摘要： When on-water control means 20 having moving means and capable of moving near a water surface controls a multiple underwater vehicles 30 which cruise in water, the moving means 23 controls movement of the on-water control means 20 such that the multiple underwater vehicles 30 are located in a control region X where the on-water control means 20 can position the multiple underwater vehicles 30 utilizing acoustic positioning means 24 provided in the on-water control means 20. According to this, it is possible to deploy and operate the multiple underwater vehicles in water and safely and efficiently carry out survey operation and the like such as water bottom exploration.

摘要： A dive mask provides underwater images and includes: a transparent lens; a frame; a strap arrangement; a water-proof housing; a camera; and batteries. A first portion of the frame receives the transparent lens, and a second portion mounts to a wearer's face. The strap arrangement secures the frame to the wearer's head. The water-proof housing is secured within the frame, with a least a portion thereof being sealed against a portion of the transparent lens. The camera is positioned within the water proof enclosure, and include a shutter button that may be depressed to capture still images or video recordings. The batteries are positioned in the water-proof housing and power the camera. A water proof port permits recharging of the batteries. A waterproof pouch with a re-sealable waterproof closure is releasably secured to one strap using a lanyard, and stores the user's personal belongings while diving.

摘要： Disclosed are a flexibly-driven small underwater robot and a driving method thereof. The underwater robot provided by the invention comprises a driving module and a propelling module. Two propelling modules are designed at head and tail portions, and the driving module is arranged between the two propelling modules. A rib plate in the driving module comprises a carbon fiber plate matrix and a piezoelectric fiber sheet; and a shape of the carbon fiber plate matrix is optimized by width change and hole digging. The propelling modules comprise a head propelling module and a tail propelling module, and the head propelling module and the tail propelling module are both propelled through a one-way valve. According to the invention, two modes of the pre-compression rib plate are adjusted through the piezoelectric fiber sheet, so that a volume of an internal cavity is changed, and jet propelling is carried out.

摘要： A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.

摘要： A personal flotation device includes a burst zipper connected to a back panel, a left panel, and a right panel of a shell of the personal flotation device. The personal flotation device further includes an inflatable bladder sewn into a seam of the shell of the personal flotation device. The seam extends through one or more of a neck panel, the left panel, and the right panel of the shell. The personal flotation device further includes strap components connected between the back panel and the left panel and the right panel. The strap components are configured to secure the left panel and the right panel to the back panel.

摘要： A method for retrieving an object exposed to a body of water. The freezing of water is a very power- and time-consuming operation and therefore, can be quite costly. To reduce at least one of these problems, an aqueous viscous mass is provided in a zone adjacent to an outer section of an object, and then the mass is frozen to the object. In some implementations, a thermal conductivity-promoting agent, such as metal, is used, among other variations.
