Systems and methods for context-aware vulnerability risk scores
Systems and methods are provided for vulnerability proofing the use of risk scores in the administration of hardware components of an IHS (Information Handling System). Proposed configurations for a first of the hardware components of the IHS are detected, where the proposed configurations are associated with a risk score. Catalogs specifying known vulnerabilities of hardware components are accessed and used to determine whether any of the proposed configurations of the first hardware component are identified as vulnerable in one or more of the catalogs. When a vulnerability for the proposed configuration is identified in the catalogs, the risk score of the configuration is increased based on the vulnerabilities identified in the plurality of catalogs. When the risk score is increased to an elevated level, the hardware component is disabled until the proposed configurations are changed to include no configurations with vulnerabilities identified in the catalogs. |

Updating one or more databases based on dataflow events
Database environments may choose to schedule complex analytics processing to be performed by specialized processing environments by caching source datasets or other data needed for the analytics and then outputting results back to customer datasets. It is complex to schedule user database operations, such as running dataflows, recipes, scripts, rules, or the like that may rely on output from the analytics, if the user database operations are on one schedule, while the analytics is on another schedule. User/source datasets may become out of sync and one or both environments may operate on stale data.

Layered apparatus and method
Aspects of the disclosure are directed to apparatuses and/or methods involving a wall patch. As may be implemented in accordance with one or more aspects characterized herein, a wall patch has a plurality of layers including a base layer having an upper surface and a lower surface, and stacked layers stacked over the upper surface of the base layer. Each stacked layer is stacked on one of the other layers and has an exposed lower surface region that extends laterally beyond the layer upon which it is stacked. Adhesive may operate to adhere the exposed lower surface regions and the lower surface of the base layer may be adhered to a wall surface. The stacked layers, base layer and adhesive to provide a gradient defined by the thicknesses of the layers and adhesive, and defined by the area of the exposed lower surface regions of the stacked layers. |

Tile niche holder tool, method, and system
A support tool for installing tiles onto a wall above a niche in the wall provides support for tiles being mounted above the niche. The tool includes a support plate configured to be secured to or braced against an upper surface of the niche. A tile support bar supporting lower edges of the tiles may be adjusted and held in a selected vertical position relative to the plate, so that lower edges of tiles may be placed in a desired vertical position relative to the upper surface of the niche. The tile support bar may be slidably supported on a support rod in a selected position by a nut threaded onto the support rod. The tool may be secured in position by screwing the support plate onto the upper surface of the niche, or by bracing the tool in place using a length-adjustable extender assembly. |

Systems and methods related to liquid drainage
Systems and methods for draining liquids include spaced support members and drainage ribs extending therebetween. Adjacent rows of drainage ribs may establish a general checkerboard pattern of ribs and interstitial spaces therebetween. Drainage ribs may have a differential height along their length, though may have substantially coplanar bottom surfaces. A first support member is provided with stress risers to enable enhanced bending capability to provide a customizable device width for mating with predetermined liquid conduit sizes, such as roofing gutters having upward-facing channel widths. |

Connector arrangement and a method for weather proofing a roof window arrangement
A connector arrangement for a flashing assembly for use in a roof window arrangement is disclosed. It comprises a base connector element, an elevation element and a top connector element. Both connector elements have a gutter in their exterior side, and the gutter is open at one end so that water can drain out of it. An attachment section on the interior side of the base connector element is configured for being attached to a bracket used for connecting a roof window to a load-bearing structure, and the elevation element supports the top connector element so that it is positioned above the base connector element. In the mounted state the second end of the top connector element is arranged above the gutter of the base connector element and their length directions extend substantially in parallel to each other. A method for weather proofing a roof window arrangement is also disclosed. |

Foldable truss structure, in particular for solar tracker
The invention concerns a truss structure including a plurality of longitudinal members extending parallel to one another in a main extension direction and crossmembers (9) distributed in the main extension direction to connect the longitudinal members mechanically two-by-two, forming a plurality of polygons (11) each contained in a plane perpendicular to the main extension direction.According to the invention, each crossmember (9) connecting two longitudinal members includes a first half-crossmember (9a) with a first end connected to one of the two longitudinal members so as to be able to pivot about a first axis (X1-X′1) and a second half-crossmember (9b) a first end of which is connected to the other of the two longitudinal members so as to be able to pivot about a second axis (X2-X′2). The two half-crossmembers are connected to one another by an articulation hinge (13) allowing relative rotation of the two half-crossmembers (9a, 9b) about a third axis (X3-X′3). The first, second and third axes are parallel to one another and orthogonal to the main extension direction, allowing the truss structure and each crossmember (9) to pass from a deployed position to a folded position in which the first and the second half-crossmembers (9a, 9b) of each crossmember (9) extend substantially parallel one alongside the other in said main extension direction. |
