Abstract: An electrical energy storage device (20) includes a substrate (22), an anode layer (30), a cathode layer (26), and a separator layer (28) between the anode layer and the cathode layer. The substrate has multiple sets of intersecting cavities (21) passing through the substrate in different directions. The anode layer, cathode layer, and separator layer are formed over a surface of the substrate within the cavities.

Abstract: Provided is a foldable curtain rod configured for mounting thereon a curtain. The rod includes at least two elongated rod segments consecutively articulated to one another via a coupling arrangement allowing pivotal displacement of one rod segment with respect to the other. Each of the rod segments is configured for supporting a respective portion of the curtain, extending along a hanging line. The curtain rod is configured for assuming at least a first, deployed position in which the rod segments are essentially axially aligned to provide the curtain rod with a maximal span thereof and a second, folded position in which the rod segments are substantially parallel to one another to provide the curtain rod with a minimal span thereof. In the second, folded position, the hanging lines of the respective rod segments are spaced from one another.
