Abstract: An electronic timepiece includes, a first substrate that includes a plurality of first connection terminals, a processor, and a selector that switches a connection between the first connection terminals and the processor, and a second substrate that includes a plurality of second connection terminals that are connected to a plurality of peripheral devices that each perform a certain operation. Each of the second connection terminals is connected to each of the first connection terminals. The selector switches the first connection terminal that is connected to the processor based on control by the processor.

Abstract: A magnetic-field-adjustable micromagnetic orthodontic accelerator includes a cheek side plate, a tongue side plate and a supporting plate to form a structure of teeth sleeves, cheek side magnets and tongue side magnets are arranged on the cheek side plate and the tongue side plate respectively, the cheek side magnets and the tongue side magnets form a micro magnetic field environment around roots of to-be-moved teeth receiving orthodontic treatment, physiological magnetic field loss caused by traction of the orthodontic accessory is effectively compensated, metabolism and reconstruction of periodontal tissue of the to-be-moved teeth are promoted, and the orthodontic teeth moving process is accelerated.

Abstract: A micro-magnetic invisible orthodontic appliance is provided. The micro-magnetic invisible orthodontic appliance includes a bottom brace (1), an outer periodontal brace (2) and an inner periodontal brace (3). The bottom brace (1), the outer periodontal brace (2) and the inner periodontal brace (3) together form a U-shaped brace. A tooth receiving groove is defined between the outer periodontal brace (2) and the inner periodontal brace (3). The bottom brace (1), the outer periodontal brace (2) and the inner periodontal brace (3) are made from one of a polymer composite material, biological ceramic, and an interpenetrating polymer network material, dispersed with permanent magnetic neodymium-iron-boron powder, by one-piece molding or three-dimensional printing.

Abstract: A micro-magnetic integrated orthodontic bracket, a flexible magnetic patch and a preparation method thereof are provided. The micro-magnetic integrated orthodontic bracket includes a base body and an arch wire groove disposed on the base body. The arch wire groove is used for threading an arch wire. Under normal orthodontic treatment, the micro-magnetic integrated orthodontic bracket is normally disposed on a buccal side of a tooth, and its front side is normally arranged with the arch wire for force exertion to carry out the orthodontic treatment. And the micro-magnetic integrated orthodontic bracket serves as a carrier to bear the orthodontic treatment force generated by the arch wire.
