  • Patent number: 8312522
    Abstract: A solution is provided for associating network traffic traversing on a networked environment according to a selected category item, such as a user name or other network entity identity-related information, by using a monitor device. The solution includes: obtaining user information from the directory service by obtaining at least one set of user object attributes from the directory service; identifying at least one authentication exchange packet from packets traversing on the networked environment; extracting a user ID and a network address from the authentication exchange packet; filtering or selecting packets traversing on the network environment that each have a network address equivalent to the extracted network address; and associating packets that were selected with user information having a name attribute equivalent to the extracted user ID.

  • Patent number: 6105191
    Abstract: A toothbrush with scraping bristles has a plural number of bristle clusters crisscrossly mounted on a block head. The tip of the bristle clusters has a contour mating with dental area. In the block head, there are provided with a scraping bristle stem which has a plural number of movable scraping bristles normally extendable out of the block head for moving to and fro in the gingiva sulcus to scrape off tartars formed on teeth surface. A plural number of spaced and triangle scraping flakes may be disposed on each scraping bristle to enhance the effect of scraping tartars and dental plaque formed in the inter-gingiva-sulcus. The toothbrush may be used manually or be driven electrically.
