A wide area network using the internet as a backbone utilizing specially selected ISX / ISP providers whose routers route AlterWAN packets of said wide area network along private tunnels through the internet comprised of high bandwidth, low hop-count data paths. Firewalls are provided at each end of each private tunnel which recognize IP packets addressed to devices at the other end of the tunnel and encapsulate these packets in other IP packets which have a header which includes as the destination address, the IP address of the untrusted side of the firewall at the other end of the tunnel. The payload sections of these packets are the original IP packets and are encrypted and decrypted at both ends of the private tunnel using the same encryption algorithm using the same key or keys.

The invention concerns a method for producing three-dimensional objects (6) layer by layer using a powdery material which can be solidified by irradiating it with a beam (4) of charged particles, which method comprises the following steps: successive application of powder layers to a working area (5), and fusing together successive layers of said three-dimensional object (6) by successively irradiating the powdery layers with said beam (4). The invention is characterized in that it comprises the following steps: determining whether lifting of powdery material from the working area (5) occurs using a powder-lifting detection device (10, 10a, 10b, 10c, 1Od, 1Oe) capable of generating a signal (S) upon detection of lifting of powdery material from the working area (5), and interrupting the irradiation of at least a part of the working area (5) where powder lifting occurs using the signal (S) generated by the powder-lifting detection device (10, 10a, 10b, 10c, 10d, 1Oe) for automatically trigging the interruption. The invention also concerns an apparatus (1) for producing three-dimensional objects (6) layer by layer using a powdery material which can be solidified by irradiating it with a beam (4) of charged particles, said apparatus (1) comprising means for successive application of powder layers to a work table, and a radiation gun (3) for delivering said beam (4) of charged particles, wherein the inventive apparatus (1) comprises a powder-lifting detection device (10, 10a, 10b, 10c, 10d, 10e) capable of generating a signal (S) upon detection of lifting of powdery material from the working area (5).

A method for forming a stamper used in the manufacture of CDs, DVDs, and other types of optical disks comprises forming a substrate by rolling. A layer of material is deposited (e.g. by plating) onto the substrate. Thereafter, a resist layer is formed on the layer of material and patterned. Because the substrate is formed by rolling, it is relatively inexpensive to form the substrate to a desired thickness. Because the layer of material is formed by deposition (e.g. plating), it is relatively inexpensive to ensure that the layer has a very smooth surface (i.e. without necessitating a great deal of polishing).

A method is provided for a virtual clinic to establish communications between a user (e.g., a patient) and a specialist (e.g., a physician) in order to facilitate a diagnosis. In various embodiments, a user provides a request for the specialist to a virtual clinic. The request may be a request for medical services identifying medical needs. The user may then receive specialist information from the virtual clinic. The virtual clinic may establish real-time communication between the user and a specialist. The user may receive instructions from the specialist via the virtual clinic to perform a test. The user may then report a test result from the test to the specialist via the virtual clinic. The virtual clinic may receive and store a diagnosis from the specialist.

The invention relates to a method of determining an identifier of determined discriminating power from biometric data. According to the method, biometric data is obtained relating to an individual. The biometric data is converted into a digital string. A word of an error-correcting code is associated with the individual. The error-correcting code word is added to the digital string. An identifier relating to the individual is determined by applying a hashing function to the error-correcting code word, the hashing function being selected to ensure the determined discriminating power to said identifier.
