The message delivery systems allow messages to be delivered to any “Who, What, When, Where” from any “Who, What, When, Where” upon the detection of an occurrence of one or more “Who, What, When, Where” delivery conditions. A message (which may be any data object including text-based messages, audio-based message such as voicemail or other audio such as music or video-based prerecorded messages) is delivered in accordance with delivery conditions based on any available data, including topical, spatial, temporal, and/or social data. Furthermore, because the systems coordinate delivery of messages via multiple communication channels and through multiple devices, the communication channel for delivery of a message may be dynamically determined based on the delivery conditions. |

Communication management system
A communication management system manages the exchange of messages between devices using different communication networks and/or protocols. A sender device may transmit a message (e.g., a short message service “SMS” message) to a destination associated with a traditional “landline” phone number.

The communication management system can receive the message via the phone network, process the message, and provide the message to one or more electronic devices over a packet switched network, such as a local area network or the Internet. The electronic devices may use chat-based application software to process and display the message, provide robust message handline functionality, and facilitate responses to the message. |

Tiered priority system and callout performance booster
A method, computer program product and system uses a tiered priority system having three types of callout messages for use by a transaction processing system: (i) callout with a reserved path; (ii) callout with priority; and (iii) default priority callout with sharing mode. An online transaction program (OTP) issues a “reserve call” associated with a “callout with a reserved path”. In response, a reserve call processor initiates an asynchronous request to build an express socket path, and returns a special dispatchable unit of work identifier (special DUOW ID). The OTP subsequently issues any number of callouts to be sent on the express socket path using the special DUOW ID. A callout with priority dynamically allocates a path for sending a callout message, without queuing. A sharing mode combines a group of callout messages (types (i), (ii), and/or (iii) above) into a single TCP/IP send without queuing. |

Coordinates are generated for a reference point obtained by scrambling and mapping a symbol number not a symbol reference point position.

The calculated bit likelihood is then deinterleaved and subjected to SISO error-correcting decoding. The thus obtained bit likelihood is then reinterleaved and used to calculate a symbol probability. Soft symbols are generated through the multiplication of all the calculated symbol probabilities by corresponding reference points output by a second mapping unit similar to the first mapping unit. |

Solar cell, method for manufacturing solar cell, and solar cell module
A solar cell is provided with: a semiconductor substrate having a light-receiving surface and a non-light-receiving surface; a PN junction section formed on the semiconductor substrate; a passivation layer formed on the light-receiving surface and/or the non-light-receiving surface; and power extraction electrodes formed on the light-receiving surface and the non-light-receiving surface.

As a result of forming a aluminum oxide film having a predetermined thickness on the surface of the substrate, it is possible to achieve excellent passivation performance and excellent electrical contact between silicon and the electrode by merely firing the conductive paste, which is conventional technology. Furthermore, an annealing step, which has been necessary to achieve the passivation effects of the aluminum oxide film in the past, can be eliminated, thus dramatically reducing costs. |
