Abstract: A user-centered push system monitors user activity to build a dynamic model representing probable user interests. The model is used to drive a search for information relevant to these interests. Such information, when located, is pushed to the user. In a specific embodiment, the information is scrolled across a ticker-tape display along the bottom of the user's monitor. Typically, headline and stock quote type information in abbreviated form is scrolled. By clicking on a ticker-displayed abbreviated item, the user initiates a display of a more complete version of the information. In one embodiment, the invention defines a method using a dynamic user model to locate and push information to a client for display. Alternatively a client reformats the information and archives it for later use. In another embodiment, changes in the dynamic model trigger the information pushing.

Abstract: A method and system provides a structured and accessible information repository for an entities personal information. An information server contains a personal information database and a set of information preferences associated with the personal information database. The personal information database contains personal information about an entity, such as name, phone number, address, etc. The information preferences define an entities preferences regarding the conditions of use under which the personal information will be released. When another computer or user of another computer, a requestor, requests personal information from the information server, the requestor then identifies the information it is requesting and provides the conditions under which the information is to be used. The received conditions of use are compared to the set of information preferences to determine if the received conditions of use are acceptable.

Abstract: A method, apparatus, and article of manufacture for managing information through the use of physical objects. An Informative Thing that is a physical object stores a pointer thereon, and the pointer is used to retrieve information associated with the Informative Thing from a network-based system. The Informative Thing provides a user interface that gives the impression of storing information on the physical object, when, in reality, the system stores the information in the network. By hiding the details of information retrieval, information management is greatly simplified. By linking the physical and virtual worlds, users' highly-developed ability to work in the real world is leveraged.

Abstract: A track following servo system is disclosed for use with magnetic tape systems in which magnetic servo track patterns contain transitions recorded at more than on azimuthal orientation across the width of the servo track. The timing of a signal derived from reading at any point across the width of such a pattern varies continuously as the read head is moved across the servo track. The pattern is read by a servo read head whose width is small compared to the servo track pattern. The combination of a wide servo pattern and a narrow servo read head offers excellent position sensing linearity and dynamic range. In the preferred embodiment, the servo read head is also narrow with respect to the data tracks, which provides the additional advantages of superior immunity to position sensing errors caused by defects or temporal variations in the servo read head, defects in the servo pattern on the tape, wear of the head or tape, or debris collection on the head or tape.

Abstract: A system and method for promoting social interaction among computer users displaying similar historical activities on the World Wide Web, based not on a single document access or on a predefined grouping, but on the activities of the users. A history of a group of documents accessed, or a pattern of document access, or the frequency of terms in queries, are gathered and communicated to a place server module. When the histories of two or more computers match each other in accordance with match criteria, a communication group is established by the place server module and communicated to a chat server. The chat server then automatically establishes a chat room for members of the communication group. Each client computer displays a chat window including moving icons representing other members of the group.

Abstract: Dynamically transforming transfer parameters for a media object to allow efficient transmission of the object from a first system to a second system. The transformer may receive transfer feedback and is configured such that it dynamically modifies system constraints or object formatting to overcome system limitations which may slow the transfer. The invention may be integrated into an internet service provider's (ISP) system structure and used to dynamically determine the transfer parameters between the ISP and the end-user. After the ISP accesses a requested internet site and its web site server, a media object from the web site is transferred to the ISP. The ISP transfers the information to the end-user and, during the transfer, receives system feedback regarding bandwidth availability, performance, information latency, and other items of interest. Using this feedback, transfer parameters are automatically selected to increase efficiency of system resources for subsequent media transfers.

Abstract: An image is optically scanned by projecting the image onto an optical sensor through an optical shutter. In an exemplary embodiment, the image is projected through the optical shutter while the shutter is made substantially opaque except for a selected substantially transparent group of contiguous pixels. Then, the contents of the document are scanned by advancing this group of pixels across the shutter in a predetermined pattern. The shutter, for example, may comprise an LCD screen. To scan a document, the document is first placed against the shutter. As a light source directs light through the document and the shutter, the shutter is made substantially opaque except for a selected substantially transparent group of contiguous pixels. Then, the contents of the document are scanned by advancing this group of pixels across the shutter in a predetermined pattern. The document may be placed against either side of the shutter--near the light source or near the optical sensor.

Abstract: Disclosed is a magnetic tape media having addressing data information superimposed on prerecorded track following servo information. The servo information is recorded in magnetic flux transition patterns defining at least one longitudinal servo track. A servo burst pattern of at least two repeated pairs of non-parallel magnetic flux transitions is provided, at least one of which transitions is slanted or otherwise continuously longitudinally variable across the width of the servo track. At least two transitions of the repeated pairs are shifted longitudinally with respect to other of the transitions, the shifted transitions comprising the superimposed addressing data information.

Abstract: A system and method are provided, for use with network communication systems such as Internet terminals having World Wide Web browsers, for indicating to the user a parameter related to a piece of remote information, such as an estimation of a length of time required to download a given piece of information resident at a remote site. Hyperlinks, icons, or menu items are displayed, as in conventional systems. Also provided are indicia which give the user the length of time estimate. The indicia may be displayed concurrently with the displayed hyperlink, or otherwise provided, such as by audio or tactile user feedback. In one preferred embodiment, each hyperlink is accompanied by a red, yellow, or green dot, the color of the dot being representative of the estimated download time.

Abstract: A system and method are provided for use with an communication and information network, such at the Internet World Wide Web, for assisting a user in accessing information stored at remote network sites based on the user's past history of network usage. An archive is maintained of remote sites accessed and instances in which the same remote sites are accessed in sequence. Statistics regarding information such as the number of time a site has been accessed, and the times a given set of sites have been accessed in sequence, are maintained. This information may be displayed upon command. Based on this information, information items are identified which the user is predicted to be likely to want to access. This information is pre-downloaded, without express user command, so that if the user does enter a command, the response time is advantageously fast.
