Abstract: A power-saving block may be isolated from a remainder of a digital circuit. To save power, the power-saving block may be powered down when not in use. To prevent the power-down process from creating metastable states in the remainder of the digital circuit, appropriate isolation gates may separate outputs of the power-saving block from the remainder of the digital circuit. Signals may be sent to the power-saving block to ensure that the output signals from the power-saving block are always the same value during the power-down process. The isolation gates may be chosen based on the value expected on the output signals during the power-down process. Assertions may be used to confirm that the correct isolation gates were selected.

Abstract: A multi-end fiber glass roving comprises a plurality of fiber glass ends and at least one bicomponent string binder. The bicomponent string binder may comprise at least one bundle of bicomponent string binder filaments, each filament having a core and an outer sheath.

Abstract: The present invention provides a mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The mat includes a primary, supporting layer having a plurality of randomly oriented essentially continuous glass fiber strands. The primary layer has about 1 to about 10 weight percent of the mat on a total solids basis. The mat also includes a secondary layer positioned upon and supported by a surface of the primary layer, the secondary layer including a plurality of glass fiber strands. The mean average length of the glass fiber strands of the secondary layer ranges from about 20 to about 125 millimeters. The strands of the primary layer are entangled with the strands of the secondary layer by needling the primary layer and the secondary layer together.

Abstract: Chemically treated glass fibers of the present invention provide good processing properties in reinforcing thermosetting polymers while resulting in fiber reinforced thermosetting materials having good strength properties. The chemically treated glass fibers have a dried residue of an aqueous chemical treating composition having: two film forming polymers, at least an acryloxy alkyl trialkoxysilane, a fiber lubricant and polyester curing agent and water. One film forming polymer is a polyvinylacetate copolymer having a low solubility in acetone and the other film forming polymer is unsaturated, curable, essentially linear polyester polymer. The fiber lubricant is a nonionic polyethylene-containing polymer or a cationic lubricant like polyalkylene polyamine polyamino amide, and partially amidated polyalkylenimines and mixtures thereof present in an effective lubricating amount.

Abstract: Chemically treated glass fiber reinforcement for thermosetting polymers having a moisture reduced residue of an aqueous chemical treating composition consisting essentially of a vinyl acetate-organosilane copolymer, a vinyl silane coupling agent, an amino-organo silane coupling agent, at least one cationic lubricant, polyoxyethylene, an antistatic agent, an aqueous dispersible or emulsifiable wax with a surfactant and water.
