Abstract: A filter assembly for filtering a flow of incoming air entering a pressurized breathing gas system includes a filter housing and a filter media. The filter media includes a filtering section and a non-filtering section. The filter housing is structured to be inserted within a pressure generating device used in the pressurized breathing gas system. The filtering section is disposed within the filter housing and is structured to filter contaminant matter from the flow of incoming air. The non-filtering section is disposed outside of the housing and is structured to be separated from the filtering section so as to not make contact with the flow of incoming air. The filtering section and the non-filtering section are structured to be visually compared to one another such that a contaminant matter saturation level of the filter media can be determined.

Abstract: A method for machine learning based ultrasound image reconstruction can include receiving, at a reconstruction engine, imaging data; generating an initial estimate for a transmission image via a neural network trained (machine or self-learning) on paired transmission ultrasound and reflection ultrasound data; and performing image reconstruction using the initial estimate to generate transmission ultrasound images. The image reconstruction can generate higher quality transmission ultrasound when carried out by using the initial estimate as the starting point for iterative image reconstruction and using transmission data obtained via conventional transmission ultrasound frequencies (e.g. from 0.8 MHz to 1.5 MHz).

Abstract: The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.
