Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.

Abstract: A method comprising: sampling a temporal causal graph from a temporal graph distribution specifying probabilities of directed causal edges between different variables of a feature vector at a present time step, and from one variable at a preceding time step to another variables at the present time step. Based on this there are identified: a present parent which is a cause of the selected variable in the present time step, and a preceding parent which is a cause of the selected variable from the preceding time step. The method then comprises: inputting a value of each identified present and preceding parent into a respective encoder, resulting in a respective embedding of each of the present and preceding parents; combining the embeddings of the present and preceding parents, resulting in a combined embedding; inputting the combined embedding into a decoder, resulting in a reconstructed value of the selected variable.

Abstract: Techniques are described for improving real-time application protection (RTAP) systems (e.g., web application firewalls (WAFs), runtime application self-protection (RASP) systems). In particular, a device within a trusted network may monitor or test the configuration settings of the RTAP systems, network traffic into the RTAP systems, and/or log information from the RTAP systems. For example, the device may detect drift in a configuration for a particular RTAP system by comparing the configuration settings of the RTAP systems to baseline configuration settings and classifying any detected drift as good drift or bad drift. In some examples, the device may maintain the configuration settings or set the configuration settings as the baseline configuration settings when the configurations settings include good drift from the baseline configuration settings. In other examples, the device may set the configuration settings with the bad drift to the baseline configuration settings.

Abstract: A system having components coupled to an aircraft that measure the navigational state and state uncertainty of an aircraft. To do so, the aircraft captures an image of its surrounding environment including an object of interest and applies one or more machine vision models to the image. One or more of the models determine if the image is acceptable, in that it determines if an object of interest is represented in the image. One or more of the models determine a calibrated uncertainty based on information extracted previously labelled images and current measurements of navigational state and uncertainty. One or more of the models determine a protection level for the aircraft and determines an operational system of the aircraft is available to perform a navigational action based on the protection level (e.g., by comparing protection level to an alert level).

Abstract: A data storage library is described that protects against a malware attack by providing a scheduled write window of time where archive data can be written to tape cartridges in the tape library on behalf of a client. At times outside of the write window, the tape library is disabled from writing any archive data to any of the tape cartridges in the tape library. Accordingly, the tape library is protected from a malicious entity attempting to download malware to tape cartridges in the tape library outside of the designated write windows. The tape library is configured to provide or otherwise read archived data from a tape cartridge both in the write window and outside of the write window.
