Abstract: L'invention concerne un procédé pour optimiser le spectre de fréquence des impulsions émises par des sources à implosion par atténuation du pic de déclenchement P1 ou précurseur précédant le pic principal P2 dû à l'implosion. On utilise une pluralité de sources immergées à des profondeurs différentes et, par un déclenchement successif des sources suivant une séquence bien déterminée, on met en phase tous leurs pics d'implosion, tout en atténuant dans une très large mesure la résultante des différents pics de déclenchement, ce qui accroît la puissance acoustique émise et rend le spectre de fréquence plus homogène. Application à la prospection sismique marine.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of reconstructing original images from synthetic aperture radar image data, wherein in order to speed up the reconstruction of an original image from image data provided by synthetic aperture radar (SAR), the process for generating a point image pattern in correspondence to each point on the original image and the fast Fourier transformation (FFT) process for the generated point image pattern and 1-line image data are carried out once for every certain number of lines.          Positional and phase displacements created on a recon-structed image are corrected by multiplying a phase rotation factor to the product of the FFT-processed point image pattern and 1-line image data.

Abstract: ABSTRACT       A photoelectric touch input panel has a plurality of crossed light beams which are broken by an object, the position coordinates of which are identified as outputs.          Two spaced apart beam surfaces are provided, and the inter-relationship between the beams in the two planes is em-ployed to distinguish between interrupting objects on the basis of their size, attitude, and velocity characteris-tics.  The number of beams broken in any beam plane is counted to determined the relative size of the object, or to determine the center line of the interrupting object.          The beams in any beam plane are selected in accordance with the relative significance of the various beams, and interrupted beams are pulsed more rapidly than non-interrupted beams.  The light-emitting devices of the various beam planes are constructed as an integral unit.          The control system of the touch input panel is adapted for use in monitoring the size, shape, and activity of objects within a space defined by plural beam planes, independently of the touch input panel.

Abstract: Improved Filter for Data Processing Abstract An imaging method and apparatus having a new and improved data filter.  In one application of the inven-tion computed tomography number inaccuracies are avoided by use of a new filter function derived from discrete points of a truncated spatial domain convolution filter.          The points from the truncated convolution filter are fourier transformed to yield a ramp filter with ripple in the spatial frequency domain.  Data from a CT scan is filtered with this new filter function and back projected to produce images that do not exhibit CT number inaccuracies.

Abstract: ABSTRACT A particulate trap system used with a diesel engine has an exhaust conduit ducting exhaust materials through an exhaust cooler, then through a particulate trap, and then to the atmosphere.  A by-pass conduit is connected in parallel with the exhaust cooler, and valves are located in the exhaust conduit and the by-pass conduit.  A microprocessor-based control unit is arranged to allow normal operation with the exhaust materials passing through the cooler.  However, when backpressure in the exhaust conduit reaches a predetermined level due to particulate build-up in the. trap, the valves are gradually reversed, so that non-cooled exhaust materials arrive at the trap, thus regenerating it due to combustion.
