  • Patent number: 9035268
    Abstract: A system for measuring radiation dose comprises an excitation device adapted for directing an energy wave at a volume of a substance comprising gas-filled microparticles, a detector for detecting a response signal emitted and/or modified from the volume of the substance comprising gas-filled microparticles; and a control unit. The control unit is adapted for calculating a dose of ionizing radiation previously received by the volume of the substance based on the response signal. A method includes measuring a received dose of ionizing radiation and using a contrast agent for non-invasive in-situ dosimetry.

  • Patent number: 8963565
    Abstract: Present invention concerns generally to a sensor or a sensor system for detecting spilling of aqueous liquids, for instance in confined spaces were such is critical such in an airplane. The system of present invention is an early warning system or sentinel for the prevention of corrosion by corrosive liquids. Corrosion caused by corrosive liquids can rapidly change the surface properties of components in engineering structures, and that will finally endanger the functionality of structural parts. However, if monitoring technologies are in place providing continuous information on the presence of corrosive liquids, corrosion treatment and even corrosion prevention can start at a very early stage. Present invention provides such by early detection of corrosive liquids by extended sensors based on the collapse of percolation conductivity (COPC).

  • Publication number: 20130211633
    Abstract: The present invention relates generally to a system that monitors the condition of hydraulic systems for an aircraft or for other applications and, more particularly, to a system and method for detecting leakage within the hydraulic system aboard an aircraft. Such system is detecting hydraulic liquids by extended sensors based on the collapse of percolation conductivity (COPC) which sensors are covering an area in the aircraft.
