An article anti-lost device comprises a plurality of sensors and a host. Each sensor comprises a recognition module and a sensor signal transceiver module. The host comprises a control module, a host signal transceiver module, a host warning module, an operation module and a display module. In an article anti-lost method, the host and the sensor are firstly paired, and then the sensor is combined with a to-be-monitored article and a warning distance is set. When a distance between the sensor and the host exceeds the warning distance, a warning signal is outputted, and an orientation and a distance of the sensor are prompted on the host. With the structure and the method, when the article leaves the user by a predetermined distance, the user can be reminded to prevent the article from getting lost or stolen.

A zoom lens includes a first lens group having negative refractive power, a second lens group having positive refractive power and a third lens group having positive refractive power. The second lens group is disposed between the first lens group and the third lens group. The second lens group includes at least an aspheric glass lens. Through using the aspheric glass lens, the imaging quality of the disclosed zoom lens is not sensitive to temperatures changes.

An electronic device includes a housing having a lens assembly and a feeding device. The lens assembly is movable between a first reference position and a second reference position with respect to the housing. The feeding device is coupled to the lens assembly. When the lens assembly is in the first reference position, the lens assembly is engaged with the housing. When the lens assembly is moved to the second reference position from the first reference position by the feeding device, the lens assembly situated in the second reference position is rotatable and movable.

A miniature zoom lens includes a first, a second and a third lens groups arranged along an optical axis and from an object side to an image side in sequence. The refractive powers of the three lens groups are negative, positive and positive, respectively. The first lens group is fixed at a predetermined position. The second lens group is movable along the optical axis in accordance with a change of magnification. The third lens group is movable along the optical axis for keeping an image plane fixed at an image sensor. The first lens group is in resting state and the second and the third lens groups are movable during zoom-in or zoom-out operation of the miniature zoom lens. In addition, the miniature zoom lens can be composed of at least seven pieces of lens, thus the cost is reduced, the manufacture is easy and the assembly is simple.

A tooth mold retaining frame comprises an L shape seat; a pivotal block; a universal connector; a first positioning block; a second positioning block; and a first fine adjust unit. By using the first fine adjust unit, second fine adjust unit and the fine-adjust device, an upper teeth mold, and a lower teeth mold can move with respect to one another precisely. By a universal connector, the upper teeth mold can move three directionally and can lift or descend proportionally so as to avoid the error in manufacturing of the teeth mold. Thus the teeth mold can be made precisely and the condition of the teeth mold can be viewed conveniently. Furthermore, the teeth mold can be sent directly without needing to send the teeth frame. Thus, the manufacturer can make the teeth mold continuously without affecting the working time.

A composite-metal-composite sandwich structure is employed as a housing of a mobile electronic device. A metal sheet is preformed as a desired shape with nuts deposed thereon. A composite sheet is attached to each side of the metal sheet, exposing the nuts such that other components of the mobile electronic device can be screwed on the sandwich structure.

Composite-metal-composite sandwich housing structure

A printed plastic film is placed on a composite sheet material. Then, both of the printed plastic film and the composite sheet material are put in a mold. The mold is closed and heated to soften the composite sheet material, so that the composite sheet material and the printed plastic film can be attached together to form the product. After opening the mold, the product having an ornamental surface can be obtained.

Surface ornamentation method of composite material

An apparatus for making a printed spring-roll skin includes a forming drum having a circumferential heating surface to form a skin from dough, a dough feeder having an outlet adjacent to the heating surface, a scraper disposed adjacent the heating surface to remove the skin from the heating surface, and a printing roller disposed rotatably adjacent the forming drum and having a circumferential printing surface in contact with the heating surface. First and second intermeshed gears are respectively disposed coaxially with the forming drum and the printing roller so as to drive the same simultaneously. A coloring agent is supplied to the printing roller to print the drum surface which transfers a print to the skin.
