摘要:
The invention provides systems for integrated haptic design and fabrication of dental restorations that provide significant advantages over traditional practice and existing computer-based systems. The systems feature technical advances that result in significantly more streamlined, versatile, and efficient design and fabrication of dental restorations. Among these technical advances are the introduction of voxel-based models; the use of a combination of geometric representations such as voxels and NURBS representations; the automatic identification of an initial preparation (prep) line and an initial path of insertion; the ability of a user to intuitively, haptically adjust the initial prep line and/or the initial path of insertion; the automatic identification of occlusions and draft angle conflicts (e.g., undercuts); the haptic simulation and/or marking of occlusions and draft angle conflicts; and coordination between design output and rapid prototyping/milling and/or investment casting.

A system and method for performing authentication are disclosed. The system may include a shared central processing server, a plurality of software components each residing in a corresponding point-of-sale (POS) workstation and an identity provider service. The server may reside at a merchant location and communicate with multiple POS workstations at the merchant location. The server may be configured to receive biometric information from each POS workstation. Each software component may communicate with a biometric sensor in communication with the corresponding POS workstation to receive biometric information. The identity provider service may be configured to communicate with the server, store registered biometric information and compare biometric information received from the server with one or more of the stored registered biometric information. One of the biometric sensor, a POS workstation and the server may convert a biometric image into a biometric template for comparison with the stored registered biometric information.

The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.

A method for encoding XML tree data that includes the step of encoding the semi-structured data into strings of arbitrary length in a way that maintains non-structural and structural information about the XML data, and enables indexing the encoded XML data in a way that facilitates efficient search and browsing.

An improved system and method for publishing messages asynchronously in a distributed database is provided. Clusters of sequencer servers and broker servers may provide services for asynchronously publishing messages about topics including transactions for performing semantic operations on data in the distributed database system. A publisher client may send a message to a sequencer server that may add a sequence number to the message for the topic. The sequencer server may send the message to a primary broker server and a secondary broker server for asynchronous publication to subscribers of the topic of the message. If the primary broker server fails, the message sent to the secondary broker may be distributed to subscribers of the topic of the message. A subscriber client may receive the message and may order the messages received by sequence number for consumption by an application such as a subscriber database engine.

A technique is described that reduces the complexity and resource consumption associated with performing record expiry in a distributed database system. In accordance with the technique, a record is checked to see if it has expired only when it has been accessed for a read or a write. If at the time of a read a record is determined to have expired, then it is not served. If at the time of a write a record is determined to have expired, then the write is treated as an insertion of a new record, and steps are taken to treat the insertion consistently with regard to the previous expired version. A background process is used to delete records that have not been written to or actively deleted by a client after expiration.
