Abstract: Finite element methods for compensating for springback in aircraft parts meet the visual appearance and aerodynamics of complex parts including those made of fabricated sheet metal. The methods can be used to make narrow parts (e.g., leading edge and slats) and double negative curvature parts, and do not need to leave marks on the surface of the sheet so that visual aspects are not adversely affected. The point to point compensation technique uses approach equations with constants adjustable for curves. The constant(s) used depend on geometry and type of forming (e.g., stretch or hydraulic press). Use of mechanical properties of the material is not required.

Abstract: This invention relates to methods and systems for limiting consumption, particularly power consumption, more particularly by appliances in a building, and is generally suitable for integration with building management systems. Embodiments of the invention provide arrangements in which the aggregated power load of a plurality of appliances is capped to a selected value (which may be arbitrary, or may be dictated by conditions) while seeking to minimize the deviation from target environmental conditions within the building through a combination of distributed decision making by the appliances themselves and centralized orchestration, which may be informed by real-time sensor readings and/or known properties of the building. The distributed decision-making by individual devices may be based on projected deviation from the target conditions after a period of activity or inactivity but with a central controller which determines which devices should be switched on.

Abstract: In a work machine which includes a working head including a lifting and lowering unit including a working device and a first lifting and lowering device which lifts and lowers the working device, and a second lifting and lowering device which lifts and lowers the lifting and lowering unit, a positional deviation (?x, ?y) of the working device in a direction which is perpendicular to a lifting and lowering direction is eliminated. Since the positional deviation is caused by both an inclination of a lifting and lowering axis line L1 of the working device by the first lifting and lowering device and an inclination of a lifting and lowering axis line L2 of the lifting and lowering unit by the second lifting and lowering device, based on positional deviation data a target moving position is corrected.
