Abstract: A method for classifying a specific pipetting procedure of a laboratory automation device comprises: determining a plurality of pressure curves of a plurality of pipetting procedures, which are equivalent to the specific pipetting procedure; determining a median curve from the plurality of pressure curves, wherein for each time point of the median curve, a median value of the values of the plurality of pressure curves at this time point is calculated; determining a median curve range containing the median curve; controlling the laboratory automation device to perform the specific pipetting procedure and measuring a specific pressure curve during the specific pipetting procedure; determining a deviation value of the specific pressure curve with respect to the median curve range, wherein the deviation value is indicative of the specific pressure curve leaving the median range; and classifying the specific pipetting procedure as erroneous, when the deviation value is greater than a threshold.

Abstract: A method for teaching parameters for a door sensor for monitoring a monitoring field in front of the door leaf of a door, including: using an at least 2-axis rotation angle encoder having at least 1-axis inclination in relation to the door leaf; opening the door leaf of the closed door; detecting the rotation of the two axes of the rotation angle encoder during opening; ascertaining the direction of rotation of the two axes on the basis of the rotation thereof; ascertaining the side of the door on which the door sensor is installed on the door leaf on the basis of the direction of rotation of the two axes; and storing the side of the door in a memory unit.

Abstract: Door sensor (30) for installation on the door leaf (21) of a swing or revolving door (20), having a 3D image sensor for monitoring a monitoring field (30) in front of the door leaf, having a rotation angle encoder for detecting the rotation angle of the door leaf, wherein the door sensor has a common support that connects the 3D image sensor to the rotation angle encoder.
