    摘要: A password-less method for authenticating a user includes capturing one or more images of a face of the user and comparing the one or more images with a previously collected face template. Randomly selected colored light and randomized blinking patterns are used to capture the images of the user. Such captured images are compared to previously collected face templates, thereby thwarting spoof attacks. A secret image, known only to the user and the device, is moved from one area of the display to another randomly selected area, using the movements of the user's head or face, thereby providing a Turing based challenge. Protected audio video path (PAVP) enabled devices and components are used to protect the challenge from malware attacks.

    摘要: The present invention relates to molecules, particularly polypeptides, more particularly immunoglobulins (e.g., antibodies), comprising a variant Fc region, wherein said variant Fc region comprises at least one amino acid modification relative to a wild-type Fc region, which variant Fc region binds FcγRIIIA and/or FcγRIIA with a greater affinity, relative to a comparable molecule comprising the wild-type Fc region. The molecules of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection. The molecules of the invention are particularly useful for the treatment or prevention of a disease or disorder where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by FcγR is desired, e.g., cancer, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.

    摘要: The present invention discloses a large-field unit-magnification projection optical system. The optical system includes an optical axis, a spherical concave reflection mirror; a lens group with positive refracting power arranged adjacent the mirror with an air space therebetween. The lens group includes a first plano-convex lens, a negative meniscus lens adjacent the plano-convex lens, a positive lens adjacent the negative meniscus lens, a negative double-convex lens spaced apart far from the positive lens, and a second plano-convex lens. The optical system further includes a pair of prisms each having respective first and second surface. The second surfaces are arranged adjacent the flat surface of the plano-convex lens element on opposite sides of the optical axis and the first surfaces are arranged adjacent object planes and image planes, respectively. Each lens in the lens group and the pair of prisms provide chromatic aberration correction in a spectral region that contains at least g, h and i-line wavelengths. In this projection optical system, the object plane is parallel to the image plane.

    摘要: The present invention is directed to diabody molecules and uses thereof in the treatment of a variety of diseases and disorders, including immunological disorders, infectious disease, intoxication and cancers. The diabody molecules of the invention comprise two polypeptide chains that associate to form at least two epitope binding sites, which may recognize the same or different epitopes on the same or differing antigens. Additionally, the antigens may be from the same or different molecules. The individual polypeptide chains of the diabody molecule may be covalently bound through non-peptide bond covalent bonds, such as, but not limited to, disulfide bonding of cysteine residues located within each polypeptide chain. In particular embodiments, the diabody molecules of the present invention further comprise an Fc region, which allows antibody-like functionality to engineered into the molecule.
