Abstract: We describe various methods for making preprogrammed logic systems using knotted yarns. We show that the topology of the knots controls the mixing ratio of the reagents coming into the knots, and thus the ratio can be adjusted by choosing a specific knot. A serial dilutor is built by knotting multiple yarns into a web of well defined dimension. In addition stretchable yarn can be used to control the capillary pressure and hence the flow rate of the liquid, by pulling the yarn. Furthermore, we demonstrate the possibility of patterning impermeable/hydrophobic regions in to the yarn. Finally, we propose that biodegradable yarns can be used into these platforms to build various multi/single cellular scaffolds.

Abstract: A multipurpose cinch cleat and method of securing a line thereto with maximum simplicity, to prevent longitudinal movement of the line relative to the cleat in one direction, or if desired, in both directions. The cleat includes an elongated support having a cantilevered post with a free end extending outwardly therefrom, the support having opposite end portions which are fixedly mounted upon a supporting surface with the support being spaced from therefrom.

Abstract: A method permits a knot to be tied in a rope that is being held with one hand. The rope includes a first end and a weighted second end, and has a length extending therebetween that permits a user implementing the method to tie a knot therein. Initially the rope is held in one hand such that the weighted second end of the rope is suspended and the rope is taut between the hand and the second end. Moving the hand holding the rope in a first direction and in a second direction causes a loop to form between the hand and the rope second end. As the rope is moved in the opposite direction, momentum permits the rope weighted end to pass through the rope loop to form a knot.
