System for eliminating unauthorized electronic mail
A system for eliminating unauthorized email sent to a user on a network employs an email-receiving server connected between the network and the user's email client for receiving email addressed to the user and rejecting those in which the sender address does not match any of sender addresses maintained on an “authorized senders” list (ASL list). The ASL lists are maintained by an ASL manager in an ASL database operable with a spam processor module. A redirector module rejects the email if, upon sending a request for validation to the spam processor module, the sender's address does not match any authorized sender address on the ASL list. Email rejected by the redirector module is redirected to a web-based messaging (WBM) module which sends a message to the sender to confirm that the sender is a legitimate sender of email to the intended recipient. If the sender logs on to confirm their status, the WBM module executes an interaction procedure which can only be performed by a human, in order to ensure that the confirmation procedure is not performed by a mechanical program. The ASL manager maintains the ASL lists based upon sender address data collected from various sources and analyses of various email usage factors, including sent email, received email, contact lists maintained by the user, user preference inputs, third party programs, etc. |

The TONID provides a fast-path that avoids protocol processing for most large multi-packet messages, greatly accelerating data communication. The TONID also assists the host for those message packets that are chosen for processing by host software layers. A communication control block for a message is defined that allows DMA controllers of the TONID to move data, free of headers, directly to or from a destination or source in the host. The context is stored in the TONID as a communication control block (CCB) that can be passed back to the host for message processing by the host. The TONID contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A preferred embodiment includes a trio of pipelined processors with separate processors devoted to transmit, receive and management processing, with full duplex communication for four fast Ethernet nodes. |

Rules-based transaction prefetching using connection end-point proxies
Network proxies reduce server latency in response to series of requests from client applications. Network proxies intercept messages clients and a server. Intercepted client requests are compared with rules. When client requests match a rule, additional request messages are forwarded to the server on behalf of a client application. In response to the additional request messages, the server provides corresponding response messages. A network proxy intercepts and caches the response messages. Subsequent client requests are intercepted by the network application proxy and compared with the cached messages. If a cached response message corresponds with a client request message, the response message is returned to the client application immediately instead of re-requesting the same information from the server. A server-side network proxy can compare client requests with the rules and send additional request messages. The corresponding response messages can be forwarded to a client-side network proxy for caching. |

The sheet is non-porous and may have a topical antiseptic on the side which is applied to the skin. A fluoroscope or roentgenographic image of the portion of the body to which the adherent film is applied will show the underlying skeletal and radiopaque elements as well as the overlying surgical grid. Once the targeting device is applied, the coordinates on the grid lines are clearly visible on the surface of the skin as well as on the fluoroscopic or radiographic image and by knowing the direction of the fluoroscopic or radiographic beam, the operator will be able to thereby correlate a specific locus on the skin with an underlying skeletal element or other underlying radiopaque structure. By applying the targeting device to the part of the body in a circumferential or nearly circumferential manner, and utilizing a radiolucent operating room table, and a radiograph or C-arm fluoroscope, targeting techniques using the targeting device can be utilized at surgery. Multiple targeting or percutaneous procedures can be performed at the same sitting with the application of a single device. |

The input M channel audio is provided to an analysis filter bank which converts the time domain signals into frequency domain signals. Relevant inter-channel spatial cues are extracted from the frequency domain signals on a sub-band basis and are used as parameters to generate adaptive N channel filters which control the spatial placement of a frequency band element in the up-mixed sound field. The N channel filters are smoothed across both time and frequency to limit filter variability which could cause annoying fluctuation effects. The smoothed N channel filters are then applied to adaptive combinations of the frequency domain input signals and are provided to a synthesis filter bank which generates the N channel time domain output signals. |

Tape failover across a cluster
A security appliance that encrypts and decrypts information is installed in each of redundant multi-paths between a host system and a back up tape storage system. The host system is arranged to detect failures in a primary path to the tape system being used. When the failure is detected, the host system enables transfers to the same tape system through an alternative path. Encryption keys and host/tape designators (identifiers) are broadcast among the security appliances in the alternative data paths. When the host system switches from the primary path to the secondary path, even though the secondary security appliance did not generate the encryption keys, the secondary path security appliance will have such keys and will properly encrypt and transfer data from the host to the tape system. The secondary will also properly retrieve encrypted data from the tape system, decrypt it and deliver it to the host. All of these operations will be transparent (invisible) to a running application in the host. |

Methods and apparatus for monitoring the integrity of a quantum channel supporting multi-quanta pulse transmission
A transmitter classifies quantum pulses into supervisory pulses and message pulses, and assigns each message pulse to a message bit. Each message pulse is then encoded using a coding base randomly selected from a set of coding bases, and with a polarity relative to the coding base that depends on the value of the corresponding message bit. Supervisory pulses are encoded using a coding base different from the coding bases in the aforementioned set. The encoded pulses are sent to a recipient over a quantum channel. The transmitter also informs the recipient of the positions of the supervisory pulses. The recipient detects the pulses relative to a locally selected coding base, producing a zero-click, a one-click or a two-click. By measuring the received proportion of zero-clicks, one-clicks and two-clicks, for both message pulses and supervisory pulses, and by verifying whether these detection statistics obey certain expected relationships, the recipient can determine whether an attack is taking place on the quantum channel. |

False channel detection for wireless communication
Techniques for detecting acquisition of a false channel in a wireless communication system are described. For false channel detection, a peak corresponding to a signal from a base station is initially detected. Frequency acquisition and time tracking of the peak are then performed. The frequency acquisition attempts to determine and correct downconversion frequency error. The time tracking attempts to follow the peak as it moves due to sample timing error and/or changes in channel conditions. Whether the signal is from a desired frequency channel or a false frequency channel is determined based on the time tracking. If a false channel is acquired, then the sampling timing will be either too slow or too fast, and the peak will move at a fast rate. A false channel may be detected based on the movement of the peak. |

Semiconductor magnetic memory integrating a magnetic tunneling junction above a floating-gate memory cell
A semiconductor magnetic memory device has a magnetic tunneling junction formed over a memory cell. The memory cell has a control gate surrounded by a floating gate. The floating gate is coupled to the magnetic tunneling junction through a pinning layer that maintains the magnetic orientation of the lower magnetic layer of the junction. A current through a selected word line, coupled to the control gate, generates a first magnetic field. A current through a cell select line generates a second magnetic field that is orthogonal to the first magnetic field. This changes the magnetic orientation of the upper magnetic layer of the junction to lower its resistance, thus allowing a write/erase voltage on a program/erase line to program/erase the floating gate. |
