Abstract: An unmanned aerial vehicle (UAV) navigation obstacle avoidance system and method thereof are introduced. The UAV navigation obstacle avoidance system provides with functions of automatically controlling the UAV motive power sources to control the flight of UAV and avoid the obstacle. The system comprises a sensing device, a signal processing module, a communication module, a control module. The sensing device detects the relative direction, velocity and distance between a UAV and a dynamic or static obstacle. The sensing device also detects the real-time position, flight attitude and inertia signals of the UAV. The signal processing module generates a UAV flight control signal. The control module receives the UAV flight control signal and controls each of the UAV motive power sources. Therefore, the system achieves the purpose of controlling flight and obstacle avoidance and forward to the original planned follow-on flight route after the avoidance.

Abstract: The present invention relates to a bidirectional voice transmission system and a method thereof, wherein the system timing of the system is divided into three time slots for carrying a control signal, a broadcast voice signal and a mobile device voice signal. The bidirectional voice transmission system is able to carry out the signal transmission by way of frequency frogging, so as to effectively avoid the signal interference from occurring between any two different signal transmitting and receiving devices. Besides, all of the mobile devices can be added into the bidirectional voice transmission system by way of dynamic building, without using any specific communication interface. The most important is that, the number of node routers can be expanded to about 65,000 in order to apply the bidirectional voice transmission system in a huge range network communication or a wild rescue field.

Abstract: The present invention relates to a wireless communication locating method, the method uses a first wireless receiver, a second wireless receiver and a third wireless receiver (i.e., a first rescuer, a second and a third rescuer) to receive mayday and RSSI signals outputted by a person to be rescued, therefore the position of the person to be rescued can be precisely located after a backend signal-processing platform processes and calculates the mayday and RSSI signals. Through the method, each of rescuers are able to output a prompting signal to the person to be rescued by way of frequency synchronization, so as to give the person to be rescued hopes and a message that rescuers are coming. The method also includes the advantages of high damage resistance ability, high expansibility and can be easily operated, such that the purpose of immediate rescue can be achieved by using the method.
