  • Publication number: 20150350819
    Abstract: A Bluetooth transmission system is composed of at least a monitoring device and at least a mobile communication device. The monitoring device can detect and produce a biosignal, an environmental signal, and a broadcast signal, which are allocated with a universally unique identifier (UUID); further, the monitoring device has an information packet generation module that generates an information packet with the UUID, biosignal, environmental signal or broadcast signal, and then automatically sends the packet to a mobile communication device. In addition, when the mobile communication device receives information packet from different monitoring devices, it will decode the information packet, identify corresponding monitoring device through its UUID, and receive corresponding signal. Therefore, this invention can provide communication between at least a mobile communication device and several monitoring devices.

  • Patent number: 8199929
    Abstract: An anti-pop circuit is coupled with a sound outputting device to prevent a “pop” sound form being mixed into a sound signal. The anti-pop circuit includes a control signal generator and a fist diode. The control signal generator generates a control signal with a high level state and a low level state. The first diode couples with the sound outputting device. The sound signal is transferred to the first diode when said first diode is in a forward bias state, and the sound signal is outputted from an output end of the sound outputting device when the first diode is in a reverse bias state.
