  • Patent number: 8398603
    Abstract: The present invention relates to a method and dressing for detecting detachment of the dressing, which is applied to a surface of an at least partly electrically conductive object. The dressing comprises an adhesive for attaching the dressing to the electrically conductive object and at least two electrodes arranged in a distance from the electrically conductive object. A voltage is applied to the first and second electrode establishing an electrical circuit comprising a first capacitor between the first electrode and the electrically conductive object and a second capacitor between the second electrode and the electrically conductive object. Changes of the capacitance between at least one of the first and the second electrode and the electrically conductive object are detected, and an alarm is activated when the changes of the capacitance reach a predetermined value. This advantageously provides a method whereby a leak can be detected quickly.

  • Patent number: 8084138
    Abstract: A method of decreasing the penetration depth of radiation provided to an interface, such as a surface, or a predetermined volume in a polyethylene (PE) element, where the PE element has a scattering coefficient larger than one tenth of an absorption coefficient thereof so that the radiation not absorbed at the interface or in the volume but transmitted further into the PE element is at least partly reflected toward the interface/volume. The radiation intensity is higher in the volume and the absorption coefficient may be reduced while retaining the total absorption in the volume.

  • Publication number: 20050018194
    Abstract: The invention relates to a surface plasmon resonance sensor comprising a base unit (2) containing a light source (6) for generating light beams (10) and an optical sensor unit (3; 21; 31; 103; 131) for exciting surface plasmons, said sensor unit having a measuring surface (18; 29; 122; 138) that is formed by a thin metal film and that can be brought into contact with a sample (19; 123) to be measured. The aim of the invention is to provide a surface plasmon resonance sensor (1) comprising a compact optical sensor unit (3; 21; 31; 103; 131) that is easy to replace reproducible quality. This is achieved by an optical sensor unit (3; 21; 31; 103; 131) comprising a prism (12; 22; 32; 112; 132) consisting of an optically transparent material. Areas (16, 20; 23, 24; 33, 34; 118, 119; 133, 134) of said prism (12; 22; 32; 112; 132) are configured in such a way, that they focus the light beams (10?) emanating from the base unit (2) onto the measuring surface (18; 29; 122; 138).

  • Publication number: 20040114145
    Abstract: The present invention relates to a biosensor, comprising a transparent sensor chip, and a sensing area for interaction between provided electromagnetic radiation and a substance. The interaction between the provided electromagnetic radiation and the substance defines at least part of a response of the biosensor. The biosensor further comprises a dispersion compensating element for compensation of dispersion induced by other parts of the biosensor so that the response of the biosensor becomes essentially independent of the wavelength of the provided electromagnetic radiation interacting with the substance. The dispersion compensating element provides the compensation at least substantially independently of the effective refractive index of the substance within a predetermined effective refractive index range. The present invention further relates to a method of making the dispersion compensating elements an integrated part of the biosensor.

  • Patent number: 6738141
    Abstract: Surface plasmon resonance (SPR) sensors comprise a sensor chip constructed of laterally integrated arrays of planar sensor chip units and an optical transducer constructed of laterally integrated arrays of planar optical transducer units. The replaceable sensor chip is separated from the optical transducer by a gap and perpendicular optical interconnections are between the sensor chip and the optical transducer. The optical interconnections between the sensor chip and the optical transducer are based on collimated light beams incident perpendicularly to the interfaces. Uncritical alignment of the optical transducer and the sensor chip is provided. The direction of the light beams will not be changed when passing through the interfaces between the sensor chip, the gap and the optical transducer eliminating the need of disposing refractive index matching gels in the gap.

  • Patent number: 6646744
    Abstract: The present invention provides configurations and a method of formation of optical coupling elements for surface plasmon resonance sensors. In the method of the present invention, interference patterns between two overlapping monochromatic coherent light beams are created on a photosensitive film disposed on a master substrate. At least one of the light beams has an oblique angle of incidence onto the master substrate, and the focal points of the two overlapping light beams are positioned in order to reduce optical aberrations up to third order. After developing the photosensitive film, the surface relief patterns pattern created on the master substrate is replicated as diffractive optical element onto SPR sensor chips. The diffractive optical elements working as optical coupling elements diffract an incoming light beam into an oblique angle within the range from 40 to ˜80 degrees.
