Abstract: A method to identify feature points associated with the heart valve movement, heart contraction or cardiac hemodynamics is revealed. The mechanocardiography (MCG) is a technology that makes use of vibrational waveforms acquired using at least one gravity sensor attached on one of the four heart valve auscultation sites on the body surface. The data of the electrocardiography (ECG) is recorded simultaneously with the MCG The feature points are identified by comparing P, R and T points of synchronized ECG with the MCG spectrum. By the time sequences and amplitudes of the feature points, the method provides additional clinical information of cardiac cycle abnormalities for diagnosis.

Abstract: A method for updating security information is applied to a system including an information service provider and mobile devices. The information service provider includes a server and a database, in which the server provides security information to the mobile devices and each of the security information is related individually to a security code. The information service provider can transmit updated security information to the mobile devices in an active-push manner in communicative off-peak hours, and at the same time each of the mobile devices would be automatically waken up and connected with the service-provider so as to receive the updated security information. While the mobile device is to request additional information, the passive-pull transmission manner can then be applied by the mobile device to obtain the additional information from the information service provider. Thus, merits of both the active push transmission and the passive pull transmission can be obtained.

The data sampler provides multiple signal samples at a speed twice a symbol rate according to a local clock signal and the inverted local clock signal. The signal samples include a first symbol sample, and a second symbol sample that occurs later than the first symbol sample. The signal samples further include an interpolated sample between the first and second symbol samples. The digital logic circuit compares the first symbol sample with the interpolated sample to generate pre phase correction data, and compares the second symbol sample with the interpolated sample to generate post phase correction data. The pre phase correction data is generated earlier than the post phase correction data. The local clock signal and the inverted local clock signal have substantially a phase difference of 180 degrees.
