Synthetic communication network method and system
Aspects of the present invention provide a method and system of registering a phone device on a synthetic communication network. One implementation receives a request to connect the phone device to a synthetic communication network that transmits messages over a data network using one or more phone numbers from a voice network.

Recording apparatus, recording method, and recording program, and image capturing apparatus, image capturing method and image capturing program
To improve user-friendliness in recording AV data created after recording is started until it is stopped as a file. AV data that are created after recording is started until it is stopped are recorded as a file. Information that represents a reproduction region and mark information that represents a jump position are additionally written to a reproduction list file. At this point, it is determined whether or not restrictions that have been set to the reproduction list file and an attribute file for additional writing are satisfied on the basis of the reproduction list file as an additionally writable candidate and the attribute file that correlates reproduction time and address of the AV data. When having been determined that they be satisfied, the reproduction region information and the mark information are additionally written to the reproduction list file as the additionally writable candidate. When having been determined that they be not satisfied, a new reproduction list file is created. As a result, the user can perform a recording operation for the AV data without necessity of recognizing the restrictions that have been set to the reproduction list file and the attribute file. |

Efficient collaging of a large image
Embodiments of the present invention relate to collaging image data to form a large image using high-performance computing in a parallel computing environment. The collaging of the image data includes performing an intra-node merge operation on image data such that the merged intra-node data is not written to the file system, but instead maintained in volatile processor memory.

Following the intra-node and inter-node merge operations, tiles representing the collaged image may be written to a file system memory for persistent storage. |

Radio communication system and transmitting apparatus used for the same
To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels. |

Ink-based layer fabrication using halftoning to control thickness
An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process. |

Calculation of the candidate graph crossing point total can be halted at the intermediate value.

The first and second radiating planes are parallel; the second radiating plane is positioned above the first from which it is electrically insulated and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is larger than the surface of the second radiating plane covering the conducting arms of the second pair of dipoles. The first radiating plane can be defined by a first pair of dual cross-polarization dipoles or one printed circuit dipole and the second radiating plane can be defined by a second pair of dipoles chosen from cross dipoles, butterfly dipoles and printed circuit dipoles. |

Ring dipole antenna
An antenna having a radiator comprising a conduct in a closed path driven by a plurality of microstrips connecting the radiator to a common, single feed and to a ground plane, with the radiator lying in a plane parallel to that of the ground plane. The radiator may be annular, with the feed located in its center. The relative location of the feed on the microstrips allows a lower input impedance to be leveraged to match a higher load impedance of the radiator. A single ended input drives all points of the radiator substantially in phase. In another embodiment, the antenna comprises a cylindrical choke one-quarter wavelength in length placed around the coax feed and connected to the underside of the ground plane. |
