Patent CA-2189122-A1 (CA)
Inventor: COELHO ROHAN A F
IPC: H04N21/44
Filed: 1995-04-28
Abstract: Dans un procédé et un appareil de décompression d'un signal vidéo numérique représentatif d'une séquence d'entrée de trames vidéo numériques, on envoie un signal vidéo numérique à un décompresseur vidéo ayant un taux de décompression de trame cible qui est fixé initialement au taux de trame maximum possible. La sortie du décompresseur vidéo est contrôlée afin de déterminer si le décompresseur vidéo génère de manière synchronisée la séquence de sortie des trames vidéo numériques. Si le décompresseur vidéo ne le fait pas, il est alors ajusté en retirant de la séquence de sortie au moins une trame présente dans la séquence d'entrée. Une valeur de trame manquante est générée en réponse à chaque groupe d'une ou de plusieurs trames retirées, et les écarts de la valeur de trames manquantes sont contrôlées. Le taux de décompression cible du décompresseur vidéo est ajusté de manière sélective à la baisse en réponse aux écarts de la valeur d'absence de trames.

Title: Street hockey suit
Inventor: GRAY JOANNE
IPC: A41D13/02
Filed: 1997-07-29
Abstract: In the game of Hockey, you can always count on injuries and mishaps.  With the invention of this STREET HOCKEY SUIT, we have reduced the chances of injuries and mishaps, and hopefully aided with proper equiptment like, helmets, hockey gloves, and roller knee and elbow pads, will also promote safety.  The reason we invented the STREET HOCKEY SUIT, was because so many players have been seriously cut or bruised by the hardness of the hockey ball. If you ask any child or child at heart, what they prefer to play street hockey with, they will tell you the hard hockey ball.  The hockey ball rolls better and doesn't bounce around like a tennis ball, but they really don't have much choice but use the tennis ball because it doesn't hurt near as much as the hockey ball. But with the STREET HOCKEY SUIT that problem is eliminated.
