Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to classify a sample as clean or malicious. An example apparatus includes instruction identifies circuitry to convert a sample into a sequence of instructions, abstract language circuitry to transform the sequence of instructions into an abstract language representation, transition matrix circuitry to create a Markov transition matrix, the Markov transition matrix to represent transitions within the abstract language representation, and classifier circuitry to classify an unknown sample as clean or malicious, the classification in response to whether the Markov transition matrix is closer to a clean group of Markov transition matrices or a malicious group of Markov transition matrices.

Abstract: The present techniques relate to a microchanneled solid electrolyte (MSE), an electrolyzer and a method including or using the MSE for in-situ regeneration and collection of CO2 during a CO2 electroreduction operation. The MSE includes an anion conducting layer configured to conduct (bi) carbonate anions from a surface of an adjacent cathode; a cation conducting layer configured to conduct protons from a surface of an adjacent anode; and an integrated channel layer comprising multiple microchannels formed between the anion conducting layer and the cation conducting layer. The microchannels define a hollow path extending across the integrated channel layer for receiving the (bi) carbonate anions from the anion conducting layer and the protons from the cation conducting layer, thereby locally regenerating and collecting CO2 along and within the microchannels.

Abstract: A rail vehicle has a carbody shell having an end wall and a usable space. The end wall includes a doorway for providing access to the usable space, and at least two footplate catchers for preventing a set of footplates arranged adjacent to the footplate catcher from entering the usable space, such as in an event of a crash.

Abstract: A multiple-layer gas diffusion electrode for sustaining electrochemical reduction of gaseous CO2 and/or CO into multi-carbon products is provided, including a gas diffusion layer comprising a support layer, a microporous layer having pores that are sized to maintain the gaseous CO2 and/or CO, or a combination thereof available for electroreduction, and a catalytic layer comprising a catalyst favoring reduction of the CO2 and/or CO. There are also provided, a method for producing the gas diffusion electrode, a spacer being positionable between an ion exchange membrane and an anode of a membrane electrode assembly, a reactor including a membrane electrode assembly and a support structure, a stack reactor that can include the gas diffusion electrode and the spacer as described herein, a method to diagnose and isolate at least one faulty repeat cell unit in an electrolyzer stack reactor, and a rinsing method for facilitating operation of an electroreduction system.

Abstract: The present disclosure is directed to composite focal plane array (CFPA) imaging systems with techniques and architectures for efficient video data processing and providing video products from such systems.

Abstract: The present disclosure is directed to composite focal plane array (CFPA) imaging systems and techniques for calibrating such imaging systems. An unmanned aerial vehicle has a CFPA imaging system including a plurality of lens assemblies, a plurality focal plane array (FPA) sensors disposed on a planar substrate, and an image processing module. A first processing node of the module receives overlapping image data from the sensors and generates an update for a sensor calibration model based on key points in the overlapping image data. A plurality of other processing nodes receives image data from the sensors. The sensor calibration model is applied to correct the image data, thereby compiling a composite image.

Abstract: Pairing of an external device using a random user action is disclosed herein. An example method includes restricting the external device from accessing a resource. A user input receivable from the external device is identified based on a type of the external device, the user input not included in a list of previously generated user actions. In response to receipt of the user input from the external device within a threshold time period, the external device is authorized to access the resource.

Abstract: A needle electrode fixation device is configured to secure a transdermal needle electrode to a patient. The device includes a base having a body that defines a first portion and a second portion. The first and second portions are rotatable relative to each other. The first portion defines a channel configured to fit a portion of the transdermal needle electrode. The second portion defines a recess configured to fit a tip of the needle electrode. The device further includes an adhesive layer configured to affix the base to the patient.

Abstract: An anti-rattle hitch device is described. A rotating barrel pin is positioned proximate to the normal accessory port of receiving hitch housing. The pin cooperates with resilient bushings that are engineered to compress in overload situations, while urging the accessory drawbar flush against the upper, inner facing of the housing when the device is engaged under normal conditions. The resulting apparatus prevents unwanted rattling and play of the hitch and accessory without the need for loose or removable parts.
