Abstract: An anti-proliferation technique is disclosed to reduce the likelihood of nuclear proliferation due to the use fissionable fuel salts. The technique includes doping the fuel salt with one or more elements (referred to herein as activation dopants) that, upon exposure to neutrons such as would occur in the fuel salt when a reactor is in operation, undergo a nuclear reaction to, directly or indirectly, form highly active “protecting isotopes” (of the same element as the activation dopant or a different element). A sufficient mass of activation dopants is used so that the Figure of Merit (FOM) of the fuel salt is decreased to below 1.0 within some target number of days of fission. This allows the FOM of the fuel salt to be controlled so that the fuel becomes too dangerous to handle before to the creation of a significant amount of weaponizable isotopes.

Abstract: Methods and apparatuses related to federated search of multiple sources with conflict resolution are disclosed. A method may comprise obtaining a set of data ontologies (e.g., types, properties, and links) associated with a plurality of heterogeneous data sources; receiving a selection of a graph comprising a plurality of graph nodes connected by one or more graph edges; and transforming the graph into one or more search queries across the plurality of heterogeneous data sources. A method may comprise obtaining a first data object as a result of executing a first search query across a plurality of heterogeneous data sources; resolving, based on one or more resolution rules, at least the first data object with a repository data object; deduplicating data associated with at least the first data object and the repository data object prior to storing the deduplicated data in a repository that has a particular data model.

Abstract: A cross reality system that provides an immersive user experience by storing persistent spatial information about the physical world that one or multiple user devices can access to determine position within the physical world and that applications can access to specify the position of virtual objects within the physical world. Persistent spatial information enables users to have a shared virtual, as well as physical, experience when interacting with the cross reality system. Further, persistent spatial information may be used in maps of the physical world, enabling one or multiple devices to access and localize into previously stored maps, reducing the need to map a physical space before using the cross reality system in it. Persistent spatial information may be stored as persistent coordinate frames, which may include a transformation relative to a reference orientation and information derived from images in a location corresponding to the persistent coordinate frame.

Abstract: The present disclosure provides systems and techniques for determining a grip layout for a gun. The techniques include obtaining an image depicting a hand, obtaining calibration data associated with the image, calculating a real distance between a first landmark of the hand and a second landmark of the hand, and determining a grip layout for the gun based on the real distance between the first landmark and the second landmark. Calibration data may include a scale for the image or data that may be used to derive the scale, such as an object of known dimensions, an angular field of view, or a distance between the device used to capture the image and the hand. The grip layout may include a backstrap size, a sensor size, a sensor location on the gun, or any combination thereof.

Abstract: A toilet shield comprises a tube, a first arm, a second arm, and a raised collar. The first arm is coupled to a first side edge of a lumen of the tube. The second arm is coupled to a second side edge of the lumen of the tube. The tube is configured such that the lumen of the tube opens in response to the first arm and the second arm being extended in generally opposite directions. The raised collar is disposed between and rises above the first arm and the second arm and is configured to deflect liquid feces expelled from a defecating human toward a rear portion of a toilet. An expandable pleat is disposed on each side of the raised collar.

Abstract: A vegetable slicing shield includes a root, a u-shaped handle, and a plurality of tines. The root is medially disposed between the u-shaped handle and the tines. The u-shaped handle is coupled with the root at opposing lateral regions of a first side of the root. The plurality of tines have first ends coupled with a second side of the root and extending outward from the root to second ends which form a row spaced apart points. Open slots are defined between adjacent tines of the plurality of tines. A subset of the tines are shaped between their first ends and their second ends to form slices of a containment basket which is curved in three-dimensions.

Abstract: In a finishing apparatus, such as would be used with a copier or high-speed printer, an applicator places stickers on a folded sheet or booklet, to prevent the sheet or booklet from unfolding or opening. At one point in the operation, the folded sheet or booklet is “backed up” in its basic process direction to receive a sticker on its trailing edge, and backed up further so that the sticker is folded over the trailing edge by a pair of crease rolls.

Abstract: A refrigerant flow-control device is automatically operable between a normal or low-flow condition and a pressure relief or high-flow condition in response to pressure drop across the flow-control device, in one embodiment the flow-control device includes a tubular-shaped body having an inlet, an outlet, and a refrigerant passageway extending from the inlet to the outlet, a cylindrically-shaped restrictor secured within the tube and forming a second restriction, and a cylindrically-shaped collar secured within the tube and forming a poppet-valve flow passage. The collar is spaced-apart from the restrictor within the tube. A poppet is located within the tube partially between the restrictor and the collar and carries a valve element. The poppet is movable between a first position closing the poppet-valve flow passage to generally prevent refrigerant flow therethrough and a second position opening the poppet-valve flow passage to permit refrigerant flow therethrough. The poppet forms a first restriction.
