  • Patent number: 11795646
    Abstract: A system for reducing contaminants in body of water is shown and described. The system has a first land mass located within a body of water. A sediment trap, located on the floor of the body of water, is configured to collect sediment. Enclosed within the first land mass is a tussock mass area, surrounding a central area, and configured for collecting sediment and building a second land mass. The central area of the system is configured for removing contaminants from sediment. Sediment is moved from the sediment trap to the central area by a first ingress conduit and a pumping system. Filtered water migrates from the central area to outside the first land mass via an egress conduit; contaminated sediment is sequestered in the central area enclosed by the tussock mass area.

  • Patent number: 11348608
    Abstract: A method of manufacturing a tri-stage assembly is described herein. The method includes attaching a first microactuator and a second microactuator to a trace gimbal to a flexure during a PZT on flexure process (POF). The first microactuator is located at a distal end of the flexure and the second microactuator located at a proximal end of the flexure. The method also includes welding the trace gimbal to a baseplate, and a load beam to secure the trace gimbal including the first microactuator and the second microactuator.

  • Patent number: 9719551
    Abstract: An injection-molded plastic roofing membrane plate includes a body and multiple cleats. The cleats extend from a bottom surface of the body. Each of the cleats has a rounded terminal end with a rounded terminal surface. The rounded terminal surfaces make surface-to-surface abutment with an underlying membrane in installation. The rounded terminal surfaces reduce wear on the underlying membrane that may otherwise occur.
