  • Touchless fingerprinting acquisition and processing application for mobile devices
    Patent number: 9672406
    Abstract: This disclosure is of a biometric authentication system and method. The system includes a mobile device having a camera and a screen, and a database. The system is programmed to superimpose on the screen an overlay of a finger over a real-time image seen by the camera, capture an image of a fingerprint of a user with the camera, compare the captured image with an authenticated fingerprint image that is stored in the database, and return a positive result if the compared images match.

  • Toggle suture handling means and method
    Patent number: 5474573
    Abstract: Disclosed is a method of suturing the abomasum of a ruminant animal. The method includes inserting one end of a cannula through the belly of the animal and into the lumen of the abomasum. One end of a suture and toggle attached thereto is inserted through a bore of the cannula and into the lumen by travel of a trocar through the bore behind the toggle. The extent of the travel of the cannula into the lumen is limited by providing an outer end of the cannula with a flange that engages the hide of the animal and the travel of the trocar through the bore of the cannula is limited by providing the trocar with a handle that abuts against the flange of the cannula.
