Inventor: ROSE INGO
IPC: A61C8/00
Filed: 1999-12-22
Abstract: In an implant driver assembly set comprising a dental implant and an insertion post, the insertion post has a cylindrical portion and an adjoining shoulder with which the driver assembly can be held in a constricted portion of a receptacle. A portion of the insertion post adjoining said shoulder in the direction of withdrawal provides frictional and/or interlocking engagement with an installation tool for withdrawing the implant driver assembly from the receptacle and for installing the implant at a site drilled in the jaw. The receptacle, preferably comprising a glass tube, is constricted radially about its circumference at the site of the holding means and closed at both end with sealing stoppers. The tool for withdrawing and screwing in the implant driver assembly comprises a tubular portion with a hex key socket at the open end of the inside wall and adjacent an inner tubular diameter that produces frictional engagement with the insertion post when they are brought into contact. The method for inserting the implant of the implant driver assembly is characterized in that after removal of the sealing stopper on the withdrawal side of the receptacle the tool is guided over the insertion post and made to engage frictionally with said post, that the driver assembly with the tool is then pulled out of the receptacle and screwed into the hole bored in the jaw, after which the screwed connection between the implant and the insertion post is released and the insertion post is pulled off.

Title: A method and apparatus for managing a firewall
Inventor: MAYER ALAIN JULES
IPC: H04L29/06
Filed: 2000-01-18
Abstract: A method and apparatus are disclosed for managing a firewall. The disclosed firewall manager facilitates the generation of a security policy for a particular network environment, and automatically generates the firewall-specific configuration files from the security policy simultaneously for multiple gateways. The security policy is separated from the vendor-specific rule syntax and semantics and from the actual network topology. Thus, the security administrator can focus on designing an appropriate policy without worrying about firewall rule complexity, rule ordering, and other low-level configuration issues. In addition, the administrator can maintain a consistent policy in the presence of intranet topology changes. The disclosed firewall manager utilizes a model definition language (MDL) and an associated parser to produce an entity relationship model. A model compiler translates the entityrelationship model into the appropriate firewall configuration files. The entity-relationship model provides a framework for representing both the firewall-independent security policy, and the network topology. The security policy is expressed in terms of "roles," which are used to define network capabilities of sending and receiving services. A role may be assumed by different hosts or host-groups in the network. A visualization and debugging tool is provided to transform the firewall-specific configuration files into a graphical representation of the current policy on the actual topology, allowing the viability of a chosen policy to be evaluated. A role-group may be closed to prevent the inheritance of roles.

IPC: H04L27/00
Filed: 2000-03-22
Abstract: A system and method for achieving carrier frequency synchronization in a high speed receiver. The system introduces a combination of down-sampling and extrapolation techniques that reduces the sampling rate in a carrier recovery sub-system to run the carrier recovery loop at a reduced rate. The total pipeline delay as seen by the carrier loop is thus reduced. This in turn allows for more efficient correction of residual carrier frequency errors present in the complex baseband signal.

Title: Ultrasonic seafood probe
Inventor: GUIGNE JACQUES Y
IPC: A22C29/02
Filed: 2000-06-07
Abstract: Apparatus for evaluating a part of a seafood animal such as a lobster claw, to determine the ratio of meat to water and other characteristics, including first and second transducers (12, 14) that are coupled to spaced locations on the part P  of the animal so when the first transducer transmits sonic energy it passes through the animal part to the second transducer. A circuit (34) coupled to the second transducer analyzes detected sonic energy. In one system, the circuit calculates the velocity of sound through the part of the seafood animal. A higher velocity indicates a higher meat content. Another circuit includes an indicator that indicates the amplitude of sound detected by the second transducer, especially the amplitude of sound of the predominant frequency generated by the first transducer, that has passed directly through the animal part. A lower amplitude indicates a higher meat content. A pressure sensor (124) automatically activates the first transducer to generate sonic energy, when the transducers are pressed with a predetermined force against the part of the seafood animal. The transducers can be mounted on a glove (92) between the thumb (T) and an opposed finger (F), so the part can be tested when it is picked up by a person wearing the glove.

Title: Amorphous diamond coating of blades
Inventor: DECKER THOMAS G
IPC: C23C14/06
Filed: 1995-04-21
Abstract: The invention provides improved razors, razor blades, and processes for producing razor blades or similar cutting tools with sharp and durable cutting edges. With this invention a hard carbon coating is applied to a blade having a cutting edge bounded by a first inclined surface and a second inclined surface, with an included blade angle enclosed by the inclined surfaces. An arc discharge is applied to an evaporable carbon surface of a cathode to generate a plasma stream of vaporized carbon in a generally directional stream resolvable into a set of roughly parallel lines. The blade to be coated is oriented within the plasma stream so that an angle measured from a line bisecting the included blade angle and one of the set of roughly parallel lines is with the range of 20° to 90°, so as to exposes one of the inclined surfaces to the plasma stream at that angle. The blade is presented to the plasma stream so that deposition of vaporized carbon occurs on both inclined surfaces of the blade cutting edge. The deposition takes place at an approximately equal rate of deposition on the two inclined surfaces. The coated blade is stiff and rigid while maintaining a high aspect ratio.

Abstract: An enhanced current sensing circuits, particularly suitable for use in telephony line interface cards is disclosed. The current sensing circuit includes a voltage sense circuit and sense amplifier that may be tuned for feed resistors of a given value to sense current through these feed resistors. Nominal values for the feed resistors are not required. A preferred voltage sense circuit includes a voltage dividing circuit connected across an impedance through which current is to be sensed. The voltage dividing circuit includes a tap to provide a voltage proportional to a voltage across the impedance, divided by a factor equal to a known multiple of the impedance. This sensed voltage may be determined without knowledge of the nominal value of the impedance and will be equal to a known fraction of the current through the impedance.        A similar second voltage dividing circuit may be used to sense voltage and hence current through a second impedance. The sensed voltages may be combined to form a signal indicative of the current attributable to a differential voltage across the two impedances. Conveniently, the current sensing circuit facilitates manufacture of telephony line interface cards in which resistors used to drive a subscriber loop may not need to be trimmed to a nominal value.
