A vertical axis wind turbine includes a support axis and a wind wheel. The wind wheel includes a rotation base, plural rotation stand sets, plural deflection structures, plural blades, and plural deflection-limiting structures corresponding to the plural blades. The rotation base is rotatably disposed on the support axis. The plural rotation stand sets may define a rotation plane. A first end of each rotation stand set is fixedly disposed on the rotation base. Each blade is pivotally coupled to a second end of the corresponding rotation stand set through the corresponding deflection structure. Consequently, an angle of attack of the blade in an airflow is correspondingly adjusted. When one of the plural blades is deflected, the corresponding deflection-limiting structure generates a first rotational torque in a first rotating direction or a second rotational torque in a second rotating direction so as to rotate the rotation base.

A mask-oriented air filtering pad includes a base layer, a filtering layer, an airtight seal and at least two connection elements. The base layer has an outer side and an inner side. The filtering layer is disposed at the middle of the inner side. The filtering layer corresponds in outline to the human mouth and nose. The airtight seal surrounds the filtering layer and is disposed on the inner side. The at least two connection elements are disposed at two end portions on the outer side, respectively. The required area of the filtering layer is minimized, and the airtight seal tightly encloses the human mouth and nose; thus, the mask-oriented air filtering pad can save filtering materials, cut cost, reduce waste, enhance filtration, and allow the human face to feel comfortable.

A non-contact and optical measuring automation system includes a base, a rotating chuck to clamp a disk cam, a moving stage module and an optical measuring module. The moving stage module includes a first linear motion stage movably disposed on the base, a second linear motion stage movably disposed on the first linear motion stage, and a rotary motion stage rotatably disposed on the second linear motion stage. The optical measuring module disposed on the rotary motion stage includes a laser-emitting unit and an image-capturing unit. The laser-emitting unit projects a light beam onto a cam surface of the disk cam, and the image-capturing unit receives scattering light to capture a grayscale measuring image including a profile speckle pattern. A computer calculates a profile speckle characteristic value according to the grayscale measuring image and the surface roughness value according to the profile speckle characteristic value.

An improved destructive and visual measurement automation system and a method for measuring a web thickness of a microdrill are provided. When a dual-axis motion platform module moves the microdrill to a first position, a reflection module reflects a first image in a first direction toward a second direction. A vision module receives the reflected first image in the second direction and outputs the received first image to a computer. According to the first image, the computer performs a positioning procedure and a grinding procedure to drive a drill grinding module to grind the microdrill to a sectional position to be measured of the microdrill. When the microdrill is moved to a second position, the vision module outputs a second image to the computer. According to the second image, the computer performs an image computing procedure to obtain the web thickness at the sectional position to be measured.

A simple alternative to separate filamentous bodies of Monostroma latissimum algae (large green algae) as seed stock. The filamentous bodies are easily separated and prepared for cultivation. At low luminosity (50 μm mole s−1m−2), the filamentous bodies grow into the filamentous colony. If the filamentous colony is in turns irradiated at the luminosity greater than 100 μm mole s−1m−2, it is turning into fronds. Thereby the filamentous bodies are evenly distributed into small segments so as to penetrate through the cotton rope for algal mass cultivation and further grow into fronds at high luminosity.

A depth wire-controlled aquaculture device, having a net cage, float balls, a depth sensor and at least one wire control module, is illustrated. The net cage has a frame and a net body. The float balls are connected to the net cage. The depth sensor is installed on the net cage and detects an underwater depth of the net cage to generate a depth signal. The wire control module comprises a controller, a reel, a driver and a connection wire. The connection wire is connected to the net cage and wound around the reel, the controller is signally connected the depth sensor and the driver, the depth signal is transmitted to the controller, the controller controls the driver according to the depth signal, and the driver drives the reel to rotate to draw or release the connection wire, so as to change the underwater depth of the net cage.
