Abstract: A navigation and positioning system for an underwater glider includes a micro-electro-mechanical system inertial measurement unit, a global positioning system receiving module, a triaxial magnetometer, a Doppler velocimeter, and an integrated navigation hardware processing system. If a navigation and positioning error is too large, the underwater glider stops working in real time and switches from the underwater working state to the up floating error correction state; and when velocity and location errors of a GPS/INS integrated navigation system are smaller than specified thresholds, the underwater glider switches from the up floating error correction state to the underwater working state and continues to work. An Hoc Kalman filter algorithm based on an adaptive multiple fading factor is established to ensure robustness and adaptability of navigation and positioning of a glider.

Abstract: The present invention discloses a method for noninvasive imaging of cardiac electrophysiological based on low rank and sparse constraints. This method decomposes the spatio-temporal distribution of endocardial and epicardial potentials into a low-rank matrix representing smooth potential components and a sparse matrix representing the details of potential salience according to the prior condition of spatio-temporal correlation of the endocardial and epicardial potential distribution of the heart. By introducing low rank and sparse constraints, the solution of the ill-conditioned inverse problem of ECG is constrained to the unique optimal solution. The invention combines the individualized three-dimensional heart model of the subject to obtain a three-dimensional dynamic distribution image of the cardiac endocardial and epicardial potential of the subject, which has important practical application value.
