Abstract: Described a computer-implemented method for the automated design of a mechanical actuator by using metamaterials. The method comprises: defining an initial lattice model of the metamaterial, constituted by the repetition of basic geometric elements formed by a plurality of nodes connected by a plurality of beams; defining several groups of nodes; and iterating a series of steps, including: modifying a current test lattice, on the basis of a pseudo-random decision determined by means of a computational algorithm; simulating, by means of computational simulation, the mechanical response of the modified test lattice; calculating a figure of merit of the modified test lattice on the basis of positions of input and output nodes in presence of an input mechanical stimulus; either accepting or rejecting the modified test lattice; and finally defining the current test lattice for the subsequent iteration is as the initial lattice at the first iteration.

Abstract: The disclosure is directed to a circuit that may detect a single short in a chain of loads, such as light emitting diodes (LEDs). The circuit may drive either multiple LED chains or a single LED chain to determine whether one, or more, of the LEDs in the LED chain is no longer working because of a short. The circuit determines whether the LED chain voltage satisfies a threshold based on a single LED voltage drop. Therefore, the same circuit may be used for applications regardless of the number of LEDs in an LED chain. Additionally, the circuit, according to the techniques of this disclosure may use may use no output pins, other than those used to deliver current to LED chains, regardless of the number of LED chains that the circuit drives.

Abstract: A method for manufacturing insulated structural panels for walls, roofs, ceilings, and floors with fixed structural members inserted in to machined cavities that allows for seamless joining of adjacent panels, all stud distances are at industry standard, for sheet hanging simultaneously with truss support without needing top plates for load distribution. The panels yield extreme insulation, sound attenuation, and structural values, while remaining light weight and economical. The composites are non out gassing and zero flame spread, also free from deterioration, and are air, vapor and moisture impermeable. Additional stiffener web is inserted at every four feet of height for higher shear, wind, snow, live and dead loads, and attached to the foundation with a “U” shaped steel channel or track secured with screws to the bottom and top of the panel. Track is also attached at doors and windows openings. All finishes, can be attached to the panels.

Abstract: A new and distinct variety of Zoysia japonica turfgrass, called `SS-500`, is characterized by its color, long and wide leaf blades, large stolons, an open growth habit, and rapid establishment rate.

Abstract: A new and distinct variety of Zoysia japonica turfgrass, called `SS-300`, is characterized by a short, narrow leaf blade, compared to other varieties of Zoysia japonica. The growth habit is low and compact. `SS-300` has a rapid establishmentrate.
