Abstract: In a described example, an apparatus includes: a package substrate for mounting a semiconductor die to a die side surface, the package substrate including leads spaced from one another; and cavities extending into the leads from the die side surface, the cavities having sides and a bottom surface of the lead material, the cavities at locations corresponding to post connect locations on the semiconductor die.

Abstract: Embodiments of the invention relate to a child sleeping system comprising a blanket, a pillow, pillow band and a carrying pouch. The blanket has a generally rectangular configuration and a length and a width. The pillow has a generally rectangular configuration filled with a non-allergenic material, and has a length and width, at least one of the pillow length and width in a predetermined dimensional relationship with at least one of the blanket length and width. The carrying pouch has a generally rectangular configuration, defines an opening at the first edge and communicates with the blanket second edge; the carrying pouch has a length and width in a predetermined dimensional relationship with at least one of the pillow length and width. The carrying pouch is adapted to receive the blanket and pillow when the pillow is folded over and the blanket side edges are folded over the pillow.

Abstract: The invention provides gene transfer compositions using as the gene carrier a biodegradable polymer that contains one or more cationic alpha amino acids, such as arginine or agmatine. The compositions form a tight soluble complex with a poly nucleic acid suitable for transfecting target cells to effect translation of the cargo poly nucleic acid by the target cell. Thus, such compounds are useful both in vitro and in vivo.
