A sensor device for transmitting a sensor parameterization between sensors. The sensor device includes a first sensor with a sensor parameterization and a second sensor. The first sensor and the second sensor communicate with each other via a communication link. The first sensor sends the sensor parameterization to the second sensor via the communication link. The second sensor receives and accepts the sensor parameterization. The second sensor further provides the first sensor with the energy required to transmit the sensor parameterization via the communication link.

A method for preprocessing data records for rendering in a diagram having first, second and third coordinates, wherein values of the first coordinate of the diagram, and/or values of the second coordinate of the diagram are discretized in bins. The method includes assigning to each bin of the first coordinate or to each bin of the second coordinate, data records having a value of the first coordinate or values of the first coordinate and the second coordinate, checking a number of data records that is assigned to each bin; when only one data record is assigned to a bin, instructing rendering the diagram using a third coordinate value of the data record, and when multiple data records are assigned to a bin, instructing rendering the diagram using selected third coordinate values, determined according to a predetermined criterion in which at least one value is chosen and/or aggregated.

Data preparation for graph depiction

A method for the time-synchronized processing of data of a field device of process automation, in which the data and/or data changes are saved together with an internal time stamp of an internal timer of the field device in a memory of the field device; during the reading process of the data from the field device, a path difference being detected of the internal timer of the field device and a timer of the control unit by which the data is read, the internal time stamps are corrected by the path difference, and are saved as corrected time stamps together with the data.

During the compression of digital image data, the desired level of detail, therefore the compression level, is defined at different values 'for different image regions'. The definition of the level of detail can be automatic and/or controlled by the user. As a result of this it can be achieved for more interesting image regions to be less compressed or not at all compressed, whereas less interesting image regions are greatly compressed.

Method for the compressed storage of graphical data

The invention claims a process and device for ensuring the operational readiness of a battery in which the battery is first electrically connected with a testing device, and is then tested with the testing device to determine whether the battery is passivated. If the battery is passivated, a procedure for de-passivation of the battery is performed. If the battery is not passivated, a point in time for the next testing of the battery is scheduled.
