    Abstract: A microfluidics system to maintain alive and control cell cultures such as neuronal cell cultures over an air-liquid interface is arranged to prevent formation of air bubbles and liquid overflows in fully automated 24/7 operation over the mid-long term. A pumping device pushes a liquid through an inlet of the microfluidics channel, then through an area of the microfluidics channel that is under the air-liquid interface, then through an outlet of the microfluidics channel, assisted with geometrical arrangements of the microfluidics channel outlet and optionally inlet placements relative to the porous membranes of the air-liquid interface. The pumping device is programmed with different flow rates, flow directions, and flow durations according to cell culture features and events detected with a computer vision system and/or an electrophysiological signal processing system to automatically adapt the parameters of the pumping device to the current state of the cell culture over the air-liquid interface.

    Abstract: A machine learning system may automatically produce classifier algorithms and configuration parameters by selecting them into a set of predetermined unitary algorithms and associated parametrization values. Multiple digital representations of input object items may be produced by varying the position and orientation of the object to be classified and/or of the sensor to capture a digital representation of the object, and/or by varying a physical environment parameter which changes the digital representation capture of the object by the sensor. A robot arm or a conveyor may vary the object and/or the sensor positions and orientations. The machine learning system may employ genetic programming to facilitate the production of classifiers suitable for the classification of multiple digital representations of input object items. The machine learning system may automatically generate reference template signals as configuration parameters for the unitary algorithms to facilitate the production of classifiers suitable for the classification of multiple digital representations of input object items.
