A user may provide finger press input to a surface such as a touch sensitive input surface. The input surface may be formed from a two-dimensional touch sensor overlapping a display of an electronic device. The electronic device and an associated device such as a finger-mounted device may form a system for gathering the finger press input from the user. A sensor may be used in monitoring when the finger-mounted device and a user's finger in the device approach the input surface of the electronic device. In response to detection of the finger near the input surface, actuators in the finger-mounted device may squeeze the finger inwardly to cause a finger pad on the finger to protrude outwardly towards the input surface, thereby softening impact between the finger and the input surface. The electronic device may also have an array of components to repel the finger-mounted device.

A photoelectric sensor is configured to detect an object by reception of light from a light projecting unit in a light receiving unit. The photoelectric sensor differentiates a sampled light reception amount with respect to time to calculate a variation in the light reception amount per unit time, and sets as a threshold a light reception amount corresponding to an extreme value of the variation in the light reception amount. In this manner, the threshold is set with the variation in the light reception amount per unit time taken into account, thereby enhancing the accuracy in detection of the object by comparison between the light reception amount and the threshold, to allow minimization of jitter of a detection signal from the photoelectric sensor to a programmable logic controller.

The contact sensor (S) is decoupled from the driver circuit (T) by means of the decoupling unit (E) in such a manner that contact of the sensor electrode (S) by a user can be detected during operation of the radiation-emitting component (D).

An earphone including a proximity sensor, an acceleration sensor, and a signal analysis device. The signal analysis device identifies an approaching movement of the earphone to an object using the proximity sensor signal. The signal analysis device ascertains whether the approaching movement is a movement of the earphone to an ear of the user. By filtering the acceleration sensor signal, the signal analysis device generates a high-pass filtered acceleration signal and a low-pass filtered acceleration signal. The signal analysis device determines an end time of the approaching movement based on a stabilization of the acceleration, using the low-pass filtered acceleration signal. The signal analysis device confirms that the approaching movement is a movement of the earphone to an ear of the user based on changes in the high-pass filtered acceleration signal after the ascertained end time of the approaching movement.

The invention relates to a switching control arrangement, in particular for a motor vehicle, having a movable actuating surface. The actuating surface interacts with a displacement means in such a way that the actuating surface can be moved substantially linearly, over at least one distance, out of an initial position and into an actuating position. The displacement means has at least one elastic element arranged so as to be clamped in place. The actuating position can be designed as a switching position, such that the actuating surface, when in the switching position, has a switching effect on a switching element, a sensor, or the like. The elastic element is designed as a planar element with a small thickness in the form of a membrane, such that it is possible for the elastic element to be elastically deflected substantially perpendicularly to the surface of the membrane.
