摘要:
A film for a screen has a light transmitting substrate and a plurality of structures disposed on the substrate. An optical material at least partially fills cavities between the structures. A method of forming a film includes providing a light transmitting substrate having a plurality of structures disposed thereon and at least partially filling the cavities therebetween with an optical material.

摘要:
A composition having at least about 10 percent perfluoroalkylsulfonamideoethyl acrylate; at least about 5 percent aliphatic urethane acrylate oligomer; at least about 1 percent acrylate monomer; and less than about 84 percent other reactive and non-reactive components. The composition, with the addition of a light absorbing pigment, is particularly useful as a light absorbing adhesive in an optical element such as a rear projection screen that incorporates totally internally reflecting structures to disperse the light passing through the screen.

The present invention is a method of forming an optical film including the following steps: providing a first film of a first material, extruding a second material to form a second film in a molten state; maintaining the second film in a molten state; bringing the first film proximate the molten second film; patterning the molten second film to form a plurality of structures, the structures defining a plurality of cavities therebetween; and solidifying the molten second film.
摘要:
The present invention is a conveying apparatus for the bi-directional guidance of one or more objects, ingredients, products, containers, packs or packaging components from a primary location to a secondary location. Matter, such as the objects, ingredients, products, containers, packs or packaging component, supplied to the conveying apparatus from the primary location are monitored and corresponding speed and directional values are determined that are indicative of the relationship between matter supplied to the conveying apparatus and the matter being guided by the conveying apparatus to the secondary location. Based upon the speed and directional values, the conveying apparatus may be managed for bi-directional guidance of one or more objects from the primary location to the secondary location.

Systems, methods, apparatus, and computer program products are provided for monitoring the transfer of cargo, such as a shipping container, to and from a transporter, such as a truck. Identification codes are provided on the cargo and the transporter to aid in the identification of the cargo and the transporter. One or more identification code receiving devices, such as a camera, may be associated with a cargo moving apparatus, such as a crane, and configured to automatically capture the transporter identification code and the cargo identification code as the cargo is being transferred to or from the transporter. The transporter identification code and the cargo identification code can be associated with each other along with other information about the transfer in order to monitor the transfer. In this regard, identification information may be communicated to a shipping terminal's operating system to provide real-time information about one or more transfers occurring within a shipping terminal.

An electromagnetic protection sheath made of textile (10) is formed by conductive filaments extending in a first direction (X) and non-conductive filaments interlaced with the conductive filaments. Use in particular for shielding cables in aeronautical applications.
摘要:
Device for the translational guidance of a load and method for creating such a device. The guide device (1) comprises an elongate bed plate (2), a mobile carriage (6) which serves to support the load, and guide means (7) that allow the carriage (6) to move longitudinally in relation to the bed plate (2), said carriage (6) comprising a bottom plate (9) which is provided with through-cuts (10) intended to give it at least some lateral elasticity, and which is mounted on the bed plate (2) under lateral stress, as well as a platform (13) which is fixed to the top face of this bottom plate (9) at fixing points (14).
