Abstract: A compute instance stores a programmable feature extractor associated with a machine learning model maintained by a server-based computing system configured to communicate with the compute instance by way of a network. The machine learning model is based on a feature set that includes a plurality of features. The compute instance executes the programmable feature extractor to generate a feature vector corresponding to a data instance accessed by the compute instance, where the feature vector includes a feature value specific to the data instance for each feature included in the feature set. The compute instance transmits the feature vector corresponding to the data instance to the server-based computing system for use as a training input to the machine learning model.

Abstract: A fluid spray system is disclosed, featuring a modular design with interchangeable components. The system includes multiple inlet, outlet, and valve blocks, each with distinct configurations, allowing for customizable fluid flow paths. The valve blocks contain actuators that selectively connect the inlet and outlet blocks via tubes, facilitating fluid transfer. The sprayer housing, which houses the valve block, has an inlet and outlet opening for the inlet and outlet blocks, and includes a handle portion with a hollow handle guard. The system allows for precise control of fluid flow through separate inlet and outlet tubes positioned within the housing. The design includes safety features such as a safety selector to prevent accidental operation and trigger placement for ease of use. The system's modularity enables flexibility for different spraying applications, making it suitable for a wide range of fluid dispensing needs.

Some embodiments provide systems and methods for designing, building and using ultrasound probes having continuous arrays of ultrasound transducers which may have a substantially continuous concave curved shape in two or three dimensions (i.e., concave relative to an object to be imaged). Other embodiments herein provide systems and methods for designing, building and using ultrasound imaging probes having other unique configurations, such as adjustable probes and probes with variable configurations.

Abstract: An automated system attempts to characterize code as safe or unsafe. For intermediate code samples not placed with sufficient confidence in either category, human-readable analysis is automatically generated to assist a human reviewer in reaching a final disposition. For example, a random forest over human-interpretable features may be created and used to identify suspicious features in a manner that is understandable to, and actionable by, a human reviewer. Similarly, a k-nearest neighbor algorithm may be used to identify similar samples of known safe and unsafe code based on a model for, e.g., a file path, a URL, an executable, and so forth. Similar code may then be displayed (with other information) to a user for evaluation in a user interface. This comparative information can improve the speed and accuracy of human interventions by providing richer context for human review of potential threats.

Abstract: A fixation component includes tines extending from a base portion of the fixation component. Each tine is elastically deformable between a pre-set position and an open position. Each tine includes a hook segment extending from a proximal end near the base portion to a distal end. Each tine also includes a distal segment extending from the distal end of the hook segment to a tissue-piercing tip. When positioned in the pre-set position, the hook segment extends along a pre-set curvature that encloses an angle between 135 degrees and 270 degrees, and the distal segment extends away from a longitudinal axis of the fixation component.

Abstract: A system is provided for carbon dioxide (CO2) emission recovery. The system includes a methanization reactor. The methanization reactor is configured to receive CO2 separated from one or more off gases of a brake manufacturing process, receive hydrogen (H2) produced from an electrolysis process, convert the CO2 and the H2 via methanization reaction to produce methane (CH4), and supply the produced CH4 to at least one of a carbon/carbon (C/C) preform production process or another system for heat generation.

The system includes a reformer configured to convert an input into hydrogen and carbon monoxide and a methanization reactor coupled to the reformer. The methanization reactor is configured to receive carbon dioxide from one or more off gases of a carbon/carbon (C/C) preform production process, receive the hydrogen and the carbon monoxide from the reformer, convert the hydrogen, the carbon monoxide, and the carbon dioxide via methanization to produce methane, and supply the produced methane to at least one of the C/C preform production process or another system for heat generation.

Abstract: Changes in tissue stiffness have long been associated with disease. Systems and methods for determining the stiffness of tissues using ultrasonography may include a device for inducing a propagating shear wave in tissue and tracking the speed of propagation, which is directly related to tissue stiffness and density. The speed of a propagating shear wave may be detected by imaging a tissue at a high frame rate and detecting the propagating wave as a perturbance in successive image frames relative to a baseline image of the tissue in an undisturbed state. In some embodiments, sufficiently high frame rates may be achieved by using a ping-based ultrasound imaging technique in which unfocused omni-directional pings are transmitted (in an imaging plane or in a hemisphere) into a region of interest. Receiving echoes of the omnidirectional pings with multiple receive apertures allows for substantially improved lateral resolution.

Abstract: Possible Denial of Service (DOS) activity is detected and remediated based on an initial heartbeat failure from a network asset, followed by externally directed network traffic from the network asset. In general, an interruption of the heartbeat can signal the possible presence of malware on the network asset, and the externally directed network traffic, and particularly certain patterns of traffic such as a high volume of traffic toward an address with a known, good reputation, can signal the possible presence of a DoS bot on the network asset that is sourcing the network traffic.

Abstract: Various forms of anti-clog suction tips apparatus are disclosed. An exemplary anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.

Abstract: Systems and methods for ionizing analytes in a sample use an atomizer that generates aerosol particles containing the sample analytes and an emitter having inner and outer capillaries. The outer capillary is arranged about (e.g., concentrically about) the inner capillary, forms an orifice of the emitter, and receives the aerosol from the atomizer. The aerosol particles condense against the inner surface of the outer capillary and/or the outer surface of the inner capillary and form a reservoir of condensate liquid sample at the orifice of the emitter. The emitter receives, within the inner capillary, a nebulizing gas that flows towards the terminal end of the inner capillary. An electrical potential is applied between the emitter and an inlet of a sample analyzer. The nebulizing gas, the supply pressure of the aerosol to the outer capillary, and the electrical potential generate an electrospray plume of electrically charged analyte particles for analysis.

Abstract: A fast pyrolysis heat exchanger system for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As a granular solid heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials.
