Title: Virtual private networks and methods for their operation
Inventor: HURREN ALAN JAMES
IPC: H04L9/32
Filed: 2000-01-20
Granted: 2008-08-05
Abstract: In methods and apparatus for routing packets through a communications network, a respective distinct broadcast address is assigned to each of a plurality of distinct sets of virtual ports. No virtual port belongs to more than one of the distinct sets. A respective egress address is assigned to each packet entering the network via an ingress virtual port. The respective egress address corresponds to a respective destination address of the entering packet when a correspondence between the destination address and an egress address is known. When no correspondence between the destination address and an egress address is known, the respective egress address is a broadcast egress address corresponding to the set comprising the ingress virtual port. The packet is routed according to the respective egress address. The routing is restricted to virtual ports belonging to the distinct set of virtual ports that includes the ingress virtual port. The distinct sets of virtual ports and their associated broadcast addresses define isolated virtual private networks within the network. Each physical port of the network may map one-to-one onto a corresponding virtual port, or may map onto a corresponding plurality of virtual ports, in which case the each virtual port of the plurality is associated with a respective distinct combination of a physical address of the physical port and a respective virtual network identifier.

Title: Methods of synthesizing polynucleotides by ligation of multiple oligomers
Inventor: AKHAVAN-TAFTI HASHEM
IPC: C12P19/34
Filed: 1999-07-22
Granted: 2010-04-13
Abstract: Methods of synthesizing polynucleotides are disclosed involving the simultaneous ligation of a set of oligomer 5'-phosphates onto a template-bound primer. The set of these oligomers can be preselected to contain oligomers which are complementary to the template strand or the oligomers can be supplied as a library and allowed to self select. The synthesis by ligation can proceed unidirectionally or bidirectionally from the primer and can be used to synthesize both strands simultaneously by the use of two primers. The ligation is preferably performed with a ligase enzyme. The methods of synthesis are useful in a variety of applications, including cloning, amplification, labeling, diagnostic assays, mutation analysis and screening, gene expression monitoring and sequence analysis.

Abstract: Emballage dépliable (1) pour pop-corn préparé aux micro-ondes, qui contient une quantité de graines de maïs à éclater (14) destinées à être préparées dans un four à micro-ondes. L'emballage (1) est formé d'un panneau avant et d'un panneau arrière (2, 4), de préférence réunis à leurs extrémités supérieures et inférieures par un adhésif et sur les côtés par des panneaux latéraux (6, 8). Le panneau arrière (4) présente une paire de lignes de séparation (18) le long desquelles le matériau de l'emballage est relativement faible, de façon que l'on puisse déchirer et séparer une partie (16) dudit panneau du reste de l'emballage afin de découvrir le pop-corn contenu à l'intérieur. On peut former les lignes de séparation (18) en affaiblissant une partie du substrat du sac ou en renforçant les zones adjacentes, ou bien par combinaison des deux techniques. On replie les panneaux latéraux (6, 8) de façon à former des soufflets (7) qui permettent à l'emballage de rester plat durant le stockage, puis de se déplier afin de loger les graines de maïs. Un suscepteur (9), placé de préférence sur le panneau avant (2) à l'opposé du panneau arrière, améliore l'effet d'éclatement.

Abstract: An administrator contracts with an advertiser and a holder holding a right to let a third person use digital content. The holder sets the digital content to become usable by using an execution key, downloads the execution key to the administrator through a network, and downloads the digital content not made usable to a distributor through the network. The distributor downloads the digital content to a user through the network. When the user sends an execution declaration of the digital content to the administrator, the administrator downloads the execution key and an advertising information piece received from the advertiser to the user through the network. Therefore, the user can use the digital content made usable by the execution key while seeing the advertising information piece. Thereafter, the administrator collects an advertisement rate corresponding to the number of execution times of the digital content from the advertiser and pays an execution fee corresponding to the number of execution times of the digital content to the holder. Accordingly, the user can enjoy a desired digital content without charge, and the administrator is not required to collect the execution fee from each of many users.

Abstract: A premium "fuel-grade" petroleum coke is produced by modifying petroleum coking technology. Coking process parameters are controlled to consistently produce petroleum coke within a predeterminedrange for volatile combustible material (VCM) content. The invention includes a process of producing a coke fuel, the method comprising steps: (a) obtaining a coke precursor material derived fromcrude oil and having a volatile organic component; and (b) subjecting the coke precursor material to a thermal cracking process for sufficient time and at sufficient temperature and under sufficient pressure so as to produce a coke product having volatile combustible materials (VCMs) present in an amount in the range of from about 13 % to about 50 % by weight. Most preferably, the volatile combustible materials in the coke product typically may be inthe range of from about 15 % to about 30 % by weight. The present invention also provides methods for (1) altering the coke crystalline structure, (2) improving the quality of the coke VCM, and(3) reducing the concentration of coke contaminants. Fuels made from the inventive coke product and methods of producing energy through the combustion of such fuels are also included. Finally, novel environmental control techniques are developed to take optimal advantage of the unique characteristics of this upgraded petroleum coke.

Abstract: Devices and methods for performing intrvenous vascular procedures without cardiac bypass. The devices include various embodiments of temporary filter devices (10), temporary valves (26, 100), and prosthetic valves (80, 85, 86, 90). The temporary filter devices (10) have one or more cannulae (2) which provide access for surgical tools for effecting repair of the cardiac valves. A cannula (2) may have filters (3) of various configurations encircling the distal region of the cannula, which prevents embolism material from entering the coronary arteries, and aorta. In one embodiment, a set of valve leaflets (70, 71) extend peripherally from the filter to prevent blood flow through peripheral arteries. The temporary valve devices (26) may also have one or more cannulae (2') which guide insertion of the valve into the aorta. The valve devices (26) expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve (26) is a disc of flexible, porous material that acts to filter blood passing therethrough. In another embodiment, the temporary valve (100) has leaflets (111) which act in concert to alternately block or allow blood flow.
