Abstract: A high security computer system and method that authenticates a user using iris recognition and liveliness detection. The method for authenticating the user to the secure system includes capturing an image of the user's face and generating an iris template from the image. While the iris template is being generated, liveliness verification is performed on the user's face. User access is granted if the iris template matches the enrolled iris template and if the liveness verification demonstrates the user's face is live, and denied if otherwise. The method may optionally silently re-authenticate the user after access is granted to the secure system. The authentication system includes an image capture device for capturing an image, an iris template generation component to generate an iris template from the image, a liveness detection component, and an iris comparison component adapted to compare the iris template to iris templates of previously enrolled users.

Abstract: An intraocular device including a prism and shift amplifier is provided. Also provided is a system containing the intraocular device, and a method for improving vision of a person with central vision loss. The method involves implanting the intraocular device in the person so that the prism and shift amplifier cumulatively shift a retinal image away from the fovea of an eye to a functional retinal portion of the eye. Also provided is a method for correcting a binocular misalignment of a person using the intraocular device.

Abstract: A mobile biometric identification system and method provided in a small mobile housing. The system and method provide rapid determination of identity, or in the alternative, rapid determination of whether an individual's identification information is in a particular database, for example, by iris recognition. The system and method return one of a small number of easily recognizable results, such as “Not Known”, “Known Friendly,” and “Known Unfriendly” by illumination of various LEDs. The configuration and meaning of the LEDs may be customized to a particular application.

Abstract: A prism device includes: a prism material having substantially the same index of refraction at first and second wavelengths; a first anti-reflection coating for reducing reflection of a first signal beam at the first wavelength; and a second anti-reflection coating for reducing reflection of a second signal beam at the second wavelength. The prism material can be silicon, which has substantially the same index of refraction at IR and RF wavelengths. In this case, the RF anti-reflection coating can be a layer of silicon dioxide (fused silica), which can be sandwiched between two IR anti-reflection coatings designed to minimize IR reflections between the surrounding air and the RF anti-reflection coating and between the RF anti-reflection coating and the prism material, respectively. Two or more of the prism devices can be used in a beam steering system to simultaneous direct the first and second signal beams in substantially the same direction.
