A block magnification ratio is adjusted according to the block group and a block magnification box. The block group in the block magnification box is enlarged according to the block magnification ratio. The picture is cropped to obtain an object. A picture magnification ratio is adjusted according to the object and a picture magnification box. The object in the picture magnification box is enlarged according to the picture magnification ratio.

Abstract: An underneath large-capacity single-gas-pump foam generating device includes a liquid replenishment mechanism and a foam generating mechanism. The liquid replenishment mechanism includes a liquid replenishment groove and a liquid replenishment bottle. The liquid replenishment bottle has a bottle opening sleeved in the liquid replenishment groove. The foam generating mechanism includes a gas supply pump unit, a gas mixing groove cavity, a gas-liquid mixing structure, a gas inlet and a vent valve structure. A lower portion of the gas mixing groove cavity is communicated with a lower portion of the liquid replenishment groove, a liquid replenishment one-way valve is arranged between the gas mixing groove cavity and the liquid replenishment groove. The gas-liquid mixing structure is provided with a liquid outlet channel, a gas outlet channel and a mixing channel, an inlet end of the liquid outlet channel extends downwardly into a bottom portion of the gas mixing groove cavity.

Abstract: A self-powered wireless computer mouse utilizes the direct piezoelectric effect to generate electricity. When a user uses the mouse, a flexible flat portion and a piezoelectric element may be deformed or pressed against and the piezoelectric element may convert such mechanical stress into voltage. In addition, the computer mouse can eliminate the need for battery or other power supply means and can supply electricity by itself; therefore, the computer mouse can bring about the advancement of the computer mouse manufacturing industry.
