Abstract: A single smart health device able to monitor all physiological aspects of a human body includes a body fluid detection module, a temperature detection module, an electrocardiogram detection module, and a control module. The body fluid detection module tests and detects amounts of biological substances in body fluids. The temperature detection module detects a temperature of the human body. The electrocardiogram detection module detects a heart rate of the human body. The control module is electrically connected to the body fluid detection module, the temperature detection module, and the electrocardiogram detection module, and obtains the detected amounts of biological substances, the detected temperature, and the detected heart rate.

Abstract: A pinwheel assembly has a main shaft, a plurality of curved rods, a first rotating wheel, a second rotating wheel, a third rotating wheel, a fourth rotating wheel, and a plurality of fabric vanes. The main shaft passes through the first rotating wheel, the second rotating wheel, the third rotating wheel, and the fourth rotating wheel. Each of the curved rods is connected to the first rotating wheel and the fourth rotating wheel. Each of the fabric vanes is connected to the second rotating wheel and the third rotating wheel.

Abstract: A pinwheel assembly has a polygonal main body, and a rotating device disposed in a center of the polygonal main body. The rotating device has a bearing and a hollow shaft. A plurality of support rods are connected to the bearing. The hollow shaft is inserted through the bearing. The polygonal main body has a plurality of diagonal lines. A plurality of through holes are formed on the diagonal lines of the polygonal main body. A plurality of triangular vanes are disposed on the polygonal main body. Each triangular vane has a triangular end bag. Each support rod is inserted in the corresponding triangular end bag and inserted through the corresponding through hole of the polygonal main body.

Abstract: A pinwheel device has a main shaft, a rotating wheel connected to the main shaft, and a first support rod, a second support rod, and a third support rod connected to the rotating wheel. A first decoration wheel is disposed on the rotating wheel. A second decoration wheel is disposed on the first support rod. A third decoration wheel is disposed on the second support rod.

Abstract: A kite has a cover sheet and a cross-shaped frame. The cover sheet has an oblong hole and four triangular corner bags. The cross-shaped frame has a spine, a two-way joint disposed on the spine, and two crosspieces connected to the two-way joint. Two rotating wheels are disposed on the spine. A plurality of rotating vanes engage with the rotating wheels. The spine is inserted in two of the triangular corner bags. Each of the crosspieces is inserted in the corresponding triangular corner bag. Two tail bands are connected to the cover sheet.
