Abstract: L'invention concerne un système de transmission de programmation numérique, comprenant une source de programmes fournissant des informations numériques, des circuits permettant de moduler les informations numériques sur un vecteur visuel modulé par programmation télévisuelle analogique, et un transmetteur visuel couplé aux circuits de modulation. Grâce à un procédé de modulation de phase, la phase du système module les informations numériques d'un vecteur visuel, réduit les fréquences de la bande de base du vecteur visuel à modulation de phase, et module en amplitude le vecteur vidéo à modulation de phase sur un signal vidéo. Les signaux vidéo amplifiés et codés sont combinés à un signal audio amplifié avant leur transmission. Grâce à un procédé d'addition, le système module les bandes latérales du vecteur vidéo à l'aide des informations numériques, et module en amplitude le signal vidéo sur le vecteur vidéo. Les bandes latérales à modulation de données subissent un décalage de phase de manière à être en quadrature avec le signal vidéo à modulation d'amplitude. Le système combine le vecteur vidéo à modulation d'amplitude et les bandes latérales de quadrature à modulation de données. Grâce à un procédé mixte de multiplication/addition, le système réalise la modulation de phase et l'addition des bandes latérales de quadrature, ce qui permet d'obtenir un résultat optimisé.

Inventor: LI SHULONG
IPC: B32B27/12
Filed: 2000-06-15
Abstract: This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. The first layer (base coat), being in contact with the airbag surface, comprises a composition of at least one coating material which may comprise up to 30 % by parts of the total amount of material in the first layer of a silicone resin (which is preferably a polyurethane) which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.

Title: Packaging for adhesive-bandage to allow one-handed application
Inventor: SCHROEDER MARK R
IPC: A61F13/00
Filed: 1999-11-05
Abstract: A packaged article including an adhe-sive-sided article (1), such as an adhesive bandage, a release paper (13) facing the adhesive side (3) thereof, and packaging top support (4) and bottom backing (9) sheets. The facing sur-faces of the top support (4) and bottom back-ing (9) sheets peripherally surrounding the ad-hesive-sided article (l) have cohesive surfaces (6, 7 and 10). An adhesive strip, preferably a double-sided adhesive strip (5), attaches the non-adhesive side (2) of the adhesive-sided ar-ticle (1) to the top support sheet (4). Relative strength adhesives and cohesives are employed so that the bottom sheet (9) and top sheet (4) are first separated to leave the top sheet (4) and adhesive-sided article (1) together. The top sheet (4) is used as an applicator for plac-ing the article (1) onto a target surface (20), such as a patient's skin. The cohesive surface (6, 7) of the top sheet (4) surrounding the ar-ticle (1) does not adhere to the target surface (20). At the time, however, the top sheet "pops up" from the article (1) now adhered in place.  The top sheet (4) is then removed by breaking the bond of the adhesive strip (5). All of this is conveniently done with one hand. A method of making the package and a convenient as-semblage of packages similar to a matchbook assemblage (17) is also included.

Abstract: Models in compositional state systems are reduced by defining a set of events of interest and defining a transitive effect machine for components in the model relative to the events of interest. A transitive effect machine for a given component is defined by determining the transitive effects of events in the given component on other components in the model.   Transitive effect machines are defined relative to reduced versions of other components in the model. The transitive effect machines are defined by succesive assumptions of the reduced versions of the other components in the model and successively defined approximations to the transitive effect machine.
