  • Publication number: 20230194173
    Abstract: [OBJECT] To provide a fractionating device capable of stably fractionating powders such as cement raw materials by a simple configuration. [SOLUTION] A fractionating device 1 for fractionating some of a powder (cement raw material) R falling in a chute (main body) 2, wherein the fractionating device is equipped with a screw conveyor 5 which passes through the chute, a part of a casing 5a opening inside the chute, and receives part of the powder from an opening (inlet) 5b, and a collision separation member (collision separation rod) 4 which is provided above the screw conveyor in the chute and collides with an object when an object of a predetermined size or larger falls, and prevents the object from falling directly onto the screw conveyor.

  • Publication number: 20230100810
    Abstract: A safe driving determination apparatus includes an angle value calculation part that calculates an angle value indicating a face direction angle of a driver with respect to the traveling direction, and a determination part that determines whether or not the driver is in a state of being inattentive to the road ahead on the basis of whether or not an integrated value of angle values during a past predetermined first determination period is equal to or greater than a threshold value, wherein the determination part does not determine that the driver is in a state of being inattentive to the road ahead if the angle value of the driver is less than a second threshold value at the present moment, even if an integrated value of angle values during a past predetermined first determination period is equal to or greater than a first threshold value.

  • Publication number: 20230081020
    Abstract: A driving assistance device 1 is provided with: three or more detection units 5a to 5d which are configured to detect a likely-to-be-dozing state in which likelihood that a driver of a vehicle is dozing is high by different indices and at prescribed intervals; a state determination unit 34 which determines that the driver is in a dozing state when the likely-to-be-dozing state is detected by at least two of the detection units; and a warning control unit 36 which causes a warning device 6 to issue a warning when the state determination unit 34 determines that the driver is in the dozing state.

  • Patent number: 11443534
    Abstract: In this vehicular monitoring device, an imaging unit 2 captures an image of the driver of a vehicle. A driving state measurement unit 70 analyzes the image captured by the imaging unit 2 and measures a plurality of driving states including the eye opening degree of the driver. A travel state determination unit 71 determines the travel state of the vehicle. An alarm determination unit 72 uses the driving states and the travel state as a basis to determine whether to activate an alarm device 5. When a statistical amount calculated from time series data for the eye opening degree acquired from the driving state measurement unit 70 is outside of a predetermined normal determination reference range, the driving states other than the eye opening degree are normal, and the travel state is determined to be normal, the alarm determination unit 72 causes the driving state measurement unit 70 to perform eye opening degree detection processing again.

  • Patent number: 11267478
    Abstract: An imaging unit 2 captures an image of a driver of a vehicle. A driving state measurement unit 70 analyzes the image captured by the imaging unit 2 and measures a plurality of driving states including the driver's face orientation angle. A traveling state determination unit 71 determines the traveling state of the vehicle. An alarm determination unit 72 determines whether to activate an alarm device 5 on the basis of the driving states and the traveling state. When the face orientation angle acquired from the driving state measurement unit 70 is out of a normal determination reference range, and it is determined that the driving states other than the face orientation angle are normal and the traveling state is also normal, the alarm determination unit 72 causes the driving state measurement unit 70 to re-execute the face orientation angle detection process.

  • Patent number: 10286790
    Abstract: An electric vehicle is able to be charged from a power source via a supply side controller. The supply side controller retrieves and acquires vehicular information from the electric vehicle as an electric connection is established with the electric vehicle. The supply side controller stores the retrieved vehicular information. The vehicular information may contain charging information used for a charging control and non-charging information not used for the charging control. An information device, such as a smart phone, requests to supply the vehicular information. In response to the request, the supply side controller supplies the stored vehicular information to the information device without accessing the battery charger and the vehicular functional device. Accordingly, it is possible to supply the vehicular information without rebooting the controller on the vehicle in response to the request from the information device.
