A weighing device of the electronic bathroom scale type, includes four feet, each fitted with a load cell, each load cell including two resistors combined in a Wheatstone bridge type of assembly to define a first axis of symmetry and a second axis of symmetry, the assembly further including at least one auxiliary circuit configured to selectively short-circuit two resistors belonging to the same foot or to two neighboring feet in the bathroom scale, the first auxiliary circuit being symmetrical relative to the first axis or the second axis, the assembly being controlled by an electronic control unit to estimate a weight and to estimate an offset of a user on the bathroom scale.

A microfluidic apparatus for delivering droplets of a first fluid to droplets of a second fluid, comprising a main channel, with a carrier fluid carrying droplets of the second fluid, an auxiliary channel, fluidly coupled to the main channel at a first intersection via a first orifice with a first fluid interface, and at a second intersection downstream to the first intersection via a second orifice with a second fluid interface, wherein a flow of the carrier fluid induces a difference of pressure between the first and second orifice generating a balance condition such that a meniscus of the second fluid interface is maintained in the auxiliary channel, at the vicinity of the second orifice, wherein a balance deviation triggers a release of a volume of the first fluid from the second fluid interface into the main channel.

A cuff-type monitoring device, for collecting cardiovascular data relating to an individual user, comprising a control unit housing and a cuff assembly coupled or attached to the control unit housing, the cuff assembly comprising an inner layer, an inflatable bladder, a cuff holder, forming an structural resilient armature of the cuff assembly, an intermediate sheet, an outer band, wherein the cuff assembly is configured, in use, to surround a upper limb of the individual, with the inner layer in contact with the upper limb, wherein control unit housing comprises at least a pump configured to inflate the inflatable bladder, wherein the intermediate sheet is made in an inextensible, i.e. non-stretchable, fabric and there is provided a border joint or seam at least on three sides on a peripheral border of the inflatable bladder, the border joint joining and securing together the inner layer, the inflatable bladder, the intermediate sheet, and the an outer band.
