Abstract: Techniques are disclosed for facilitating the process of undoing and redoing modifications that are made to content using an online content management system (CMS). As a user makes changes to content, such as by editing a webpage using a web-based CMS, a history of the user's modifications is generated and stored locally on the client. When the user invokes an undo command, the modification history can be used to determine a previous state of the content and restore the content to that previous state. Similarly, when the user invokes a redo command, the modification history can be used to return to a state that had previously been undone. In some embodiments, the process of undoing or redoing the user's modifications is selectively performed on either a client side or a server side of the online system, depending on the type of content that is being manipulated.

Abstract: A planetary gear, in particular a multi-stage planetary gear, includes at least two sun wheels, which are disposed coaxially one behind the other. A hydrodynamic axial bearing is arranged between the sun wheels.

Abstract: A method for determining whether an error is present or not in a motor vehicle, a discrete state, in which the motor vehicle is presently in, being ascertained with the aid of a state machine, a decision being made, depending on the ascertained discrete state, whether an error is present or not, whereby the states of the state machine include acceptable states and unacceptable states, then, if the ascertained discrete state is an unacceptable state, the motor vehicle is transferred into an acceptable state.

Abstract: In a method for checking the plausibility of objects in driver assistance systems for motor vehicles is described, two measured variables are derived from position data from two object position-finding systems of the vehicle that operate independently of one another, for an object located by the two position-finding systems, one variable for each position-finding system, these variables representing one and the same physical parameter, and the two measured variables are then checked for consistency, which is characterized by the fact that the parameter is the time to collision of the vehicle with the object, which is calculated in advance.

Abstract: A method for activating a two-stage switching valve including a first stage which has a small flow cross-section and a second stage which has a larger flow cross section, the switching valve being situated between a main brake cylinder and a hydraulic pump in a hydraulic brake system. The pressure equalization knock on opening the switching valve is substantially reduced by activating the switching valve in a first control phase via a control signal having a low amplitude, due to which only the first stage of the valve is first opened, and by activating the valve in a second phase via a control signal having a higher amplitude.

Abstract: A device for determining the saturation point of a vacuum brake booster having a vacuum chamber and a working chamber that are separated from one another by a membrane. The reaching of the saturation point can be recognized simply and precisely if the vacuum prevailing in the vacuum chamber is measured using a pressure sensor, and the output signal of the pressure sensor is evaluated by an electronic evaluation system that calculates the saturation point using a mathematical function, taking into account only the pressure prevailing in the vacuum chamber.
