  • Patent number: 11117558
    Abstract: This vehicle brake device comprises: a simultaneous driving determination section which determines whether it is necessary to simultaneously drive an upstream-side motor and a downstream-side motor; and a PWM control section which, when the determination result by the simultaneous driving determination section is in the affirmative, changes the duty ratio of the PWM signal to be output to the upstream-side motor so as to be smaller than when the determination result by the simultaneous driving determination section is in the negative, and uses PWM control to drive the upstream-side motor.

  • Publication number: 20210275899
    Abstract: A computer system including a content monitoring service of a menu application is provided. The content monitoring service pre-fetches data for a target application based on a data template defined for the target application, and stores the pre-fetched data in a cache of the menu application. The menu application presents a window in a first presentation state, where the window corresponds to the target application and includes content based on the pre-fetched data in the cache. The computer system further includes a window application that, upon a user selection of the window, receives a copy of the pre-fetched data from the cache and presents the window in a second state based on the data template.
