A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.

The present invention relates to the control of power amplifiers in order to enhance the efficiency of the amplifier by tracking the envelope of input signal and applying the same envelope into the drain voltage of a last stage power transistor. This invention can be used in each and every wireless communication transmitter, since there is definitely a power amplifier in the last part of the transmitter before the antenna, and every power amplifier has limited power performance, depending on type of modulation, due to its input-output curve. We are aiming to enhance the power utility of power amplifiers in different applications through introducing a new method and circuit for supplying power into a power amplifier, wherein the power supplied to the drain of the power amplifier is made to follow the envelope of the transmitted RF signal. Embodiments of the invention provide for a drain power supply module to drive the drain of a power amplifier, wherein an array of parallel amplifiers is controlled, depending on the envelope, to switch at different phases.

A clamping element for the transport of a substrate in a predefined transport direction comprises a first and a second leg with a first and second clamping jaw for clamping a substrate. Each of the two clamping jaws has a clamping plate which is movable in transport direction relative to the corresponding leg. A sensor measures the deflection of the first clamping plate relative to the first leg. As soon as the measured deflection exceeds a predefined threshold value, the clamping element is opened.

On measurement of a component A of the amplitude of the oscillations of the tip of a capillary which is clamped to a horn to which ultrasonics can be applied from an ultrasonic transducer, whereby measurement is based on the shading of a light beam by the capillary and whereby the intensity of the light beam is measured by means of an opto-receiver, the capillary is placed at one side of the light beam without it shading the light beam and ultrasonics is applied to it. The capillary is then moved in steps through the light beam whereby, for each of the i&equals;1 to n steps, the direct voltage portion U (y ) and the alternating voltage portion U (y ) of the output signal of the opto-receiver are determined as well as a co-ordinate y whereby the co-ordinate y designates the position of the capillary in relation to a co-ordinate axis y running perpendicularly to the light beam. The amplitude A is then calculated from the values measured.
