Accuracy in detection of electrocardiographic (ECG) heart beats can be vastly improved with the aid of blood pressure (BP) monitoring. Cross validation between ECG and BP signals is used to identify the part of signals not contaminated by large, high frequency noises, where we can extract accurately the delay between the QRS peaks and BP peaks (defined in the “Methods” section). The delay is used...
An integrated navigation method for land vehicle is researched in this paper, which is based on SINS, geomagnetic matching and barometric altimeter. Horizontal position output from geomagnetic matching, altitude output from barometric altimeter and corresponding outputs from SINS are taken to construct the measurement. Fuzzy self-adaptive kalman filtering algorithm is adopted in the design of integrated...
The absolute attitude error of chaser vehicle is always neglected in observation equation of space relative navigation filter when chaser satellite on-board radar using as the measurement sensor. But the attitude error could affect relative navigation filter precision in fact. The new observation equation, which contains the absolute attitude error of chaser vehicle, is constructed. And the plan,...
