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.

Weighing device with a wheatstone bridge assembly and method

Electronic scale including four feet, four strain gauges, an electronic control unit and a display, where the gauges are combined in pairs in first and second Wheatstone bridge type circuits, where a first intermediate-point of the bridge is selectively connected via a switch to an intermediate voltage source and where the first and second outputs of the amplifiers are summed by the electronic control unit in order to deduce therefrom a weight for an object present on the device, with indication for the user of off-center condition on the scale. Weighing method implemented in such a scale.

Weighing device and method with off-center indication

Weighing device of the digital bathroom scale type, comprising four feet each having a strain gauge, four conducting portions on the top surface, and one electronic control unit, the electronic unit being configured to measure first signals indicative of periodic variations in weight and second signals indicative of periodic variations in impedance caused by the heartbeats of the user, the electronic unit being configured to determine the heart rate of the user from the first and second signals. Method for determining the heart rate of the user from the first and second signals.
