An imaging device is described having an electro-mechanical image stabilization system capable of removing the effect on a generated image of vibration and angular movement of the device. The titanium boronitride is used as conductive material in the testing and fabrication of integrated circuits. A method of cooling a battery module is also described. A deflector is mountable on a front portion of the boat. The elevator cage has on the cage roof a region vulnerable to spray water, and this region vulnerable to spray water is covered by an element having a surface structure of such a kind that extinguishing water falling on the element in the event of fire is substantially prevented from spraying in the direction of the at least one support means. Optionally, a plurality of the separated subcarriers may be combined to reconstruct at least one transmitted single-carrier signal from a plurality of frequency components.
