Abstract: The invention relates to a heart rate monitor electrode (1). The electrode comprises a mounting (2), conductive points (23) and a plate of absorbent material (4). The free end (24) of at least some of the conductive points (23) is flush with the contact surface of the plate of absorbent material (4) or stands proud from same when the plate of absorbent material (4) is in at least partial compressed form and releases at least a portion of the liquid it contains. According to other aspects, the invention relates to a device comprising at least one such electrode (1) and a method for measuring heart rate by means of the same.

Abstract: A method for controlling the machining of a part by a portable automatic machining apparatus. A machining tool configured to machine the part under the action of a pressurized fluid feeding the apparatus, and following a machining cycle, comprising a number of phases and a machining support equipment item. The machining support equipment item cooperates with the machining tool during the machining of the part. The method comprises the steps of measuring the pressure of the fluid at the outlet of the apparatus, analyzing the measured pressure to detect at least one phase of the cycle of machining of the part by the machining tool from the duly measured pressure, and controlling the machining support equipment item as a function of the phase of the machining cycle which has been detected.
