Abstract: An arrangement for anchoring a roof of a building so that it can resist wind forces captures each roof truss, or other roof framing member, under a wire rope passed through a sequence of eyebolts protruding above a top plate of one of the walls of. Each of the eyes is the upper portion of one of a plurality of rod assemblies, each of which is connected to a respective one of a plurality of anchors disposed beneath the wall. A turnbuckle connecting each rod assembly to a respective eyebolt is used to draw the eyebolt down against the top plate and hence apply tension to the wire rope.

Abstract: A watermark information embedding method, and apparatus, capable of suppressing the quality degradation of contents and increasing the survivability of embedded information. When embedding watermark information in moving picture data formed of a plurality of still picture frames arranged in time series, a motion vector representing a property specific to moving picture is detected for each of image blocks generated by dividing a target frame.      According to a motion quantity, a pixel change factor specifying rule is selected for each block. Out of pixels permitted to be changed in luminance depending upon the state of an image in each block representing a property specific to still picture, as many pixels as a number specified by the selected rule are selected. Luminance change processing for forming watermark information is conducted on the selected pixels.

Granted: 2006-09-26
Abstract: L'invention concerne un système d'administration gastro-intestinal. Ledit système comprend un médicament combiné à un noyau de matière gonflable, ledit noyau étant enrobé d'une matière de revêtement insoluble dans l'eau ou relativement insoluble dans l'eau à l'intérieur de laquelle est emprisonnée la matière en particules insoluble dans l'eau. Lorsque le dispositif d'administration pénètre dans le tractus gastro-intestinal, la matière particulaire absorbe du liquide et forme alors des canaux reliant le noyau contenant le médicament à l'extérieur du dispositif d'administration. Le liquide pénètre dans le noyau par ces canaux, lequel noyau gonfle au point de provoquer la rupture du revêtement. Lorsque la totalité du revêtement est détruite, le noyau se désagrège immédiatement, libérant ainsi la totalité ou la plupart du médicament au niveau d'un site spécifique. En contrôlant certains paramètres du dispositif, tels que la matière du noyau, la matière excipient renfermée dans le revêtement, et la matière particulaire, il est possible de contrôler de près l'emplacement au niveau duquel s'effectue la libération du médicament. Aussi, l'invention concerne-t-elle également un procédé d'utilisation du dispositif pour le traitement de maladies par la libération de médicaments au niveau du tractus gastro-intestinal, et ce de façon précise aussi bien dans l'espace que dans le temps.
