Abstract: A method for detecting an amount of grains within a container of a rotating grinding member is described, said method comprising the steps of: supplying (FORP1) a first driving torque to the rotating grinding member during a first interval (T1) of a grinding cycle (CM); —having (CTM1OO) a first value indicative of a period of rotation of said member at the first driving torque; supplying (RP2) the rotating grinding member, during a second interval (T2) of said cycle, with a second driving torque lower than the first driving torque; —measuring (CTM50) a second value indicative of the relative period of rotation of said member at the second driving torque, processing (CDTR, CNFR) the first and second values in order to generate information (ALR) indicative of the amount of grains being within the container.

Abstract: A system comprises a display (1) with a substrate (16) and a carrier (2). The display (1) comprises pixels (11) and display conductors (12) which supply display signals (DS) to the pixels (11). The carrier (2) comprises carrier conductors (20) for carrying input signals (IS). The display conductors (12) and the carrier conductors (20) are positioned with respect to each other to obtain capacitors (C) between corresponding ones of the display conductors (12) and the carrier conductors (20) to capacitively transfer the input signals (IS) on the carrier conductors (20) to the display conductors (12).
