摘要： A mobile device has a proximity sensor. A compensation value of the proximity sensor is determined. The compensation value is compared to a reference compensation value to determine validity of the compensation value. A capacitance of the proximity sensor is measured. A value of the capacitance of the proximity sensor is adjusted based on the compensation value. A coefficient defining a relationship between a capacitance of the proximity sensor and a temperature of the mobile device is calculated. A temperature sensor is coupled to the proximity sensor. The temperature of the mobile device is measured. A value of the capacitance of the proximity sensor is adjusted based on the coefficient and the temperature of the mobile device. The adjusted capacitance value is compared to a threshold capacitance value to determine proximity of an object to the mobile device. A radio frequency signal is adjusted by detecting proximity.

摘要： A proximity sensor, and a portable device equipped therewith, with at least two superposed sense electrodes, one partially screening the other. By reading the capacity first of one electrode, then of the other, while setting the potential of the counter-electrode either to ground or to guard, the sensor of the invention discriminates between a body part, or another electrically equivalent object, and water drops at closer distance.

摘要： A capacitive proximity detector for use in a connected portable device such as a telephone, laptop or tablet, in which the capacity seen by the sensor electrode is compared with four thresholds: a proximity threshold, set lower than the other, to generate a general proximity flag, and a body detection threshold set higher than the other arranged to generate a body detection flag that indicates that the object in proximity is a part of a human body. Two object detection thresholds in the region between the proximity threshold and the body threshold define a region in which the detector can decide whether the object in proximity is an inanimate object, based on the time variation of the capacity.

摘要： The invention relates to a capacitive sensor system, in particular for detecting the approach of objects and in particular also for gesture recognition. The problem of the present invention is to provide a capacitively operating sensor system, which can be implemented with low component complexity and thus low costs and space requirements and is also characterized by low power consumption, so as to operate with batteries having a low charge capacity and/or a long operating time. Said problem is solved according to the invention by a circuit configuration for generating an output signal correlating with an approximation process based on changes in the dielectric properties of the surroundings of a sensor electrode, having a sensor electrode which is adjacent to an observation area in at least some sections, a microcontroller circuit (μC) for output of an alternating voltage, a voltage divider circuit for achieving an adjustment of the level of the alternating voltage output by the microcontroller (μC), and a field effect transistor (FET) in the function of an impedance converter, wherein the field effect transistor is incorporated into the circuit configuration in such a way that the voltage output by the voltage divider circuit is present at the gate input thereof and at the same time at the sensor electrode (ES).

摘要： A self-capacitive touch sensing circuit including an operational amplifier, an internal capacitor, a first switch and a second switch is disclosed. A first input terminal and a second input terminal of operational amplifier are coupled to a capacitor and ground respectively and an output terminal of operational amplifier outputs an output voltage. The internal capacitor is coupled between the output terminal and first input terminal of operational amplifier. One terminal of first switch is coupled to a first external charging voltage and another terminal of first switch is coupled between the capacitor and the first input terminal. The first external charging voltage is higher than the second external charging voltage. The first switch and second switch are switched according to a specific order, so that the first external charging voltage or second external charging voltage will charge the capacitor.

摘要： A capacitive touch switch apparatus includes a touch electrode; a touch detection circuit that generates a capacitance signal indicative of a capacitance of the touch electrode in accordance with a touch to the touch electrode, and generates and outputs a touch detection signal indicative of presence or absence of the touch by comparing the capacitance signal with a predetermined threshold; and a threshold determination circuit that supplies a threshold determination signal for determining the threshold to the touch detection circuit. The threshold determination circuit supplies the threshold determination signal to the touch detection circuit so as to increase the threshold in accordance with a change of the touch detection signal from a first level indicative of absence of the touch to a second level indicative of presence of the touch.
