METHOD AND DEVICE TO WIRELESSLY TRANSMIT ACOUSTIC CARDIAC SIGNALS

摘要

The present invention relates to a method to wirelessly transmit acoustic cardiac signals during image medical test. Acoustic cardiac signals are obtained from a sampling frequency by an optical microphone, and the sampling frequency includes one cycle lasting period. The wireless transmission of the acoustic cardiac signals is achieved by a transmitting device, and the transmitting device includes a control unit and a transmitting unit. The transmitting unit includes a signal modulating unit, and the signal modulating unit includes a transmission diode and a reception diode. The wireless transmission method includes an activating step of activating the transmission diode with the control unit for a period including an activation time, which is shorter than the cycle lasting time; a signal discharging step of discharging a signal with the transmission diode for the activation time, and optically modulating the discharged signal based on the acoustic cardiac signals; a step of obtaining the modulated signal with the reception diode for the activation time; and a step of wirelessly transmitting the signals.;COPYRIGHT KIPO 2016
