Provided are an awakened-state maintaining apparatus and an awakened-state maintaining method that maintain an awakened-state of a driver. In the awakened-state maintaining apparatus (100), a visual-stimulation control unit (107) calculates an initial displaying position that is in accordance with the product of initial setup time and detected vehicle speed. A displaying means displays on the initial displaying position a visual stimulation image pertaining to a visual-stimulation virtual object that will evoke an awakened-state, and also updates the visual stimulation image using a visual effect wherein the visual-stimulation virtual object is displayed so as to seemingly approach the vehicle at the detected speed, in accordance with the time elapsed since the visual stimulation image was first displayed. An audio signal control unit (105) outputs an audio signal and a vibration control unit (106) outputs a vibration, when the initial setup time has elapsed since the visual stimulation image was first displayed. Since, in such a way, a driver is able to sense that the vehicle that he / she is driving has run over the visual-stimulation virtual object, which was displayed so as to seemingly make a gradual approach to the vehicle, with his / her visual, hearing, and tactual senses, the awakened-state of the driver is able to be maintained.

The invention discloses a fatigue driving monitoring, reminding and early warning method and system based on a computer vision technology, and the system comprises a fatigue value real-time monitoring system, a fatigue value automatic reminding system and a fatigue value information early warning system.The fatigue value real-time monitoring system is used for identifying the fatigue characteristic posture of the driver and obtaining a fatigue value grade according to the occurrence frequency of the fatigue feature posture and the driving time; the automatic fatigue value reminding system is used for receiving the fatigue value grade, obtaining real-time position information of the vehicle and reminding a driver of the corresponding grade according to the fatigue value grade; the fatigue value information early warning system is used for receiving the fatigue value grade information and the vehicle real-time position information to obtain a fatigue safety index, obtaining a fatigue road condition cloud picture according to the fatigue safety index, and sharing the fatigue road condition cloud picture to all traffic management departments and all drivers on the expressway for early warning. The condition of fatigue driving on the highway is reduced, and the hazard of traffic safety accidents caused by fatigue driving is reduced.

This radiation imaging system has a radiation source, a case, and a radiation detection device which is housed in the case, and is equipped with a radiation detector having a conversion unit that converts radiation from the radiation source, which has passed through at least a subject, to radiation image information, wherein a prediction is made as to whether the afterimage phenomenon has occurred in the conversion unit, and if it is predicted that the phenomenon has occurred, at least the conversion unit is moved.

The invention discloses an electrical stimulation anti-fatigue system and a control method. A fatigue state detection module is used to detect the driver's fatigue state, and the detected driver's fatigue state information is fed back to the control module. The state information matches the control signal, and transmits the control signal to the electrical stimulation module, and then uses the electrical stimulation module set on the driver's seat to generate a stimulating current to stimulate the driver according to the received control signal. Electric pulses are applied to the driver's skin, so that the current flowing through the electrodes can be used to stimulate the tactile receptors in the skin to work. At the same time, because the driver's ability to perceive external signals is reduced in a fatigued state, the electrical stimulation can directly act on the skin. The human nerves and the brain are easier to perceive, so as to achieve the purpose of keeping the driver awake. The device has a simple structure, is easy to wear, and has an obvious stimulating effect.
