Title: Cryptographic key generation using biometric data
Inventor: BJORN VANCE
IPC: G06K9/00
Filed: 1998-11-13
Granted: 2000-12-11
Abstract: A method and apparatus for generating a cryptographic key using biometric data is provided. A fingerprint is received, and features are extracted from the fingerprint. These features may include one or more of the following: a message is created based on the features of the fingerprint. For one embodiment, the message is a template including the features. For another embodiment, the message is a subset of features not included in a template. For another embodiment, the message is ghost points not corresponding to the features in the template. A message digest function is applied to the message to create a cryptographic key. Another embodiment of the present invention uses features of the fingerprint image to generate a digital certificate. The public key used for the digital certificate is based on a fingerprint image. In one embodiment, the digital certificate contains a template including the fingerprint image or the features extracted from the fingerprint image. Verification of this template provides additional security to the validity of the digital certificate.

Title: An information paging system with encryption function and its method
Inventor: FU WEN-JR
IPC: H04L9/00
Filed: 1998-11-24
Granted: 2001-08-21
Abstract: This invention introduces an information encryption method implemented in broadcast paging systems to prevent broadcasted data from improper interception. The method can be described as follows. First of all, the information to be transmitted is encoded. Then, authentication code and key code are set and combined with the original encoded data for encryption to generate encrypted data and complete verification code for broadcasting. By using paging receivers, users receive the broadcasted data. The complete verification code is examined and the encrypted data are decrypted based on the key code to generate the original encoded data. The encoded data are then decoded to restore to the original information for display.

Title: Apparatus for sputtering or arc evaporation
Inventor: WELTY RICHARD P
IPC: H01J25/50
Filed: 1999-02-12
Granted: 2000-09-11
Abstract: A linear magnetron cathode is disclosed which may be used as a vapor or plasma source for coating deposition or ion processing. The cathode has the shape of an elongated rectangular bar with vaporization of material occurring from an evaporable surface wrapping around the periphery of the bar, along two opposite sides and around both ends. A magnetic field is established over the entire evaporable surface which has a component parallel to the surface and perpendicular to the long direction of the cathode, forming a closed-loop magnetic tunnel around the periphery which directs an arc or sputtering plasma discharge. The cathode may be configured for either sputtering or cathodic arc evaporation by choice of magnetic field strength and lateral confinement means. The invention provides uniform cathode erosion and a vaporized material stream in two directions over an extended length, permitting uniform deposition or implantation over large areas. Substrate mounting and movement geometries are disclosed which allow efficient use of the bi-directional vapor emission distribution.

Abstract: A injection device is provided which comprises a cylinder section; a stationary plate fixed to a rear end of a cylinder section; a movable plate disposed such that it can be advanced and retracted relative to the stationary plate; an injection member disposed within the cylinder section such that it can be advanced and retracted and the rear end of the injection member is rotatably supported by the movable plate; a drive unit generating rotation when driven; plural conversion units disposed between the stationary plate and the movable plate and adapted to convert a rotational force to a thrust force; a transmission unit disposed between the drive unit and one of the conversion units and adapted to transmit a rotation generated by the drive unit to the conversion unit; and a synchronization unit provided in order to synchronize the rotation of the one of the conversion units with rotations of the remaining conversion units. In this case, rotation generated by the drive unit is transmitted via the transmission unit to one of the conversion units, and the rotation of the one conversion unit is synchronized with rotation of the remaining conversion units. Further, when the rotation is transmitted to each conversion unit, the rotational force is converted to thrust force and then transmitted to the injection member. At this time, the size of the driven pulleys can be reduced and so as the momentum.

Title: Device for vertically loading compact disk
Inventor: CHANG CHISHEN
IPC: G11B17/26
Filed: 1999-10-26
Granted: 2001-08-01
Abstract: A device for vertically loading compact disk is applied to a CD drive capable of being used vertically and horizontally. An elastic member, a first loading sheet, a second loading sheet are formed on one side of the tray of the CD drive which is a bottom when vertically arranged, so as to prevent the CD from turning over. A protrusion block on the loading mechanism base is employed together to drive the first loading sheet to enable the CD to normally rotate when the tray is turned back. As a result, the CD drive can be used for vertically loading and achieves the same effect as that for horizontally loading in the conventional skill.

Title: Page response on existing radio signaling channel
Inventor: WILLARS PER HANS AKE
IPC: H04M3/00
Filed: 1999-11-30
Granted: 2001-06-23
Abstract: When a mobile terminal in a mobile radio network has a user data connection established to a core network node, and receives a page message on a paging channel from a second core network node to which the terminal has no data connection established, the mobile terminal can send a page response message to the second core network node on the existing signaling channel between the mobile terminal and the radio access network associated with the established data connection to that core network node. The page response then triggers a multiplexing between the mobile terminal and radio access network, of the established connection with the first core network node and the desired call connection (precipitated by the page request) from the second core network node. This way, the mobile station can receive simultaneous calls from two different core network nodes over a common traffic and signaling connection.

Title: A pharmaceutical composition for increasing anti-CD38-immunotoxin cytotoxicity
Inventor: ROSENBLUM MICHAEL
IPC: A61K39/44
Filed: 2000-01-07
Granted: 2006-07-11
Abstract: The present invention is directed to the use of agents that induce high levels of cell surface molecules to provide targets for immunotoxins directed against the same cell surface molecules. A specific example is given in which all-trans-retinoic acid (RA) is used to induce high levels of CD38 cell surface antigen expression in several myeloid and lymphoid leukemia cells. CD38 was then used as target for delivering plant toxin (gelonin) to leukemia cells. Treatment of leukemia cells with RA induced high levels of CD38 in those cells that otherwise had low CD38 expression. The RA-induced leukemia cells then became exquisitely sensitive to an immunotoxin constructed from an anti-CD38 monoclonal antibody conjugated to the plant toxin gelonin.
