Title: Voile a ski
Inventor: POTVIN RAYMOND
IPC: B63H9/06
Filed: 1995-06-20
Abstract: Pour faire de la voile avec un cerf-volant, il faut qu'on puisse le diriger, qu'il soit près de soi et que l'on puisse agir directement sur sa structure, ou qu'il soit auto-stable et que l'on puisse agir sur sa direction aumoyen de cordes. Lorsqu'on se déplace sur le terrain, la principale difficulté est d'éviter que le cerf-volant ne touche la surface: dans ce cas, il pivote et s'effondre. S'il possède une structure rigide, elle risque de briser, s'il est mou comme un parapente, ses cordes s'emmêlent à cause de leur longueur et il faut du temps pour le réinstaller. Une autre caractéristique du cerf-volant parapente est qu'il faut une bonne technique pour l'utiliser et qu'il peut s'effondrer si le vent est turbulent. La présente invention concerne un cerf-volant de style parapente compact que l'on tient près de soi pour faire de la voile grâce à un support en " T " où s'attachent les cordes. A cause de sa forme compacte, ce cerfvolant ne s'effondre pas dans les turbulences et glisse au lieu de pivoter lorsqu'il touche la surface. Deux pièces de toile agissant comme queues sont rattachées au bout arrière du support en " T " et assurent la stabilité au parapente. Si on le manie mal, comme le cerf-volant est près de soi, on peut le réinstaller sans aide très rapidement.

Patent CA-2161048-A1 (CA)
Inventor: BANCROFT JOHN C
IPC: G01V1/36
Filed: 1995-10-20
Abstract: A method of prestack time migration based on the principles of prestack Kirchhoff time migration that can be applied to both 2-D and 3-D data.  Common scatter point (CSP) gathers are created as an intermediate step for each output migrated trace. Normal moveout (NMO) and stacking of CSP gathers is performed to complete the prestack migration process.  The method of the present invention allows the CSP gathers to be formed at any arbitrary location for velocity analysis, or to prestack migrate a 2-D line from a 3-D volume. The CSP gather is similar to a CMP gather as both contain offset traces, and both represent a vertical array of scatter points or reflectors.  The CSP gather is formed from all the input traces within the migration aperture.  Samples in the input traces are assigned an equivalent offset for each CSP location, then copied into the appropriate offset bin of the CSP gather in an efficient manner.  The input time samples remains at the same time when copied to the CSP gather.  Data in the CSP gathers may be scaled, filtered, or have noise attenuation processes applied.  The equivalent offset may be derived in a simplified form as a combination NMO and post-stack migration or in a more complex form based on the double square root (DSR) equation of prestack migration.  The prestack migration form of the CSP gather enables it to correctly image scattered and dipping events prior to NMO.  The prestack nature, high fold, and large offsets aid in providing a better focus of the semblance plot for an improved velocity analysis.

IPC: H04N19/503
Filed: 1996-09-17
Abstract: Data decoded by a decoding section (101) are compressed by a compressing section (102) and then stored in a forecast/display frame memory section (103).  The data in the forecast/display frame memory section (103) which are required to decode the other frames in the decoding section (101) are expanded and supplied to the decoding section through an expanding A section (104).  The decoding section (101) uses the data restored by the expanding operation to decode the image data subjected to the forecast encoding operation.  On the other hand, the display frame is subjected to the expanding operation at an expanding B section (105) after it has been read out from the forecast/display frame memory section (103), the expanded display frame then being output and supplied to a display device.  Thus, the data stored in the forecast/display frame memory section (103) can be compressed to reduce the size of memory capacity.
