  • Publication number: 20240123834
    Abstract: A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated. The information acquisition unit acquires information on a state of the vehicle. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.

  • Patent number: 11504084
    Abstract: A radiographing control apparatus includes a hardware processor. A radiographic imaging apparatus is exposed to a radiation from an irradiating apparatus through the subject. The hardware processor retrieves pre-exposure image data which the radiographic imaging apparatus generates by performing a pre-exposure to the subject at a pre-exposure dose of less than a dose of a subsequent main exposure, and calculates a total dose required to obtain diagnostic image data to be used for diagnosis. The hardware processor outputs a main exposure dose based on the calculated total dose to the irradiating apparatus and the radiographic imaging apparatus. The hardware processor retrieves main exposure image data which the radiographic imaging apparatus generates by performing the main exposure to the subject at the main exposure dose, and combines the main exposure image data with the pre-exposure image data to generate the diagnostic image data.

  • Publication number: 20220117574
    Abstract: A radiation imaging system includes a first hardware processor. The first hardware processor executes control such that before main imaging is executed at a main dose, pre-imaging is executed at a pre-dose that is lower than the main dose. The first hardware processor derives an imaging condition for the main imaging based on a pre-image acquired in the pre-imaging, switches a control mode to one of a pre-image checking mode and a short-time imaging mode, and notifies which control mode between the pre-image checking mode and the short-time imaging mode is used to execute the control. The pre-image checking mode being a mode in which the pre-image is displayed after executing the pre-imaging. The short-time imaging mode being a mode in which the pre-image is not displayed after executing the pre-imaging before the main imaging.
