  • Patent number: 11327201
    Abstract: Systems and methods relate to generating a self-consistent sediment model. Initially, void ratio extrema are determined for each sediment layer in a sediment column based on historical data or a direct measurement of the sediment column. Initial stress is determined for each sediment layer based on the void ratio extrema. A porosity model is generated for each sediment layer based on the void ratio extrema and the initial stress. At this stage, measured data is obtained for each sediment layer from a data collection device positioned at or near a geographic location of the sediment column. The porosity model of each of the sediment layer is combined with the measured data of the sediment layer to generate the self-consistent sediment model for each sediment layer. The porosity model and the self-consistent sediment model of each sediment layer is updated based on updated measured data obtained from the data collection device.

  • Publication number: 20220126961
    Abstract: Provided is a radar and communications enhanced sail for a sailboat, sail ship, or sail drone. The sail includes a first sail section comprising an active communication system, a second sail section comprising a passive communication system, or a combination thereof. The active communication system includes an antenna array (transceiver) and a software-defined radio (SDR), while the passive communication system comprises a reflective panel or sections and/or array of reflector panels or sections. The active system utilizes its SDR and transceiver to communicate back and forth with an onshore SDR and transceiver to provide information as necessary. The passive system receives a radar signal via the reflective material on the sail and reflects the signal back at the radar, which produces a radar cross section indicating that there is an object (in this case the sailboat) in the ocean.

  • Patent number: 11313846
    Abstract: Exemplary inventive practice replicatively tests the effects of cleaning processes applied to marine hulls coated with biofouling-control substances. A sample (e.g., antifouling-coated panel) is coupled with a trolley that is linearly moveable via trolley wheels upon two parallel tracks provided along the length of an open rectangular box-shaped tank, partially filled with natural or artificial seawater. The cleaning element (e.g., brush bristles) points vertically upward in a stationary position atop a motorized cleaning unit installed proximate the bottom of the tank. In accordance with the trolley's horizontal movement, and while the sample and cleaning element are immersed in seawater, the sample traverses the cleaning element in a contactual manner that mimics underwater cleaning dynamics for a hull surface.

  • Patent number: 11307105
    Abstract: A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.
