are fed to inlet slot(s) wherein the respective fiberizable components are at least partially laterally isolate relative to each other during the feeding.
