    Abstract: A detection system is disclosed herein, the detection system includes a first detection device. The first detection device operates at a first operating power to capture a first image data. Wherein, when the first detection device determines there are differences between a plurality of first frames in the first image data, the first detection device switches to operate at a second operating power to capture a second image data, and the first operating power is less than the second operating power. And the first detection device determines whether the second image data matches an identification data to generate a determining result, and generates a notification signal according to the determining result.

    Abstract: A circuit board is applied to be inserted an expansion card, the expansion card includes a positioning part. The circuit board includes a board body, a slot, a release structure and a transmission mechanism. The slot is disposed on the board body. The release structure is movably disposed beside the slot along a first direction, and includes a first inclined surface and a blocking portion for limiting the positioning part. The transmission mechanism includes a linkage part and a forcing part which are linked with each other. The linkage part is connected to the release structure. When the forcing part receives an external force, the linkage part moves to move the release structure to the first direction, and releases the limitation of the positioning part by the blocking portion.

    Abstract: A three-dimensional electronic component includes a first surface, a second surface, a third surface, and a fourth surface, and an antenna structure. The antenna structure includes a first radiating metal portion, a second radiating metal portion, an adjusting metal branch, a first ground connection portion, a second ground connection portion, a feed point, and a ground point. The first radiating metal portion on the first surface extends to the second surface. The second radiating metal portion on the first surface extends to the third surface. A gap is between the first radiating metal portion and the second radiating metal portion. The adjusting metal branch on the first surface is connected to the first radiating metal portion. The feed point on the first radiating metal portion is close to the gap. The ground point on the second radiating metal portion is close to the gap.
