Abstract: Heart sound signal; LabVIEW2009; Navigation; Remote Monitoring. Abstract. Heart sound signal contains much information about physiology and pathology of heart, which has the irreplaceable advantages over ECG and ultrasonic electrocardiogram. Therefore, the effective diagnosis of PCG signal can improve the level of diagnosis and treatment of cardiovascular diseases. This paper mainly introduces an intelligent system about PCG signal monitor and real-time analysis. By utilized the LabVIEW2009 virtual instrument developing platform, a virtual health monitor for common family is set up. It includes some useful functions, such as preliminary PCG monitoring, automatic diagnosis and remote monitoring, which endow it with a potential value.

Abstract: The problem of computer control algorithm for the singular Von Neumann input-output model is researched. A kind of new mathematic method is applied to study the singular systems without converting them into general systems. A kind of stability condition under which the singular input-output model is admissible is proved with the form of linear matrix inequality. Based on this, a new state feedback stability criterion is established. Then the formula of a desired state feedback controller is derived.

Abstract: Due to the high risk of heart disease，expensive monitoring costs, the unequal distribution of medical resources, the development of home-based health monitoring systems is worth addressing, the construction of a low-cost home-based electrocardiography (ECG) monitor is introduced. It can make related judgments on the health status of the check-up people according to the ECG signal. By utilized the LabVIEW2009 virtual instrument developing platform, a virtual health monitor for common family is set up. It includes some useful functions, such as preliminary ECG monitoring, automatic diagnosis, navigation and remote monitoring, which endow it with a potential value.
