Abstract: The invention provides an Ethernet-based data transmission method, which is applied to a control system with a plurality of nodes. The method comprises: a first node caches the data needed to be sent (S101); if the current communication macro-cycle comprises the time segment for the first node to send data, the first node sends the cached data in the time segment for the first node to send data within the current communication macro-cycle; if the current communication macro-cycle does not comprise the time segment for the first node to send data, the first node does not send the cached data in the current communication macro-cycle; wherein other nodes do not send data in the time segment for the first node to send data within the current communication macro-cycle, and the communication macro-cycles have same durations and each communication macro-cycle consists of a plurality of time segments with a fixed length (S102). The invention further provides Ethernet nodes and a control system.

Abstract: The present invention extends to methods, systems, and computer program products for securely and efficiently extending data processing pipeline functionality. Data processing agents register, potentially based solely on configuration data contained in the data processing agents, to manipulate data of a data processing pipeline. Configuration data can identify a specified event (e.g., an SMTP verb) the data processing agent is to hook into. Upon detection of a specified event, one or more agents that have registered for the specified event are loaded into secure zones. Process boundaries separate agents from one another and from other processes such that execution of each agent is isolated from other processes. Pipeline related data (e.g., electronic message data) is transferred to each loaded agent. Application Program Interfaces (“APIs”) can be used to transfer data between modules that implement embodiments of the present invention.

Abstract: In a wireless multi-hop relay network arranged in a tree topology, the base station and one or more relay stations are associated as a virtual base station (VBS). The base station and each relay station have a unique virtual base station identifier (VBS-ID) associated with the path defined by the base station and the one or more relay stations. a relay station in the branch uses its VBS-ID for communicating with an attached subscriber station (e.g. a mobile station) such that communications between the base station and subscriber station occur via the VBS. Subscriber station data communications are relayed between the base station and the one or more relay stations over the VBS via a tunnel connection. The VBS is autoconfigurable. Mobility for subscriber stations and relay stations is provided through reconfiguration of VBS's.

Abstract: Digital video effects are described. In one aspect, a foreground object in a video stream is identified. The video stream comprises multiple image frames. The foreground object is modified by rendering a 3-dimensional (3-D) visual feature over the foreground object for presentation to a user in a modified video stream. Pose of the foreground object is tracked in 3-D space across respective ones of the image frames to identify when the foreground object changes position in respective ones of the image frames. Based on this pose tracking, aspect ratio of the 3-D visual feature is adaptively modified and rendered over the foreground object in corresponding image frames for presentation to the user in the modified video stream.

Abstract: An application running on a virtual machine includes a plurality of runtime classes. A class loader can load one or more runtime classes of the plurality of runtime classes into the virtual machine to support an operation on the application. In addition, the class loader can record a context information for each runtime class of the one or more runtime classes. Based on the recorded context information of each runtime class, the one or more runtime classes can be extracted.

Abstract: The present invention provides a method for generating routing paths in a multi-hop network. The multi-hop network includes a base station, at least one relay station, and at least one non-relay mobile station. The routing paths are paths between the base station and the at least one non-relay mobile station via the at least one relay station. The base station broadcasts a path discovery message (PDM) including a path list with a starting point of the path list being the base station. Each of the relay stations receives the PDM and updates the PDM by adding their own respective node identifier to the path list and broadcasting the updated PDM. The PDMs eventually reach the non-relay mobile station. The non-relay mobile stations reply to the base station by sending the base station the updated path list between the base station and the non-relay mobile station.

Abstract: The present invention provides an entropy coding method for coding video prediction residual coefficients, comprising the steps of: firstly, zig-zag scanning coefficients of blocks to be coded to form a sequence of (level, run) pairs; secondly, selecting a type of code table for coding a current image block to be coded according to a type of macro block; then switching and coding each (level, run) pair in the obtained sequence of (level, run) pairs with multiple tables, with the reverse zig-zag scanning order for the coding order of the pairs; at last, coding a flag of End of Block EOB with the current code table. The present invention of an entropy coding method for coding video prediction residual coefficients fully considers the context information and the rules of symbol's conditional probability distribution by designing different tables for different block types and different regions of level. The coding efficiency is improved and no impact to computational implementation complexity is involved.

Abstract: A two step method for determining restoration cycles for a mesh network includes generating a set of possible restoration cycles, and selecting a subset of low-cost restoration cycles on the network. The cost of a restoration cycle may be based, in part, on the availability of capacity on the link to restore traffic with and/or without interference, and network policy. Enabling the restoration cycles to be determined based on the bandwidth capacity of the restoring link, the flows carried by the other link, and other network policy considerations enables embodiments of the invention to account for traffic class, priority, and other traffic considerations when selecting restoration cycles on the network. Identifying arcs on the network with relatively high cost restoration cycles allows portions of the network to be targeted for increased capacity.

Abstract: A fixture can include a test fixture that holds an object whose electrostatic charge characteristics are to be measured, means for moving a piece of rubbing material into contact with the object, and means for rubbing a surface of the object. A method for measuring the electrostatic charge characteristics of an object using a test fixture can include: placing the object in the test fixture, moving a piece of rubbing material into contact with the object and rubbing a surface of the object with the piece of rubbing material for a period of time. The rubbing causes an electrostatic charge to be built up on the surface of the object. The electrostatic charge characteristics of the object can be measured and the measured electrostatic charge characteristics of the object can be displayed.
