Abstract: An electronic device includes a protection mechanism, a first circuit board having a first electronic loop, and a second circuit board having a second electronic loop. The protection mechanism is disposed between the first circuit board and the second circuit board, and includes a frame and a first flexible board. The first flexible board includes a first connector, and a first wire mesh used for forming a third electronic loop. When trace breaking occurs to any one, any two, or all of the electronic loops, the first, the second, and the third electronic loops are forced to break, thereby protecting data saved in the electronic device from being read inappropriately, so as to avoid data to be stolen.

Abstract: A low temperature ultrasonic extraction method for plants includes the steps grinding a plant material to obtain plant pieces; immersing the plant pieces in low temperature water for a predetermined time; processing the plant pieces with ultrasonic in the low temperature water to obtain a low temperature extract liquid; and filtering the low temperature extract liquid to remove plant fibers from the extract liquid.

Abstract: An assembly of communication card in name card style has an upper and a lower metallic lid extended from its two opposite sides downward to form a plurality of protuberant teeth having respective rectangular choke holes. The protuberant teeth are put into through holes in cantilevers on side of a fixing base. A check bar provided with a plurality of choke teeth having jutting hooks and recessed snap portions penetrates through lateral holes in the cantilevers horizontally for being fastened, then the check bar is pushed forward to retain those metallic lids on the fixing base. On the contrary, a user is suggested to push the check bar backward then use a simple tool to dismount the communication card structure.
