  • Patent number: 11904865
    Abstract: Provided is an intelligent safe vehicle speed measurement method and an system capable of considering a state of a road surface, including: a laser scanning unit configured to obtain road surface textures and simulate contact under different vehicle loads and tire patterns; a wireless communication unit configured to obtain the model, load and tire information of incoming vehicles, offer a best-matching braking distance by search through database; a skid resistance prediction unit configured to obtain environmental parameters to correct the obtained best-matching braking distance, and offer a safe speed for incoming vehicles; and a warning reminder unit configured to broadcast the safe running speed to incoming vehicles. This system communicates between the vehicle and road, obtains the information from incoming vehicles in real time, and broadcasts the safe speed to incoming vehicles, ensuring the safety of the incoming vehicle during running.

  • Publication number: 20220229211
    Abstract: An image detection device includes an image detection optical system including a liquid resonant lens; an image detector configured to detect an image corresponding to a detection phase of a drive signal through the image detection optical system; a range determination unit configured to determine a first half or a second half of a cycle of the drive signal as a designated allowable range of the detection phase based on whether a phase delay shown by a variation waveform of a focus position is positive or negative; a detection phase setting unit configured to set the detection phase in the designated allowable range; and a detection control unit configured to control an image-detection timing by the image detector to a timing offset from the detection phase by an angle corresponding to the phase delay.

  • Publication number: 20210150103
    Abstract: The disclosure discloses a system and method for predicting a vibration of a bicycle when being rode on a road. The method first uses a pressure film to obtain a contact interface between a road and a bicycle tire, and then, based on the contact interface, a unit bearing area (Bu) and an average stress peak distance (Spa) are calculated. Next, taking the above parameters as variables, a predicted vibration value (Pv) is calculated based on calculation formulas provided by the present disclosure. Finally, the predicted vibration value Pv is compared with a comfort-level threshold perceived by a cyclist of the present disclosure, which can quickly and effectively grade and predict a comfort level when riding a bicycle on a section of an asphalt road.

  • Publication number: 20210010904
    Abstract: The present disclosure provides a method and an apparatus for evaluating a degree of injury of a rider's head colliding with a pavement and a test method for testing the apparatus. An impact acceleration of a head model falling from a certain height and hitting the pavement is obtained through a self-made test apparatus, a TBS value is calculated after processing the obtained impact acceleration, and a possibility of the degree of the injury to the rider's head colliding on a test pavement after falling is obtained by inquiring a look-up table of possibility of injury degree of the head of the rider corresponding to the TBS provided by the present disclosure, for evaluating safety hazard when falling on the pavement.
