Abstract: A device (1) is described for positioning electrodes on a user's scalp. It comprises a housing (3), for example a headpiece of a headphones device, which can be put around a user's head. An elastic element (11) and a plurality of electrodes are positioned, so that once the housing (3) is put around the user's head, the elastic element (11) at least partly follows the curvature of the user's head. The stress in the elastic element (11) due to stretching thereof caused by putting the housing around the user's head causes the elastic element (11) to exert pressure on at least some of the plurality of electrodes towards the scalp. Hereby, effective contact of the plurality of electrodes to the scalp is facilitated.

Abstract: A capacitive proximity device for sensing a presence and/or absence of an object in the proximity of an electronic device includes an emission electrode capacitively coupled to a receiver electrode, an oscillator for generating an emission-signal being an alternating electric field between the emission electrode and the receiving electrode, and a sensing circuit connected to the receiving electrode. The sensing circuit receives a measured-signal from the receiver electrode and includes a first synchronous detection circuit together with a low-pass filter for generating an output-signal being proportional to a distance between the object and the electronic device. The sensing circuit further includes a noise-suppresser for reducing noise from the measured-signal before entering the first synchronous detection circuit.
