Systems and methods for creating virtual universal plug-and-play systems
Methods and devices enable a device located on a source network to appear as a virtual device on a target network. Agent applications running on computers on the source and target networks communicate over a peer-to-peer network enabled by a super-peer networking server on the Internet. To share a device, the target network agent requests the source network agent to provide access to a device in the source network. The source network agent sends the device name, properties, and service template information to the target network agent. The target network agent uses the received information to announce itself as the device to the target network. Devices on the target network may request device services from the target network agent. Such requests are repackaged by the target network agent and sent to the source network agent. The source network agent redirects the service request to the actual device and redirects received responses to the target network agent. The target network agent receives the processes forwards service response to the requesting device. Thereafter, the requesting device on the first network can directly access services from the device on the second network as if the two devices were on the same network. Using such methods, devices on a local network may access services available on an Internet server as if the server was on the local network. |

In general, an OFDM transmitter operates to insert pilot symbols into a resource of a transmit frame according to a predetermined staggered pilot symbol pattern defining pilot symbol locations within the resource of the transmit frame. The predetermined pilot symbol pattern is defined such that pilot symbols are located at or near time boundaries of the resource, at or near frequency boundaries of the resource, or both. By doing so, when generating a channel estimate for the communication channel between the OFDM transmitter and an OFDM receiver based on the pilot symbols, extrapolations needed to estimate the channel near the boundaries of the resource are optimized, thereby improving overall channel estimation accuracy. |

The assembly further includes a rectangular second transducer configured to produce a second beam defining a fan-shape and extending generally in a second plane. The first transducer and the second transducer are oriented such that the respective first and second beams insonify different first and second areas each extending laterally with respect to a running direction of the surface watercraft, and such that the first beam is outside of the second plane of the second beam, the resulting planar separation of the first and second planes of the first and second beams reducing interference between the first and second transducers. |

Semiconductor memory device
A driver circuit having a redundant control function to store address data of a defective memory cell is provided to compensate a defect of a memory cell array. In other words, address data of a defective memory cell is stored not by using part of the memory cell array, but by using a non-volatile memory, which is provided in a memory controller, to store address data of a defective memory cell. The memory controller storing the address data of a defective memory cell contributes an increase in process speed, because it is not necessary to access the memory cell array in order to obtain the address data of the defective memory cell. |

Semiconductor memory including program circuit of nonvolatile memory cells and system
A semiconductor memory includes a plurality of nonvolatile memory cells arranged in a matrix and coupled to control gate lines, selection gate lines, bit lines, and source lines, and includes a source line control unit. The source line control unit, at a time of program operation, sets one of the source lines coupled to a row of the memory cells including a program memory cell to a high level voltage, and sets at least one of the remaining source lines coupled to a row of a non-program memory cells to be higher than a low level voltage of the selection gate lines and to be lower than the high level voltage of an unselection bit line. Thereby, a leak current lowering a voltage of the source lines at the time of program operation can be blocked off, and a program operation time may be shortened. |
