Patent number: 9490754Abstract: 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.Type: GrantFiled: September 10, 2013Date of Patent: November 8, 2016Assignee: INNOVARADIO SAInventors: Amir Hooshang Farahani Samani, Alexander Greber, Jeyran Hezaveh, Ali Asghar Talebi

Publication number: 20090314767Abstract: An electrical heating element, in particular for a hot-wedge film welding device, having two electrodes and a heating resistor arranged between the electrodes such that an application of an electrical voltage to the electrodes results in heat being produced along the length of the heating resistor. The heating resistor is designed to correspond to the shape of a heating wedge of a film welding machine, such that it can replace the heating cartridge and the hot wedge of a conventional film welding device. It is preferably produced from a conductive ceramic material and is distinguished by uniform heat distribution, good thermal conductivity and resistance to wear, as well as by excellent corrosion resistance.Type: ApplicationFiled: January 25, 2007Publication date: December 24, 2009Inventors: Jie-Wei Chen, Alexander Greber

Patent number: 6993986Abstract: 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.Type: GrantFiled: June 24, 2003Date of Patent: February 7, 2006Assignee: ESEC Trading SAInventors: Peter Hess, Raphael Bernhardsgruetter, Alexander Greber, Hansjörg Gujer, Nicolino Onda

Patent number: 6691574Abstract: On measurement of a component Ay 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=1 to n steps, the direct voltage portion UDC(yi) and the alternating voltage portion UAC(yi) of the output signal of the opto-receiver are determined as well as a co-ordinate yi whereby the co-ordinate yi designates the position of the capillary in relation to a co-ordinate axis y running perpendicularly to the light beam. The amplitude Ay is then calculated from the values measured.Type: GrantFiled: February 24, 2003Date of Patent: February 17, 2004Assignee: ESEC Trading SAInventors: Peter Hess, Alexander Greber, Markus Michler, Nicolino Onda
