Abstract: The system comprises a monitoring device, one acquisition unit and respective method for monitoring and registering the position of an individual. This disclosure is intended for the following applications: 1) prevention or assistance in the treatment of pressure ulcers (or decubitus ulcers), common in immobile patients (2) or wheelchairs users, 3) monitoring of patients suffering from dementia (which makes them do some actions (for instance: getting up from a chair) without being aware of them, and that can suffer serious accidents due to that), 4) fall detection and 5) involuntary body movements (e.g. epileptic attack). The monitoring device comprises an inertial system, with 3 or more accelerometers; a directional system, with 3 or more magnetometers; a communication module; and a processor module to obtain and communicate the inclination and direction of the device, when coupled to an individual.

Abstract: The disclosed subject matter relates to a portable and autonomous device and corresponding method for the measurement, recording and calculation of dynamic parameters of the pedestrian locomotion of its bearer. The method hereby disclosed allows determining the distance effectively travelled, the velocity of displacement and the pressures exerted on the contact surface of the lower limb with the ground, during the pedestrian locomotion, according to its different phases. Through sensors strategically placed, accelerations, angular velocities and pressures are measured and recorded on the control unit. The device disclosed includes a processing unit that implements the method disclosed and a communication unit to transfer to an external unit the calculated parameters. The disclosed invention can be used in applications that involve monitoring parameters of the locomotion activity or daily ambulation of its bearer, in the areas of health and sports or in any physical and occupational activities.
