Abstract: Motion control using electromagnetic forces. The control of motion in unpowered apparatus and an apparatus driven by electric motors and/or other prime movers utilizes electromagnetic force/torque for control of motion. One objective is to extend the domain of electric motor speed control, traditionally characterized by electronic techniques, to small apparatus such as bubble vibration toys, paper dispensers, toothbrushes and other appliances.

Abstract: This invention relates to inventory optimization under uncertainty wherein uncertainty is represented in a constraint based framework derived from basic economic principles. This approach offers the ability to use information theoretic concepts to quantify the amount of information used in the optimization. The invention extends the state-of-art to include optimal inventory optimization when relevant supply chain variables are correlated. It can be used in other contexts also.

Abstract: In this research, we propose to extend the robust optimization technique and target it for problems encountered in supply chain management. Our method represents uncertainty as polyhedral uncertainty sets made of simple linear constraints derivable from macroscopic economic data. We avoid the probability distribution estimation of stochastic programming. The constraints in our approach are intuitive and meaningful. This representation of uncertainty is applied to capacity planning and inventory optimization problems in supply chains. The representation of uncertainty is the unique feature that drives this research. It has led us to explore different problems in capacity/inventory planning under this new paradigm. A decision support system package has been developed, which can conveniently interface to manufacturing/firm data warehouses, inferring and analyzing constraints from historical data, analyzing performance (worst case/best case), and optimizing plans.

Abstract: An apparatus has (a) a first component having one or more electromagnetic elements and (b) a second component having one or more electromagnetic elements and movably coupled to the first component. The second component moves with respect to the first component in a cyclical manner. The one or more electromagnetic elements of the first component interacts with the one or more electromagnetic elements of the second component during each of one or more cycles of motion of the second component with respect to the first component such that, when a constant force profile is applied to move the second component with respect to the first component, the speed of motion increases and decreases one or more times during each cycle of motion due to different levels of electromagnetic interaction between the electromagnetic elements within each cycle of motion.
