  • Patent number: 8184972
    Abstract: Data is encrypted onto an electromagnetic beam by providing an electromagnetic beam having a signal component having a modal state, wherein the signal component is susceptible to accumulation of a geometric phase, and a reference component, transmitted along a path over at least part of which the signal component accumulates a geometric phase by transformation of its modal state from a first to a second modal state, from the second to at least one further modal state, and then back to the first modal state; and modulating with the data the geometric phase so accumulated, by modulating the modal state transformations. Data is decrypted from a received electromagnetic beam by corresponding processing of the received electromagnetic beam and by comparing an overall phase of the signal component with an overall phase of the reference component so as to retrieve the modulation.

  • Publication number: 20110191933
    Abstract: An attachment system principally use on garment (10, 30) provides a number of aligned loops (15) on the garment and a number of aligned loops (24) on a load such as an equipment pack (17). The load also includes an elongate securing member that extends from the load with a flexible proximal portion (26) and a stiffened distal portion (27). The stiffened distal portion (27) can be very readily threaded through successive ensemble loops (15) and load loops (24) to pull the flexible proximal portion (26) through the loops (15, 24) to attach the load (17) to the garment (10, 30). The stiffened distal portion (27) is then fed back through the loops (15, 24) to provide a geometric lock that prevents the load (17, 18) detaching from the garment (10, 30). Various loads can be attached in this way.

  • Patent number: 7110649
    Abstract: A fresenel zoned microstructured optical fiber is described. The fiber is constructed of concentric zones, each zone being defined by discontinuities in the refractive index. The refractive index within each zone may either be constant or may vary, for example each zone being a section of a parabola or hyperbola. The fiber may be used as a lens, for example for coupling light between fibers with different core sizes.

  • Patent number: 6544392
    Abstract: There is disclosed an improved apparatus for manufacturing printed circuit boards which solves the problem of immersion bath contaminants being plated-out onto electrically-conductive, circuit functional pads, (board-features) by introducing into the bath system a mechanism for attracting those contaminants to non-functional “micro-thieves” which are electrically-conductive, non-circuit-functional pads having substantially smaller dimensions than those of the smallest board-feature, thereby taking advantage of previously unknown immersion bath uncontrolled strike phenomena, whereby the contaminants are directed to the micro-thieves and away from the board-features. Application of the micro-thieves in the immersion bath environment also produces plated features, of both finer and larger geometries, having flatter surfaces and a more uniform plated thickness for all features on the printed circuit board (PCB), than previously obtained.

  • Publication number: 20020116454
    Abstract: A system for and method of facilitating data communication between (i) a first computer system that runs a legacy application and is operable as a service provider and (ii) a second computer system that is operable as a requester. Multi-layered software adapters are respectively interposed between an electronic network and each of the first and second computers thereby connecting the first and second computers to each other via the adapters. The first computer, which is operable as a service provider and runs the legacy application, publishes an interface model of its legacy application functions. The second computer, which is operable as a requester, looks up, via its adapter, the published interface model when a request for data that is available from the legacy application is made by the second computer. The adapters then communicate with each other in a common format and protocol to exchange information and data as is desired.
