Abstract: A data communication method includes providing a sender node having a data packet of information. The data packet includes at least one first field and a second field. The second field has content that is dependent upon actual content of the at least one first field. The content of the second field of the data packet is transmitted from the sender node to a receiver node. The receiver node is used to predict the actual content of the first field of the data packet. The receiver node is used to calculate the content of the second field of the data packet based upon the predicted content of the first field. The predicted content of the first field is confirmed to be equivalent to the actual content of the first field. The confirming step includes comparing the calculated content of the second field to the transmitted content of the second field.

Abstract: A data encryption method includes providing a sender node having information to transmit. The information is divided into a sequence of frames. A respective one of a plurality of frame numbers is assigned to each of the frames. At least one nonce and at least one security key are used to perform block cipher encryption and produce within the sender node a respective block cipher encryption output for each of the frames. The information is converted from a sequence of plaintext frames to a sequence of ciphertext frames by use of the block cipher encryption outputs produced within the sender node. The converting is performed within the sender node and after the block cipher encryption outputs have been produced within the sender node. A receiver node is used to ascertain the frame numbers. The at least one nonce is transmitted from the sender node to the receiver node.

Abstract: Methods for predicting a remaining lifetime of an electric energy storage mechanism, in particular a battery in a motor vehicle and devices for implementing such methods are described in which the remaining lifetime is determined by extrapolation with the help of a mathematical model of the energy storage mechanism. This remaining lifetime is defined as the time until reaching any definable limiting values for the minimum efficiency or minimum storage capacity. The remaining lifetime is indicated and, when the level falls below a preselectable threshold, a warning is displayed. The parameters of the energy storage mechanism are adapted continuously to the real values over the lifetime. The anticipated remaining lifetime is determined by extrapolation from the values for the efficiency and/or storage capacity, based on a specifiable charge state and temperature and the minimum values required for the particular application, these values being calculated at regular intervals on the basis of the model and saved.

Abstract: A method for producing a micromechanical component, preferably for fluidic applications having cavities. The component is constructed from two functional layers, the two functional layers being patterned differently using micromechanical methods. A first etch stop layer having a first pattern is applied to a base plate. A first functional layer is applied to the first etch stop layer and to the first contact surfaces of the base plate. A second etch stop layer, having a second pattern, is applied to first functional layer. A second functional layer is applied to the second etch stop layer and to the second contact surfaces of the first functional layer. An etching mask is applied to the second functional layer. The second and the first functional layer are patterned as sacrificial layers by the use of the first and the second etch stop layer by etching methods and/or by using the first and the second etch stop layer.

Abstract: A method for handling a faulty device in a vehicle communication network is provided, which is used to identify devices that are either faulty, were removed from the vehicle communication network or were switched off, and to automatically initiate a fault-remedying measure. An expanded, device-specific driver having diagnostic functions is loaded by another device of the network to send a test signal to the faulty device. Either the faulty device is restarted or the faulty device is switched off depending on the reaction to the test signal. If a device is removed from the network, this is indicated in a database. A bus manager will inform other devices connected to the network that this device was removed from the network. Due to a classification of the individual devices connected to the network, not every device is able to perform the fault handling, but rather only suitably classified devices. Misuse is thereby prevented.
