Abstract: A computer implemented method and system for protecting against denial of service attacks by detecting changes in a preferred set of hierarchically-structured items in a network data stream in which a set of network destination prefixes is identified that account for a user specified target of the attack traffic. Changes in the attack traffic profile are detected and new sets of network destination prefixes are generated when the attack has shifted by a predetermined threshold. sets of identified destination prefixes are then translated into route announcements to divert attack traffic to mitigation devices.

Abstract: A method for reviewing content previously displayed on a display screen includes capturing at least one screenshot of at least part of a display screen in response to an occurrence of a trigger event based on a change in displayed content. A value of at least one criterion of the displayed content is stored in association with each captured screenshot. A request is received, based on at least one of the stored criteria, to review a captured screenshot. A screenshot corresponding with the request may be superimposed on the display screen as an overlay. Content displayed on the screen for the occurrence of the trigger event is monitored. A screenshot in response to each occurrence of the trigger event is captured. The request to review a screenshot may be a request to review a selection from a plurality of captured screenshots.

Abstract: The inventors have unexpectedly discovered that shock and/or potential multi-organ failure due to shock can be effectively treated by administration of liquid high-dose protease inhibitor formulations to a location upstream of where pancreatic proteases are introduced into the gastrointestinal tract. Most preferably, administration is directly to the stomach, for example, via nasogastric tube under a protocol effective to treat shock by such administration without the need of providing significant quantities of the protease inhibitor to the jejunum and/or ileum.

Abstract: A multi-element fiber scanner for scanning electromagnetic imaging radiation includes a base having a base plane and a longitudinal axis orthogonal to the base plane and a fiber link passing through the base in a direction parallel to the longitudinal axis. The fiber link is operatively coupled to at least one electromagnetic radiation source. The multi-element fiber scanner also includes a retention collar disposed a predetermined distance along the longitudinal axis from the base and a first set and a second set of piezoelectric tubes. First and second piezoelectric tubes of the first set are joined to the base and extends from the base and first and second piezoelectric tubes of the second set are joined to the retention collar and extend from the retention collar.

Abstract: A valvetrain for an internal combustion engine includes a camshaft and a rocker arm assembly. The rocker arm assembly includes an electrical device, a rocker arm, and a cam follower. A contact held to the rocker arm abuts a spring attached to a component distinct from the rocker arm assembly to form an interface. The electrical device is powered through the interface. The spring slides over the contact as the rocker arm assembly pivots to actuate a moveable valve. The interface is formed near a pivot axis whereby the motion undergone by the interface is much less than the motion undergone by points on the rocker arm assembly more distal from the axis. Keeping the interface proximate the pivot axis and leaving the spring free to slide over the contact reducing the extent to which the spring undergoes movement and wear during valvetrain operation.

Abstract: A bicycle saddle comprising a base, a rear portion positioned on the base, and a front portion positioned on the base. The rear portion supports the sit bones of the rider and includes a first resilient material having a first hardness (e.g., 45-55 Shore C), and the front portion supports the genitalia of the rider and includes a second resilient material having a second hardness (e.g., 35-45 Shore C) less than the first hardness. The front portion includes side portions having a first thickness above a highest part of the side sections, and the side portions are separated by a central portion having a second thickness less than the first thickness. Preferably, a lower surface of the central portion is substantially unsupported to form a trampoline-like structure. The upper surface of the central portion can include memory foam and is substantially flush with upper surfaces of the side portions.

Abstract: A Secure Telephony Identity (STI) proxy server is described for intercepting incoming Voice over Internet Protocol (VoIP) communication requests for the purpose of mitigating an effect of fraudulent and nuisance VoIP communications. The STI proxy server may facilitate an STI verification server in verifying an authenticity of an originating network associated with an incoming call request. In one example, the STI proxy server may verify that the visited network is permitted to interact with the home network, based on a list of permissible networks. In addition, the STI proxy server may determine whether public STI certificates associated with an originating network have expired or set to expire within a predetermined time interval. In response to an actual o impending expiration, the STI proxy server may facilitate retrieval of a superseding, new public STI certificate for use by an STI authentication server to digitally sign an outgoing SIP INVITE messages.

Abstract: This document describes systems and method of embedded printing for additive manufacturing. A print material is printed into a support material. The print material and the support material each have a fluid phase and a solid phase. The print material transitions from the fluid phase to the solid phase based on a fluid-fluid interaction with the support material. One or more parameters of the support material can be adjusted to cause a diffusion rate of the print material into the support material during the fluid-fluid interaction to be less than a threshold value. Multiple print materials can be printed into the support material simultaneously.
