  • Publication number: 20150028105
    Abstract: An optical component includes a substrate and two optical lenses, and the substrate and the two optical lenses are an integrated and inseparable structure. A groove that can accommodate a required collimating optical element is provided on the substrate, or a collimating optical element and the substrate are integrated. Because fabrication of optical elements is completed during fabrication of the optical component, the number of elements to fabricate and time and cost of fabricating the elements can be reduced. Also, during assembly of an image capturing device, it is only required that the optical component is locked to a body of the image capturing device to complete arrangement of a front panel and the optical elements, which can greatly simplify an assembly procedure and shorten assembly time.

  • Patent number: 8274975
    Abstract: Embodiments of the invention provide a system and method for automatically managing a network port based on a calendar function. In one embodiment, a discovery protocol is provided for automatically discovering at least one port of at least one switch in a network. Furthermore, a management protocol is provided. The management protocol is configured to automatically manage the at least one port of the at least one switch in the network based on a programmable calendar function. In addition, a reconfiguration protocol is also provided. The reconfiguration protocol is configured to reconfigure the calendar function of the automatic management of the at least one port of the at least one switch in the network.

  • Patent number: 7951386
    Abstract: This invention provides the sequence of 5,299 nucleotides from the E. canis genome. There are four proteins, ProA, ProB, MmpA, and a cytochrome oxidase homolog, as well as a partial lipoprotein signal peptidase homolog at the carboxy terminus, coded for in this cloned fragment. The antigenic properties of these proteins allow them to be used to create a vaccine. An embodiment of this invention includes the creation of a DNA vaccine, a recombinant vaccine, and a T cell epitope vaccine. Another embodiment of this invention includes the use of serological diagnosis techniques.

  • Patent number: 7781378
    Abstract: An array is formed with a protective cover on a substrate. The protective cover is patterned to produce an array of openings to the substrate. Desired material is deposited on the substrate through the openings. The protective cover may then be removed. In one embodiment, the protective cover is a conformal polymer, such as di-para-xylylene. It may be removed by mechanical peeling. The material may be biological material such as DNA. The protective cover may be used to prevent non-specific hybridization in inter-spot regions by performing hybridization with the cover still in place. Hybridization that occurs in such regions between the spots may be removed with removal of the protective cover.
