Abstract: An electrical device includes a substrate, an insulating layer supported by the substrate, and an electrically conductive vertical interconnect disposed in a via hole of the insulating layer. The insulating layer may be configured to provide a coefficient of thermal expansion (CTE) that is equal to or greater than a CTE of the vertical interconnect to thereby impart axial compressive forces at opposite ends of the interconnect. The vertical interconnect may be a hybrid interconnect structure including a low CTE conductor post having a pocket that contains a high CTE conductor contact. At low operating temperatures, the high CTE conductor contact is under tension due to the higher CTE, and thus the high CTE conductor contact relieves strain in the device by void expansion and elongation.

Abstract: A paint roller assembly, comprising a frame assembly including a handle and a frame, where one end of the frame is attached to the handle and the other end includes a cross-member structure attached to the frame opposite and orthogonal to the handle end, a first paint roller cage rotatably mounted on a first branch of the cross-member section, and a second paint roller cage rotatably mounted on a second branch of the cross-member structure. Optionally, a first paint roller cover can be placed over the first paint roller cage, and a second paint roller cover can be placed over the second paint roller cage, wherein at least one of the first paint roller cage and second paint roller cage has an end covered in paint-absorbing material for applying paint into a corner between adjacent surfaces.

Abstract: Embodiments of the invention relate to polycrystalline diamond compacts including a substrate having a convexly-curved interfacial surface bonded to a polycrystalline diamond table. In an embodiment, a polycrystalline diamond compact includes a substrate including at least one side surface and a convexly-curved interfacial surface that may, in some embodiments, extend inwardly directly from the at least one side surface to form at least one peripheral edge therebetween. The polycrystalline diamond compact further includes a polycrystalline diamond table bonded to the convexly-curved interfacial surface of the substrate.
