An electronic control device is described for controlling an automatic transmission, having a control circuit an integrated plug connector and an integrated position sensor in a housing, the position sensor including a stator and a rotor. The disclosed method and apparatus utilize a low complexity algorithm that performs automatic gain control to achieve greater speed of convergence of the echo canceller and an increased ability to distinguish between near-end speech and echo through the use of specific automatic gain control. Subsequently, another image capture is automatically triggered when the same subject is detected within the camera’s field of view. The filter can modulate an incident radiation flux. The objects selected and localised in this way are then sequentially positioned exactly by a displacement, the coordinates of which are controlled by the image calculator, between the substrate and a separation actuator and are spatially separated from the substrate by the separation actuator. Such a configuration allows a small semiconductor chip to be produced in a cost-effective manner, using minimal resources and the chip can be enhanced by any number of modules, without modifying the characteristics of the system, in which it is contained.
