  • System for detecting the presence of moisture
    Patent number: 6832507
    Abstract: The system comprises at least one electronic sensor for detecting the presence of moisture. The system further comprises at least one reading device for obtaining information from the sensor about the presence of moisture. The sensor comprises a resonant circuit which is at least partly formed from a moisture sensitive material, the electrical resistance of which increases when the material comes into contact with moisture. The reading device comprises transmitter-receiver means for generating an elecromagnetic interrogation field.

  • Moisture sensor, diaper with such a sensor, and method for detecting the presence and/or the intactness of the moisture sensor
    Publication number: 20040095247
    Abstract: The moisture sensor for detecting moisture comprises at least one first electrode provided with at least one IGP, at least one second electrode and a dielectric included between the first and the second electrode. The dielectric is of a type that can absorb moisture, so that the presence of moisture can be detected on the basis of an electric voltage difference between the first and the second electrode. The first electrode is provided with a ribbon-shaped carrier, to which the at least one IGP is applied.

  • Sensor for detecting the presence of moisture
    Publication number: 20040089058
    Abstract: The invention relates to a sensor for detecting the presence of moisture. The sensor comprise an electric circuit and IPs. Electric properties of the ICPs are dependent on the amount of moisture with which the come into contact. The electric circuit is arranged for detecting a change of the electric properties of the ICPs for detecting moisture. The ICPs form part of a capacity, the electric circuit being arranged for detecting a change of the capacity for detecting moisture.

  • Method for applying a coating to a substrate
    Patent number: 6649224
    Abstract: A method of applying a coating to a surface of a substrate, comprising the steps of: introducing a substrate into an atmosphere which consists of at least one chemically reactive compound, water and at least one of nitrogen and argon, and thereafter using a corona discharge on the surface of the substrate to form a coating from the reactive compound having an inhibiting effect on the permeability to vapor and/or gas.
