An apparatus for executing components based on a thread pool includes a component executor configured to have a set priority and period, to register components having the set priority and period, and to execute the registered components. Further, the apparatus for executing the components based on the thread pool includes a thread pool configured to allocate a thread for executing the component executor; and an Operating System (OS) configured to create an event for allocating the thread to the component executor in each set period.

Apparatus and method for executing components based on thread pool

A component composing apparatus using virtual components in component-based robot software development, includes a component repository configured to store a plurality of components having at least one port; and an application diagram generation unit configured to create an application diagram by selecting the components stored in the component repository. Further, the component composing apparatus includes an information repository configured to store the components within the application diagram and port information of the components within the application diagram and port connection information between the components within the application diagram; and a virtual component processing unit configured to create the virtual components for components selected by a user among the components within the application diagram.

An apparatus for thread processing robot software components includes a data port unit for storing input data in a buffer and then processing the data in a periodic execution mode or in a dedicated execution mode; an event port unit for processing an input event in a passive execution mode; and a method port unit for processing an input method call in the passive execution mode by calling a user-defined method corresponding to the method call. In the periodic execution mode, the data is processed by using an execution thread according to a period of a corresponding component. In the dedicated execution mode, a dedicated thread for the data is created and the data is processed by using the dedicated thread.

A configuration method of a method port arrangement for robot software component includes: generating a requester method port module and a provider method port module; generating a requester method module and a provider method module depending on application of a method module to be generated in the component; registering the requester method module in the requester method port module and the provider method module in the provider method port module; and registering, in a method port management module, the requester method port module and the provider method port module where the requester method module and the provider method module have been registered. The method further includes establishing the requester method port module to be operated by interconnecting the requester method port module and the provider method port module; and executing input and output operations to/from the requester method port or the provider method port depending on application of the component.

Method port arrangement and configuration method thereof for robot software component

An apparatus for performing fault tolerance against a failure occurring during driving robot software components includes: a component executor for executing the robot software components, which are assigned with one thread from an operating system and have a same priority and cycle, by using the assigned thread; and an executor monitor for periodically monitoring the operation of the component executor and determining whether or not there is a failure in the robot software components executed by the component executor. The apparatus further includes: an executor manager for generating the component executor which is assigned with the robot software components having the same priority and cycle and, when the executor monitor determines that there is a failure in the execution of the robot software components, generating a new component executor.

Fault tolerance method and apparatus for robot software component

Provided is a path-token-based web service caching method including determining whether or not stored cache data exists when a web service call request exists, and when the cache data does not exist, creating a predetermined path-token set and a predetermined tag data set based on a message schema of Web Services Description Language (WSDL), and creating a request Simple Object Access Protocol (SOAP) message, creating a request SOAP message template by using a path-token for the created request SOAP message, and calling the web service, and creating cache data including the tag data set, input values set, the request SOAP message template, the request SOAP message, and SOAP binding information. Accordingly, the method can solve the problems of a conventional web service caching method whereby the method can not cope with change in the number of inputs, and an exact input position is not searched for when an input value is changed. Therefore, it is possible to implement an efficient web service call environment by web service caching.

Path-token-based web service caching method

A system and method for aborting web services automatically. An application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.

System for aborting web services automatically and method thereof

A method for electronically checking documents as to their authenticity is disclosed, in which an official seal is not put on the document, but the document itself shows to be notarized, and the authenticity of a document can be electronically confirmed. The method for electronically checking the authenticities of documents includes the step of forming a document with an electronically authenticity-checking format for showing that a document has been notarized without using an official seal (first step). It further includes the step of judging as to whether the document with the electronically authenticity-checking format has been really notarized (second step). Therefore, a notarization feature can be provided even to facsimile documents and to printed-out documents. Therefore, a document having a notarization feature can be transmitted even to a remote place, thereby preventing forgery of documents.
