Abstract: An ultrasonic imaging system for generating an ultrasonic image of a motion status of an object according to at least an ultrasonic motion signal generated by detecting the motion of the object is provided. The ultrasonic imaging system includes a demodulation module, an analog sub-array beamformer, a filter, an analog-to-digital converter and an image processing module. The demodulation module receives and demodulates the ultrasonic motion signal so as to generate and send at least a demodulated signal. The analog sub-array beamformer receives the demodulated signal, generates and sends an analog sub-array beam signal according to the demodulated signal. The filter receives and filtering the analog sub-array beam signal. The analog-to-digital converter converts the analog sub-array beam signal filtered by the filter into a digital sub-array beam signal. The image processing module receives the digital sub-array beam signal so as to generate an ultrasonic image of the motion of the object.

Abstract: An exemplary ultrasonic diagnostic system includes a portable ultrasonic diagnostic apparatus and a cloud computing system. The portable ultrasonic diagnostic apparatus includes an ultrasonic sensing unit, a front-end circuit, a data compression unit and a communication unit. The ultrasonic sensing unit is configured to sense a signal reflected from a measured object. The front-end circuit is configured to perform a pre-processing on an output of the ultrasonic sensing unit. The data compression unit is configured to receive an output of the front-end circuit and determine whether to perform a data compression process on the output of the front-end circuit according to a selected result. The communication unit is configured to receive an output of the data compression unit and further transmit the output of the data compression unit to the cloud computing system.

Abstract: The present invention provides a method and system for transmitting and receiving vehicle information, in which a wireless transmitting and receiving unit and a vehicle computer recording a first information is disposed in the vehicle, and a processing computer is disposed in a vehicle station. When the vehicle enters the vehicle station, the vehicle wirelessly transmits the first information to the processing computer according to a request signal. After that, the processing computer wirelessly transmits a second information to the vehicle computer at a specific time point. By means of the method and system of the present invention, it is capable of exchanging information between the vehicle and vehicle station in a wireless transmitting and receiving way so as to save the waiting time for maintenance and management.
