The invention relates to a digital camera or digital video camera comprising an circular objective, a sensor for acquiring and digitising image information and means for storing the digitised image information, in which all of the image information projected by the objective and contained in an image circle is acquired, disgtised and stored for further processing. Some tests cause the boards to deflect, which can damage component-to-board interfaces or components. Along with the use of the disclosed fault tolerant transmission method of the server, the device manages information transmission of independent systems. Upon reaching a throughput limit for the encryption operations that causes the minimal number of the plurality of encryption processing cores to reach a busy status, the minimal number of the plurality of encryption processing cores for processing the encryption operations is increased. A controller actuates a tool in the tool string in response to a logical combination of outputs from the sensors, where the outputs of the sensors are responsive to the respective pressure signals.
