A system with a device including a hardware processor is configured to perform operations: receiving, by the device, a message over a wired medium, wherein the message has a frame including (a) a MAC address as a source MAC address for the frame and (b) a second MAC address as a destination MAC address for the frame, extracting, by the device, the frame from the message received over the wired medium, and wirelessly transmitting, by the device, the frame without modifying the source MAC address and without modifying the destination MAC address.

A reinforced geocell is made of flexible polymeric strips arranged in rows and interconnected in a staggered order lengthwise to form a three-dimensional cell structure when stretched in the direction normal to surfaces of the strips. The strips are provided with drainage apertures and are reinforced in a longitudinal direction with reinforcing threads having at least two fibrous elements twisted along full lengths thereof. A method for producing a geocell includes extruding a polymeric material for producing a sheet material, laying out twisted reinforcing threads onto the sheet material, calendaring the sheet material when heated to 120 to 200 C. to press reinforcing threads into the sheet material, cutting a reinforced sheet material into sheets, perforating the sheets for producing drainage apertures, cutting the sheets into strips, and interconnecting the strips in a staggered order to form a three-dimensional cell structure.

A tire assembly for use in reclaiming land from a marine environment. An anchor having at least one cable connected thereto acts as a base to which tires are connected by threading them down the cable to form a cylindrical tower of tires which can be filled with concrete or filler if desired. A plurality of the tire assemblies can be positioned adjacent to one another and further interconnected for stability purposes and can form the basis for further structural elements.

A system includes a geotextile material disposed over a layer of soil, a layer of aggregate disposed over the geotextile material, and a binder applied onto or over the layer of aggregate. At least some of the aggregate material is mixed with or bound together with the binder, in a top portion of the aggregate layer extending to a selected depth. The bound aggregate and binder can be substantially permeable to water flow, and configured to reduce erosion, migration or movement of the aggregate material and soil. A layer of revetment blocks can be installed over the aggregate, in order to direct water flow.

A swimming pool assembly, including a pool body defining a top edge and an bottom connected by a wall, an access port positioned through the bottom, a first conduit connected to the access port and extending away from the body, a valve connected with the first conduit, a second conduit connected with the first conduit and extending toward the top edge, wherein the second conduit is water permeable. An actuator is positioned in the second conduit and connected to the valve. First and second water level sensors are positioned to measure ground water level and pool water level. A microprocessor is operationally connected to the water level sensors and to the actuator, wherein when the ground water level exceeds the pool water level by a predetermined amount, the microprocessor sends a signal to the actuator to open the valve.

A kit for modifying a preformed swimming pool, including a fluidic access port for positioning through a preformed swimming pool body, a first conduit for fluidically connecting to the fluidic access port and extending away from the preformed swimming pool body, a first hydrostatic valve defining a hydrostatic fluid inlet and a hydrostatic fluid outlet and connectable in fluidic communication with the first conduit for passing water from the hydrostatic fluid outlet into the first conduit and through the fluidic access port, a second conduit connectable in fluidic communication with the first conduit and with the hydrostatic valve outlet, and a third conduit connectable in fluidic communication with the hydrostatic fluid inlet, wherein the third conduit is water permeable.

A system and method to create or elevate a berm of a liquid retention facility by placement of lightweight liquid impervious. The system and method can also be used to elevate the liquid retention height of the berm in combination with impervious liner retention material. By constructing the berm system on an existing levee, the effective height of the levee can be increased. The lightweight fill material provides the shape of the berm or levee extension. The liquid impervious liner material provides a watertight surface, the media for joining of the lightweight fill material, and the anchoring of the lightweight fill material to the existing berm or levee structure. The system may use solid wall hollow body structures to elevate the berm. The system may also use lightweight frames to support the vertical elevation of a liner above the berm.

A ground anchor system configured for introducing into a borehole, and comprising a plurality of straps each having a length dimension extending along a central longitudinal axis of the ground anchor system. Each of said straps has a width dimension taken along a major axis and a thickness dimension taken along a minor axis. The major axis and the minor axis are disposed at a transverse plane of the ground anchor system and intersect at a middle point. The middle point of each of said straps is intersected by an imaginary line extending through the longitudinal axis at the transverse plane. The imaginary line forms an angle smaller than 90 with the major axis of the respective strap.

This invention is directed to corrugated retention and filtration systems which are designed and installed to control sediment runoff. The corrugated systems creates a multiple of adjacent retention and filtration wedges with acute angles at their downstream vertexes for increased surface area and an increased number of structural support elements throughout the system. The corrugated retention and filtration system provides structural, hydrodynamic, and filtration features not available from a conventional linear systems used for sedimentation control applications.

A method and apparatus for creating moderately quiescent water in which salt marsh wetland grasses can endure and eventually establish without the need for the total elimination of the energy of occurring waves or the restriction of sediment passage
