The EVSE comprises a coupler and an AFCI device including: a controller including a processor and a memory, circuitry and computer-readable firmware code stored in the memory which, when executed by the processor, causes the controller to: detect an arcing level of arcing between the coupler and a charge port of the EV or any other series or parallel arcing within the EVSE, compare the arcing level to a threshold level to determine a hazardous nature of arching, and analyze the arcing level to determine not only if it is currently hazardous but if it is likely to become hazardous in a near term and recommend repair or replacement of the coupler and the charge port before damage occurs.

Abstract: Systems and methods for detecting features in ultrasound images and delineating boundaries that representative of the detected features. A method can include determining a boundary of a feature in a displayed ultrasound image, determining a closed polygon that represents the feature based on the boundary, and determining information of the feature using the dimensions of the closed polygon. The ultrasound image and graphical representations of the feature (e.g., the boundary, the closed polygon) can be displayed in a user interface on a touch screen display. The method can include receiving user input indicative of a location of the feature, and adjusting the feature boundary and closed polygon based on user input. The method can also include determining an area and/or a perimeter of the feature based on the closed polygon.

Abstract: A trap has a housing including an entrance. Internally, the trap has a trigger structure including a trigger plate and a latch mechanism, coupled with the housing; and a pivoting structure pivotally coupled with the housing and adapted to releasably engage with the latch mechanism of the trigger structure. When the trap is triggered by a rodent, the pivoting structure disengages from the latch mechanism and the pivoting structure pivots towards a rear wall of the housing and the trigger plate, and the trigger plate pivots toward the pivoting structure, moving the rodent against towards the rear wall of the housing and trapping the rodent between the pivoting structure and the rear wall. Once the trap is triggered, the rodent is contained and in most cases, killed, within the trap.

Abstract: A nuclear fuel assembly is constructed with fuel assembly components that are wire wrapped and positioned in hexagonal rings within a fuel assembly duct. The fuel assembly components positioned in an outermost ring of the fuel assembly are wire wrapped with a pitch that is shorter than fuel assembly components positioned at an interior ring of the fuel assembly. The shorter pitch at the outer ring of the fuel assembly increases pressure drop of a coolant fluid at the edge and corner subchannels and thereby reduces the temperature gradient across the fuel assembly, which provides a higher output temperature of the nuclear reactor without substantially increasing peak temperature of the fuel cladding.

Abstract: A nuclear reactor is designed to allow efficient packing of components within the reactor vessel, such as by offsetting the core, and/or vertically stacking components. The in-vessel storage system can be separate from the support cylinder and these components can be fabricated and shipped separately and coupled together at the construction site. Furthermore, the in-vessel storage system can be located adjacent to the core rather than being located circumferentially around it, and may also be located beneath the heat exchanger to further improve packing of components within the vessel. Through these, and other changes, the delicate components can be manufactured in a manufacturing facility, assembled, and shipped by commercial transportation options without exceeding the shipping envelope.

Abstract: A nuclear reactor is constructed in sub-modules and super modules which are manufactured, packaged, and shipped to a construction site.

The modules are assembled on-site, and some of the modules remain within their respective shipping containers after assembly. One or more of the shipping containers may be used as concrete forms to support the pouring of concrete in between selected modules. The concrete may be used for structural support, shielding, or both.
