An ostomy appliance includes a first adhesive having a first surface and a second surface opposing the first surface. The first surface is provided to contact a partly electrically conductive object. The appliance also includes a first layer situated on the second surface of the first adhesive, and a first electrode situated on the first layer and electrically isolated from the first adhesive.

Ostomy appliance having an electrode

A method of detecting detachment of an ostomy device from a patient includes providing, in the ostomy device, a first electrode separated from the patient by an adhesive that attaches the ostomy device to the patient, where a first capacitor is formed between the first electrode and the patient. The method includes applying a signal to an electrical circuit that includes the first capacitor, and detecting changes in a capacitance value of the first capacitor based on frequency responses of the electrical circuit to the signal. The method additionally includes activating an alarm based upon detecting the changes in the capacitance value of the first capacitor.

A dressing is provided for application to an object that is, at least partly, electrically conductive. The dressing includes an adhesive for attaching the dressing to the object, and at least two electrodes. The electrodes are adapted to be arranged at a distance from the partly electrically conductive object so that a first capacitor is formed between a first electrode and the partly electrically conductive object, and a second capacitor is formed between a second electrode and the partly electrically conductive object.

Leak sensor

A method of laser welding a layered product comprising two layers () of a high absorption at the radiation wavelength, where one layer () is welded to a material () having a lower absorption and wherein a scattering layer () is provided between the laser welded layers () and the other high absorption layer () in order to scatter any radiation penetrating the first high absorption layer () in order to prevent excessive heating of the other high absorption layer ().

Method of providing a laser welded product and a laser welded product

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. Furthermore, this advantageously provides a leak sensor with no direct physical or mechanical contact between the electrically conductive object, e.g. the skin, and the electrodes. This provides for a dressing comprising a leak sensor without compromising the comfort of the user.

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.

Polyethylene product and a method of providing a product, such as a laser welded polyethylene product

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.

Surface plasmon resonance sensor

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 &tilde;80 degrees.
