Radio communication system, radio communication apparatus, radio communication method, and computer program
An autonomously dispersed type wireless network is suitably formed with communication stations avoiding collision of beacons transmitted one to another. In the event that the range of reach of airwaves change and a receivable state is created and beacons collide, a communication station changes the beacon transmission position of itself in response to receiving a beacon from another station at a timing immediately prior to transmission to its own beacon. Also, in the event that beacon collision is exposed due to emergence of a new communication which can perform reception from two systems out of airwave range of each other, the newly-participating station requests one of the communication stations of which the beacons are colliding to change the beacon transmission timing. |

Ghost artifact detection and removal in HDR image creation using graph based selection of local reference
In high dynamic range (HDR) image creation, a ghost artifact detection method divides the images (brackets) into multiple tiles, and selects one bracket for each tile as the local reference bracket. The local reference brackets are selected via optimization of an objective function which includes both a component that measures exposure quality of individual tiles and a component that measures correlation between neighboring tiles. The minimization can be realized by constructing a graph for the objective function and calculating a minimum cut of the graph using a graph cut algorithm. Graph examples for three and four image sets are given. Ghost artifact detection is then performed on a tile-by-tile basis by using the local reference bracket for each tile. Ghost maps are generated this way and used for HDR image creation.

Idle state triggered constrained synchronization of shared content items
A content management system synchronizes content items across client computing systems connected by a network. Each client device has a storage allocation for synchronized shared content items. If the storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, or open a large content item remote to the client device, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space for the initial request to be completed while maintaining user access to all synchronized shared content items. The processes of replacing content items with shadow items may be completed while the client device is idle. |

A network condition prompts a hybrid device to select a new path for a packet stream. A path update may occur in response to a change in network topology or a traffic loading condition (e.g., congestion or saturation of a link in the current path). Path selections may be made at each hybrid device in the path from a source hybrid device to a destination hybrid device. A path update procedure may be dependent upon path selection procedures that are optimized for a hybrid network in which multiple hybrid devices may be utilized for a particular path. Path update for load balancing may be dependent upon whether a packet stream is elastic or non-elastic. |

Communication between application components distributed among devices
Disclosed are various embodiments for facilitating communications between application components that are distributed among many devices across a network. This allows for the application to execute as if on one device even though the application components are on many devices. A component interface is generated for the application components. The component interface intercepts communications sent from an application component, locates the intended receiving application component, and generates a component interface packet with the location.

Battery assembly with high thermal conductivity
The invention relates to a battery assembly with high thermal conductivity. The battery assembly comprises a metal case having a hollow accommodation cavity formed therein, a plurality of battery cores installed parallel to one another within the metal case, and a common electrode for connection to the other electrode in each of the battery cores. Each of the battery cores has two electrodes, with one of the electrodes that corresponds to those of the rest of the battery cores being connected in a thermally conductive manner to the metal case. The invention takes advantage of high thermal conductivity of metallic material and dissipates heat by connecting the metal case to the battery electrodes. The invention further comprises fixation troughs formed on the metal case, thereby reducing the size of the assembly. |

Battery pack
In a battery pack according to the embodiment of the present invention, when coupling bosses of a second case are coupled to coupling holes of a first case, the first case and the second case can be easily coupled to each other by reducing the thicknesses of some portions of a rib having the coupling holes before the coupling bosses are coupled to the coupling holes. In addition, the first case and the second case can be smoothly coupled to each other at the initial step of coupling the coupling bosses and the coupling holes to each other by opening the outermost portion of the first case facing the top end of the rib having the coupling holes. |
