Abstract: A detection device, which is used with a mobile electronic device having an image capturing unit, is provided. The detection device includes a plasma generation unit and a light decomposing unit. The plasma generation unit generates plasma from a sample. The light decomposing unit decomposes light emitted by the plasma for spectral analysis. The mobile electronic device receives and analyzes the light decomposed by the light decomposing unit to determine whether an element exist in the sample.

Abstract: A latching structure of a mobile electronic device includes a button module, at least one lock pin, at least one linking rod, and at least one hook module respectively disposed in a base and a display of the mobile electronic device. One end of the linking rod is coupled to the button module and another end of the linking rod is coupled to the hook module. When the button module is pressed, the button module drives the linking rod to force the hook module to release the lock pin so as to allow the user opening the display from the base of the mobile electronic device.

Abstract: A fastening mechanism suitable for being assembled into a device having a housing is provided. The fastening mechanism includes a post, a latching element, at least a plunger assembly, and an operating element. The latching element has at least an opening, the plunger assembly is disposed at a side of the latching element, and the operating element is in contact with the latching element. The post passes through the opening and presses against the plunger assembly and the post is confined by the latching element when the operating element is in a locking position. The operating element drives the latching element to move horizontally relative to the latching element so as to release the post from confinement and the plunger assembly moves vertically relative to the latching element so as to push the post out of the opening when the operating element moves to an unlocking position.
