    摘要: Embodiments are disclosed for a biomechanical trigger for improved responsiveness in grade estimation. In some embodiments, a method comprises: A method comprises: obtaining, from a wearable device worn by a user, cadence data, speed data and elevation data; determining a grade of a surface on which the user is traveling based on a ratio of a change in elevation based on the elevation data and a change in speed data; determining that the grade satisfies a first condition indicative of a horizontal speed compensation by the user at a grade onset; determining that the grade satisfies a second condition indicative of a rapid elevation increase or decrease at a grade onset; and confirming that the grade is a valid estimate based on either the first condition or the second condition being satisfied.

    摘要: A device for warning about the absence of belaying of a climber includes an enclosure intended to be fastened to a harness. A pressure sensor is designed to measure a barometric pressure. A detector, intended to be fastened to a link, is configured to detect a movement of the link within a range of positive inclines with respect to a horizontal reference plane. The detector is also configured to output a detection signal comprising a first state, indicating that the link is within the range of positive inclines, and a second state, indicating that the link is outside the range of positive inclines. A microprocessor is configured to compute a variation in the barometric pressure measured by the pressure sensor, and send a warning signal as soon as the variation in the barometric pressure exceeds a predetermined threshold and the detection signal is in the second state.
