  • Publication number: 20230271617
    Abstract: The present invention provides a risky driving prediction method and system based on a brain-computer interface, and an electronic device. The risky driving prediction method based on the brain-computer interface includes: performing, by a driver, at least one responsiveness test item before starting a vehicle; applying a brain-computer interface to acquire an electroencephalogram signal of the driver performing the at least one responsiveness test item, and analyzing the electroencephalogram signal to generate feedback information; and analyzing the feedback information based on a preset test standard to determine whether the driver has a risky driving behavior. Therefore, by using the risky driving prediction method, it can be detected whether the driver is in a state suitable for driving the vehicle without requiring the driver to do any body movement or language response.

  • Publication number: 20210371235
    Abstract: The present invention provides a contactless elevator control system and method. The system comprises an infrared touch sensor, a relay control device and an elevator button control device, wherein: the infrared touch sensor emits an array of multiple infrared beams, receives reflected infrared beams, calculates a vertical and lateral displacement, determines a corresponding coordinate information, calculates a corresponding elevator button, and sends a corresponding control; the relay control device drives the corresponding relay contacts to close. The solution uses the infrared touch sensor to achieve contactless control of elevator buttons, reducing the risk of spreading bacteria and viruses when touching the elevator buttons.

  • Patent number: 10618522
    Abstract: An in-vehicle monitoring and intervention system for detecting whether a driver in a vehicle is drowsy by monitoring a plurality of physiological signals of the driver is provided. The in-vehicle monitoring and intervention system includes at least a processor and an apparatus, the apparatus can be integrated into a seat belt or attached thereto as a discrete hardware apparatus, which includes at least an ECG sensor, a respiratory sensor, an acceleration sensor, a filtering system, and an intervention module. The filtering system further comprises one or more filters for suppressing noise and reducing motion artifacts. The processor is configured to compare the detected physiological signals with the signals stored in a learning module of the in-vehicle monitoring and intervention system for determining the drowsiness state. If the driver is determined to be drowsy, a warning signal is outputted to alert the driver.
