  • Publication number: 20130070977
    Abstract: A contactless, three-dimensional fingerprint scanner apparatus, method, and system are described. The contactless fingerprint scanner can provide either, or both, topographical contrast of three-dimensional fingerprint features and optical contrast of a three-dimensional fingerprint surface. Data captured from scanning of a target with known geometric features mimicking fingerprint features can be examined as images or surface plots and analyzed for fidelity against the known target feature specifications to evaluate or validate device capture performance as well as interoperability. The target can be used by scanner vendors and designers to validate their devices, as well as to perform type certification.

  • Publication number: 20100098861
    Abstract: Disclosed is a method of coating carbon nanotube-reinforced plastic, which enables higher productivity and cost reduction by omitting one or more steps as compared to a conventional coating process, and which allows a paint film to be superior in adhesion and brilliance. The inventive method includes: a plastic-forming step for forming a plastic article to be coated from a plastic material mixed with a minute quantity of nanotubes; a pre-treatment step for removing oil-fat and foreign matters from the plastic article; and a surface coat coating step for coating the plastic article with paint directly on the surface of the plastic article so as to protect the plastic article.

  • Publication number: 20050023403
    Abstract: A speed reduction mechanism is provided to a strap supporting post having a winding mechanism capable of automatically winding a strap around it; the reduction mechanism includes a rotary member turnable together with the winding mechanism, and a stationary member secured to on top of the post; the rotary member has rubbing bars pivoted to a middle part thereof; the rubbing bars are biased towards the middle part by tension springs; centrifugal force will act on the rubbing bars when the winding mechanism rotates after the strap has been released from stretched position; the rubbing bars are pivoted towards the stationary member when speed of rotation of the winding mechanism is so high that the centrifugal force is greater than force of the tension springs, thus slowing down rotation of the winding mechanism, and preventing the free end of the strap from swing too fast.

  • Patent number: 6659410
    Abstract: A leg of a table includes a connecting portion, and an elongated supporting portion. The connecting portion includes two lateral plates secured to bottom of a table's top, and several horizontal portions formed between the lateral plates. The horizontal portions have through holes aligned with each other. Annular walls are formed around the through holes. The annular walls are shaped such that the inner sides thereof taper off towards an upper end of the inner side of the uppermost one. The elongated supporting portion has pads on an upper end, of which the outer sides taper off towards an upper end. The elongated supporting portion is joined to the connecting portion with the pads being inserted into the annular walls; thus, the pads will be forced further into the connecting portion when more weight is placed on the table, making the table more steady.
