摘要： A sensor arrangement for a sensor arrangement remotely readable by radio frequencies. The sensor arrangement includes an LC resonator that includes a capacitor and a coil, and a sensor element coupled to the LC resonator whose properties change as a function of a measurable quantity. A sensor element according to the invention does not form a direct galvanic contact with the LC resonator, rather the coupling is implemented capacitively or inductively.

摘要： This publication discloses a method for identifying items, such as sheets of paper, or packages, a resistance mark arrangement, and reading apparatus. According to the method a mark made of electrically conductive material on the item is read contactlessly, in order to identify the item (7), or determine its properties. According to the invention, the precise absolute or relative resistance value of at least one electrically conductive mark (6) is determined and the measured resistance value is converted, for example, with the aid of a coding table or calculation formula, into information depicting the identity or properties of the item.

摘要： A micromechanical sensor for measuring millimetric wave or microwave power, which sensor comprises a wave line for conducting the millimetric or microwave power and a part arranged to move and a fixed electrode, in such a way that the capacitance (C) between the part that is arranged to move and the fixed electrode couples to the wave power advancing in the wave line. According to the invention, the capacitance (C) between the part that is arranged to move and the fixed electrode is divided into at least two portions (C/n), which are located at a distance from each other, in such a way that the wave power advancing in the wave line couples to the portions (C/n) of the capacitance (C) consecutively and experiences the inductive load between the portions (C/n) of the capacitance (C). Thus the frequency band of the sensor can be substantially broadened and the reflective coefficient can be kept reasonably small.
