摘要： A method for evaluating the capacitance (C
s ) of a sensor electrode of a proximity sensor. First, the sensor electrode is charged with a charge voltage (U
o ) by coupling of the sensor electrode. At the same time, a compensation capacitance (C
K ) is charged by coupling in the compensation capacitance between a reference voltage (U
REF ) and ground. Then, the sensor electrode and the compensation capacitance (C
K ) are decoupled from voltage sources, wherein a state of charge of the sensor electrode and of the compensation capacitance is maintained. The sensor electrode is coupled to the compensation capacitance (C
K ) and charge balancing is performed. Now, the sensor electrode is decoupled from the compensation capacitance (C
K ), wherein the charge of the compensation capacitance which is present as a result of the charge balancing is maintained and the compensation capacitance (C
K )is coupled to an evaluation network in order to effect a current flow from the compensation capacitance through the evaluation network. The charge of a hold capacitance (C
H ) in the evaluation network is reversed by means of a charge-reversal current which is dependent on the current flow of the compensation capacitance, and the charge of the hold capacitance is evaluated after one or more such cycles.

摘要： Embodiments include capacitive touch sensors and methods for configuring capacitive touch sensors. A capacitive touch sensor embodiment includes an analog-to-digital converter (208) (ADC) and a controller (202). The ADC receives an analog voltage signal (252) from an electrode (106), and samples the analog voltage signal to produce a plurality of digital values (256). The controller performs a first charging process (504) by supplying the electrode with a first charging current for a first charging interval, and the controller determines (508), based on the digital values, whether a first electrode voltage value meets a criteria. If not, the controller performs a configuration process (524) that results in setting a second charging current and a second charging interval for the electrode which, in response to performing a second charging process, results in a second electrode voltage value that meets the criteria.

摘要： A proximity sensor interface device (PSID) for determining if a proximity sensor is in an acceptable position with respect to a target device is described. The PSID includes a frequency generator, a processing device, a memory associated with the processing device, a display, and an RC circuit. The processing device is programmed to route a signal generated by the frequency generator through the proximity sensor and the RC circuit for a prescribed period of time and the processing device is programmed to measure a discharge time of the RC circuit. The processing device is further programmed to cause the display to provide an indication of whether the relative position of the proximity sensor and the target device are within prescribed tolerances, based on the discharge time.

摘要： A capacitive touch panel can select a way of voltage control with a high degree of detection accuracy according to operating environment. In response to approach of an input unit, the stray capacitance of the sensing electrode the input unit approached increases. Accordingly, charge and discharge of the stray capacitances of a plurality of sensing electrodes are controlled, and a sensing electrode the potential change of which is made slow by the increase in stray capacitance and resultant increase in time constant is detected as a sensing electrode the input unit approached. The stray capacitance of a sensing electrode can selectively be controlled either by the charge control or by the discharge control, and optimum one of the controls is selected according to operating environment.
