Abstract:

There is provided a variable pressure roller system for installing a preform having contact surfaces onto a configuration of a mold surface by applying pressure thereon. The roller system of the present invention comprises a roller carriage. A grasping handle may be mounted to the roller carriage. Moreover, the roller system may further comprise a plurality of rollers, wherein each respective one of the plurality of rollers is defined by a weight to generate a specific pressure corresponding thereto. Furthermore, each respective one of the plurality of rollers may be removably engageable to the roller carriage. Each respective one of the plurality of rollers may be adapted to uniformly distribute the specific pressure corresponding thereto on the contact surfaces for conforming the preform to the configuration of the mold surface when engaged to the roller carriage.

Abstract:

Methods of forming shaped adhesive fillets are disclosed. The adhesive fillets may be made by stacking multiple layers of adhesive sheets, consolidating the stacked layers, cutting strips from the consolidated layers, and forming the strips into adhesive fillets having desired cross sectional shapes. The fillets may be formed by feeding the strips through an apparatus comprising opposing rollers and a catcher, which facilitates release of the adhesive fillets from the rollers. The formed adhesive fillets are useful for applications such as stiffened panels for aircraft.

US Classification:

714726, 714733, 716103

Abstract:

A process for improving design-limited yield by collecting test fail data, converting to electrical faults, and localizing to physical area on semiconductor die. The steps of identifying an area on a wafer containing a fault to enable the analysis of specific defects, accumulating data suitable for yield monitoring analysis based on pattern test failures logged on scan cells in scan chains on automatic test equipment, and translating scan cell and scan chain failure reports to geometric locations of electrical structures on wafers.

US Classification:

249 83

Abstract:

Method and apparatus for making a fiber reinforced composite wherein fiber reinforcement material is disposed in a molding cavity formed between a substantially rigid molding tool and a compliant molding tool in a pressurizable chamber of a pressure vessel, such as an autoclave. Uncured polymer resin is introduced under pressure to the molding cavity by a resin pump disposed in the chamber or external thereof so as to initially infiltrate the fiber reinforcement material with the resin. The chamber is gas pressurized to provide isostatic pressure on the rigid and compliant tools during resin infiltration of the fiber reinforcement material. The resin-infiltrated fiber reinforcement material then is heated in the chamber to cure the resin matrix. Large surface area composites of the aerospace skin structure type can be made using the present invention.

International Classification:

G06Q 30/02

Abstract:

Response latencies in a system are reduced by performing a plurality of auctions in parallel using respective processing threads. An ad call associated with an impression for a webpage requested by a user computer is received by the system. Impression information is obtained based on the ad call, which is then used to determine a subset of multiple potential impression providers that are to participate in an auction for the impression. Behavior models may be used to determine the subset, while floor or reserve price models are used to set a floor/reserve price for each potential impression provider in the subset. Bid requests are sent out in parallel to the subset of potential impression providers using the respective floor/reserve prices, with a thread allocated to each bid request. The models can be further trained on information obtained from the received bid responses and impression information.
