Provided are a self-cleaning air filtering material and a preparation method therefor. The air filtering material comprises: a submicron fiber layer (2) at an inflow surface for surface filtration, a supporting area (3) for supporting and a mixed area (5) between the submicron fiber layer (2) and the supporting area (3), wherein the mixed area (5) is formed by contacting and mixing part of the fibers in the submicron fiber layer (2) and the supporting area (3) with each other during the one-step formation of the submicron fiber layer (2) and the supporting area (3) by passing through a double-layer headbox.

A hazard warning device for vehicles is provided, including a light source unit, a light guiding unit, a warning structure unit and a control unit. The light source unit generates a light source for warning. The light guiding unit guides the light source to become a surface light source having an area. The warning structure unit scatters or reflects the surface light source and displays a warning. The control unit is the element for controlling the on and off of the light source unit. When the control unit receives an activation signal from a vehicle, the control unit activates the light source unit and displays a warning on a surface area of the vehicle through the light guiding unit and the warning structure unit.

A projector includes at least one light source module, an optical system, an imaging unit, and a projection lens. Each light source module includes a lamp unit and a heat-dissipating module in close contacting with the lamp unit. Each of the at least one light source module is positioned at one end of the optical system. The imaging unit is positioned at the other end of the optical system. The projection lens is positioned at the same end of the optical system with the imaging unit. Each lamp unit can be adjusted along a first direction relative to the heat-dissipating module, each light source module can be adjusted along a second direction relative to the optical system, the first direction and the second direction both perpendicular to the light emitting direction of the corresponding lamp unit.

A document snapshot device is provided. The document snapshot device comprises a baseboard, a camera and a foldable supporting means. The baseboard comprises a central area to place a document and a connecting chamfer. The camera comprises a pivot. The foldable supporting means comprises a first supporting means connecting the connecting chamfers, a second supporting means connecting the pivot of the camera and a third supporting means connecting the first and the second supporting means. The first, second and third supporting means can stretch along a first plane to form a first angle between the first and the third supporting means and a second angle between the second and the third supporting means. The camera can rotate along a second plane with the pivot to form a third angle relative to a stretching direction from the second supporting means to the camera to aim at the document to take a snapshot.
摘要:
A long-term antibiotic and deodorant textile with mesoporous structure and processing method thereof are provided. At first, a textile is dipped into an aqueous solution of a surfactant containing nanoparticles. An aqueous solution of a silicon source is prepared and its pH value is adjusted to about 5˜9. Then, the aqueous solution of the surfactant and the aqueous solution of the silicon source are mixed to form a mixture solution. The mixture solution is stirred until silica powder form therein. The textile is taken out and dipped into water and organic solvent separately several times. Finally, the textile is dried to obtain the long-term antibiotic and deodorant textile with mesoporous structure.

A multimedia player is disclosed, including a base, a cover rotatably disposed on the base, an engaging mechanism disposed on the base, an elastic element connecting the base and the cover, and a carrier disposed on the cover to carry a media source. When the cover is closed to cover the base, the cover engages the base with the engaging mechanism, and the elastic element is biased to store an elastic potential and when the cover is released from the engaging mechanism, the elastic potential is released to open the cover.

A computerized data management method and a computerized data management system using the same are provided. The computerized data management method is used for encrypting/decrypting a digital data of an electronic device. The computerized data management method comprises the following steps. Firstly, a user's facial characteristic is captured. Next, whether the user's facial characteristic matches with an encrypting-permission user's facial characteristic stored in a database is determined in an encrypting process. If the user's facial characteristic matches with the encrypting-permission user's facial characteristic stored in the database, then the user is allowed to encrypt a digital data. Then, whether the user's facial characteristic matches with a facial characteristic of a decrypting-permission user corresponding a digital data is determined in a decrypting process. If the user's facial characteristic matches with the facial characteristic of the decrypting-permission user corresponding the digital data, then the user is allowed to decrypt the digital data.
摘要:
A polishing pad, comprising a mounting surface and an opposing polishing surface with a polishing pattern having at least one aperture thereon, is formed with an adhesive layer adhered to the mounting surface with uniform adhesive strength therebetween. Embodiments include applying an adhesive layer to the mounting surface with uniform pressure prior to forming the polishing pattern on the polishing surface. Embodiments also include forming the polishing pattern having at least one aperture, forming a fitter having a surface pattern opposite to the polishing pattern and having a projection, positioning the fitter on the polishing pattern so that the projection fills the aperture in the polishing pattern forming a composite having substantially parallel opposing surfaces, applying pressure to bond the adhesive layer to the mounting surface with substantially uniform adhesive strength therebetween, and removing the fitter.
