Abstract: An electronic device includes a monitor stand, a hinge mechanism, and an operation element. The hinge mechanism includes a back plate, a speed reduction assembly, and a friction assembly. The back plate is fixed to the monitor stand. The speed reduction assembly includes an input plate and a speed reduction member. The speed reduction member is arranged on the input plate. The friction assembly is arranged between the back plate and the input plate. The operation element is connected to the speed reduction member. A rotation center of the operation element coincides with an axis of the back plate and the speed reduction member are coaxially arranged.

Abstract: The present invention relates to a coral composite extract, a composition including the same and a method of producing the same. The coral composite extract includes at least two briarane-type diterpenoid compounds from corals of Briareum violaceum, B. excavatum and B. stechei, thereby being applied as an effective ingredient of a skin external use composition, a cosmetic composition and a medicinal composition.

Abstract: A piezoelectric energy hunting device and a voltage signal application system thereof are disclosed. The piezoelectric energy hunting device includes a plurality of curved piezoelectric elements, a plurality of rigid foams, and a flexible foam structure. The plurality of curved piezoelectric elements are arranged side by side with one another, wherein each curved piezoelectric element is attached to one of the rigid foams. The flexible foam structure includes a top foam and a bottom foam covering the outer surface of the plurality of curved piezoelectric elements and the plurality of rigid foams; when the flexible foam structure is compressed, the plurality of curved piezoelectric elements are simultaneously deformed, thereby generating a voltage signal. When the flexible foam structure is not compressed, the flexible foam structure and the plurality of rigid foams provide an elastic force to restore the plurality of curved piezoelectric elements.

Abstract: Disclosed herein is a method for prolonging analgesic effect of a membrane permeable local anesthetic in a subject in need thereof. The method uses cinnamaldehyde as an adjuvant which, when administered prior to or simultaneously with the administration of a local anesthetic, prolongs the analgesic effect of the local anesthetic. Also disclosed herein is a method for providing analgesic effect in a subject in need thereof. The method uses cinnamaldehyde as an analgesic compound which, when administered alone to the subject in an analgesically effective amount, provides the analgesic effect.
