摘要： An assembly and a method for determining a change in capacitance in a cable, such as a change caused by a deformation of the cable. The deformation may be caused by a deforming element attached to the cable and slideable along the cable. The deforming element may be adapted to be compressed by a user and convert the compression force into a compression of the cable so as to cause the capacitance change. The assembly may form part of a headset and the deformation may be used to control a media player or mobile telephone used with the headset.

摘要： A capacitive transducer (1) comprises a polymer film (2) having a first surface and a second surface, a first electrically conductive layer (3) arranged on the first surface of the polymer film (2), and a second electrically conductive layer (3) arranged on the second surface of the polymer film (2). The polymer film (2) is at least partly made from a material having a molecular weight which is at least 21,000 g/mol. The inventors have surprisingly found that silicone polymer materials with high molecular weights, such as liquid silicone rubbers (LSR) or high temperature vulcanizing (HTV) elastomers, have high electrical breakdown strengths, even though technical data sheets from manufacturers state almost identical electrical breakdown strengths similar to that of RTV-2 elastomers. Using such materials in capacitive transducers allows high electrical fields to be applied to transducers without risking electrical breakdown, thereby increasing performance of transducers.

摘要： Sensors (32, 52, 72) for determining a gap between a conductive member (34, 54, 74) such as a blade in a gas turbine engine and a seal segment (31, 51) are known to use capacitive variants in order to create an electrical signal indicative of the gap width. Thermal disparities can create problems with regard to sensor aging and accuracy. By creating a sensor incorporating a metal rod (33, 53, 74) typically integrally formed or associated with the seal segment (31, 51) and coupled through inductive coupling loops (35, 36; 55, 56; 75) it is possible to create a tuned circuit with a Q value which is more stable and therefore acceptable with regard to producing more accurate results at elevated temperatures with less problems with regard to thermal disparities.

摘要： A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts moveable relative to each other provided with electrodes that together form condensers, whose magnitudes are variable and depend on the relative position as specified by a sinusoidal relationship between the two parts. The first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period. The electrodes in the first part are fed with n alternating voltages whereby the time displacements of the alternating voltages relative to each other are t 0 n , , where t0 is the length of the period of the alternating voltage. The electrode of the second mobile part captures a signal composed of one or several of the alternating voltages and the amplitude composition of the signal depends on the relative position between the two parts.

摘要： A position indicator includes a tubular core member, a first coil, a second coil, a substantially bar-like rod, a pen-pressure detecting element, at least one capacitor, and a switch. The tubular core member is formed by a substantially bar-like first magnetic core and a substantially bar-like second magnetic core, which are combined in a transversal direction thereof to form a through-hole therebetween. At least one of the first and second magnetic cores may include a recessed portion formed therein extending in the axial direction thereof. The first coil is wound around the tubular core member, and the second coil is wound around the second magnetic core. The rod is inserted into the through-hole of the tubular core member. The pen-pressure detecting element detects a pressure applied to an end of the rod (i.e., the pen tip). The capacitor is connected to the first coil to form a resonant circuit. The switch controls “on” and “off” states of the second coil for the purpose of calculating a rotation angle of the position indicator about its axis.
