Abstract: A device connectable to a control device for simulating an effect of at least one electrical or electronic load being connected to at least one terminal of the control device includes: a processing unit configured to at least one of compute and make available a control variable corresponding to the effect of the at least one electrical or electronic load that is to be simulated, and a power supply device: The power supply device includes at least one auxiliary voltage source configured to form at least one of a current source and a current sink and configured to receive the control variable from the processing unit. The at least one auxiliary source is configured to draw a current from the control device or impress a current on the control device based on the received control variable.

Abstract: A method for simulating an effect of at least one electrical/electronic load includes: providing a controllable power supply unit that is connected to at least one terminal of a control unit; and simulating a first current theoretically flowing through a simulated load at the at least one terminal by drawing a second current from the control unit by the controllable power supply unit or impressing a third current on the control unit by the controllable power supply unit.

Abstract: A hierarchical system is used to store data items easily capable of thumbnail representation (such as images). Such a hierarchical system may allow a folder (or other grouping) to contain both data items and sub-folders. The display of such a folder uses two display areas. In one display area, sub-folders are displayed using a list view, where text is the primary method for the display of the sub-folders which are contained in the folder. In the other display area, a grid view is used to display the data items. Thumbnail images are the primary components of the grid view. Functionality available to a user will change based on whether the user is browsing the list view or the grid view.

Abstract: A list of digital elements is represented by a list of graphical elements where one of the graphical elements is highlighted. The non-highlighted graphical elements are overlapped over one another based on particular overlapping heuristics.
