Abstract: The subject tiltrotor aircraft has three modes of operation: airplane mode, helicopter mode, and transition mode. A tilting mast, which transitions the aircraft between airplane mode and helicopter mode, is controlled by systems that allow selective movement of the rotor blades between the flight modes. A hub couples the rotor blades to the tilting mast such that torque and thrust are transferred, while allowing rotor thrust vector tilting. A main swash plate controls rotor thrust vector direction. Pitch horns are coupled to the rotor blades and the main swash plate via pitch links such that swash plate inputs are communicated to the rotor blades. The pitch links are coupled at “delta-3” values that are not optimum. A feedback swash plate and feedback links receive disk tilting inputs from the rotor blades, and supply inputs to the main swash plate, which compensates for the less than optimum delta-3 coupling.

Abstract: The Location Enhanced Information Deliver System Architecture (LEIA) customizes the information that is displayed to an information recipient based on optimizing a match between information purveyors, such as advertisers, and the information recipients who are local to an information delivery system. The present location enhanced information delivery system presents the information most suited to the real current audience, as measured by location information systems, rather than to a static predicted audience. While the preferred embodiment discloses a beaconing-style wireless technology, the system concept is easily extensible both to other location-information systems, such as license-plate scanning with cameras, and to utilizing the location-information for private displays of information in addition to public displays of information.

Abstract: A well treatment tool is installed along the sucker rod string of a well, within the surrounding production tube string. The tool provides for the distribution of a treatment fluid (solvent, etc.) within the fluid being pumped or flowing from the well. The tool receives treatment fluid through the hollow sucker rod string, and distributes the fluid through a valve which is set at a predetermined pressure. When the treatment fluid pumped down the sucker rod string from the surface exceeds the predetermined opening pressure of the valve, the treatment fluid is distributed into the production tube string through one or more passages in the tool. The present tool may be used simultaneously with well production, with fluid (oil, etc.) rising up the production tube string, carrying the treatment fluid therewith. The treatment fluid is thus distributed throughout the local fluid processing system, including pipelines from the well, any initial treatment operations, and any storage tanks.

Abstract: An apparatus for supporting modular and cooperating components which includes a base assembly, a work surface, a vertical support pole extending upward from the work surface, at least one bushing concentrically engaging the vertical support pole at a particular axial location, at least one support arm extending radially outward from the bushing, and at least one support surface secured to the support arms in a position substantially orthogonal to the support pole, which minimizes the space requirements for supporting modular and cooperating components, particularly in an office environment. The support apparatus according to the present invention increases the functionality of the modular and cooperating components without exposing the modular and cooperating components to unnecessary risk of harm.

Abstract: The present invention is directed to a decorative item. The decorative item includes a number of components which cooperate together. A layer of luminescent material is provided. The layer of luminescent material is preferably, but not necessarily, a substantially rigid and planar carrier. A translucent image is affixed to the layer of luminescent material. The decorative item is operable in a plurality of modes of operation, including an excitation mode of operation and a delayed light emission mode of operation. During the excitation mode of operation, the decorative item is exposed to a source of exciting energy, such as light. In the delayed light emission mode of operation, the layer of luminescent material generates a phosphorescent light emission, after the source of exciting energy is removed, which passes through the translucent image and makes it visible in low light conditions.

Abstract: A monitoring and control system for use in curing composite materials includes a model for a workpiece being cured. The model calculates current internal states of the workpiece and predicts, based upon past and current states of the workpiece, future states of the cure process. These future states are represented as virtual inputs to the controller, which controls operation of the cure process based upon both real and virtual inputs. Cure rates are affected by both external temperatures and internal heat generated by the curing process itself. The internally generated heat is considered by the model when calculating current states and predicting future states. By projecting the cure state into the future, problems caused by high cure rates can be avoided. In addition, pressure can be optimally controlled in response to estimated internal material state.
