摘要:
Provided are a system and method for determining whether to provide service and a content of the service based on ubiquitous-based context information. The method includes the steps of registering at least one context-aware service (CAS); determining whether sensors associated with the CAS are registered; when all the sensors are registered, checking all contexts associated with the CAS; upon receipt of a CAS request, receiving context information from the sensors and determining whether the context information satisfies the contexts; and providing the CAS if the context information satisfies at least one of the contexts. With the flexible engine determining whether to provide service corresponding to a current context even though all context information constituting the CAS is not collected, information is quickly provided upon receipt of a service request from a user.

Provided is a system for executing applications stored in an application server on a mobile terminal. The mobile terminal includes: a mobile terminal input/output processing unit for processing data input via an input device of the mobile terminal and data to be output via an output device thereof; a mobile terminal information transmitting and receiving unit for transmitting and receiving data to and from the outside via an Internet network; and a data processing unit for decoding the structural data received from the mobile terminal information transmitting and receiving unit and sending the decoded data to the mobile terminal input/output processing unit, or encoding data received from the mobile terminal input/output processing unit and sending the encoded data to the mobile terminal information transmitting and receiving unit. The application server includes an application storage unit for storing an application to be executed by the mobile terminal; a server information transmitting and receiving unit for transmitting and receiving data to and from the outside via the Internet network; and a server application managing unit for performing and controlling configuration management of registering, modifying or deleting the application information to be executed at the mobile terminal, and converting a result of executing the application to be output to the output device of the mobile terminal.

A portable communication device is disclosed. The portable communication device comprises a first housing extending in the longitudinal direction thereof, a second housing rotated about a first hinge axis perpendicular to the longitudinal direction of the first housing such that the angle between a bottom surface of the second housing and a corresponding top surface of the first housing varies, and a cylindrical hinge housing disposed at one end of the first housing while a portion of the cylindrical hinge housing protrudes outward from the first housing. The first hinge axis extends in the diametrical direction of the cylindrical hinge housing wherein the second housing is attached to the cylindrical hinge housing while the second housing is rotated about the first hinge axis. The cylindrical hinge housing has a second hinge axis extending in the axial direction of the cylindrical hinge housing so that the second housing can rotate about the second hinge axis. The second hinge axis is perpendicular to the first hinge axis.

A sound penetrating display apparatus for outputting sound having an object-based position coordinate effect is disclosed, which apparatus comprises a plurality of pixels, a plurality of holes which are distributed in an OLED (Organic Light Emitting Diode) display panel in a certain dense in order for sound from a speaker disposed at a back side of the OLED display panel to penetrate, a driving circuit for driving the OLED display panel, a protecting layer which is attached to a back side of the OLED display panel or is disposed close to the same and is formed of holes matching with the holes of the panel, and a plurality of matrix speakers which are disposed at a back side of the OLED display panel.
摘要:
A method of task assignment in a distributed processing system including a plurality of processors is proposed. The method of task assignment includes calculating utilities of tasks to be processed in execution units included in each processor and arranging the calculated results in descending order; calculating utility difference values between the execution units included in each processor and outputting a highest difference value; comparing a utility of the task with the output highest difference value; designating the task to be assigned to the execution unit having the lowest utility in a processor in which the highest difference value is generated when the utility of the task is less than or equal to the output highest difference value; repeating the calculating, comparing, and designating in the order of the arranged tasks; and assigning the tasks to the designated targets.

A method, a device, and a system for real-time publish subscribe (RTPS) discovery based on a distributed hash table (DHT) are provided. The method for RTPS discovery based on a DHT includes: registering, by a participant peer of participants, the participants in a distributed hash table (DHT) of an overlay network; obtaining location information on relative participants to be discovered from the DHT; sharing information on entities of the relative participants by exchanging a discovery message with the participant peer based on the location information on the obtained relative participants; and performing handshaking between the entities of the participants and the entities of the relative participants. Therefore, the exemplary embodiments of the present invention can rapidly and efficiently perform the discover of the participants based on the DHT.
