Calibrating unweighting system for user on treadmill
A recently granted patent (Publication Number: US11957954B2) outlines a method for calibrating an unweighting system for a user. The method involves coupling the user to the system, unweighting the user to various levels while walking on a treadmill within a chamber, obtaining electronic signals from load cells at each unweighting level, and generating a user-specific calibration curve based on these signals. The calibration curve is then used to control the operation of the unweighting system during sessions for the user, ensuring precise unweighting levels tailored to individual users.
Specific details of the method include ensuring the weight of the user obtained during the initial unweighting condition closely matches external weight measurements, incrementally increasing unweighting levels, and utilizing a piecewise linear operation for generating the calibration curve. The patent also covers variations in the method, such as using additional load cells, different unweighting systems (differential air pressure or mechanical), and specific pressure levels for calibration. The method aims to provide a precise and personalized calibration process for unweighting systems, enhancing the effectiveness and safety of unweighting sessions for users.
