In a method for storing and providing medical image data in a distributed, computer-based system of a clinical facility comprising multiple satellites, wherein a satellite has at least one modality, an image administration server and at least one local database, and wherein the clinical facility also has a central database for the administration of the stored image data and a central long-term storage for long-term storage, the image data are acquired at the modality, the image data include metadata and pixel data, partial metadata in the metadata of the acquired image data are marked, at least the metadata of the image data acquired are locally stored at the respective satellites, the image data of the image data acquired at the respective satellites are centrally stored in the central long-term storage, all metadata stored in the local database in the central database are completely, centrally replicated, and the marked partial metadata of the image data from the central database are partially, automatically replicated at respective local databases of one, multiple or all satellites in order to be able to provide these image data at the satellites.

Method, computer-readable medium, and system for storing, allocating and retrieving medical image data in a distributed computerized system of a clinical facility

A method for controlling an internal combustion engine with at least two cylinders in the case of irregular running caused by combustion problems has the following steps: measurement of a segment time of a first cylinder during a first time interval Tin the sequence of operations of the internal combustion engine, with a corresponding first signal being transmitted as a first actual value to a control, sensing of pressure fluctuations in the second cylinder during a second time interval Tin the sequence of operations of the internal combustion engine, with a corresponding second signal being transmitted as a second actual value to a control and changing of operating parameters of the at least one cylinder by means of the control on the basis of the first and second signal, when the first and the second actual value each deviate from setpoint values stored in the control.

The total ignition angle ZW(z) of each cylinder z is composed of cylinder-selective values basic ignition angle GZ(z) &lcub;determined by engine speed n and load L&rcub;, knock adjustment angle KNK(z), in addition to a first adaptation value AD,(z) and a second adaptation value AD,common to all cylinders. AD,(z) is increased when KNK(z) is greater than a threshold DEC and is reduced when KNK(z) is lower than a threshold INC. The second adaptation value AD,is formed as a function of the average value {overscore (AD,+L )} of the adaptation values of all cylinders.

A method for monitoring the operation of sensors in an internal combustion engine includes providing reference values from output signals from a sensor. A sliding average (comparison value) is calculated from a relatively large number of reference values. The operation of the sensor is diagnosed as a function of the amplitude distribution of the reference values about the comparison value. If a malfunction is found, a fault message is transmitted to the driver and reversionary running of the internal combustion engine is started. An electric controller operating in accordance with the sensor is also provided.
