摘要:
In at least some embodiments of the present disclosure, an emergency situation notification device installed in a vehicle transmits a message for notifying an occurrence of an emergency situation of the vehicle when the emergency situation occurs, and an emergency situation display device installed in a street light performs a turning-on operation or a blinking operation according to reception of the message for notifying the occurrence of the emergency situation. Further, when a message notifying that an emergency vehicle is currently being dispatched is received from an emergency situation notification device which may be installed in the emergency vehicle, etc., a control center server controls emergency situation display devices, which are installed in street lights in the proceeding direction of the vehicle currently being dispatched, to properly generate warning signs.

The present invention relates to an adaptive medical image transmission device and method which consider communication state and residual power. The adaptive medical image transmission method induces an image receiving device to post-process a result of medical image processing performed by a medical image transmission device by: receiving medical image data by means of a probe; sensing communication throughput indicative of a communication state between the image transmission device and the image receiving device; variably determining a data rate required to transmit data on the basis of a preset data rate based on the sensed communication throughput; performing medical image processing by selecting a signal path which satisfies the determined data rate with respect to the medical image data; and transmitting the result of the medical image processing to the image receiving device according to the determined data rate.
