    摘要： Objects of the present invention are provide an evaluation method of ship propulsive performance in actual seas, an evaluation program of ship propulsive performance in actual seas and an evaluation system of ship propulsive performance in actual seas capable of precisely evaluating ship propulsive performance in actual seas on the same scale also before the ship sails for example. As solving means of the objects, a standard sailing model 2 of the ship in actual seas is set, a sailing condition of the ship and a ship condition of the ship are input to the standard sailing model 2, the standard sailing model 2 into which the sailing condition and the ship condition are input and the ship condition are applied to a previously verified calculating method 1 of ship performance in actual seas, and ship propulsive performance in actual seas is evaluated.

    摘要： A device for towing a watercraft is disclosed. The device comes in a box-like structure such as a lunch box, tackle-box or cooler. The device connects to the watercraft via a cable. The watercraft includes an inner tube, a stand-up paddle board, a kayak, etc. The device stores personal items and electronic components. The device includes a propulsion system for providing thrust force to propel the device in a given direction. The device tows the watercraft with or without a user on it in the given direction and speed defined by the user. The device includes a transceiver for receiving instructions wirelessly from an electronic device operated by the user. The device allows the user to stand or sit on the watercraft and perform a variety of activities such as photography, eating, communicating, etc. while being towed.

    摘要： Mosquitoes are vectors for many dangerous diseases such as Malaria, Dengue, Yellow Fever, West Nile, and those from Zika virus etc. Mosquito transmitted diseases occur mostly in tropical, developing countries and create public health crises due to lack of adequate resources and rapid transmission. Malaria took 429,000 lives in 2015 and the impending Zika crisis shows the need for effective mosquito control. Nearly half of the world's population is at risk of malaria. Current mosquito control efforts focus on reducing the population of mosquitoes. The many mosquito control strategies such as using tarps to suffocate larvae, insecticides, genetic engineering, biocontrol using fish etc. have substantial drawbacks. These methods are environmentally hazardous, expensive, inefficient, hard to maintain, bulky, or energy intensive. Mosquitoes breed in stagnant water. They cannot breed in agitated water or running water. Thus, this patent describes water agitators that are environmentally safe, efficient, and cost-effective. In this patent, three water agitators prototypes are presented. They are self-sustaining, lightweight, mobile, and have minimal potential for misuse. The agitators consume solar energy. They are self propelling and do not require maintenance, such as changing parts. They are designed to be inexpensive, reusable, and mass-producible. These agitators can cover a much larger area of water compared to their size. They target small to large water areas. Agitators are versatile and can be used in flower vases, open rain jars, tire tracks, mining pits, small ponds etc.

    摘要： A maneuverable platform capable of operating on both fluid bodies (e.g., lakes, rivers, oceans, etc. in either liquid or frozen form) and land is provided. The platform has an above water portion formed of one or more sections onto discrete sections of which are positioned a number of buoyant propulsion members configured to support the above water portion and engage a fluid body or the ground to collectively provide support, propulsion and steering for the platform. The buoyant propulsion members are configured such that they provide buoyancy to the platform when the platform is at rest and lift when the platform reaches a specified hydrodynamic speed such that the platform planes atop the fluid of the fluid body during operation. The maneuverable platform, including the above water portion and the buoyant propulsion members, may be modular such that the platform may be split into sections of predetermined configuration to operate independently.

    摘要： A power system is provided for a marine or petroleum drilling vessel. The power system may have a plurality of power sources, at least one power consumer, and an input device configured to generate a signal indicative of a desired output. The power system may also have a load manager associated with the at least one power consumer and configured to create a power demand for the plurality of power sources based on the signal and an actual output, and a controller. The controller may be configured to determine a plurality of performance goals for the plurality of power sources, determine a priority of the performance goals, retrieve from the plurality of power sources at least one performance map corresponding with each performance goal, and selectively apportion the power demand between of each of the plurality of power sources based on the at least one performance map and based on the determined priority.

    摘要： A jet propelled watercraft includes a vessel body, a jet propulsion mechanism, a bucket, and a controller. The jet propulsion mechanism is configured to propel the vessel body. The controller is configured and programmed to control a thrust of the jet propulsion mechanism to propel the vessel body. The bucket is configured to move to a retracted position spaced away from the jet of water ejected from the jet propulsion mechanism and a jet receiving position to receive the jet of water ejected from the jet propulsion mechanism. The controller is configured and programmed to change an increase rate of the thrust in accordance with a forward speed of the vessel body until the thrust is increased to a predetermined value after the bucket has been moved from the retracted position to the jet receiving position.
