—In this paper we derive a reduced model, that is, a model in terms of independent generalized coordinates, for the equations of motion of closed-chain mechanisms. We highlight the fact that the model has two special characteristics which make it different from models of open-chain mechanisms. First, it is defined locally in the generalized coordinates. We(More)
Smart clothes increase the efficiency of long-term non-invasive monitoring systems by facilitating the placement of sensors and increasing the number of measurement locations. Since the sensors are either garment-integrated or embedded in an unobtrusive way in the garment, the impact on the subject's comfort is minimized. However, the main challenge of(More)
Elevated Blood Pressure (BP) is a human‐specific illness affecting a quarter of the worldwide population. Clinically known as hypertension, elevated BP is considered the major risk factor for cardiovascular disease: the most common cause of death in developed countries. Detecting, treating and controlling hypertension are major goals of modern medicine. For(More)
—This paper presents an analytical model for the force and torque developed by a reaction sphere actuator for satellite attitude control. The reaction sphere is an innovative momentum exchange device consisting of a magnetic bearings spherical rotor that can be electronically accelerated in any direction making all the three axes of stabilized spacecrafts(More)
Pulse-wave velocity (PWV) is considered as the gold-standard method to assess arterial stiffness, an independent predictor of cardiovascular morbidity and mortality. Current available devices that measure PWV need to be operated by skilled medical staff, thus, reducing the potential use of PWV in the ambulatory setting. In this paper, we present a new(More)
This paper presents the development of an analytical model for the force and torque developed by a Reaction Sphere for satellite attitude control. The Reaction Sphere is a magnetic bearings spherical motor whose rotation axis can be electronically controlled. The actuator is composed of an 8-pole permanent magnet spherical rotor and a 20-pole stator. Force(More)
— After system modeling, controller synthesis and closed-loop simulation, the control engineer has still to implement the controller. In many applications, the controller must be realized with a fixed-point digital processor. The translation of the synthesized controller to its fixed-point realization is intrinsically difficult, because there are an(More)
Cooperative sensors are an emerging technology consisting of autonomous sensor units working in concert to measure physiological signals requiring distant sensing points, such as biopotential (e.g., ECG) or bioimpedance (e.g., EIT). Their advantage with respect to the state-of-the-art technology is that they do not require shielded and even insulated cables(More)
