Abstract: A system is disclosed for protecting a network against malicious attacks or attempts for unauthorized access. A network is connected to an external network by a number of firewalls. Inspectors detect packets blocked by the firewalls and some or all of the packets are detected to a labyrinth configured to emulated an operational network and response to the packets in order to engage an attacker. Blocked packets may be detected by comparing packets entering and exiting a firewall. Packets for which a corresponding packets are not received within a transit delay may be identified as blocked. Entering and exiting packets may be compared by comparing only header information. A central module may receive information from the inspectors and generate statistical information and generate instructions for the inspectors, such as blacklists of addresses known to be used by attackers.

Abstract: A method and system for using a key lease in a secondary authentication protocol after a primary authentication protocol has been performed is described. In one embodiment, the primary authentication protocol comprises a strong, secure, computationally complex authentication protocol. Moreover, the secondary authentication protocol comprises a less complex (compared to the primary authentication protocol) and less secure (compared to the primary authentication protocol) authentication protocol which can be performed in a length of time that is shorter than a length of time required to perform the primary authentication protocol. In an embodiment, the key lease includes context information.

Abstract: In a computer network, a method of mutually authenticating a client device and a network interface, authenticating a user to the network and exchanging encryption keys. In one embodiment, the method comprises authenticating the client device at the local network device point, with which the client device exchanges an encryption key and then the user is authenticated by a central authentication server. In another embodiment, the method comprises authenticating the client device at the central authentication server, with which the client device exchanges a key which is passed to the network device with a secret shared between the central authentication server and the network device. In this embodiment, the user is also authenticated at the central authentication server.

Abstract: A design structure for a 3D chip having at least one I/O layer connected to other 3D chip layers by a vertical bus such that the I/O layer(s) may accommodate protection and off-chip device drive circuits, customization circuits, translation circuits, conversions circuits and/or built-in self-test circuits capable of comprehensive chip or wafer level testing wherein the I/O layers function as a testhead. Substitution of I/O circuits or structures may be performed using E-fuses or the like responsive to such testing.

Abstract: The invention relates to optoelectronic systems for detecting one or more target particles. The system includes a reaction chamber, a specimen collector, an optical detector, and a reservoir containing cells, each of the cells having receptors which are present on the surface of each cell and are specific for the target particle to be detected, where binding of the target particle to the receptors directly or indirectly activates a reporter molecule, thereby producing a measurable optical signal.

Abstract: A programmable link structure for use in three dimensional integration (3DI) semiconductor devices includes a via filled at least in part with a phase change material (PCM) and a heating device proximate the PCM. The heating device is configured to switch the conductivity of a transformable portion of the PCM between a lower resistance crystalline state and a higher resistance amorphous state. Thereby, the via defines a programmable link between an input connection located at one end thereof and an output connection located at another end thereof.

Abstract: A system (100) and method for managing fond raising activities by various types of organizations (210) through the promotion and sale of digital media content (160) is provided. Vouchers or media cards (152), for redemption of songs, videos, animation, games, etc., may be provided to non-profit organizations (210) or other organizations for subsequent sale to consumers (215) to raise monies associate with an event or promotion. The vouchers (152) may have an identifier that permits a consumer to redeem the voucher (152) either on-line (e.g., a web site) (140) or through in-store locations (145). The vouchers (152) may be tracked and accounted for along the process and checks are made to determine validity of a (voucher152) presented for redemption. When a valid voucher (152) is redeemed, a download of the associated digital media (160) may occur to a consumer's device (135). Accounting of fees received and paid to media providers and the organizations may also be provided.

Abstract: A method for preparing a nucleic acid component of a sample for amplification includes contacting the sample with a porous support that deactivates a nucleic acid amplification inhibitor component of the sample and directing a fluid through the porous support, whereby the nucleic acid component of the sample is directed through at least a portion of the porous support and is separated from the support, thereby preparing the nucleic acid component for amplification.

Abstract: The process begins with separate device wafers having complimentary chips. Thin metal capture pads, having a preferred thickness of about 10 microns so that substantial pressure may be applied during processing without damaging capture pads, are deposited on both device wafers, which are then tested and mapped for good chip sites. A handle wafer is attached to one device wafer, which can then be thinned to improve via etching and filling. Capture pads are removed and replaced after thinning. The device wafer with handle wafer is diced, and good chips with attached portions of the diced handle wafer are positioned and bonded to the good chip sites of the other device wafer, and the handle wafer portions are removed. The device wafer having known good 3-D chips then undergoes final processing.

Abstract: The present invention relates to a method for predicting an optimum transmission frame size in a wireless computer network. The method comprises assessing transmission channel quality in the network, calculating an optimum length for the transmission frame, adjusting the length of the transmission frame to the predicted optimum length, transmitting the frame at its adjusted length and assessing the quality of the transmission of the frame. Prediction of the optimum frame size employs a Kalman filter which employs the parameters of bit error rate and random processing noise in the calculation of the predicted optimum frame length.

Abstract: An intermodulation product reduction or cancellation amplifier received two input signals that are split in quadrature wherein the inphase outputs are summed and then amplified as an inphase signal, and the quadrature outputs are fixed-phase phase-shifted, then summed and then amplified as a quadrature signal. The inphase and quadrature signals are fed into an output hybrid for canceling intermodulation products, where the fixed-phase phase shift is +/?60° for reducing 3rd order, +/?36° for reducing 5th order, and +/?25.71° for reducing 7th order intermodulation products, for examples, for improved signal communications of the two signals over a common antenna or link.

The tee mount is affixed on one side outer surface of the crown to hold a tee. The marker holder is formed on the visor to hold a golf ball marker. The adjustable includes two ends to be mated together or releasable.

Abstract: The hybrid active combiner and circulators serves as a coupler and is a three port network that integrates a directional coupler topology with active devices placed in the coupling paths in order to synthesize a low-loss active combiner circuit or a circulator device with minimal insertion losses.
