Abstract: A radiation reduction system that includes a computer and an imaging device configured to provide an image of a subject during a medical procedure using electromagnetic radiation. A variety of inputs are accepted from the medical practitioner using the computer such as subject body type, weight, and the like. These user inputs are used by the computer to determine operating settings that are transmitted to the imaging device either manually, a wired connection or wirelessly. The calculated settings are useful to generate one or more medically useful images of the subject while significantly reducing the overall radiation exposure to the subject and/or the personnel and/or medical practitioner.

Abstract: Methods, systems, and apparatuses are described herein for using processes and machine learning techniques to optimize medical imaging processes to reduce inadvertent exposure to harmful radiation. A machine learning model may be trained to output recommended medical imaging device operating parameter settings. Available operating parameters of a medical imaging device may be determined, and patient data may be received. The patient data and the available operating parameters may be used as input to the trained machine learning model, which might output recommended operating parameter settings. In turn, this output in addition to other calculations might be used to transmit, to the medical imaging device, data that causes modification of the operating parameters of the medical imaging device. Metadata corresponding to one or more images captured by the medical imaging device may be received, and the trained machine learning model might be further trained based on that metadata.

Abstract: A method of detecting urea-derived deposits in the exhaust line of an internal combustion engine having an SCR (selective catalyst reduction) aftertreatment system. A radio frequency (RF) transmitter is placed upstream of the SCR system's urea injector, and an RF receiver is placed downstream of the mixer. The transmitter and receiver are used to acquire baseline RF data representing a clean condition exhaust line without deposits. During subsequent operation of the engine, the transmitter and receiver are used to acquire subsequent RF data, which is compared to the baseline data after being corrected for temperature differences. If the comparison indicates the presence of one or more deposits, an alert signal is generated.

Abstract: A method and system for treating exhaust emitted via an exhaust line from a diesel engine. A POC system is installed on the exhaust line, and has at least one diesel oxidation catalyst (DOC), a set of two or more particulate oxidation catalyst (POC) elements, a first differential pressure sensor (?P1) to measure the pressure difference across the first and all but the last POC elements, and a second differential pressure sensor (?P2) to measure pressure differences across the last POC element. During operation of the engine, ?P1 is monitored to determine whether its POC elements require active regeneration, and ?P2 is separately monitored to determine whether its (the last) POC element requires active regeneration.

Abstract: An exhaust gas emissions aftertreatment system for spark-ignition engines, which simultaneously reduces the particulate matter, HC, CO, and NOx content of the exhaust. Various embodiments of the system have both a closely-coupled TWC device, and an under-floor treatment device. The under-floor device has either TWC or NOx reduction functionality, depending on whether the engine is run under stiochiometric or lean burn operating conditions.

Abstract: A wall-flow exhaust gas emissions aftertreatment device for simultaneously reducing the particulate matter and NOx content of the exhaust. The device comprises a number of longitudinal inlet channels and outlet channels, the inlet channels being plugged at the exit face, and the outlet channels being plugged at the entry face. The interiors of the inlet channels are coated with a particulate matter catalyst coating, and the interiors of the outlet channels are coated with a selective catalyst reduction catalyst coating.

Abstract: The present invention provides a system for controlling semiconductor packaging particulate contamination. According to the present invention, a semiconductor packaging component (102) is provided, having a first surface (104) along which a plurality of connection features (110, 112) are disposed or located, and an area (202) to which a semiconductor die is to be connected. One or more areas along the first surface are covered with an encapsulant (200) to isolate the area(s) from deleterious stresses and to impede the egress of any particulate matter therefrom.
