  • Patent number: 7818984
    Abstract: An electronic door locking apparatus having a mortise lock including dead bolt and latch bolt installed therein, which is able to easily open a door from the outside by inserting a metal card having a magnet installed inside if a power source such as a dry battery is not supplied or if the locking apparatus is not useable due to other mechanical defects, and also able to perform a lock function since a dead bolt is locked if a door handle of an outer unit is rotated upwards when there are defects in a driving motor or electronic components.
    Type: Grant

  • Patent number: 7266226
    Abstract: A fingerprint recognition apparatus is provided. A user's finger brings into contact with both a fingerprint recognition module and a touch switch conductor by installing the touch switch conductor on the front surface of the fingerprint recognition module. By signal generated from the touch switch conductor sensing the user's finger without any preliminary action, a power-supplying unit supplies a power to the fingerprint recognition module. Therefore, the fingerprint recognition apparatus is simplified in its use.

  • Patent number: 7023319
    Abstract: A door lock handle. The door lock handle having a fingerprint recognition module comprises a handle body having an installing groove with a designated size so as to installing the fingerprint recognition module, a handle cover having an exposing groove corresponding to the installing groove so as to expose a fingerprint recognition plate of the fingerprint recognition module installed on the handle body, a switch hole formed by perforating a part of the handle body, and a protruded conductor installed on the switch hole, the conductor serving to sense the grip of the door lock handle of the user. Herein, the conductor is electrically connected to a touch switch circuit mounted on a door lock controlling unit, and the touch switch circuit senses the grip of the door lock handle by the user and provides the sensed signal to the door lock controlling unit.

  • Patent number: 6374652
    Abstract: A locking doorknob which recognizes a fingerprint, in which the detecting sensor of a fingerprint is installed on the spot of the doorknob that a thumb or other fingers are placed naturally as the door is being opened. The location of the detecting sensor of the fingerprint can be changed at the discretion of a user to correspond to such a location. During operation, as soon as a user holds the doorknob, his fingerprint is measured and searched, and if the fingerprint corresponds to a fingerprint previously input, the door is unlocked and the doorknob can be turned to open the door. In this way, fingerprint recognition and opening of the door are performed at the same time.
