Abstract: Il s'agit d'une méthode et d'un dispositif de protection contre les chocs acoustiques. On fait appel à une approche fondée sur l'analyse de diagrammes du signal d'entrée pour effectuer l'extraction des caractéristiques. On détermine un espace paramétrique qui correspond à l'espace de signal du signal d'entrée. On applique une approche de décision à base de règles à l'espace paramétrique pour détecter un événement de choc acoustique. Le dispositif peut être mis en oeuvre de manière avantageuse en faisant appel à une approche d'addition à chevauchement pondéré pour obtenir un faible retard de groupe, une haute fidélité et un degré de protection élevé face aux événements de chocs acoustiques.

Abstract: Method and apparatus for non-invasively determining the time onset (Tonset) and end (Tend) of patient inspiratory efforts. A composite pressure signal is generated comprising the sum of an airway pressure signal, a gas flow pressure signal obtained by applying a gain factor (Kf) to a signal representing gas flow rate and a gas volume pressure signal obtained by applying a gain factor (Kv) to a signal representing volume of gas flow. Kf </sb> and Kv values are adjusted to result in a desired linear trajectory of composite pressure signal baseline in the latter part of the exhalation phase. The current composite pressure signal is compared with (i) selected earlier composite pressure signal values and/or (ii) value expected at current time based on extrapolation of composite pressure signal trajectory at specified earlier times and/or (iii) the current rate of change in the composite pressure signal with a selected earlier rates of change. The differences obtained by the comparison are compared with selected threshold values. T<sb>onset is identified when at least one of the differences exceeds the threshold values.

Abstract: A method for sharpening the comers of digital image data within an anti-aliasing image path so as to overcome corner rounding when displayed or printed.  The method comprises stepping a window across the image data and comparing that windowed data to templates or performing Boolean logic and arithmetic operations on the image data. Upon determining a match or a corner detection, pixel values are substituted in the identified pixel locations to achieve a clustering of the substituted pixel values about the corner structure producing a corner-enhanced digital image.  Filtering and sampling are then performed according to an anti-alias operation to the corner-enhanced image to produce an anti-aliased corner enhanced image. The data substitution will achieve a localized clustering or "ear" of toner/ink, or in the alternative for inside comers the localized clustered absence of toner/ink.  The result of this clustering is a sharpening of the corners so that they display or print as intended by the bitmap.
