摘要： A circuit for operating a capacitive sensor configured to be operated alternately in a first mode over a first time interval and in a second mode over a second time interval. The circuit includes a GM stage configured to receive a sensor voltage of the capacitive sensor at a first input contact and convert the sensor voltage into a sensor current to charge a first boxing capacitor with the sensor current in the second time interval, an integrator that is configured to, in the second interval, integrate a voltage applied across the first boxing capacitor over its time curve and output a resulting output voltage at a first output, and a hold circuit configured to tap the output voltage of the integrator in the second interval and hold it as a hold voltage.

摘要： An input check device includes a coordinate detection part configured to detect coordinates of a touch operation a user performs on an operating surface when operating an operating part through the operating surface; a pressing force detection part configured to detect a pressing force of the touch operation; and an identifying part configured to determine whether the operating part is ON or OFF based on the pressing force detected in the pressing force detection part, and, after determining that the operating part is switched from ON mode to OFF mode, the identifying part detects a minimum value of the pressing force; and the identifying part determines that the operating part is switched from OFF to ON when, following the detection of the minimum value, the pressing force surpasses a predetermined threshold that is set based on the minimum value and that is greater than the minimum value.

摘要： An input mechanism, such as a crown, detects amounts of applied force. In various examples, an assembly including an input mechanism has an enclosure; a stem coupled to the enclosure such that the stem is rotatable, translatable, and transversely moveable with respect to the enclosure; a sensor, coupled between the stem and the housing, to which force is transferred when the stem moves with respect to the housing; and a processing unit coupled to the sensor. The processing unit is operable to determine a measurement of the force, based on a signal from the sensor.

摘要： To provide an input operation device capable of detecting, using a simple configuration, a first operation of touching an operation surface with an operation body and a second operation of pressing the operation surface with the operation body.
An input operation device 11 includes a detection value changing part 31, which changes a detection value of a capacitive sensor 12, and a supporting part 41, which supports a touch sensor part 21 in a state in which the detection value changing part 31 and the touch sensor part 21 are separated from each other. The detection value changing part 31 is arranged on a back surface 24 side opposite to the operation surface 22 of the touch sensor part 21, and changes the detection value depending on contact with the detection part 23. The supporting part 41 includes an elastically shape-changeable part 42, which elastically changes shape so as to bring the detection part 23 into contact with the detection value changing part 31 in response to pressing of the operation surface 22. The capacitive sensor 12 of the input operation device 11 generates a first detection value indicating a first operation of touching the operation surface 22 and a second detection value indicating a second operation of pressing the operation surface 22 toward the detection value changing part 31.

摘要： A system may include a sensor configured to output a sensor signal indicative of a distance between the sensor and a mechanical member associated with the sensor, a measurement circuit communicatively coupled to the sensor and configured to determine a physical force interaction with the mechanical member based on the sensor signal, and a compensator configured to monitor the sensor signal and to apply a compensation factor to the sensor signal to compensate for changes to properties of the sensor based on at least one of changes in a distance between the sensor and the mechanical member and changes in a temperature associated with the sensor.

摘要： A method for detecting the intention of a user to lock or unlock a motor-vehicle door with a detection device integrated into a handle. The method includes continuously measuring the resonant frequency of the detection device and successively comparing the measured resonant frequency to a first threshold representative of the approach of the user and to a second threshold, higher than the first threshold, representative of the contact of the user, the intention of the user to lock or unlock the door of the vehicle being validated only if a duration between the passage of the resonant frequency below the first threshold and the passage of the resonant frequency above the second threshold is shorter than a preset duration. An associated detection device is also disclosed.

摘要： Sensor assemblies for electronic devices are described. According to some embodiments, the sensor assemblies include solid-state sensors, such as capacitive sensors, piezoelectric sensors or piezoresistive sensors. The sensor assemblies can include a number of features that provide a compact profile, making them well suited for integration into small spaces of electronic device enclosures. The sensor assemblies can also include features that isolate movement of various parts of the sensor assemblies, allowing for accurate detection of a sensing event. According to some embodiments, the sensor assemblies are coupled to haptic actuators, speaker, or both, which mimic the feel of a mechanical button and enhance a user's experience.

摘要： In a touch sensor unit, since a base portion is provided with a hard resin portion for holding a curved state of a sensor portion deformed in conformity to a curved shape of a door frame of a tail gate, even when the base portion is not fixed to the tail gate, it is possible to hold the curved state of the base portion. Therefore, after the curved base portion is fixed to the tail gate with a double-sided adhesive tape, even if the double-sided adhesive tape is degraded with age, a restoring force of the sensor portion does not remove the double-sided adhesive tape.
