An embodiment of the invention provides a multimedia evaluating system, a multimedia evaluating device and a multimedia evaluating method. The multimedia evaluating system comprises a display unit and the multimedia evaluating device. The display unit is used for playing multimedia data. The multimedia evaluating device is coupled with the display unit for acquiring and recoding face expression of an observer for the multimedia data and generating image evaluating data according to the face expression of the observer. The image evaluating data comprise a plurality of expression labels. The expression labels respectively have an expression character and a playing time which corresponds with the multimedia data; wherein, the multimedia evaluating device determines the type of the multimedia data according to the image evaluating data. The multimedia evaluating system can determine content and type of the multimedia data through analyzing the real feeling of the observer to the multimedia data, thereby replacing the prior characters and subjective comments and improving interest of the observer.

The invention provides a paper currency form detection method, and belongs to the financial equipment field. The paper currency form detection method includes the steps: by means of two first sensorswhich are symmetrically arranged at two sides of the transmission surface of the first transmission path, acquiring the first state information of the paper currency transmitted on the first transmission path; and based on the first state information, acquiring the form of the paper currency. The paper currency form detection method can determine whether the paper currency are in the inclined state or the state that the neighboring paper currency are connected together, can make relatively more comprehensive prediction of the state of the paper currency, and can improve the determination accuracy. The invention also provides a paper currency form detection device. The paper currency form detection device includes a first transmission path, first sensors and a processor, wherein the two first sensors are symmetrically arranged at two sides of the transmission surface of the first transmission path in the transmission direction being perpendicular to the first transmission path; and thedistance between the two first sensors is not more than the standard length of paper currency. The paper currency form detection device has the advantages of being simple in structure, being convenient to use, being high in detection efficiency and being high in accuracy. The invention also provides self-service depositing and withdrawing equipment. The self-service depositing and withdrawing equipment includes the paper currency form detection device, and has higher usage stability.

The present invention provides a quantitative analysis method based on CT image, involving the field of image processing technology, including the following steps: S1: Create a machine learning model; S2: Enter CT images for processing; S3: generate 3D lesion data, calculate new crown pneumoniaQuantitative factor; S4: Determine whether the quantification factor score is higher than the critical threshold; if it is a new crown patient, and execute the S5; otherwise, the patient does not suffer from new crown pneumonia; S5: Repeat S2 to S4, accumulating patients with CT image quantitative factor multiple times many times, Get the trend of the patient's condition.The quantitative analysis method based on CT image based on CT image is simple and convenient. The CT image is generated to generate 3D lesion data. By calculating and quantifying the lesion, doctors can intuitively observe information such as lesions, size, and changes.It can effectively judge whether the patient suffers from new crown pneumonia, and can further judge the trend system of new crown patients.

The invention discloses an intelligent wearable device with a one-key call for help function, which includes a call for help system, and the call for help system includes a monitoring unit that monitors and records relevant information of the wearer in real time; a prompt unit that sends a call for help to the wearer / rescuer Prompt or prompt the current health status of the wearer / rescuer; one-key call for help unit, execute the call for help operation; analyze the control unit, the analysis control unit is electrically connected with the monitoring unit, the prompt unit and the one-key call for help unit, and determine the monitoring unit Whether the monitored relevant information is normal, and / or analyze and compare the relevant information monitored by the monitoring unit with the relevant information previously stored in the analysis control unit to determine whether it is normal, and if it is abnormal, the control prompt unit will send a call for help to the wearer, If there is no answer, the one-key call for help unit will be activated automatically to call for help. In the present invention, calling for help is timely and effective, has a wide application range, and avoids misoperation.
