Abstract: An improved interactive graphics tool including an algorithm and technique to efficiently and elegantly render smooth lines to build or develop interactive graphics is disclosed. The new algorithm is configured to render an anti-aliased coverage mask for any path, using a single GPU shader program and a single GPU draw call. The present invention is a solution to prior two-dimensional graphics, by providing an automated process to stroke the entire path with tessellation, by rendering to a floating point “coverage count” buffer to tessellate an antialiasing with triangles running orthogonally from the center.

Abstract: An improved algorithm and technique for use in interactive graphics is disclosed. The new algorithm works by keeping three values in fast, memoryless pixel local storage for coverage counting (store the current coverage count at the pixel being covered), original framebuffer color (stores the color that was in the framebuffer at the pixel being covered immediately before the current path starts rendering), and the path ID (stores the unique ID of the last path to be drawn at the current pixel). The framebuffer is accessed from a fourth, texture-backed, pixel local storage plane.

Abstract: A device for cleaning medical implements is disclosed, in particular a device for cleaning vascular or other fluid access sites. The device includes a cap having an opening to receive an access site. The cap may be used in the following manner: A healthcare worker may, with gloved hands, open the cap packaging and place the cap over the port of a medical implement to be cleaned. The healthcare worker may wipe the site by either applying a turning motion or by simply pushing the cap onto the port. The cap could then remain secured in place by threads other mechanisms. A cap in place on a medical implement may be a positive indication that a desired site of the medical implement is clean. The cap may include a disinfecting substance.

Abstract: A system and method for creating a design tool using a clockwise fill rule is disclosed. The system creates a design tool that may be used in an editor implemented as a feature of application on a server. In some embodiments, the design tool in accordance with the present invention provides an interface to a user who may create a path of contours using the design tool. For each contour, the design tool is configured to provide an interface function for the user to categorize each contour as either a “hole” or a “fill.” For contours designated as “hole,” the design tool is configured to automatically order the points in a counterclockwise fashion, without requiring user thought or action. In some embodiments, for contours designated as “fill,” the design tool automatically orders the points in a counterclockwise fashion without requiring user thought or action.

Abstract: An improved system and method for rendering a path using a clockwise fill rule is disclosed. The improved system and method uses an algorithm and technique for use in interactive graphics. The new algorithm is configured to handle rendering scenarios in which a pixel is hit twice with positive coverage.

Abstract: An improved algorithm and technique for use in interactive graphics is disclosed. The new algorithm is configured to render a path, which may be stroked quickly using shaders. However, it should be recognized that it is common for path strokes and fills to be interleaved, and an application can quickly become bottlenecked by GPU state changes if it uses a separate shader for stroking. The present invention discloses a single-pass GPU shader that is capable of either stroking or filling a path, and can batch together any number or combination of strokes and fills.

Abstract: A virtual network has virtual machines on physical devices connected to network interfaces each coupled by tunnels (100) through a forwarding network (40), each interface having a forwarding address in an address space of the forwarding network, each network interface having a reconfigurable address mapper (320) for determining a forwarding address for a packet, and encapsulating the packet with its forwarding address so that the forwarding network can deliver the data packet to the remote physical device having that forwarding address. Such encapsulation enables virtual machines on different physical devices to communicate transparently to the underlying forwarding network. Virtual networks can be created to suit their applications yet use or share existing forwarding networks, while protecting the forwarding network from interference by the virtual machines, and maintaining isolation between virtual machines.

The user navigates through the gallery using camera buttons. Methods relating to implementing the virtual-reality photo gallery are also disclosed.

Abstract: A method of administering a network comprises the steps of: detecting the occurrence of a triggering event alerting an administrator to the presence of a user entity on the network, the triggering event being selected from the group consisting of: (i) allocation of a network address to the user entity; (ii) alteration of the user entity's network address; (iii) an action by the user entity causing resolution between a network address and an identifier; (iv) association of the user entity's network address and an identifier. Upon detecting such an event, the user entity having the network address is scanned for vulnerabilities by sending at least one outward packet to it, for example seeking to establish a connection on a particular port, and the response, if any, is then used to determine whether is vulnerable to known malicious code.

Abstract: Access to a data processor is controlled by determining if a requested function command conforms to a set of parameters, the set of parameters being derived from previously executed function commands. If the requested function command does not conform to the set of parameters the data processor is controlled to temporarily hold the execution of the requested function commands.

Abstract: Control of access to data within a first data processing device is provided. The data processing device contains at least one data item which has a use policy associated with it. In response to a request from or a requirement of a second data processing device to perform an operation on the data item, the first data processing device seeks information about the ability of the second data processing device to respect conditions specified in the policy and on the basis of a comparison between the policy and the ability of the device to satisfy the policy, the first data processing device decides whether to allow the operation to be performed.
