Abstract: For optimization of the mode of operation of processor systems, there is proposed a bus connection which divides bus transactions substantially into transactions that must be executed in strictly logical sequence and that do not have to be executed in strictly logical sequence. Subsequently the transactions are again arrayed one after another in serial manner for further processing, with the feature that, in given cases, transactions that do not have to be executed in strictly logical sequence are moved ahead of transactions that must be executed in strictly logical sequence. The result is a gain in time and thus performance for the processor system.

Abstract: The invention relates to a plug-in connection between a printed-board connector (3) and a mating connector (13), said printed-board connector (3) being provided with a connector shield (6). Between the printed-board connector and the mating connector an I/O board (1) with an opening (2) is interposed via which the printed-board connected and the mating connector can be contacted and fastened to each other. Since the printed-board connector is not screwed together with the I/O board according to the most recent standard, a support element is provided which forces the I/O board (1) against the connector shield (6) of the printed-board connector (3) when the mating connector (13) is screwed together with the printed-board connector (3).

Abstract: The invention relates to a method and a device for matching the phase between the pixel clock of a graphics card and the sampling clock of a flat-panel display with an analog interface in a system comprising flat-panel display, graphics card and computer. Herein the rising edge of a video pulse of a sufficiently bright image spot in the first image column close to the back-porch region is determined. The falling edge of a video pulse at a sufficiently bright image spot in the last image column close to the front-porch region is determined, and the phase is adjusted such that the sampling instant is situated approximately at the midpoint between the rising and falling edges of a video pulse.

Abstract: A method for controlling the information exchange between at least one central computer and a subscriber via a control system. Following a request from the subscriber, the control system receives the data relevant to the subscriber from the central computer in a first control phase. In a second control phase, information transmitted from the subscriber is processed and transmitted to the central computer. The first and the second control phases are defined by a single control program.

Abstract: A method for monitoring the setting of the phase between the pixel clock rate of a graphics card and the sampling clock rate of a flat screen having an analog interface includes the steps of setting a flag if the phase of the flat screen has been set by the user. The flag is interrogated upon switching on the flat screen and/or upon a change of the video mode at a computer and/or an exchange of the graphics card and/or upon an exchange of the computer. A display is provided or a setting of the phase is initiated if, during the interrogation, it is ascertained that the flag is not set. A device for monitoring the setting of the phase between the pixel clock rate of the graphics card and the sampling clock rate of the flat screen is also provided.

Abstract: For accomplishing an interruption-free power supply operation of a system unit (HDD) in a computer system with a plurality of system computers (Sa; Sb) sharing the system unit (HDD) without having the limitation to a local location, a method and an arrangement is [sic] proposed in accord wherewith the operation of the respective station computers (Sa; Sb) respectively ensues with their own interruption-free power supplies (USVa; USVb) and, for the power supply of the shared system unit (HDD), the shared system unit (HDD) is always connected to an active interruption-free power supply (for example, USVb) by an automatically switching switchover (PCS) that monitors the voltage of its inputs.

Abstract: A new operating system is provided with two layers having different access authorizations. For security reasons a memory for basic system routines can be accessed only from a kernel layer, but not from an application layer. By providing a respective program that is executable in the respective layer, it is possible, while complying with the security stipulations, for the memory to be accessed and, consequently, for a new version of the basic system routines to be made available to the data processing system.
