Abstract: Methods for assessing the result of a surface treatment carried out on a workpiece by particle blasting are disclosed. It is generally common to known automatic methods that they directly determine the covered portion of the surface. Proceeding from the usual definition of the usual 98% degree of coverage as “completely blasted” results in an error in the determination of the corresponding area of 1% to a distortion of the measurement result by 0.98%. In the disclosed method measuring points are identified as not hit by a particle of the particle beam when both a detected surface level is above a level located about a predetermined height threshold value lower than a target level, and a detected gradient falls below a predetermined gradient threshold value.

Abstract: For monitoring a sensor using differential voltage evaluation for detecting a short circuit to ground and/or to supply voltage UB, a first resistor and a second resistor R1, R2 are assigned to the sensor, a sum voltage is determined from voltages UP, UM at terminals of the sensor, the sum voltage is compared to supply voltage UB, a ratio a of determined sum voltage to supply voltage UB is then calculated, and depending on the value for the ratio a, the occurrence of a shunt at the positive terminal and/or negative terminal of the sensor is detected.

Abstract: A pressure control for the program-controlled drive of at least one pressure actuating member influences the hydraulic constellation in a transmission via the pressure (p). The program-controlled drive takes place via changes of states (z; Z0, Z1, Z2, Z3, Z4, Z5, Z6, Z7) from current states (z(t)) to subsequent states (z(t+1)) and that the states (z; Z0, Z1, Z2, Z3, Z4, Z5, Z6, Z7) are all configurable without change of program. A method is provided for the program-controlled drive of at least one pressure actuating member.

Abstract: The present invention relates to pressure control for the program-controlled drive of at least one pressure actuating member in order to influence the hydraulic constellation in a transmission via the pressure (p).
