Abstract: Systems, apparatuses, and methods for enhancing handling of a sample cylinder may include first, second, and third stations, each configured to receive a sample cylinder containing a material sample. The first station may include a first mounting fixture configured to be attached to the sample cylinder, a viewing glass to facilitate inspection of a portion of the material sample, and a first valve configured to remove a portion of the material sample from the sample cylinder. The second station may include a second mounting fixture and a second valve to provide fluid flow between a source of pressurized gas and the sample cylinder, thereby to pressurize the sample cylinder. The third station may include a third mounting fixture configured to be attached to the sample cylinder and a third valve to provide fluid flow between the sample cylinder and ventilation ductwork or a receptable.

Abstract: Methods, systems, and computer programs are presented for automatic evaluation of security incidents. One method includes receiving a resolution status, for a set of insights, indicating if each insight was a true or a false positive. A global training set, comprising the resolution status for the insights, is generated, and a local training set with a subset of the insights associated with a first user. A machine-learning (ML) program is trained, using the global training set, to obtain a global model, and using the local training set to obtain a local model for the first user. When a new insight for the first user is detected, a global score is obtained using the global model, and a local score is obtained using the local model. A confidence score, calculated based on the global and local scores, is presented as an indication of an estimated severity of the new insight.

Abstract: Technical solutions are described for diagnosing an input power supply providing power to a motor. A method includes: generating a sinusoidal stimulus signal; applying, using the input power supply, the sinusoidal stimulus signal to the motor; measuring a response to the sinusoidal stimulus signal; determining a degraded condition of the input power supply based on the response to the sinusoidal stimulus signal; and performing an action in response to determining the degraded condition of the input power supply.

Abstract: A method for diagnosing an input power supply providing power to a motor includes: applying, using the input power supply, a power stimulus to the motor; measuring a response to the power stimulus; calculating, based on the response to the power stimulus, a metric indicative of a status of the input power supply; determining a degraded condition of the input power supply based on the metric indicative of the status of the input power supply; and performing an action in response to determining a degraded condition of the input power supply. The action may include one or more of: limiting an output power supplied to the motor; generating a diagnostic trouble code; and/or notifying an operator of the degraded condition of the input power supply.

Abstract: A pump comprising a volute housing, a rotatable shaft, and an impeller. The volute housing comprises a volute cavity side wall, an upper cylindrical wall, and an upper wall. The upper cylindrical wall extends upwardly from an upper perimeter edge and includes an upper recessed notch formed therein. The upper wall extends radially inwardly from the upper cylindrical wall. The rotatable impeller is operatively coupled to the rotatable shaft and comprises a top cylindrical wall and a top flange. The top cylindrical wall extends upwardly from a top perimeter edge of the top flange and includes a top recessed notch formed therein. The top cylindrical wall is separated from the upper cylindrical wall of the volute housing by an upper annular gap. The top recessed notch of the rotatable impeller and the upper recessed notch of the volute housing may be slot-shaped or wedge-shaped.

Abstract: A system for delivery of a medical device includes a delivery member and a medical device, which is mounted to the delivery member and releasably retained in a delivery configuration for endoluminal delivery of the medical device toward a treatment site in a human vessel. The delivery member includes an elongated first portion configured to extend outside of the body from a first percutaneous access site and an elongated second portion configured to extend outside the body from a second percutaneous access site to allow positioning of the medical device at the treatment site by manipulation of the first portion and second portion from outside of the body.

Abstract: A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.

Abstract: A macerating apparatus for a toilet in which the problem of jamming the macerator at startup is solved by rapidly detecting the flushing of the toilet and accelerating the macerator before motion-jamming solid objects in the effluent from the toilet can reach the macerator. The macerating apparatus may be comprised of a macerating cutter operatively connected to a motor, and a sensor in communication with the motor. The sensor may detect the flow of effluent from the toilet toward the macerator, the flow of makeup water from the supply tank into the toilet, or the mechanical action of the mechanism used to flush the toilet. The apparatus may include an intake basket having an asymmetric inlet tube and containing the macerating cutter, wherein the asymmetry of the inlet tube provides additional operating clearance between a cutting blade of the macerating cutter and the intake basket.
