Title: An improved method for network address translation
Inventor: TZENG HONG-YI
IPC: H04L29/12
Filed: 1999-01-26
Granted: 2002-11-26
Abstract: A method for translating non Internet unique addresses of a home network device to an Internet unique address for internet communication through a router. Every device within a given home network is assigned three addresses:(i) a configured address identical to the network address of the router enabling access to an Internet; (ii) a logical address visible only to the other devices in the same home network; and (iii) a medium access control ("MAC") address. Every packet originating from a home network source device includes its MAC address, the router MAC address, its configured address and the network destination address, and is forwarded to its destination through the router. The router examines the network destination address to determine whether the communication is intranet or internet. For intranet communications the router replaces the configured address of the home network source device with the logical address of the home network source device, the logical address of the home network destination device with the configured address, its MAC  address with the MAC address of the home network destination device, and forwards the packet to the home network destination device. For Internet communications the router forwards the packet along the Internet without replacing any of the source or destination information in the headers of the packet. Based on the source MAC address, however, the router records the logical address of the home network source device as well as the DA, SP, DP and PT in order to identify a response to the packet from the Internet destination device.

Abstract: Cette invention concerne un procédé de fabrication d'une banque d'ADNc qui correspond à l'ARNm dans toute sa longueur. Ce procédé consiste à former des complexes ARN-ADN en effectuant la transcription inverse de primères qui utilisent l'ARNm comme modèle. Une molécule jouant le rôle d'étiquette est ensuite liée chimiquement à la structure diol située dans le site 5'Cap (<7Me>GpppN) de l'ARNm constituant les complexes ARN-ADN. Le complexe ARN-ADN, qui possède un ADN correspondant à un ARNm dans toute sa longueur, est ensuite séparé des complexes ARN-ADN auxquels est liée la molécule étiquette en tirant avantage de la fonction de cette dernière. Ce procédé permet ainsi de former une banque d'ADNc dans toute sa longueur en étiquetant efficacement le site 5'Cap par une réaction protéine/enzyme. Il est ainsi possible d'éliminer tout manque d'efficacité dû à un clivage de l'ARNm lors de la synthèse d'ADNc dans toute sa longueur, et de synthétiser ce dernier avec une grande efficacité.

Title: Mid row banding coulter drill
Inventor: BOURGAULT GERARD F J
IPC: A01C7/06
Filed: 1999-06-07
Granted: 2002-12-10
Abstract: Disclosed is a novel coulter closing wheel assembly and a method of planting crops. Also disclosed is a mid row banding pneumatic coulter drill used to support the unique coulter assemblies. The seed coulters and fertilizer coulters are positioned such that in the direction of the travel one fertilizer coulter is positioned between two seeding coulters.      The seeding coulters are always followed by a furrow closing wheel which in effect scrubs the ground and pushes soil back into the furrow. The seeding coulters are also followed directly by a press wheel or packer wheel. The fertilizer coulters may or may not employ a furrow closing wheel, depending on the type of fertilizer which is being placed in the soil and to a lesser degree depending on the type of soil.      In the event of granular or liquid nitrogen fertilizers the closer wheel is generally not necessary. However, when a gaseous fertilizer such as anhydrous ammonia is applied to the soil, the furrow closing wheel is necessary in order to prevent the escape of the anhydrous ammonia into the atmosphere. The coulters are firmly attached to horizontal frame members of the drill and placed at an angle of a few degrees off the direction of travel. The injection of fertilizer directly between a pair of seed rows ensures a steady supply of nitrogen or other fertilizers throughout the growing period. In addition, since the fertilizer is placed a fair distance from each of the seed rows, it will not scorch or burn the roots of the growing crop.

Title: Atmospheric-pressure plasma jet
Inventor: SELWYN GARY S
IPC: H05H1/24
Filed: 1998-01-23
Granted: 2006-02-14
Abstract: A .gamma.-mode, resonant-cavity plasma discharge (18) that can be operated a t atmospheric pressure and near room temperature using 13.56 MHz rf power is described. Unlike plasma torches, the discharge produc es a gas-phase effluent no hotter than 250 .degree.C at an applied power of about 300 W, and shows distinct non-thermal characteristics. In the simplest design, two concentric cylindrical electrodes (14, 20) are employed to generate a plasma in the annular region therebetween. A "jet" of long-lived metastable and reactive species (22) that are capable of rapidly cleaning or etching metals and other materials is generated which extends up to 8 in, beyond the open end of the electrodes (14, 20). Arcing is prevented in the apparatus by using gas mixtures containing He, which limits ionization, by using high flow velocities, and by properly shaping the rf-powered electrode (14). Because o f the atmospheric pressure operation, no ions survive for a sufficiently long distance beyond the active plasma discharge to bombard a workpiece, unlike low-pressure plasma sources and conventional plasmas.

Granted: 2007-05-15
Abstract: The invention relates to a system by which external users (35, 36), such as subscribers and service providers, can update their service data in a secure and controlled manner on a self-service basis in an intelligent network or other telecommunications network. An access system (SMAP) separate from the actual telecommunications services managing network elements (CCB, HLR, SMP/SMS, SCP) is implemented in the invention, said access system providing the customers and service providers with an open interface to these network elements through a public data network. The access system (SMAP) controls access to the actual network elements by, for example, authenticating the party requesting access, checking whether the requesting party is associated with the data he/she desires to manipulate, and/or checking to which processing operations the requesting party is entitled. The users can thus access their own service data in the network elements managing the data in a manner controlled by the access system (SMAP).
