Abstract: A technique utilizes a search query having a set of clauses. The technique involves displaying, by a processor, the set of clauses of the search query onto an electronic display. Each clause includes a selection cell describing a selectable operation. The technique further involves receiving, by the processor, a mouse click input from a mouse apparatus. The mouse click input includes coordinates identifying a location that resides within the selection cell of a particular clause. The technique further involves change, by the processor, the selectable operation described by the selection cell of the particular clause between an editing operation and a Boolean operation in response to the mouse click input. Such a technique minimizes user typing and navigation demands, and offers a compact format and considerable power and flexibility when constructing and/or editing a search query.

Abstract: Systems and methods for displaying network node ports and related information in a network topology display. The user is able to clearly view ports of a connection device in the network and to view additional port information, such as the port type and the port number, for connected and unconnected ports of a network connection device. In addition, the user is able to toggle between a “show ports” mode and a “hide ports” mode for each connection device to view detailed information about the connection device ports or to hide the information in order to simplify the display.

Abstract: A method for displaying storage network information in a user interface. The method includes identifying a topology map for a storage network and gathering operating information, which is processed to determine a performance parameter, such as utilization. A performance monitoring display is generated including a topology map and a graphical representation of the performance parameter, which is positioned in the display relative to the components for which the parameter applies. The graphical representation can be a pair of parallel dashed lines between communicating components. The dashes in the lines are moved using a speed coding scheme representative of the performance parameter, e.g., with faster speeds used to show higher ranges of utilization, and the direction of movement matches data flow. The dashed lines are colored using a color coding scheme and the line segment lengths vary in association with the performance value.

Abstract: A method of displaying nodes within a network topology. Using a processor coupled to a display screen, the method involves forming a first layer of a multi-layer representation wherein at least two nodes are represented separately; and grouping the nodes of the first layer into group nodes to form a second layer in the multi-layer representation. In addition, the method groups the group nodes of the second layer into a third layer, the third layer having at least one connected-superset node containing group nodes with nodes connected to each other, and at least one isolated-superset node containing group nodes having nodes isolated from each other. The method displays the superset nodes in the third layer so the connected-superset node is separate from the isolated-superset node and such that the connected-superset node is selectively expandable to display group nodes and connections between the nodes, and the isolated-superset node is selectively expandable to display group nodes of the second layer.

Abstract: The present invention provides a systematic automated procedure for routing connections in display applications such as a network topology interface. In one embodiment, the invention first creates an “ideal routing” between two given nodes. The ideal routing includes three segments that join the nodes. If any obstructions exist on the original segments of the ideal routing then the procedure systematically reroutes the appropriate segments to achieve an efficient, visually cohesive and organized routing. The routing procedure operates at different layers, groups and subgroups of nodes. By using the procedure with a layered design it is possible to achieve fast, uniform and effective routing in very complex systems with many nodes and inter-node connections.

Abstract: A computer user interface to display connections in a network topology display. Different visual representations are used for a single and multiple connection types. If there is only a single connection between nodes then a simple line is used. If there are multiple connections between nodes then a line that terminates in a “fork,” or small U-shape symbol, is used to indicate a multiple connection line. The termination symbol, or “connection endpoint symbol,” is adjacent to a node at each end of the line. In general, many types of symbols can be used. For example, a square, diamond, or other basic shape can be used as the connection endpoint symbol. Also, the invention provides for a symbol to be adjacent to, or in the vicinity of, a node. For example, the number of connections represented by a line can be shown near the node, or connection, to which the number relates. A feature of the invention provides for details of the multiple connection line to be displayed upon user selection.

Abstract: A method for simplifying display of complex network connections in a user interface. The method includes displaying a network topology display having multiple interconnected nodes. The nodes, such as network hubs or switches, are connected to one or more of the other nodes via line segments or connection paths. The segments are intentionally overlapped to simplify the visual representation of the network topology display. To remove ambiguity as to which nodes are connected to each other, the method includes using distinguishing connector segments to connect the orthogonal portions of the line segments or connection paths. The connector segments are configured to indicate which nodes are connected and may include any polygonal structure. In one embodiment, the connector segments comprise rounded corner connectors between two orthogonal segments that effectively indicate connected node pairs.

Abstract: Disclosed is a method of operating a graphical user interface to allow a user to selectively enable or disable a data path that is connected to communications between a first node and a second node of a switched network, such as a storage area network (SAN). The method comprises the steps of displaying a graphical representation of the datapath on a display, displaying a cursor on the display whose image position on the display is under control by the user, detecting when the image position of the cursor is in a predetermined distance from the graphical representation of the datapath, highlighting the graphical representation of the datapath when the displayed cursor is detected to be within the predetermined distance, and then selectively enabling or disabling the datapath of the network that corresponds to the highlighted graphical representation in response to an input signal controlled by the user.

Abstract: A method which makes it possible to produce an optical device containing a semiconductor laser emitting a beam of parallel light which is positionally located with respect to a mechanical axis. It consists in positioning the laser with respect to an objective along three mutually orthogonal directions, and thereafter in assembling this laser and objective by means of bonding.

Abstract: The track of a videodisk is followed by a reading light beam produced by a device comprising a reading head fixed on a carriage which forms part of the moving system of a videodisk reader-recorder and is capable of radial displacement along the disk. An objective support frame is capable of displacement in a vertical direction with respect to the carriage in order to maintain focusing of the reading beam and of rotational displacement with respect to the carriage about a transverse axis at right angles to the radial and vertical axes in order to maintain the light beam on the track-following path. Flat coils located vertically in a plane parallel to the carriage path and placed within air-gaps of magnetic circuits serve to develop vertical forces which lift the reading head and initiate the vertical and rotational displacements by means of a differential supply circuit.

Abstract: A semiconductor laser source optical head for reading reflecting information carriers. The information is recorded on a track carried by the carrier in the form of a relief modulation. The device comprises a laser and an optical projection device for forming a reading spot which is an image of the source on the carrier. The laser is positioned on the optical axis of the optical device in such a way that the beam from the laser substantially illuminates half the entrance pupil of the optical system. The return beam reflected by the support emerges on the other half of the pupil. A deviating member is placed on the path of the return beam in order to displace the beam relative to the outward beam. Detection cells are conveniently placed in a detection plane parallel to the supports.

Abstract: An optical device for forming a stigmatic image of a laser source positioned at a predetermined point is intended to illuminate a reflecting surface while also providing a separation between the beam emerging from the source and the beam reflected from the surface. The device comprises a cube placed against a converging lens, the dimensions of the assembly thus formed being such that the cube face remote from the lens passes through a Weierstrass point of the spherical refracting surface formed by the lens. The laser source is positioned at the Weierstrass point. The cube is formed by two prisms cemented together, the interface being treated so as to have a polarization-separating effect.

The access device is provided in addition with a low-weight moving system comprising at least one electric circuit forming a flat coil which is capable of sliding vertically within the air-gap and is so arranged that horizontal conductors are placed within the air-gap. Radial tracking and track-to-track transfer can be carried out by means of an electric circuit, at least one vertical conducting element of which is placed within the air-gap. Fast access is obtained by displacing this low-weight moving system.
