    摘要： A position detecting sensor is configured by providing a dielectric member having flexibility between first conductors and second conductors and providing spacers for separating the first conductors or the second conductors from the dielectric member by a determined gap. When a pressing force is applied by an indicator (e.g., a finger or a pen) on the position detecting sensor, the first conductor and the second conductor come to abut each other, with the dielectric member interposed therebetween. Further, an abutting area (contact area) between the dielectric member and the conductor changes (e.g., increases) according to the pressing force applied by the indicator. Thus, capacitance of the capacitor formed between the first conductor and the second conductor is largely changed, to allow detection of a position indicated by the indicator as well as the pressing force applied at the indicated position with high sensitivity and high accuracy.

    摘要： Systems, devices, and methods for determining stress in a target (110,210,410) are provided. The systems, devices, and methods facilitate detecting stress in the target (110,210,410) using a sensor assembly (402). Using a sensor, taw stress signals, which can correspond to stress in the target (110,210,410), can be generated by detecting a magnetic flux (140,440) that travels through the target (110,210,410). The raw stress signals (260) can be sensitive to a gap between the sensor and the target (110,210,410). A proximity sensor (224,324,424,524) element can be used to determine the size of the gap by generating an electric field between itself and the target (110,210,410). If the size of the gap changes, the strength of the electric field can change. Using a voltage of the proximity sensor (224,324,424,524) element, a corresponding gap signal (258) can be generated. The gap signal (258) can be used to correct the raw stress signals (260), thereby creating corrected stress signals (262), which can correspond to stress values within the target (110,210,410).

    摘要： An arrangement (2) to calibrate a capacitive sensor interface (1) comprises a capacitive sensor (10) having a capacitance (cmem, cmemsp, cmemsm) and a charge storing circuit (20) having a changeable capacitance (cdum, cdump, cdumm). A test circuit (30) applies a test signal (vtst) to the capacitive sensor (10) and the charge storing circuit (20). An amplifier circuit (40) has a first input connection (E40a) coupled to the capacitive sensor (10) and a second input connection (E40b) coupled to the charge storing circuit (20). The amplifier circuit (40) provides an output signal (Vout) in dependence on a first input signal (ΔVerr1) applied to the first input connection (E40a) and a second input signal (ΔVerr2) applied to the second input connection (E40b). A control circuit (60) is configured to trim the capacitance (cdum, cdump, cdumm) of the charge storing circuit (20) such that the level of the output signal (Vout) tends to the level of zero.

    摘要： A method of interfacing a LC sensor (10) with a control unit (20) is described. Specifically, the control unit comprises a first (202) and a second (204) contact, wherein the LC sensor (10) is connected between the first (202) and the second (204) contact, and wherein a capacitor (C1) is connected between the first contact (202) and a ground (GND). In particular, in order to start the oscillation of the LC sensor, the method comprising the steps of: - during a first phase, connecting the first contact (202) to a supply voltage (VDD) and placing the second contact (204) in a high impedance state, such that the capacitor (C1) is charged through the supply voltage (VDD); - during a second phase (2004), placing the first contact (202) in a high impedance state and connecting the second contact (204) to the ground (GND), such that the capacitor (C1) transfers charge towards the LC sensor (10); and - during a third phase (2006), placing the first contact (202) and the second contact (204) in a high impedance state, such that the LC sensor (10) is able to oscillate.
