Abstract: Partially crosslinked polyurethane polymers comprising diisocyanates and aliphatic hydrocarbon soft segments with a short-chain diol chain extender and a multifunctional amine and/or alcohol crosslinker to provide a polyurethane polymer with useful properties for the production of medical implant devices such as heart valves, are described. The polymers have an unexpected linear elastic region in a range from 5-100% and preferably between 10-35%. In some embodiments the polyurethanes are a thermally convertible gel formulation which may be converted to a liquid formulation by extended heating to render the polymer suitable for solvent processing techniques such as casting, spraying, spinning, etc. The invention also provides for living hinge polyurethane polymers which are thermally modifiable from a gel to a liquid and reaction injection moulded (RIM) polyurethanes with an enhanced flex life.

Abstract: An assembly of thermoplastic parts for forming a final composite part is presented where the assembly includes at least two prefabricated shells fabricated of thermoplastic. Each prefabricated shell has substantially the same shape as the final composite part and where the shapes of the prefabricated shells have dimensions that allow the prefabricated shells to be assembled into a nest for placement into a mold.

Abstract: A method, system, and computer-readable storage medium are disclosed for boundary-aligned anti-aliasing. In one embodiment, artwork input comprising a first set of one or more graphical elements and a second set of one or more graphical elements may be received. The first set may comprise at least one horizontal or vertical line segment. Each graphical element in the first set of one or more graphical elements may be automatically aligned to pixel boundaries based on a pixel resolution of a target imaging device. An anti-aliasing function may be applied to generate a selectively anti-aliased artwork based on the artwork input. Applying the anti-aliasing function may comprise applying anti-aliasing effects to the second set of one or more graphical elements and not to the first set of one or more graphical elements. The selectively anti-aliased artwork may be displayed on the target imaging device.

Abstract: A touchscreen device may be configured to facilitate drawing lines, circles, and shapes through use of a guide device placed on the touchscreen. The touchscreen device may detect the position and orientation of the guide device, for example, by determining an axis of the guide device based on a set of locations at which the guide device triggered contact signals on the touchscreen. Based on the detected position and orientation of the guide device on its touchscreen, the touchscreen device may display one or more lines or shapes on the touchscreen. If a user traces a portion of such a displayed line or shape, the touchscreen device may display the traced portion. A button on the guide device may be configured to cause the touchscreen device to sequentially display available lines and shapes. The user may also configure the button to display one or more user-generated shapes.

Abstract: An apparatus and method for making a mold or mold face includes a container having at least one opening. The apparatus also includes a flexible membrane that is retained to the container that extends across the opening of the container. The apparatus for making a mold further includes support media that is disposed within the container along with a vacuum valve that is connected to the container.

Abstract: The graphic file management system of the present invention provides users with the ability to control the complexity, flow, and quality (performance, ease of use, and scalability) of managing and usage of graphic files across enterprises. In particular, the system of the present invention allows for automated and dynamic repurposing (maintenance, use and manipulation) of large amounts of digital graphic data or files. The system comprises a server which can manipulate graphic files and establishes links to each graphic file, and a database on which the server stores the links. The server can create other formats of a particular graphic file and allows for amendments to graphic files to be tracked.

Abstract: Reaction injection molded (RIM) members and a method for forming such members are provided. The members can be formed in a mold cavity defining a contour that corresponds to the desired contour of the members. A foam material, such as a combination of polyol and isocyanate is injected into the cavity with a blowing agent so that the foam material expands to form the low density member. The average density of the member can be less than about 6 pounds per cubic foot.

Abstract: A mobile platform interior panel is provided that includes a body formed by a low pressure injection process and at least one of a duct and a layer of insulation integrated with the body. The low pressure injection process allows the duct and insulation to be integrated with the body simultaneously with the forming of the panel. More specifically, the duct is integrated with the panel by forming at least one internal cavity within the panel as the panel is formed. Additionally, the insulation is integrated with the panel by forming the panel using a low pressure injection material having desired insulative properties.
