  • Patent number: 11985152
    Abstract: Systems and methods for detecting application behavior using network traffic are described herein. The systems and methods enable a network to utilize network traffic data to determine various metrics and behavioral patterns associated with applications and their use. The patterns can be used to monitor traffic from a specific user device and across the network. Further, the information may be used to generate a trust score that provides a network and/or a user with information relating to an application.

  • Publication number: 20120176666
    Abstract: This invention relates generally to laser systems that produce UV light and their methods of use. The phase matching of the conversion process has a broad temperature bandwidth so that precise temperature stabilization is not necessary to obtain a stable efficiency and a non-deformed laser beam with fast power modulation at high energies.

  • Patent number: 7084986
    Abstract: A system is used for contactless measurement of the optical imaging quality of an eye with an interferometer by which at least one light pulse with a short coherence length is coupled into the eye from a light source. The optical path length of at least one arm of the interferometer is varied for measuring the length of the eye until a typical interference pattern between a reflection of the cornea and a reflection of the retina of the eye occurs in a detector. This interference pattern together with a known path segment of the variation of the optical path length allows conclusions to be made about the length of the eye. The variation of the optical path length is carried out by introducing at least partially optically transparent elements and by at least one element of the interferometer which is movable in a defined manner in at least one of the light paths of the interferometer.

  • Publication number: 20040061830
    Abstract: A system (1) is used for contactless measurement of the optical imaging quality of an eye (2) with an interferometer (3) by which at least one light pulse with a short coherence length is coupled into the eye (2) from a light source (10). The optical path length of at least one arm (17) of the interferometer (3) is varied for measuring the length of the eye (2) until a typical interference pattern between a reflection of the cornea (4) and a reflection of the retina (6) of the eye occurs in a detector (4). This interference pattern together with a known path segment of the variation of the optical path length allows conclusions to be made about the length of the eye (2). The variation of the optical path length is carried out by introducing at least partially optically transparent elements (22) and by at least one element (19) of the interferometer (3) which is movable in a defined manner in at least one of the light paths (17) of the interferometer (3).
