Malicious e-mail attack inversion filter
A malicious e-mail manager provides protection from malicious e-mail attacks. A malicious e-mail manager examines an e-mail stream, and identifies suspicious e-mail messages therein. The malicious e-mail manager inverts responses to addresses from which identified suspicious e-mail originated. Where the target address of a suspicious e-mail message points to an existing recipient, the malicious e-mail manager returns an error code to the originating address indicating that the recipient does not exist. On the other hand, where the target address of a suspicious e-mail message points to a non-existent recipient, the malicious email manager returns a success code to the originating address, indicating that the e-mail message was delivered. Thus, senders of malicious e-mail believe that existing users are non-existent and vice versa. E-mail from legitimate senders is handled normally. |

System for power savings in server farms
A threshold-based approach is used to assign tasks to servers in a server farm. A “number of connections” count or “connection rate” is maintained for an active server and when the count achieves a first value a wake up signal is sent to a next (inactive) server to alert the inactive server to become active and periodic keep alive signals are initiated. When the number of connections next reaches a second, higher value, subsequent requests for connections are sent to the newly active server. Variations of this approach allow for servers and their associated processes and devices to be handled in clusters for power management scaling efficiency. Servers can be placed in the inactive mode when the number of connections reaches a lower threshold. Other criteria can be used to determine activation of servers, processors or other devices or processes. Other types of resource use monitoring can also be used with this invention. |

To increase throughput efficiency and attain a higher achieved bit rate for data transmissions over a high speed shared channel, a variable transmit power increase factor is used to control the maximum rate at which the power at which data is transmitted over the high speed shared channel can increase. In one non-limiting implementation, the power increase factor F is varied with the current total downlink transmitted power available for high speed downlink transmission. For example, when the available high speed shared channel power is large, the variable transmit power increase factor assumes a more conservative value, e.g., a smaller F value, at the beginning of the high speed downlink transmission, and then a more liberal value, e.g., a larger F value, later during the high speed downlink transmission. |

Adaptive channel quality estimation algorithm to support link adaptation
RF communications received by a wireless terminal from a servicing base station are used to determine the channel quality such as reported bit error probability (BEP). The RF communications may be in the form of RF bursts that are part of a data frame. An estimated BEP may be determined from the signal to noise ratio (SNR) of the RF bursts and or a sequence of soft decisions extracted from the RF bursts, and their historical performance. The SNR maps to an estimated BEP based upon the modulation format of the RF bursts. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). The reported BEP may be based upon the estimated BEP, RBER, and/or RBER threshold. The RBER threshold may be adaptively incremented or decremented depending upon whether or not the RF communications were properly decoded. The size of the increment or decrement may be based on the channel quality. |

Dial-out with dynamic IP address assignment
Packet network addresses, such as Internet Protocol addresses, may be assigned dynamically to computer systems accessed from the packet network by dial-out calls through a telephone network. A dial-out destination system will have an assigned name, typically a domain name. In response to a request for translation of the name, a network access server capable of reaching the destination obtains or assigns an address on a temporary basis. The network access server initiates the call to the destination system through the telephone network. The system initiating communication to the destination system uses the assigned address in any subsequent packet data communications. When the communication ends, the address is again available for a new assignment. This approach provides a dynamic address assignment technique for use on dial-out access services. |

Image processing apparatus, an image processing method, a medium on which an image processing control program is recorded, an image evaluation device, an image evaluation method and a medium on which an image evaluation program is recorded
In image processing according to the prior art, the important part of photographic image data (referred to herein as the object) could not be determined and therefore required human participation.A computer 21 which is the core of image processing calculates an edginess which is an image variation from a differential value of data for adjacent picture elements in a step SA110, and determines object picture elements by selecting only images with a large variation in steps SA120, SA130. As optimum parameters for contrast correction and lightness compensation are calculated from image data for object picture elements in steps SA310-SA330, image processing indicators based on object picture elements are determined, and optimum image processing can be performed automatically. After summing a luminance distribution for each area of the image, which is a feature amount, while uniformly selecting picture elements in a step SB110, a reevaluation is performed by a weighting determined for each area in a step SB120, and a luminance distribution strongly influenced by the luminance distribution of the photographed object is thus obtained with uniform sampling. After determining the intensity of this luminance distribution insteps SB130-SB150, the image data is converted in a step SB160, and image processing can therefore be performed with optimum intensity while reducing the processing amount. |

Picture color tone controlling method and apparatus
In a picture color tone control method and apparatus for a printing press, in order to make it possible to use an IRGB densitometer to perform color tone control even when printing is performed with a density which exceeds an estimated maximum color space, a target color mixture halftone density for each ink supplying unit width when a printing picture is divided with an ink supplying unit width of ink supplying apparatus 6, 7 is set, and an actual color mixture halftone density for each ink supplying unit width of an actually printed sheet obtained by printing is measured using an IRGB densitometer 1. The color mixture halftone densities are individually converted into tone values. Thereupon, for the conversion into actual tone values, the publicly known Neugebauer expression wherein the Yule-Nielsen coefficient n is set to such a value that the tone values and the color mixture halftone density value have a substantially linear relationship to each other is used. Further, the tone values are converted into a monochromatic halftone density, and a solid density difference corresponding to the difference between the target monochromatic halftone density and an actual monochromatic halftone density is determined using the Yule-Nielsen expression or the like. Then, the ink supplying amount is adjusted for each ink supplying unit width in response to the solid density difference. |

Color conversion method and profile generation method
A tincture adjustment value used to adjust a monochrome signal to a tincture desired by a user is set, and a tincture conversion table and chromaticity line table are generated based on that tincture adjustment value and the profile of an image output apparatus. Using the generated tables, a lightness signal L* corresponding to an input monochrome signal is converted into a distance signal l on a chromaticity line, and the distance signal l is converted into a chromaticity signal (a*, b*). The lightness signal L* and chromaticity signal (a*, b*) are converted into a color signal of the image output apparatus. |
