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 sensor unit is configured to have an insulating case covering a mobile phone, a conductive substrate provided on the inner surface of the case, and a sensor electrode fixed on the surface of the conductive substrate. When a part of the human body of a user, such as a finger or a hand of the user, touches the surface of the case, a detection unit detects a change in capacitance provided between the human body and the conductive substrate. When it is determined that the user has touched the mobile phone, an activation signal is output and the operation mode of the mobile phone is set to a normal power mode in which power is automatically supplied. With this configuration, the operability of the mobile phone can be improved.

摘要： A variable capacitance unit is formed between one portion of a human body and an opposed electrode facing it through a casing of a robot toy (electronic device) when the one portion of the human body such as a hand or a finger approaches the surface of the casing of the robot. Since the capacitance of the variable capacitance unit varies according to the facing area and the facing distance of the one portion of the human body and the opposed electrode, it is possible to detect the one portion of the human body approaching or touching the robot toy by detecting this change. Since the opposed electrode forming the touch sensor can be provided within the casing, the touch sensor cannot be seen directly from the outside of the robot toy.

摘要： A touch sensor includes: a pulse signal generator for generating a pulse signal of which pulse width is calibrated in response to a control code; a pulse signal transmitter for transmitting the pulse signal when a touch object is out of contact with a touch pad and stopping transmitting the pulse signal when the touch object is in contact with the touch pad; a pulse signal detector for detecting the pulse signal transmitted through the pulse signal transmitter; and a controller recognizing a non-contact state and adjusting the control code to calibrate the pulse width of the pulse signal when the pulse signal detector detects the pulse signal. In the above-described configuration, the contact of the touch object with the touch pad can be sensed more precisely, and the occurrence of a malfunction in the touch sensor due to changed operating conditions can be prevented.

摘要： A capacitive sensor may be used as a proximity detector in an obstruction warning system for road vehicles, e.g. for use when the vehicle is reversing. A digital signal processor 11 sends a sine wave through a sensor RC circuit 1, 7. A sensor plate 3 acts as one plate of a sensor capacitor 1 and the obstruction 45 acts as the other plate 5. Changes in the distance between the car 43 and the obstruction 45 result in changes in the capacitance of the sensor capacitor 1, changing the amplitude and phase of the sine wave output by the sensor RC circuit 1, 7. A reference sine wave, generated by a reference signal circuit 17, 19, 21 is subtracted from the sensor output signal in a subtractor 15. The reference signal has a phase offset from the sensor signal so that the amplitude of the difference signal is highly sensitive to changes in phase of the sensor signal. An additional signal, substantially identical to the sensor signal, is coupled to the output of the sensor RC circuit by a coupling capacitor 41. This provides a path to ground for high frequency noise without disrupting the sensor signal.

摘要： An instruction inputting device detects input operations in the XY plane and in a rotational direction on a hemispherical input operation surface. Four detection electrodes insulated from each other are formed at 90° intervals around the Z axis of the hemisphere, on the surface of a spherical crown-shaped insulator. Surface areas of each of the detection electrodes decrease moving toward an apex P on the Z axis and moving in a circumferential direction away from the positions at which the 90° intervals are formed. As a result, the surface areas of the detection electrodes facing an object to be detected for causing the input operation differ depending on the positioning of the object, thereby causing differences in the floating capacitances of the detection electrodes which are sensed by a circuit portion of the device.
