ABSTRACT
The sensor is an important part of REMPARK since it is in charge of capturing relevant inertial data from the patient’s movement pattern. The location of the sensor is the left side of the waist and its operation is autonomous and done in real-time. A microcontroller is in the nucleus of the sensor, being responsible for the real-time and local execution of the developed algorithms on the acquired data. The theoretical approximation of the required microcontroller computation time is difficult to be done, and for this reason a measurement strategy was organized at the laboratory. Frequency also imposes specific time restrictions on the online implementation of the algorithms, which finally creates important constraints on the specific microcontroller to be used for the implementation. Going along the different developed algorithms, it is necessary to evaluate the necessary sampling frequency to be applied.
