The invention relates to detecting commissioning errors in a commissioned sensor system, wherein the sensor system comprises a plurality of sensor devices installed so as to cover an area. The sensor devices capture sensor data from the area whilst at least one entity moves through the area. A computer system of the sensor system processes the sensor data to generate a set of location data, which identifies locations traversed by the at least one moving entity. A discrepancy in the set of location data in detected, the discrepancy caused by at least one of the sensor devices having been incorrectly commissioned. Based on this detection, a modification can be made to the sensor system to compensate for or correct the incorrect commissioning of the at least one sensor device.

A novel piezo-driven cell injection system with force feedback overcomes the unsatisfied force interaction between the pipette needle and embryos in conventional position control. By integrating semiconductor strain-gage sensors for detecting the cell penetration force and the micropipette relative position in real time, the developed cell microinjection system features high operation speed, confident success rate, and high survival rate. The effectiveness of the developed cell injection system is experimentally verified by penetrating zebrafish embryos. The injection of 100 embryos are conducted with separate position control and force control. Results indicate that the force control enables a survival rate of 86%, which is higher than the survival rate of 82% produced by the position control in the same control environment. The experimental results quantitatively demonstrate the superiority of force control over conventional position control for the first time.
