Abstract: A system includes a processor and a memory coupled to the processor. The memory stores instructions that cause the processor to determine a first motion envelope of an object. The first motion envelope corresponds to a kinematic envelope of positions of the object which are achievable. The instructions also cause the processor to determine an operational envelope of the object based on an intersection of the first motion envelope and a second motion envelope of the object. The second motion envelope corresponds to a range of motion of the object constrained by dynamic motion limits of the object, and the operational envelope is indicative of a range of motion of the object during operation of the object. The instructions further cause the processor to generate a virtual model of the object based on the operational envelope. The virtual model is used to virtually model operation of the object.

Abstract: Method, system, and computer program product for simulating the layout and flow of a manufacturing facility. An initial facility layout concept and a baseline input data set are received which define placement and movement of virtual objects within a virtual facility model. At least one of several analyses is performed based on the initial facility layout concept and the baseline input data set. An event flow analysis that outputs timing for movement of the objects from the initial positions may be performed. A geometric flow analysis that outputs interactions between the objects resulting from the movements from the initial positions may be performed. An ergonomic analysis that outputs human postures and motions resulting from interactions with objects may be performed. A simulated flow model for the manufacturing facility is generated. A three-dimensional virtual environment of the simulated flow model is generated and output for display.

Abstract: Methods, apparatus, and systems for automated reflector tuning include combining high precision automated photogrammetric measurement with high precision servo actuator positioning control of a reflector surface using custom optimizing control software to produce a novel, fully automated satellite reflector alignment tuning system. Precise adjustment to the shape of the reflecting surface of an antenna reflector (reflector tuning) can be essential for a satellite reflector antenna to meet electrical performance requirements, usually requiring a shape accurate to within 0.004 inches RMS. The automated reflector tuning may include determining a set of characterization coefficients by precisely measuring the response of the reflector shape to actuator movements, and using the characterization coefficients in a mathematical analysis to determine optimal actuator movements to achieve a required shape of the reflector surface.
