Background Obtaining tachycardia electrocardiograms (ECGs) in patients with paroxysmal supraventricular tachycardia (PSVT) is often challenging. Sinus rhythm ECGs are of limited predictive value for PSVT types in patients without preexcitation. This

In this paper, we present a method for finding the enhanced heading and position of pedestrians by fusing the Zero velocity UPdaTe (ZUPT)-based pedestrian dead reckoning (PDR) and the kinematic constraints of the lower human body. ZUPT is a well know

In this study, the effect of acceleration matching according to sensor specifications in rapid transfer alignment is analysed. In general, the velocity and attitude information of the Master Inertial Navigation System (MINS) is used for transfer alig

In this paper, we propose a pedestrian dead reckoning (PDR) system that uses the velocity predicted by a foot kinematic constraint and ellipsoidal shoe modeling in the contact phase. Generally, a PDR system with foot-mounted inertial sensors often us

In this paper, we present a pedestrian dead reckoning (PDR) system with multiple virtual tracking for indoor navigation using a smartphone. In general, the heading error is one of the main factors causing positional errors in smartphone-based PDRs. T

This paper deals with inertial navigation system (INS) aided by a vertical gauge (VG) for unmanned vehicles in two different schemes, vertical channel damping (VCD) and Kalman filter (KF). As the altitude error of standalone INS goes to diverge quick

In this paper, step length models using an inertial sensor on pelvis are compared by experiment. Step length estimation is an important process of pedestrian dead reckoning (PDR). However, the step length is difficult to measure directly by an inerti
