摘要： The present invention relates to a water flow measuring drifting buoy capable of preventing stranding and resisting impact, which includes: a ball-game table-shaped inflation body with a counterweight capable of drifting autonomously in a direction of a main stream of a water flow, wherein the inflation body is provided with at least two inflation connectors, and the inflation connectors are of a cross-shaped structure formed by connecting in a conical distribution with 4 inflation-stabilizing rods uniformly distributed along a circumferential radiation; the counterweight is 4-10 fan-shaped steel plates arranged annularly in the center of the bottom of the inflation body, and the fan-shaped steel plates are flexibly connected to each other to be able to shake. The ball-game table structure used in the present invention is selected by comparing various shapes to push a buoy to the middle of a river where the water flow is turbulent by using the difference in a water flow speed to prevent the water flow from being stranded where the water flow is slow or being blocked by a rock at a river bank so as not to continue the drift. The steel plate of the cross-shaped structure in the fan-shaped distribution is used, so that the buoy can be turned up and continue to drift once it has fallen to the ground, greatly improving the efficiency of drift.

摘要： The present disclosure relates to methods, apparatuses, and systems for a compact, low-cost drift buoy for use in a variety of applications. An example includes a drift buoy including a body defining a payload cavity; a float; and a controller, where the controller is configured to cause the drift buoy to release a payload when one or more predetermined conditions are satisfied. According to some embodiments, the controller is configured to establish a location of the drift buoy. According to certain embodiments, the one or more predetermined conditions include a location condition, where in response to the location of the drift buoy being within a target location, the controller causes the drift buoy to release the payload from the payload cavity.

摘要： An air deployable buoyant device for transmitting data on its location and the conditions in the air as it descends to the surface of a body of water, and on conditions on a body of water on a real-time basis is disclosed. The device includes a buoy and a plurality of sensors and a transmitter associated with the buoy. The transmitter transmits data on the location of the device and the conditions in the air and on a body of water on a real-time basis to at least one receiver. The receiver may be located over the horizon or in line of sight with the device. The sensors are in communication with the transmitter, and each sensor measures at least one condition in the air and/or on a body of water to assist in locating a person in the water and provide information on the water conditions to a rescue team. Methods of deploying and using the buoyant device are also disclosed herein.

摘要： An underwater positioning system comprises a plurality of underwater beacons. A beacon, in response to a signal sent by an underwater vehicle, responds with a signal comprising one or more characteristics to identify the beacon. Components of an access algorithm are provided to the underwater vehicle. The access algorithm determines a location of the beacon based on the beacon's identity. A position of the vehicle is determined based at least in part on the location of the beacon.

摘要： Disclosed is a novel type of computing apparatus which is integrated within a buoy that obtains the energy required to power its computing operations from waves that travel across the surface of the body of water on which the buoy floats. Additionally, these self-powered computing buoys utilize their close proximity to a body of water in order to significantly lower the cost and complexity of cooling their computing circuits. Computing tasks of an arbitrary nature are supported, as is the incorporation and/or utilization of computing circuits specialized for the execution of specific types of computing tasks. And, each buoy’s receipt of a computational task, and its return of a computational result, may be accomplished through the transmission of data across satellite links, fiber optic cables, LAN cables, radio, modulated light, microwaves, and/or any other channel, link, connection, and/or network.

摘要： The present invention provides an eco-friendly underwater buoy and a manufacturing method therefor, the underwater buoy comprising: a liner main body of which the inside is hollow; a winding member which is melt welded on the outer surface of the liner main body by winding, and which absorbs external shock; and buoy couplers embedded in both ends of the liner main body so as to couple adjacent underwater buoys to each other. The present invention winds, through filament winding, a wire, in which a glass fiber, a resin and the like are mixed, around the outside of a liner structure so as to manufacture an underwater buoy, and thus, since the underwater buoy is made of a composite material, the appearance of the buoy structure can be stably maintained for a long time without damage caused by various underwater shocks, so that underwater environmental pollution caused by buoy structure damage can be minimized, thereby maximizing the eco-friendliness of the underwater buoy.
