Abstract: An X-by-wire control system of a motor vehicle for the control of a main function of the motor vehicle and a secondary function of the motor vehicle which is rated lower by the safety standard to be met in comparison with the main function. The main function can be carried out via a main function assembly of the motor vehicle and the secondary function can be carried out via a secondary function assembly of the motor vehicle, which is spatially separated from the main function assembly. At least one sensor of the secondary function assembly is functionally assigned to the main function. This at least one sensor of the secondary function assembly assigned to the main function on the one hand is only in power supply connection with the main function assembly for supplying operating energy to this sensor and on the other hand in signal exchange connection.

Abstract: A control system for a motor vehicle having a first control unit for controlling a first function of the motor vehicle, a second control unit for controlling a second function of the motor vehicle and a backup control unit. At least the first or the second control unit is connected in a signal-transmitting manner with the backup control unit. In order to ensure the proper execution of functions of a motor vehicle controlled by the control units with the least possible additional overhead, even with a faulty control unit, the backup control unit is configurable in response to the input of an error signal from the first or the second control unit such that the function of the motor vehicle corresponding to the faulty control unit is be controlled via the backup control unit.

Abstract: A control system for a motor vehicle having a first control unit and having a first power electronics unit connected in a signal-transmitting manner to the first control unit for supplying power to a first actuator in normal operation of the control system. In order to ensure proper operation of a control system for a motor vehicle, even in the event of a fault, the control system has a backup control unit and a backup power electronics unit connected in a signal-transmitting manner to the backup control unit for supplying power to the first actuator in a first backup operation of the control system. The backup control unit is connected to the first control unit in a signal-transmitting manner. The control system is transferred from normal operation to the first backup operation as a function of the arrival in the backup control unit of a fault signal.

The first and second control devices are each in a signal transmission connection with at least one sensor and/or at least one actuator. To ensure the proper execution of functions of a motor vehicle controlled by control devices even with a faulty control device with the least possible effort, it is provided that in dependence on the receipt of an error signal from the first control device or the second control device, the respective error-free control device is configured such that the function of the motor vehicle that corresponds to the faulty control device is controlled by the error-free control device.

Abstract: A control system for a motor vehicle, including a first control unit for controlling a first function of the motor vehicle, a second control unit for controlling a second function of the motor vehicle and a backup control unit. To ensure the proper execution of functions controlled of a motor vehicle controlled with the aid of control units even in the case of a defective control unit with preferably little additional effort, the backup control unit is configurable depending on the input of an error signal of the first or second control unit such that an actuator corresponding to the defective control unit is controllable with the aid of the backup control unit. A first backup power electronic module is assigned to the first actuator, and a second backup power electronic module is assigned to the second actuator.

Abstract: A method of switching seamlessly at a receiving end is provided for converting a lower quality digital signal to a higher quality digital signal by initiating a real-time sound reconstruction and restoration process on the lower quality signal. The conversion occurs without interruption of the signal and without re-opening a connection to the signal provider.

Abstract: An apparatus and method for optical data storage and/or retrieval using an optical data storage medium having a spatially-modulated refractive index that can be altered locally with optical methods. Data can be written at a plurality of depths throughout the volume of the medium using a write beam and relatively simple and inexpensive optical components. The write beam stores data locally by physical distortion of the medium at discrete storage locations. The alterations can be detected as variations in the reflectivity of the storage locations using a retrieval beam.

Abstract: A holographic storage and retrieval system for use in co-propagating or counter-propagating geometries having a common optical relay for guiding a signal beam and a reference beam along a common optical axis to a holographic medium to write a hologram therein. The optical relay has an object region imaging quality such that at least 65% and preferably at least 80% of the nominal luminous energy from object pixels is encompassed or "ensquared" by the corresponding image pixels. Additionally, the optical relay has a high total numerical aperture (N.A.) of about 0.83, a pixel N.A. of approximately 0.04 for the signal beam. The system of the invention can be used with holographic storage media in the form of disks, tapes or bulk holographic crystals.
