Abstract: Underwater Deployable Structures (UDSs) capable of achieving inflation via mechanical pumps, moisture-activated expanding foams, water swelling material, or a hybrid of a mechanical pump and water swelling material. Moisture expanding foams begin as polyurethane-based resins of low viscosity, and react in the presence of water to become solid foam. In their final forms, the foams exist as open- or closed-cell, and vary in strength, elasticity, and rigidity. Water swelling material is also disclosed wherein the water swelling material is capable of achieving expansion numerous (e.g., up to about 250) times its initial volume when in contact with water and can shrink back to its initial volume upon dehydration, making the UDSs reusable. A mechanical pump may optionally be used to assist in initial inflation until the water swelling material reaches full expansion.

Abstract: The present disclosure relates to the technical field of wood preparation, and in particular, to a method and device for preparing a magnetic bamboo wood. A technical problem to be solved in the present disclosure is that: Lignin in a wood will affect the soaking efficiency of the wood during soaking of the wood. In the present disclosure, sodium hydroxide and sodium sulfite in a ratio of 2:1 are put into the soaking bucket in sequence through the high-precision powder weighing equipment and are fully dissolved in distilled water to obtain a solution, so that the solution reacts with the lignin in the bamboo wood to elute the lignin, which increases the porosity of the bamboo wood, improves the soaking efficiency, and improves the magnetism of the bamboo wood.

Abstract: A regulator circuit is presented. The regulation circuit (530) has a regulation switch (131), a voltage comparator (537) with predetermined offset voltage and an adjuster. The regulation switch (131) has a first terminal coupled to a current source (132), a second terminal connectable to a load (110), and a control terminal. The voltage comparator (537) compares a sum voltage of the offset voltage added to a voltage at the second terminal with a control voltage at the control terminal, and generates a comparison signal. The adjuster adjusts the voltage at the second terminal based on the comparison signal to control a difference voltage between the control terminal and the second terminal of the regulation switch and to maintain the regulation switch operating in a desired region of operation.

Abstract: A preparation method for nano titanate, nano titanic acid, and nano TiO2. A Ti—T intermetallic compound, as a titanium source, is reacted with an alkaline solution under ambient pressure at a temperature near the boiling point of the alkaline solution, enabling the efficient preparation of titanate nanofilm materials under normal pressure. On this basis, it is possible to economically produce titanic acid nanofilm materials and TiO2 nanosheet/powder. In combination with subsequent high-temperature and high-pressure reaction, titanate nanotubes, titanic acid nanotubes, and TiO2 nanotubes/rods can be efficiently prepared.

Abstract: A method and a system for simultaneously realizing current sampling gain and delay compensation. A dummy load is formed from three-phase inductors with star connection to replace a motor load, and a dummy rotation angle is generated by software. In a calibration mode, a standard current sampling element is used for current sampling, and the related calibration parameters in the stable state are stored. Then, in a regulation mode, other current sampling elements produced in batches are used for current sampling, and the delay compensation coefficient and gain compensation coefficient of the sampled current are generated through two closed-loop voltage feedbacks respectively, and the two compensation processes are decoupled from each other and do not affect each other. The present disclosure effectively ensures the accuracy and consistency of current sampling.
