Abstract:
A multiple inverter with neutral line inductor and an active power filter system are disclosed. In the disclosure, the multiple inverter comprises at least two inverter units connected in parallel, the midpoint of the direct current bus in each inverter unit is connected to the neutral line N through the respective neutral line inductor. The multiple inverter can suppress the ripple produced by the neutral line current without increasing the direct current bus capacitor.
Abstract:
A multiple inverter and an active power filter system are disclosed in the invention, said multiple inverter can decrease the volume and harmonics, increase the efficiency and decrease the cost, and can be applied to various occasions. The technical scheme is: the filter assembly in the multiple inverter is installed at the output inductor of the multiple inverter for filtering the harmonics.
Abstract:
Embodiments of the present invention provide a buffer manager and a buffer management method based on an address pointer linked list. In the embodiments, address pointers of all buffer blocks in a buffer are divided into several groups, lower bits of address pointers in each group are used to record a linked list between the address pointers in the same group, and an address pointer which is pointed by one predetermined address pointer of each group and is in a different group is further recorded to upbuild a linked list between the groups. Thereby, an address linked list can still be stored without a RAM with a width equal to a pointer depth and with a depth equal to the total number of buffer blocks in the buffer as required by the conventional art, which greatly reduces hardware resources required.
Abstract:
A method and system for separating hypertext transfer protocol session. The method includes: detecting at the client a condition that a server is to be requested to instantiate same application during same hypertext transfer protocol session; obtaining from the server another hypertext transfer protocol session identifier corresponding to a service instance to be instantiated and setting the hypertext transfer protocol session identifier in the current session as a hypertext transfer protocol session identifier corresponding to a service instance that is to communicate with the server. The system includes: a session manager configured to detect a condition that a server will be requested to instantiate an application during a current HTTP session and a session agent configured to: (i) obtain from the server a second HTTP session identifier and (ii) set the second HTTP session identifier in the current session as a HTTP session identifier.
Abstract:
A method for scheduling communication traffic in an Advanced Telecom Computing Architecture based equipment and a corresponding apparatus are provided. In the method, communication traffic information of traffic processing means in the equipment is collected; based on the collected communication traffic information, a traffic distribution rule for the traffic processing means in next time period is generated; and based on the generated traffic distribution rule, incoming communication traffic of the equipment is scheduled. The method of the invention considers the quality of service and contracted capacity of the whole equipment and the dynamic processing capability and running environment of the traffic processing means, and can balance the loads of the respective traffic processing means in the equipment with asymmetric multi-application configuration well by adaptively adjusting the distribution of the communication traffic, to guarantee the quality of service of the whole equipment.
Abstract:
Word correlations are estimated using a content-based method, which uses visual features of image representations of the words. The image representations of the subject words may be generated by retrieving images from data sources (such as the Internet) using image search with the subject words as query words. One aspect of the techniques is based on calculating the visual distance or visual similarity between the sets of retrieved images corresponding to each query word. The other is based on calculating the visual consistence among the set of the retrieved images corresponding to a conjunctive query word. The combination of the content-based method and a text-based method may produce even better result.
Abstract:
The configurations of a resonant converter system and a controlling method thereof are provided. The proposed resonant converter system includes a resonant converter receiving an input voltage for outputting an output voltage, a rectifying device having a first rectifying switch and a synchronous rectification control circuit coupled to the resonant converter and including a signal generation apparatus generating a weighted turn-off signal to turn off the first rectifying switch at a zero crossing point of a first current flowing through the first rectifying switch.
Abstract:
An identity management method, apparatus, and computer readable article of manufacture tangibly embodying computer readable instructions for executing the identity management method. The method includes: creating an association table to record a first session ID between the user and the first Web application, a second session ID between the user and the second Web application, and an association of the IDs; sending a session ID request containing the first session ID by the first Web application to a return module; receiving the session ID request and searching by the return module for the associated second session ID in the association table according to the first session ID; and returning the second session ID to the first Web application, thereby providing identity management for a user in a Web environment in which a first Web application accesses a second Web application on behalf of the user.
Abstract:
The present invention relates to films made from mixed cellulose esters having low hydroxyl content and certain plasticizers. These films can exhibit +C plate, −A plate, and biaxial Nz behavior, which make them particularly suitable for use in optical applications, such as in liquid crystal displays (LCD) as protective and compensator films.
Abstract:
The aspects enable a processor to concurrently execute a first serial language code (e.g., HTML) embedding a second serial language code (e.g., JavaScript®) during a page load operation by a browser. A parser parses the first serial language code until a segment of the embedded second serial language code is encountered. The segment of embedded second serial language code is extracted for execution by an execution engine, which proceeds concurrently with speculative parsing of the first serial language code. Code generated by execution of second serial language code is evaluated to determine if it is well formed, and a partial rollback and re-parsing of the first serial language code is performed if the code is not well formed.
