Abstract: The present invention provides a biomedical monitoring system combining a mobile device. Signals can be transmitted between the sensing device and the mobile device via the audio interface by modulating and demodulating the audio signals or encoding and decoding the digital signals. Thereby, it can be applied extensively to mobile devices having audio jacks and thus bringing more convenience. In addition, because the mobile devices inherently have the functions of operational processes, transmission, storage, interface operations, result displaying, network connection, image extraction, and power supply, the required components in sensing devices can be simplified substantially and hence reducing the volume and the manufacturing cost.

Abstract: A bridging device with power-saving function includes first and second interfaces, first and second physical layer processing devices, and a controller. The first interface is utilized for coupling a first external device complying with the first interface. The first external device receives a device request signal, and accordingly sends back a device response signal through the first physical layer processing device. The second interface is utilized for coupling a second external device complying with the second interface. The controller is coupled between the first and the second physical layer processing device for transmitting the device request signal with the predetermined frequency to the first physical layer processing device in order to receive the device response signal. When the controller does not receive the device response signal, the controller turns the second physical layer processing device off.
