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.

摘要： A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts that can move relative to each other provided with electrodes that together form condensers, the magnitudes of which are variable and depend on the relative position as specified by a sinusoidal relationship (xc) between the two parts that can move relative to each other, whereby the first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period, and that the electrodes in the first part are fed with n alternating voltages whereby the time displacements of the said alternating voltages relative to each other are (Fig I), where t0 is the length of the period of n the said alternating voltage, whereby the electrode of the second mobile part captures in a capacitive manner a signal that is composed of one or several of the said alternating voltages and where the amplitude composition of the composite signal depends on the relative position (x) between the two parts. All n signal contributions to the said amplitude composite are measured and stored separately for each one of the n samplings.

摘要： A capacitive detection device, a method and a pressure detection system are provided. The capacitive detection device (10) includes a differential amplifier (14), a first capacitor (15), a second capacitor (16), a charging module (12), a control module (11) and a calculation module (13), where the differential amplifier (14) includes a first input terminal, a second input terminal, a first output terminal and a second output terminal. The charging module (12) is controlled by the control module (11) to charge two capacitors to be detected, then an amount of charge of the capacitors to be detected is transferred to the first capacitor (15) and the second capacitor (16), and a signal is amplified through the differential amplifier (14) and the amplified signal is output to the calculation module (13), so that a capacitance difference of different capacitors may be obtained through a voltage at an output terminal of the differential amplifier (14), a supply voltage of the charging module (12), a capacitance of the first capacitor (15) and a capacitance of the second capacitor (16).

摘要： A sensor suitable for sensing the relative movement between at least part of the sensor and one or more target objects. The sensor including at least one polarised or at least partially polarised dielectric material and at least one electrode. The interaction of the one or more target objects with the static electric field of the dielectric material produces a signal or voltage change in the electrode.

摘要： A displacement sensor for sensing a change in separation between a first element and a second element along a displacement direction. The sensor comprises a reference electrode mounted to the second element in the form of a conductive trace on a surface of the second element facing the first element. A deformable electrode, e.g. a conductive elastomeric material, is arranged between the first element and the second element so as to overlie the reference electrode. The deformable electrode has a contact surface facing the reference electrode and insulated therefrom. At least part of the contact surface is inclined relative to an opposing surface of the reference electrode such that when the deformable electrode is compressed along the displacement direction there is a reduction in volume between the contact surface and the opposing surface of the reference electrode, thereby changing the capacitive coupling between them. The sensor further comprises a controller element configured to measure a characteristic of the capacitive coupling between the reference electrode and the deformable electrode and to determine if a change in separation between the first element and the second element has occurred be determining if there is a change in the characteristic of capacitive coupling between the reference electrode and the deformable electrode.
