A multipoint contact detection device includes at least two capacitive or inductive sensitive structures associated with respective primary detection zones of a surface that a person is likely to contact. The sensitive structures are positioned with a separation that is small enough between them to define at least one intermediate detection zone that the person is likely to contact while exerting a capacitive or inductive disturbance on the adjacent sensitive structures. The device also includes a processing circuit configured to detect, for each sensitive structure, a disturbance induced by the person coming into proximity or into contact and locating the region or regions of the surface with which the person comes into contact relative to the primary detection zones and the one or more intermediate detection zones.

An automatic liquid density measurement device includes a receptacle configured to contain the liquid, a float configured to be submerged in the liquid when it is contained in the receptacle, and an electronic system. The electronic system includes a first electromagnetic sensor configured to make a reference measurement relative to the electrical properties of the liquid, a second electromagnetic sensor configured to make a measurement of the volume of the liquid displaced when the float is submerged in the liquid, and an electronic circuit coupled with said first and second electromagnetic sensors to determine the density of the liquid based on the measurement of the physical properties of the liquid and the measurement of the volume of the liquid displaced.

The bottle has a neck sealed by a stopper. The safeguarding device () comprises a first and a second part (), the first part () being adapted to be integrated in the stopper () and the two parts () being joined in translation while allowing a limited relative movement of one part with respect to the other when a traction force is applied to the safeguarding device () in order to remove said stopper () from the neck. According to the invention, the safeguarding device comprises an electrical component () disposed so that at least one electrical characteristic of said component is modified during the relative movement of the two parts ().
