A safety controller for controlling an automated installation which has a plurality of sensors and a plurality of actuators, comprises a control unit to which a plurality of control input signals are supplied by the sensors. Other embodiments are described and claimed. An apparatus and method for generating such a volatilized liquid, as well as the control and methods of heating, are disclosed as an analytical tool useful for experimental use, a tool useful for production of commercial products or an inhaler device. Such a surface layer may be applied easily and shows a significantly improved behavior regarding the machining thereof, without negatively influencing other important characteristics of the layer material, like wear resistance and coefficient of friction vis–vis the material of the piston rings. A preferred embodiment of the RF transceiver IC includes two distinct PA circuits, two distinct receive signal amplifier circuits, and a four-way antenna switch to selectably couple a single antenna connection to any one of the four circuits. The method includes forming a flexible printed circuit on a polymeric film, attaching thin air data sensor to the printed circuit and attaching a flexible substrate to form a conformal air data sensor.
