  • Publication number: 20120135374
    Abstract: There are disclosed apparatus and method for obtaining a proper emergence profile for a dental implant. An emergence profile guide may be seated into an osteotomy and a dental bur may be guided onto and along the emergence profile guide. The emergence profile guide may include a pilot, and the dental bur may include a corresponding channel, such that the channel rides onto the pilot. The dental bur is stopped by the emergence profile guide, such that a countersink is created with an optimum depth.

  • Publication number: 20110123950
    Abstract: A positioning device is used to place an implant in the proper vertical position within the soft tissue and bone, provide space for subsequent procedures, and create a proper emergence profile for the final restoration. The lower portion of the positioning device has substantially the same outer shape as that of the implant but without external screw threads or other mechanical features for anchoring the implant in the jawbone. After the hole is countersunk, the depth of the hole in the jawbone is increased incrementally and checked with the positioning device for collar engagement and location of the margin within the gum tissue and bone. After the proper vertical position is attained, a special countersink bur may be used to create needed space around the implant margin and provide a proper crown emergence profile.

  • Publication number: 20070271379
    Abstract: A privacy service is provided for use in protection of user data transferred in a network, including a converged network. The privacy service extracts and measures service elements of a message containing user data. The service elements include an identity element, a trust element, a rights element and a security element. The privacy service performs security by comparing service elements with a user defined privacy policy. The privacy policy may also be based on particular factors relating to the application, context, and time of the message. In another embodiment, the privacy service provides controls that indicate when user data is misappropriated as a result of an infringement of the user defined privacy policy. Further the privacy service provides a means to audit and trace deviations from the privacy policy for the purpose of repudiation, or future defense of security threats.

  • Publication number: 20070136821
    Abstract: A method and system for protecting data stored in a node are disclosed. Upon detection of an attempt to compromise security at a residing node, the data may be moved from the residing node to an escrow node which is a trustworthy intermediary node. The data may be encrypted prior to transmission to the escrow node. Stakeholders of the data may be notified of such movement so that the stakeholders may take action. An attempted breach of security may automatically place the residing node in a compromised state, upon which the owner may submit the residing node to a security bureau to clear the compromised state. The escrow node may transfer the data to an off-site node if the owner or user of the residing node is not trustworthy. The residing node may send a message to an intermediary node as a notification regarding a breach in security, and encrypts the data with a new encryption key issued by the intermediary node.

  • Publication number: 20070036353
    Abstract: The present invention relates to secret key generation and authentication methods that are based on joint randomness not shared by others (JRNSO), in which unique channel response between two communication terminals generates a secret key. Multiple network access points use a unique physical location of a receiving station to increase user data security. High data rate communication data is encrypted by generating a random key and a pseudo-random bit stream. A configurable interleaving is achieved by introduction of JRNSO bits to an encoder used for error-correction codes. Databases of user data are also protected by JRNSO-based key mechanisms. Additional random qualities are induced on the joint channel using MIMO eigen-beamforming, antenna array deflection, polarization selection, pattern deformation, and path selection by beamforming or time correlation. Gesturing induces randomness according to uniquely random patterns of a human user's arm movements inflected to the user device.

  • Publication number: 20060265333
    Abstract: A wireless mesh network with digital rights management (DRM) interoperability is disclosed. A first DRM-capable mesh point (MP) performs a discovery procedure for detecting neighbor MPs and identifies at least one other DRM-capable MP among the detected neighbor MPs. The first DRM-capable MP then performs an association procedure only with the DRM-capable MPs. The first DRM-capable MP assigns DRM roles to the associated DRM-capable MPs. A digital content is then distributed from the first DRM-capable MP to another DRM-capable MP via the mesh network. The DRM interoperability may be based on a networked environment for media orchestration (NEMO) architecture proposed by the Coral Consortium or any DRM interoperability architectures.

  • Publication number: 20060258355
    Abstract: A method and system for integrating media independent handover (MIH) under IEEE 802.21 and unlicensed mobile access (UMA) are disclosed. A public land mobile network (PLMN) and an unlicensed mobile access network (UMAN) are concurrently deployed. UMA is supported such that a multi-mode wireless transmit/receive unit (WTRU) may access the UMAN to receive PLMN services through the UMAN. MIH entities are included both in the VVTRU and the UMAN and the MIH entity of the WTRU monitors handover events and information and generates a handover trigger for handover between the PLMN and the UMAN. The MIH entity in the UMAN interacts with the MIH entity of the WTRU to report a remote event, handover information and command.

  • Publication number: 20060251020
    Abstract: A method and system for conveying media independent handover (MIH) capability information are disclosed. A wireless communication system includes a plurality of wireless networks deployed under different wireless communication protocols. A multi-mode wireless transmit/receive unit (WTRU) may perform a handover from one wireless network to another for continuous reception of services. The wireless network sends a message to the WTRU which indicates whether the wireless network supports MIH services and a supported MIH mode. The WTRU receives the message and makes a handover decision based on the message.

  • Publication number: 20060246904
    Abstract: A method for generating a media independent handover (MIH) trigger in a wireless local area network begins by sending a measurement report request message to a measurement entity in the network. The measurement entity takes the measurements and sends a measurement report response message to a medium access control (MAC) function. The MAC function evaluates the measurements and determines whether a handover condition exists, based on the measurements. The MAC function generates a MIH trigger if the handover condition exists.

  • Publication number: 20060227745
    Abstract: The present invention is a method and system for station location based neighbor determination and handover probability estimation. A serving access point determines the location and movement measurements of a station (STA). Neighboring access points report coordinates of cell fringes of the neighboring access points. The STA sends a request for system information to the current access point along with current location of the STA. The current access point provides the system information, and the STA utilizes the system information to determine best handover candidate from among neighboring access points and an estimate of the time for handover.

  • Publication number: 20060159047
    Abstract: A method and apparatus for triggering procedures to handover an ongoing communication session between a mobile station (MS) and a correspondent node (CoN) from via a first network of a first type to via a second network of a different type. Communication session continuity is maintained by transferring communication session context information when a handover is imminent from a network component in a first network path to a network component in a second network path, and by forwarding downlink and uplink signals via the network components in both the first and second network paths until the ongoing communication session can be established via the second network path. The context information includes the session communication parameters, such that the second network path can allocate resources and establish routing between the MS and the CoN.
