Frame feeding system and frame feeding method
In recent years, frames have gotten larger in size and thinner, and warping of the frames has posed a problem. If a warp of a frame is large, there is a high possibility that fetching the frame may fail. If fetching the frame fails, that is, if the frame cannot be fetched, the lead time of mounting gets longer. Further, the frame that cannot be fetched has to be manually removed by an operator. Therefore, a man-hour increases. According to the present invention, before a loader feeder fetches a frame from a frame magazine, a loader lifter is moved in a Y direction. Thereafter, the loader feeder fetches the frame from the frame magazine. |

The BTS may control when and how the sounding signals are sent by the CS. This helps reduce the possibility of adjustment signals transmitted by two or more CSs colliding. Thus, sounding signals transmitted by the CS in response to a request by the BTS can be received by the BTS with higher a probability of success. This permits the BTS to more accurately characterize the channel and to provide better adjustment of power level, frequency offset, and/or timing offset for more optimal communication. Such techniques can be used to reduce bit error rates and to improve the overall signal to noise ratio encountered by the system. |

As the scale measure, the variance of the filter linearly relates to the noise standard deviation of a predetermined noise model in the new filtering method. The new filter has only one optional parameter that remains stable once tuned. Although single-pass processing using the new filter generally achieves desired results, iterations are optionally performed. |

A node of the ring broadcasts a message carrying the MAC address group indexed by its own MAC address in the Ethernet ring network; the node of the ring receiving the message completes the classification of the MAC address corresponding to the ring port in its own FDB by adding the MAC address group carried by the message into its own FDB. The present invention also provides a device for classifying media access control (MAC) address based on Ethernet ring network. With the method and device of the present invention, the MAC address refreshing time of a node of the ring is shortened, and the convergence speed of protection switching is improved. |

Scattered pilot pattern and channel estimation method for MIMO-OFDM systems
A method and apparatus are provided for reducing the number of pilot symbols within a MIMO-OFDM communication system, and for improving channel estimation within such a system. For each transmitting antenna in an OFDM transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna. The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain. |

Method and system for compromise greenfield preambles for 802.11N
Aspects of the invention described herein may enable a greenfield access mode in IEEE 802.11n WLAN systems in comparison to an alternative approach that may not provide greenfield access. The utilization of greenfield access may reduce the portion of time required to transmit data due to overhead comprising preamble fields and header fields. This may enable higher data throughput rates to be achieved. This may further enable more robust transmission of data by enabling comparable data rates to be maintained while reducing the coding rate of encoded transmitted data. The reduction of the coding rate may enable comparable data rates to be maintained for transmission via RF channels characterized by lower SNR while still achieving desired target levels of packet error rates. In another aspect of the invention, mixed mode access may be achieved while reducing the portion of time required for transmitting data due to overhead. |

Systems and methods for signal acquisition using predicted environmental context
This disclosure involves methods and systems for a GNSS receiver to ascertain its environmental context and subsequently adjust the signal processing and search algorithms to provide improved acquisition. A rapid pre-scan is performed to determine the presence of relatively strong signals. If no satellites are found in the initial pre-scan, successively more sensitive searches are conducted until at least one satellite is acquired. The information from these pre-scans is used to predict the environmental context of the receiver and correspondingly tailor the parameters for the remaining search operations. |

Device for and method of repelling animals
A weather-resistant housing (1 a, 1 b) provides a chamber (1 b) containing an acoustic generator. An acoustic outlet (2) is located, in use, to direct an acoustic signal into air of the animal tunnel/burrow system rather than into ground/soil. The acoustic outlet may be an acoustic tube that extends along a tunnel of a subterranean tunnel system of the species to be deterred so as to form part of that tunnel. The device may be powered by a battery (10). A part of the device that extends above the ground may support a solar panel (5). The acoustic signal represents one or more deterrent communication calls of the species to be deterred. In the case of a water vole or mole, the acoustic signal represents one or more of a distance regulating or territorial call and a defensive call. Two such communication calls may be artificially paired to form the acoustic signal. |

memories and methods for repair in open digit memory architectures
A memory with extra digit lines in full size end arrays with an open digit architecture, which can use the extra digit lines to form repair cells. In one example, folded digit sense amplifiers are connected to an end array with an open digit architecture such that each sense amplifier corresponds to a group of four digit lines. Two digit lines of the group connect to two open digit sense amplifiers and the other two digit lines connect to the corresponding folded digit sense amplifier. A repair method can be performed on memories including the end arrays with folded digit sense amplifiers. A row in a core array including a replaceable IO is activated and a row in an end array is activated. The repair cells in the end array can be sensed by the folded digit sense amplifiers to generate a replacement IO, which is selected rather than the replaceable IO. |
