A fastener (114) can be used to attach a trim component (112) to a vehicle body (110). The fastener can include a base (212) with a track (222) for receiving the vehicle body and allowing translation along a first directional axis (402). A retention snap (218) can extend from the base. The retention snap can be engageable with the vehicle body to removably couple the base to the vehicle body. A slot (216) can extend through the base. The slot can be configured to receive a clip (206) and permit translation along a second directional axis (408). The fastener can also include a window (226) formed in the base. The window can be configured to receive the clip when the clip is inserted into the slot, coupling the trim component to the vehicle body.

Generally described, one or more aspects of the present disclosure relate to threadless fastening systems, and components thereof, the threadless fastening system including a fastening washer including a conical spring, a retaining cup comprising one or more washer centering ribs, and an attachment pin, wherein the fastening washer is configured to press fit onto an interface surface of the attachment pin, and wherein the conical spring is configured to generate a joint preload between the fastening washer and attachment pin clamp surface.

A porous current collector assembly including a porous electrically insulating substrate and porous foil layers is described. The porous current collector assembly may enable simultaneous ion and electron conduction while maintaining selective electrical isolation of electrodes. Configurations and methods thereof, of porous current collector assemblies within electrodes, electrode assemblies, and electrode assembly stacks, and energy storage devices are also described.

Generally described, one or more aspects of the present disclosure relate to a solar panel mount (100) for a tile roof. The mount (100) includes a flashing (110) sized to replace one tile of the tile roof, a plurality of fasteners, a rail mount (120) including a plurality of fastener flanges (128) arranged in a mounting pattern, a plurality of fastener retainment inserts (160), a spacer (130), and a gasket (150). The spacer (130) is configured to be positioned on an opposite side of the flashing (110) from the rail mount (120), and the plurality of fasteners (140) are configured to secure the rail mount (120), the flashing (110), and the spacer (130) to a roof decking of the roof.

The present disclosure is directed to a semiconductor package. The semiconductor package includes a semiconductor die comprising a transistor, a lead frame having a surface on which the semiconductor die is at least partly stacked, and a molding material over the lead frame and encapsulating the semiconductor die. The surface includes a textured pattern at an interface with the molding material, and the textured pattern includes an array of features having less than 1000 micrometers between two adjacent features of the array of features.

Systems and methods are described for a system with circuit fault protection comprising a battery (106), an interrupting contactor (202A, 202B) electrically connected with the battery (106), and a controller (206). The interrupting contactor (202A, 202B) may be configured to electrically connect the battery (106) to an end of a load (102) in a closed state and to electrically isolate the battery (106) from the end of a load (102) in an open state. The controller (206) may, while the interrupting contactor (202A, 202B) is in a closed state, detect a fault in a circuit that includes the battery (106) and the interrupting contactor (202A, 202B). The controller (206) may further toggle the interrupting contactor (202A, 202B) to open in response to detecting the fault.

A system for pre-stretching film includes a starting cylindrical roll (202) of film, an intermediate roller (204) to receive film (208) from the starting cylindrical roll (202) of film and stretch the film (208) as it passes over the intermediate roller (204), and provide the film to a final non-cylindrical roll (206) that stores the film in a pre-stretched condition. The first intermediate roller (204) has a greater radius of curvature (i.e. less curvature) compared to the final non-cylindrical roll (206). Preferably, the starting cylindrical roll (202) and the final non-cylindrical roll (206) are detachable from the system.Preferably, the pre-stretched film (208) is pre-stretched to fit on a curved surface, such as a vehicle window where it may serve to provide window tinting to block ultraviolet rays.

Devices, systems and methods used to accurately and/or precisely calender materials and films (e.g., dry electrode materials and/or dry electrode films), and systems thereof, are described. These devices, systems and methods measure thicknesses of films on the calender rollers and/or adjust bulging of calender rollers. Such disclosures may enable active control and/or adjustment of the calendering system in order to more accurately and/or precisely control and/or adjust the thicknesses, densities and/or loadings of films.

An electrode for use in energy storage devices including an electrode film formed from an electrode film mixture including water and a solvent additive, and methods thereof, are disclosed. The electrode utilizing water and a solvent additive may aid in reducing compressive stress, creases and/or curvature during formation, thereby achieving improved electrode shape and/or strength.
