Abstract: Examples of augmented reality (AR) environment control advantageously employ multi-factor intention determination and include: performing a multi-factor intention determination for summoning a control object (e.g., a menu, a keyboard, or an input panel) using a set of indications in an AR environment, the set of indications comprising a plurality of indications (e.g., two or more of a palm-facing gesture, an eye gaze, a head gaze, and a finger position simultaneously); and based on at least the set of indications indicating a summoning request by a user, displaying the control object in a position proximate to the user in the AR environment (e.g., docked to a hand of the user). Some examples continue displaying the control object while at least one indication remains, and continue displaying the control object during a timer period if one of the indications is lost.

Abstract: A method produces a uretonimine-modified isocyanate composition having increased low-temperature tolerance. The method comprises providing a first polyisocyanate composition having two or more isocyanate groups and comprising 4,4?-diphenylmethane diisocyanate (MDI) and reacting the first polyisocyanate composition at a temperature of from about 90° C. to about 115° C. and in the presence of a catalyst such that the isocyanate groups form carbodiimides for forming uretonimine and uretonimine oligomers. The reaction of the first polyisocyanate composition is quenched with a quenching agent to produce an intermediate composition having an intermediate isocyanate value of from about 21.0 to about 26.0. The intermediate composition is blended with a second isocyanate composition to form a stable uretonimine-modified isocyanate composition.

Abstract: A uretonimine-modified isocyanate composition has reduced color. The uretonimine-modified isocyanate composition comprises a polyisocyanate composition having two or more isocyanate groups and comprising 4,4?-diphenylmethane diisocyanate (MDI) and a catalyst for catalyzing a reaction of the isocyanate groups to form carbodiimides available for forming uretonimines and uretonimine oligomers. A first quenching agent partially quenches the reaction of the isocyanate groups to inhibit formation of the carbodiimides thereby inhibiting additional formation of uretonimines and uretonimine oligomers and a second quenching agent different than the first quenching agent quenches the reaction of the isocyanate groups to further inhibit formation of the carbodiimides thereby further inhibiting additional formation of uretonimines and uretonimine oligomers. A method of forming the uretonimine-modified isocyanate composition is also disclosed.

Abstract: An isocyanate prepolymer is made by providing an isocyanate component. A phosphite that is free of active hydrogen groups is introduced into the isocyanate component. An isocyanate-reactive component and a stoichiometric excess of the isocyanate component are reacted in the presence of the phosphite to make the isocyanate prepolymer. A polyurethane foam is made by reacting the isocyanate prepolymer and a second isocyanate-reactive component in the presence of a blowing agent. A composite article is made by forming an elastomeric layer on the outer surface of the polyurethane foam core. Due to the presence of the phosphite during reaction of the isocyanate component and the isocyanate-reactive component to make the isocyanate prepolymer, more efficient use of the phosphite is made, and the full color-reducing effect of the phosphite on the polyurethane foam is realized.

Abstract: A lignocellulosic composite material and a method for preparing the lignocellulosic composite material are disclosed. The composite material includes lignocellulosic particles and a binder resin being a mixture of a polyisocyanate component and a release agent. The release agent is formed from a first component having hydroxyl groups and a second component having isocyanate groups in excess of the hydroxyl groups. The first component is selected from at least one of i) an acid phosphate and ii) pyrophosphates represented by those derived from the acid phosphates (i) and mixtures of the acid phosphates (i). The first component is passivated by mixing it with the second component which is preferably monomeric diphenylmethane diisocyanate selected from at least one of diphenylmethane-4,4?-diisocyanate, diphenylmethane-2,4?-diisocyanate, and diphenylmethane-2,2?-diisocyanate.

Abstract: A method produces a uretonimine-modified isocyanate composition having increased low-temperature tolerance. The method comprises providing a polyisocyanate composition comprising 4,4?-diphenylmethane diisocyanate (MDI) and reacting the polyisocyanate composition at a temperature of from about 90° C. to about 115° C. in the presence of a catalyst, and optionally a co-catalyst, such that the isocyanate groups react to form uretonimine oligomers. The reaction of the polyisocyanate composition is quenched with a quenching agent to produce an intermediate composition having an intermediate isocyanate value from about 25.5 to about 28.5. A second polyisocyanate composition is added to the intermediate composition in an amount sufficient to produce the uretonimine-modified isocyanate composition having a final isocyanate value of from about 29.0 to about 29.5.

Abstract: Apertured plates are mounted to a bridge structure and cooperate with a mirror system to reflect a laser beam from a laser gun to a laser receiver that is coupled to processing circuitry coupled to a modem that is in turn coupled to a central monitoring station through a telephone line. There are a first pair of aperture plates fixedly secured to one side of a first vertical column and a second vertical column of the bridge and are aligned with each other and a first mirror of the mirror system. A second pair of aperture plates are fixedly secured to another side of the first vertical column and the second vertical column of the bridge and are aligned with each other and a second mirror of the mirror system in order to provide for a forward and reverse passage of the laser beam for detecting the sway and deflection of the bridge.
