Abstract: An electronic assembly may include a component comprising conductive studs disposed over an active layer of the component. A first encapsulant layer may be disposed around four side surfaces of the component, over the active layer of the component, and contacting at least a portion of the sides of the conductive studs. A substantially planar surface may be disposed over the active layer of the component, wherein the substantially planar surface comprises ends of the conductive studs and the first encapsulant layer. The first encapsulant layer comprises a roughness less than 500 nanometers. First conductive elements may be disposed over the encapsulant and coupled with the conductive studs. A second layer of encapsulant may be disposed over the first conductive elements.

Abstract: A muzzle loading firearm, such as a rifle, having a firing nipple which communicates with the rear of the barrel bore and mounts thereon a firing cap. The nipple is positioned within a chamber formed in the interior of the stock directly adjacent the rear end of the barrel. The chamber opens outwardly through one side surface of the stock. An openable and closable cover is mounted on the stock adjacent the side surface thereof for permitting closing of the chamber. The trigger mechanism is mounted on the stock substantially forwardly from the firing nipple. An elongated firing rod is slidably mounted internally of the stock and projects forwardly from the chamber to the trigger mechanism. A latching structure coacts between the trigger member and the firing rod to hold same in a forward position such that, when the trigger is activated, the firing rod is released and spring urged rearwardly to impact against and detonate the firing cap.

Abstract: A separable fastener including a stud component and a latching sleeve component, the stud component being arranged for installation, in a sheet member having a rectangular opening, by limited insertion and rotation; the latching sleeve member being installed in a second sheet member, having a rectangular opening, by axial movement.
