Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: A camping stove includes a pair of bases pivotally coupled together, the bases can be opened and fixed in parallel to each other for cooking food, and the bases can be folded to a compact configuration for facilitating transportation purposes. A pair of legs are coupled to the bases for supporting the base when the bases are opened, the legs form a handle for carrying the camping stove when the bases are folded. The burning device includes a board having a number of air holes for uniformly distributing gas.
