Abstract: In a method for providing a welded construction generated in an at least partially computer-assisted manner, especially for industrial transmission, an individual construction-specific input parameter of at least part of the welded structure is defined manually and/or with computer assistance from build size parameter, terminal fit parameter, and build shape parameter. A database includes a partly variable construction kit in which at least two standardized parts are recorded, with one of the at least two standardized parts being selected in a computer-assisted manner to form the welded construction. The welded construction is generated in a computer-assisted manner using the selected one of the at least two standardized parts and taking into account of the individual construction-specific input parameter.

Abstract: The invention relates to an inductive charging device having at least one inductive charging coil wound about a coil axis, and an electric or dielectric antenna, which is arranged at a location that is shifted parallel to the coil axis in relation to a location of a region of the charging coil, a location within the at least one charging coil, or a location between the charging coils. The electric vehicle and the charging station each have such an inductive charging device. With the method, one or two such inductive charging devices are used, wherein by means of the inductive charging coils, energy is transmitted, and by means of the antennas, communications data are transmitted.

Abstract: This invention shows a method for operating a voice communications network that comprises dynamically associating a private number with at least one public number of a circuit-switched voice communication network, authenticating a user of a private number without reliance on a static reproducible data code, receiving an incoming call to the public number and routing the incoming call from a caller to the private number. The method also shows the generation of an outgoing call from the private number and passing the outgoing call through the public number while generating calling party information to a target which preserves the privacy of the caller, and altering an associating of the private number and at least one public number. The system therefore acts as a proxy with authentication by means of dynamic code security. The caller and the user of the private number share seamless round-trip telephone communications while preserving the anonymity of the user of the private number.

Abstract: A system and method for authenticating documents and content thereof. A counterfeit resistant document recording medium is provided, having thereon a predefined unique document identifier and at least one security feature. The recording medium is thereafter imprinted with document content, which typically varies between documents. The document content is stored in a database, indexed by an associated document identifier. The document may then be authenticated by checking the security feature and comparing the stored document content with a perceived document content. The system provides a number of opportunities for commercial exploitation, including sales of identified recording media, recording of information in a database, on-line authentication transactions, differential accounting for document validations and counterfeit identifications, imprinting devices, authentication devices, and the like.

Abstract: A system including a storage medium containing encrypted information comprises: (a) a control unit for selecting information to be retrieved from the storage medium; (b) a storage medium reader for reading the selected information from the storage medium; and (c) a decryption device for decrypting at least portions of the selected information using a decryption key. The decryption key is defined, at least in part, by rules and/or data which are read from the storage medium by the storage medium reader. A different and unique key is associated with each separate item or file of encrypted information.

Abstract: A device is disclosed for retrieving information from a secure electronic information source, wherein at least some of the information is in encrypted form and may be decrypted for use. The device comprises:(a) a computer, having an input device and a display device, for selecting information to be retrieved from the information source;(b) an information retrieval device, coupled to the computer, for retrieving the selected information from the information source;(c) a decryption device, coupled to the computer, for decrypting at least portions of the selected information retrieved from the information source; and(d) a data logging device, coupled to the computer, for maintaining a data log of the selected information as it is retrieved from said information source and decrypted. According to the invention, a unique brand code is automatically, electronically added to at least some of the selected and decrypted information, and to the data log.

Abstract: A personal computer or "host computer" and a Mass storage device are arranged on an SCSI bus. A "decryption controller", in a separate enclosure outside of the host computer, is also arranged on the SCSI bus. This controller is addressable by the host computer as if it were the mass storage device. Upon receipt of an information request, the decryption controller initiates a request to the mass storage device for the desired information, retrieves this information, decrypts it (if it is encrypted) and then passes it to the host computer. The decryption controller is thus "transparent" to the host computer.

Abstract: A luminaire includes a lenticular lens. Each lentical comprises a convex lens having a highly polished aspheric curved surface. The aspheric surface is divided into a plurality of coaxial zones, each designed to accept a specific quantity of parallel light flux from a parabolic reflector positioned within the luminaire and then refract that quantity of flux into a specific solid angle of the projected beam. The convergence of light rays by each lens element produces a real image of the light source in front of the lenticular lens. Each lentical produces a separate image and all images were substantially identical.
