The present invention discloses an electromagnetic air pump including an air chamber operable to be compressed or expanded. The air chamber is defined by a platform surface and a rubber cap operable to be pressed downward. The rubber cap includes a support and a cover. During the operation of the electromagnetic air pump, the cover is configured to bear against the support with the platform surface when the cover is pressed downward. When the air chamber is compressed or expanded, each pair of geometrically symmetrical parts of the cover corresponds to a pair of displacement changes relative to the platform surface, wherein a difference between the pair of displacement changes is not greater than 5%. Thus, the rubber cap is provided with an effect of a substantially uniform stress.

The AI circuit at least receives the inputting signal from the signal generating circuit, receives the environment information from the environment detecting circuit, receives a first performance information from the memory array, receives a second performance information from the AI circuit and outputs an ideal signal to the memory array according to the inputting signal, the environment information, the first performance information and the second performance information.

Memory device and intelligent operation method thereof

The semiconductor structure includes a semiconductor device, a first metallization layer on the semiconductor device, a second metallization layer on the first metallization layer, and a third dielectric layer between the first metallization layer and the second metallization layer. The first metallization layer includes a first dielectric layer and a first metal layer disposed in the first dielectric layer, wherein the first metal layer has a first thickness, and the first metal layer comprises copper. The third dielectric layer has a second thickness, and a ratio of the second thickness of the third dielectric layer to the first thickness of the first metal layer is ranged from about 3 to about 20.

Semiconductor structure and method of fabricating wiring structure

A charging base has a bottom case, a printed circuit board (PCB) and a top case. The bottom case includes at least one drainage hole. The PCB is mounted in the bottom case and includes a mounting hole, a positioning block and charging terminals. The positioning block is attached to the PCB and has through holes. The charging terminals are secured to the positioning block and have apertures. The top case covers the bottom case and includes terminal holes and a top enclosed wall. The top enclosed wall is secured around the positioning block. Therefore, when water accidentally enters the charging base via the terminal holes, the water will sequentially flow through the apertures of the charging terminals, the through holes of the positioning block and the mounting hole of the PCB and subsequently drain out of the drainage hole of the bottom case.

Charging base with drainage features

A power adapter having a replaceable and positionable plug has a body and a plug. The body has two conducting terminals and a ground terminal mounted on a top of the body. The plug has a ground hole and multiple arced holes mounted through a bottom thereof, an intermediate ground assembly and two intermediate conducting clip assemblies mounted in the plug and respectively corresponding to the ground hole and the arced holes, and a ground pin and two conducting pins mounted on a top thereof and respectively and electrically connected with the intermediate ground assembly and the intermediate conducting clip assemblies. When the plug is assembled with the body, the ground terminal and the conducting terminals are electrically connected with the ground pin and the conducting pins respectively inserted into the ground hole and selectively into the corresponding arced holes. With the structure, the plug is replaceable and positionable.

Power adapter having a replaceable and positionable plug

A power adapter having a replaceable and rotatable plug has a body having an annular chamber, two conducting elements inside the annular chamber, four channels recessed on a top thereof to communicate with the annular chamber, and an engagement slot abutting each of the four channels; and a hollow plug having two intermediate conducting elements, a cylinder protruding beyond a bottom of the plug and received in the annular chamber, four arced holes communicating with an inner portion of the plug, four engagement blocks protruding from a cylindrical periphery to respectively correspond to the four channels and four engagement slots, and at least two prongs mounted on a top thereof, one end of each of the two prongs penetrating through the plug to electrically connect with corresponding intermediate conducting elements. Given the aforementioned structure, the plug can be replaced and selectively oriented with respect to the body.
