  • Stabilization of resist material through ion implantation
    Publication number: 20030222345
    Abstract: A resist material used to mask an underlying layer during an etch process is subjected to ion implantation to harden the resist material against damage from the etch process. In a particular embodiment, the resist material is compatible with exposure to 193 nm radiation for patterning the resist material.

  • Measurement of airway calibre
    Patent number: 6074350
    Abstract: The variation in flow resistance of the respiratory system (Rrs) is determined as an indicator of variations in airway calibre, by oscillating the system, for example at 6 Hz for 5-15 minutes and determining the variations in ratio of the pressure difference (Prs) across the system that is in phase with flow, to flow V. The variation in airway calibre may be employed as a prognostic indicator in asthmatics and also to assess the efficacy of treatment.

  • Method for the enhancement of cell images
    Patent number: 5317644
    Abstract: The present invention relates to an image processing method for enhancing the digitised optical image section of a (e.g. substantially transparent biological) specimen and in a particular aspect the boundary outline of a specimen in such an image section thereof. In accordance with the invention a Nomarski image section is smoothed and a gradient of image pixel intensity determined for each pixel thereof. Thereafter each pixel of the smoothed Nomarski image which has an intensity gradient within a reference range is set to zero intensity so as to provide a processed image section.
