Abstract: A method for manufacture of a complex component includes construction of the component from a metal material in an additive manufacturing method with at least one cavity segment that has a cavity open on at least one side and defined by an interior surface of the component, formation of an auxiliary electrode during construction of the component, formation of one or a plurality of supporting structures that connect the auxiliary electrode to the interior surface of the component during the construction of the component, electrical insulation of the auxiliary electrode from the interior surface by separating the supporting structures from the interior surface or from the auxiliary electrode, and performance of an electro-polishing of the interior surface in an electrolyte bath by connecting the component and the auxiliary electrode to different poles of an electric voltage source.

Abstract: A structural component, in particular for an aircraft, has a grid structure which is constructed from rod elements, wherein the rod elements form basic units which are repeated within the grid structure and each have the same polyhedral outer shape. A first number of reinforcing elements are provided in a first region of the grid structure, and a second number of reinforcing elements are provided in a second region of the grid structure, wherein the second number of reinforcing elements is smaller than the first number of reinforcing elements.

Abstract: A method and system to control power consumption of a display system includes using a low power display and a normal power display. The low power display may be a reflective display and may be used when the environment is bright. The normal power display may be a transmissive display and may be used when the environment is not as bright.

Abstract: An isokinetic testing machine is disclosed having a support frame, a sub-assembly disposed on the support frame, a power source operably disposed within the sub-assembly, a first main arm having a proximal apex end and a distal end, the first main arm distal end is pivotally attached to the power source, a first torque arm pivotally and releasably attached to the first main arm proximal apex end, a user support area disposed on the support frame proximate to the first torque arm proximal end, a first load cell disposed within the first torque arm for measuring the torque when the first torque arm pivots, and wherein the first main arm and the torque arm can pivot and are configured to a desired position for isokinetic testing of the knees, the shoulders, and the back of the user.
