Title: Multi-purpose measuring tool
Inventor: MOE RICHARD J
IPC: G01B3/10
Filed: 1999-07-02
Granted: 2002-07-30
Abstract: A multi-purpose measuring tool has an elongate base and arm pivotally connected at rounded ends thereof in an angularly variable relation to perform multipl e functions, including measuring inclines, measuring corner angles, measuring distances, use as a square, use as a bevel gauge and use as a torpedo level. A retractable measuring tape housed within the arm has a terminal finger gripping end adapted to be pulle d away from the arm and removably attached to a distal end of the base. The measuring ta pe is dual purpose in that one side of the tape is used for determining the angle of th e arm relative to the base to perform some of the above functions, and the other side of the tape is used for traditional linear distance measurements. The tool's base includes a "vertical" bubble level and the arm includes a "horizontal" bubble level to perform some of the abov e functions.

Title: Two tier venetian blind
Inventor: TRONSGARD KEN
IPC: E06B9/24
Filed: 1999-07-20
Granted: 2004-10-12
Abstract: A two tier venetian blind comprises an upper and a lower tier of slats suspended from a blind control mechanism; a front upper control cord and a back upper control cord for tilting the upper tier of slats; a front lower control cord and a back lower control cord for tilting the lower tier of slats; and a lift cord passing through a lift cord hole in each slat in the upper and lower tiers of slats.

Abstract: L'invention concerne un procédé et un système de stockage d'une alimentation continue d'informations vidéo. Selon un aspect de l'invention, l'alimentation continue est codée en un format vidéo numérique afin de produire un train de données numériques. Une série de fichiers de contenu est créée par exécution répétée des étapes consistant (1) à stocker le train de données numériques dans un fichier courant, et (2) à établir un nouveau fichier comme fichier courant lorsque le fichier courant satisfait une condition prédéterminée. Si la série des fichiers de contenu contient plus d'une quantité prédéterminée de l'alimentation continue, le fichier de contenu le plus vieux dans la série des fichiers de contenu est effacé. Des informations de repère indiquant des informations relatives contenues dans le train de données numériques sont générées. Les informations de repère comprennent des horodatations indiquant la chronologie des images par rapport au début du train de données numériques. Une valeur de temps initiale indique un temps absolu correspondant au début du train de données numériques. Lorsqu'une demande d'un client pour que la reproduction commence à un temps absolu spécifié est reçue, la valeur de temps initiale est soustraite du temps absolu spécifié afin de déterminer un temps relatif. Les informations de repère sont utilisées pour identifier un point dans le train de données numériques correspondant au temps relatif. Le train de données numériques est ensuite transmis au client commençant au point dans le train de données numériques correspondant au temps relatif.
