Abstract: A procedure for calibrating walking and/or running measurements in an exercise-related apparatus are provided. As a result of a user running and walking a given distance which may be the same or different for running and walking, respective running and walking motion metrics are obtained during a calibration phase. A relation between the obtained running and walking motion metrics are then used to compute a calibration value applied to calibrate one of running and walking measurements during an exercise.

Abstract: The invention relates to a wrist device and to a method of determining movement information. The method comprises measuring acceleration from a movement of a wrist device worn by a user during the user's stepping; and determining movement pulses associated with a lateral movement generated by the user's stepping by using said acceleration.

Abstract: A method and arrangement for blood pressure measurement are disclosed. In the method, a variable, compressive, acting pressure is applied to a compression, such as a person's extremity, by a pressure generator, and simultaneously, the effect of the variable acting pressure on the extremity is measured at a second point, the second point being farther from the heart than the compression point. The method determines diastolic and systolic pressure. The measured value of the variable acting pressure acting on the compression point is transferred to an interpreting unit, which also receives a pressure pulse generated by the heart. The pressure pulse is measured by a sensor at the second point for determining the effect of the variable acting pressure on the extremity. Further, diastolic pressure is determined int he interpreting unit based on the variable acting pressure, as the pressure when the interpreting unit detects a change in a trend of a characteristic of the pressure pulse indicative of magnitude.

Abstract: The invention relates to a method and arrangement for blood pressure measurement. In the method, a variable compressive acting pressure is applied to a measuring point, such as a person's extremity at a compression point by a pressure generator, and at the same time the effect of the variable pressure on the artery is measured at a second point, the second point being located farther away from the heart, i.e. closer to the end point of peripheral circulation than the compression point to which the pressure is applied. In the method diastolic pressure (PDIAS) and/or systolic pressure (PSYS) is determined as a result of an actual measurement.

Abstract: The invention relates to a method and arrangement for measuring venous pressure. The measurement is made non-invasively by applying a variable compressive acting pressure to a measuring point, such as a person's extremity, at a compression point by a pressure generator, and at the same time the effect of the variable pressure on the circulation is measured at a second point located farther away from the heart, i e. closer to the end point of peripheral circulation than the compression point to which pressure is applied. The measured value of the acting pressure is transferred to an interpreting unit to which is also applied a pressure pulse caused by the heart and measured at said second point by a sensor to measure the effect of the variable acting pressure.
