The present invention relates to a brake-by-wire actuator for actuating the brake system of a motor vehicle, comprising a simulator which can be acted upon by a brake pedal, with a signal of an actuation sensor being sent to an electronic control unit which controls a pressure source in response to the signal of the actuation sensor, and wherein an output of the pressure source is connected to a distributor device for the brake force and actuates individual wheel brakes of the vehicle, also comprising means for enabling actuation of the brakes by muscular power within a fallback mode. In order to provide an improved fallback mode in a brake-by-wire actuator, according to the invention, a lost travel is provided between a first actuation component such as a brake pedal in particular or a component articulated at the brake pedal and an actuation component that is connected downstream in the flux of force, in particular an input member, in order to uncouple the first actuation component mechanically from the reactions of force of the motor vehicle brake system in the by-wire mode.

Image browsing through memory-stored items, such as a library of images or desktop windows, is efficiently performed by arranging images in partially overlapping fashion and generating a second-level image for each overlapped image that is contacted by a user-manipulated cursor. The second-level image is a “transitory” image, since it is removed as soon as the cursor is displaced from the corresponding first-level image. Thus, by placing the first-level images in a diagonally extending stack, straight line movement of the cursor will initiate a sequential presentation of transitory images for the images in the stack. In one embodiment, the display also includes an incrementing icon and a decrementing icon that are employed to provide substitute stacks. Moreover, a third-level image is formed in a separate window when the user selects one of the images from the stack. This third-level image has more permanency, since it remains in the display window after the stack has been substituted. The images may be digital photographs, but other applications are contemplated.
