摘要:
A connection device for random connection of a first member of first transmission/reception units with a second number of second transmission/reception units has a switching matrix that includes a third number of controllable micromechanical switching elements that are respectively activatable to establish a connection between one of the first transmission/reception units and one of the second transmission/reception units. A control circuit selectively activates the respective micromechanical switching elements to selectively establish respective connections between the first number of first transmission/reception units and the second number of transmission/reception units.
摘要:
A device for converting mechanical energy into electrical energy has first electrode formed of a first material having a first work function for a charge carrier, and a second electrode formed of a second material having a second work function for a charge carrier, the second work function being different from the first work function. The first electrode and the second electrode are interconnected by a first load circuit in an electroconductive manner. The second electrode is arranged at a variable distance from the first electrode.
摘要:
A workpiece having a bearing surface with at least one convex curvature and an opposing workpiece having an opposing bearing surface with a concave curvature essentially inverse to the convex curvature of the bearing surface are moved by a device relative to each other in such a manner that the convex curvature of the bearing surface can be guided into the concave curvature of the opposing bearing surface. To convert energy, a bending element, such as a disk bender, is located in a space between the bearing surface and the opposing bearing surface so that the movement of the workpiece and the opposing workpiece relative to each other results in the bending of the bending element. Mechanical energy can be converted into electrical energy with higher efficiency by using a disk bender. The workpieces and the bearing surfaces thereof are formed to provide overload protection.
