A USB device includes a base, a circuit board disposed on the base and having front-end and rear-end portions and a ground circuitry, an upper cover, solder points, a switch and a button mount. The rear-end portion is used for inserting into a connection port of a computer terminal. The upper cover covers the front-end portion and has an opening. The solder points are formed on the front-end portion and coupled to the ground circuitry. The switch having a metal cover is soldered to the solder points for controlling wireless connection between the computer terminal and an external device. The button mount is movably disposed through the opening and sleeves the front-end portion for triggering the switch. An electrostatic discharge entering from the opening can pass through a first guide hole of the button mount and is conducted to the ground circuitry via the metal cover and the solder point.

A CMOS single chip includes a movable film, at least one support pillar, a base metal layer and a circuit integration. The movable film is disposed on a top layer of the CMOS single chip and has a plurality of through-vias. The support pillar is disposed under the movable film to provide a supporting force of the movable film. The base metal layer is formed under the support pillars and isolated from the support pillars, and faces towards the movable film to form a micro capacitor to sense one of the outside sensing signals. The area of the base metal layer is larger than the area of the movable film. The circuit integration is formed under the base metal layer, or formed under the base metal layer and on the side of the movable film, and connected to the movable film and the base metal layer.

The present invention disclosed a micro acoustic collector and CMOS microphone single chip. The micro acoustic collector comprising: a plurality of leaf-shaped structures annularly arranged with symmetry, each of the plurality of leaf-shaped structure having a suspended arm and a restrained arm, and the suspended arm of the plurality of leaf-shaped structures connected to a suspended fulcrum, and a plurality of through-vias formed in the suspended fulcrum and the plurality of leaf-shaped structures; a plurality of support pillars uniformly disposed under edges of the plurality of leaf-shaped structures corresponding to the restrained arms and the suspend arms; and a base metal layer formed under and insulated from the plurality of support pillars, and facing towards the inner-annular-supported acoustic collection film to form a hollow space.

The present invention disclosed a micro acoustic collector with a lateral cavity, comprising: a base metal layer; a movable film, an annular side wall; a lateral metal layer. The movable film faces towards the base metal layer to form a hollow space. The lateral metal layer is formed at a side of the movable film and around the movable film, fixed by the annular side wall and spaced apart from peripheral of the movable film by a distance, and the lateral metal layer faces towards the base metal layer to form a lateral cavity to assist an acoustic collection.

A premix composition includes polyether polyol and a blowing agent, wherein the polyether polyol is a copolymer of propylene oxide and trimethylolpropane, a copolymer of propylene oxide, ethylene oxide and trimethylolpropane, a copolymer of propylene oxide, ethylene oxide and glycerol, or combinations thereof. A foaming composition which is obtained by mixing the premix composition with diisocyanate.

A brewing apparatus for an electric coffee maker includes a sleeve unit and a plunger unit disposed horizontally and movably within a base. Firstly, when a large chamber is defined within the sleeve unit between the plunger unit and a water-feeding unit, ground coffee beans can be fed into the large chamber via an opening in the sleeve unit. Subsequently, when the sleeve unit and the plunger clamp the ground coffee beans, hot water can be fed into a small chamber defined within the sleeve unit between the plunger unit and the water-feeding unit, thereby resulting in consumed ground coffee and brewed coffee that exits from the plunger unit. Finally, when the sleeve unit is separated from the plunger unit, the consumed ground coffee drops from a space defined between the sleeve unit and the plunger unit.
