  • SYSTEM FOR MONITORING RESPIRATORY EFFORT
    Publication number: 20170181663
    Abstract: System for monitoring respiratory effort in a patient, comprising at least one pressure sensor, the pressure sensor being positioned in a catheter and being adapted for positioning in a chosen position in the oesophagus, the pressure sensor being adapted to monitor the pressure difference between the oesophagus and external pressure at a chosen rate. The system comprises flow measuring means for measuring the respiratory flow and analyzing means for calculating the respiratory admittance or the respiratory impedance as well as detecting the respiratory related arousals.

  • Method of preparing an object for submerged sonar inspection
    Publication number: 20090250839
    Abstract: Objects which are to be inspected by sonar imaging when they are submerged are coated with or formed with a surface which is a non-specular sonar reflector.

  • Patch test for 3D sonar data
    Publication number: 20080198694
    Abstract: A method of automatically performing a patch test for a sonar system is disclosed, where data from a plurality of overlapping 3D sonar scans of a surface as the platform is moved are used to compensate for biases in mounting the sonar system on the platform.

  • Method of constructing mathematical representations of objects from reflected sonar signals
    Publication number: 20080043572
    Abstract: Data recorded by directing a single sonar beam pulse towards a surface, and recording the reflected sonar signals with a large plurality of detectors, is used to generate a mathematical representation of the surface. The mathematical representation of the surface is chosen to fit the recorded data according to a criterion such as a least squares fit of a plane to the recorded data points. A mathematical representation of on object is built up from a number of non-overlapping mathematical objects such as triangles, each triangle joined to adjoining triangles to form a continuous surface in three dimensions. Images of such mathematical representations are then presented to the observer.
