  • Patent number: 7072888
    Abstract: A process for refining the results of a query to an internet search engine database by the use of user feedback is disclosed. It is a method to allow a user to rate the relevancy of URLs returned for a specific query. The relevancy ratings for a specific query are combined by the internet search engine with data from a user profile of personal information defined by the user. The internet search engine can determine which items of data in the profile are common between users who have rated a query result highly. The search engine can then modify the search algorithm to return those URLs rated highly by users with common profile attributes. The benefit to the internet is more efficient searching and retrieval of information for users.

  • Patent number: 5649521
    Abstract: A crossbow for shooting projectiles includes a frame with flexible bow arms and a bowstring connecting the arms, a trigger assembly for retaining the bowstring in a cocked position and releasing to propel the projectile, and a hollow barrel with interior rifling into which projectiles are loaded and through which they are expelled. A firing bolt is connected to the bowstring and located in the barrel to transfer force from the bowstring to the projectile. In the prior art, such firing bolts contact the barrel interior, resulting in friction and wear of the rifling. In this invention, the barrel includes an elongated slot (317) therealong. The firing bolt (324) is slidably supported on rails (329) on the exterior of the barrel. The firing bolt includes a driving member (338, 327) which extends through the slot to contact the projectile, but does not contact the barrel interior walls, thus propelling the projectile without causing friction and wear within the barrel.
