Abstract: A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.

Abstract: A method of rehabbing reinforced concrete pilings while in service and without the requirement to demo or otherwise gain access over the ends of an existing column. Design adopts modern environmentally responsible fiber reinforced polymer rebar and other FRP stirrups uniquely shaped into spiral sections requiring only side access for placement, designed to permanently encase the piling with a totally non-rusting non-metal reinforcement lateral containment cage featuring preformed circumference stirrups that mechanically interlock vertically and lateral adjustability to control density. The spiral stirrups extending fully 360-degrees around an existing piling with an additional overlap of at least 45 degrees.

Abstract: Embodiments of the disclosed technology use an indexed value blending approach to compute blended values between two fixed values from a palette of base values. In one example, the disclosed technology uses a parameterized array that defines the available colors of a color palette and also orders those values so that any two values that are to be blended are located adjacent to (consecutively with) one another within the array. The array can be efficiently used to compute the necessary input values for a linear interpolation that then computes the desired blended value. For instance, the array can be used to identify a first color value and a second color value to be blended in an interpolation process as well as the degree of blending between the two (e.g., a blending control value (or alpha value)).

Abstract: Matrix basalt reinforcing members for concrete. The basalt members are specifically formed to provide tension support having a beneficial use with pervious concrete used in large areas such as sidewalk and parking lot. The basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable of supporting heavy loads such as trucks without cracking while allowing water to pass through the concrete. The basalt reinforcing members are formed from roving crosses and interlaces in between each side of the figure 8 shape to mitigate potential for sheer at crossovers.

Abstract: Matrix basalt reinforcing member constructed and arrange to provide lateral support for the longitudinal bar steel or FRP tendons that provide tensile strength to cementitious material or plastics to reduce bending moment by reducing the onset of shear. The reinforcement members are formed from continuous glass fibers treated with a thermoplastic thermoset polymer and formed into structures to provide structural resistance to bending-moment forces, compression forces, and torsional forces acting on the structure.

Abstract: A settling tank apparatus for removing solids from a solids-containing fluid, having a vertical cylindrical portion and a bottom portion having a downwardly-extending substantially torispherical, ellipsoidal, hemispherical or frusto-conical shaped curved interior surface. A jetting fluid source is provided in a lower region of the tank, preferably in the bottom of the tank, which directs a jetting fluid in a tangential direction in a plane substantially perpendicular to said longitudinal axis of the tank, to enhance rotational swirling of a created vortex in the bottom of tank when solids are drained therefrom, to thereby reduce deposition and build up of settled solids on the curved interior of the bottom of the tank. A system incorporating a plurality of tanks of such design and a method for removing solids from a solids-containing fluid using a tank of such design, is further disclosed.

Abstract: Basalt basket and dowel system to provide load transfer between adjoining slabs. The basket is designed as a placement jig to properly position dowels during the concrete placement phase of construction. Additionally to provide inherently tinsel and shear reinforcement to the edge of the concrete before during and after the contraction stress of curing concrete is relieved by scoring and to do so without the risk of rust spalling. The baskets and dowels are constructed from continuous basalt fibers admixed with an appropriate adhesive to produce the required strength and provide load predictions in a similar manner to steel calculations. The basalt basket is light weight and the configuration of its tendons interlaces provides sufficient space to allow concrete flow during placement and too prevent tinsel slippage within the cured concrete.

Abstract: A recirculation bin, a drill tailings handling apparatus, and a method of handling drill tailings is disclosed. The recirculation bin has a moveable plate member, which advantageously may be positioned, when excess tailings are being delivered to the recirculation bin, to deflect such excess tailings into a second containment bin, for subsequent re-delivery to the recirculation bin when capacity to process such drill tailings is then available. The handling apparatus contemplates a second container, which is disposed immediately adjacent the recirculation bin, to receive deflected tailings, and is open at one end thereof to permit entry of a front-end loader therein, and thereby permit excess tailings deflected into the second container to be scooped up and delivered to the recirculation bin, when the moveable plate member is positioned to then allow the recirculation bin to accept such delivery, at a time when processing capability for such drill tailings is available.
