Patent number: 8449220Abstract: A tidal barrier is provided that may be selectively deployed in response to tidal changes. The tidal barrier includes a net having a tensile, membrane with an upper edge and a lower edge. The lower edge has a plurality of anchor points for affixing the lower edge to a seabed below a body of water. The tidal barrier further includes a bladder affixed to the upper edge and having a valve for selectively inflating and deflating the bladder. The bladder has a sufficient volume to cause the upper edge of the membrane to rise to a surface of the body of water when the volume is inflated with a gas. A pump is disposed in proximity to the tensile membrane and is in fluid communication with the valve of the bladder. The pump has a controller for selectively prompting the pump to inflate and deflate the bladder with the gas.Type: GrantFiled: August 9, 2012Date of Patent: May 28, 2013Assignee: Skidmore, Owings & Merrill LLPInventors: Craig W. Hartman, Mark P. Sarkisian

Patent number: 8256173Abstract: An environmentally sustainable form-inclusion system that can be utilized in reinforced concrete structures. A goal of this invention is to provide structural systems that achieve the highest level of environmental sustainability by minimizing the structure's carbon footprint and embodied energy. This engineered form-inclusion system uses materials that might otherwise become waste in landfills. The system is designed to significantly reduce raw materials, labor for placement, and transportation of material for building construction. Materials used in this engineered system, that might otherwise be placed in landfills, include but are not limited to plastic bottles, bags, waste Styrofoam, packing materials, rubber tires, and other similar waste materials, preferably compressed or assembled into controlled shapes. The shapes of these forms can be spherical, square, rectangular, cylindrical, or any other, and are specifically engineered to provide form inclusions to significantly reduce the material (e.g.Type: GrantFiled: November 17, 2008Date of Patent: September 4, 2012Assignee: Skidmore, Owings & Merrill LLPInventors: Mark P.
