Abstract: A computing system has a computing device. The computing system has an input data path, which unidirectionally connects an interface device to the computing device, and an output data diode, which unidirectionally connects the computing device to the interface device. The input data path has a data lock which is connected to the interface device by a first terminal and to the computing device by a second terminal. The data lock has a storage unit for storing data and is configured such that the storage unit can be selectively connected solely to the first or second terminal but not to both terminals simultaneously. The computing device accepts data from the interface device solely if the data is transmitted to the computing device from the interface device via the input data path within a transmission session initiated by the computing device using the output data diode.

Abstract: A computing system includes a computing device and an input data path connecting an interface device to the computing device. The input data path has at least two data relays and at least one buffer memory temporarily storing data. Each of the data relays has first and second terminals and a central terminal and selectively interconnects the first and central terminals or the second and central terminals and leaves the first and second terminals constantly separated from each other. The first terminal of a first relay is connected to the interface device, and the second terminal is connected to the computing device. The central terminal of the first data relay is connected to the buffer memory. The intermediate buffer memory is selectively connected by the first data relay solely to the interface device or the second terminal of the first data relay, but not to both simultaneously.

Abstract: A method for operating an electronically-controlled headlamp system of a motor vehicle capable of generating different light distributions, including a high-beam distribution and a low-beam distribution. The roadway region illuminated by the headlamps during the adjustment of the high-beam distribution comprises a high-beam region and a dimmed region, and the border between the high-beam region and the dimmed region is defined by at least one high-beam edge. An electronic headlamp controller is operable to displace or move the high-beam edge at a rate that is variable depending on a current driving scenario. The driving scenario may include a condition of a vehicle environment, a traffic scenario, a vehicle state, and an activity of vehicle driver. The transition duration between two different light intensities, the light-intensity adaptation, and the separation between a high-beam edge and an object (such as another vehicle), may also be varied depending on the driving scenario.
