Title: System for compression and decompression of video data using discrete cosine transform and coding techniques
Inventor: BALKANSKI ALEXANDRE
IPC: H04N11/04
Filed: 1991-03-13
Abstract: A SYSTEM FOR COMPRESSION AND DECOMPRESSION OF VIDEO DATA USING DISCRETE COSINE TRANSFORM AND                  CODING TECHNIQUES                  Alexandre Balkanski Steve Purcell James Kirkpatrick ABSTRACT OF THE DISCLOSURE     A digital video compression system and an apparatus implementing this system are disclosed.  Specifically, matrices of pixels in the RGB signal format are converted into YUV representation, including a step of selectively sampling the chrominance components.  The signals are then subjected to a discrete cosine transform (DCT).  A circuitry implementing the DCT in a pipelined architecture is pro-vided.  A quantitation step eliminates DCT coefficients hav-ing amplitude below a set of preset thresholds.  The video signal is further compressed by coding the elements of the quantized matrices in a zig-zag manner.  This representation is further compressed by Huffman codes.  Decompression of the signal is substantially the reverse of compression steps.  The inverse discrete cosine transform (IDCT) may be implemented by the DCT circuit.  Circuits for implementing RGB to YUV conversion, DCT, quantization, coding and their decompression counterparts are disclosed.  The circuits may be implemented in the form an integrated circuit chip.

IPC: B64C27/18
Filed: 1991-09-26
Abstract: Turboréacteurs montés sur pales d'hélicoptères. Il s'agit d'installer des turboréacteurs sur l'extrémité extérieure des pales d'un hélicoptère de façon à faire tourner celles-ci. Le rotor de l'hélicoptère ne serait plus moteur: donc les forces de torsion exercées sur l'arbre ne seraient dûes qu'au frottement. La cabine serait plus spacieuse et mieux insonorisée car la turbine ne serait plus à l'intérieur de l'appareil. Vu que l'arbre du rotor n'est plus moteur, la petite hélice arrière n'est plus nécessaire. Le réservoir à carburant serait situé au dessus du rotor, les canalisations seraient insérées dans les pales. Le carburant partirait du réservoir par la force centrifuge, traverserait les pales jusqu'à leurs extrémités pour entrer dans les turboréacteurs.

According  to  the  present invention, a  glass  plate  (1)  is imprinted  by  means  of printing technology with  a  layer  of pattern  (2)  in coloured printing ink or of  vitreous  enamel.      After  heating to make it become solidified or  sintering,  the glass  surface  or the  printed layer surface is  processed  to have  a  layer of adhered transparent resin (3) .  Then  it  is added  a  layer of resin (5) in grating relief  with  reflexive metal  film (4) . A plate of printed glass  grating  decorative panel is thus obtained. This product can overcome  shortcomings in  prior arts. It merges into a single whole  the  simpleness analogue  to  those of the natural stones, such as  marble  and granite  and of ceramic tiles, or the artistic pattern  of  the imprinted  glass  and the magnificent optical  effects  of  the grating.
