  • Inactivation of pathogens in ex vivo blood products in storage bags using visible light
    Patent number: 11951217
    Abstract: Disclosed herein are methods and devices for the inactivation of pathogens (e.g., bacteria, viruses, etc.) in ex vivo stored blood products, such as plasma and/or platelets, by means of directing visible light radiation from an illuminating device into blood product storage containers in order to achieve effective pathogen inactivation without the presence of an added photosensitising agent in the blood product. An exemplary apparatus includes a control unit that operates a light source that emits light in the wavelength region of about 380-500 nm which is directed onto blood product storage bags at sufficient intensity to penetrate the bag material and the opaque blood product therein in order to inactivate pathogens in the blood product but at dose levels that cause no significant detrimental effects on the blood product.

  • Optical fibre sensor interrogation system
    Patent number: 9310273
    Abstract: A monitoring system for monitoring a plurality of fiber Bragg gratings in an optical fiber, each fiber Bragg grating being sensitive to a different wavelength of light. The system comprises a broadband source for illuminating the optical fiber; at least one optical interferometer; light feeding means for feeding to an input of the interferometer light reflected from the fiber Bragg gratings, and a processor for processing the output from the interferometer to determine the wavelength of the reflected light. The light feeding means comprise a wavelength division multiplexer operable to separate light received from the optical fiber into a plurality of wavelengths, each associated with one of the fiber Bragg gratings and/or a time division mulitplexer operable to separate light received from the optical fiber into in a time separated series.

  • Quantum source coding apparatus and quantum information communication system
    Patent number: 7403713
    Abstract: Quantum source coding apparatus for communication of quantum information comprising: a quantum state preparation device for converting input messages into block messages; a coding device for producing coded signals by compressing the block messages prepared by the quantum state preparation device; and an output device for outputting the coded signals produced by the coding device.
