Abstract: Various embodiments are disclosed relating to techniques of controlling a transmitter. In accordance with an example embodiment of the present invention, a maximum level of signal distortion acceptable for a transmission from a transmitter may be determined based on information of operating characteristics of the transmitter and/or the environment in which the transmission is to be made.

Abstract: A MEMS switch comprises a top conductor and at least one first insulator layer having a lateral opening. The at least one first insulator layer hermetically seals the top conductor. At least one second insulator layer is positioned below the at least one first insulator layer such that at least one vacuum gap is formed within the lateral opening between the top conductor and the at least one second insulator layer. The at least one vacuum gap has a thickness in the range 0.5 ? to 100 ? when the top conductor is at rest. The thickness of the at least one vacuum gap varies when the top conductor is moved. The insulator layer has at least one opening that exposes a conducting area of at least one contact conductor within the second insulator layer.

Abstract: A MEMS pressure sensor device comprises a sensor element positioned on top of a carrier and a cavity. The sensor element hermetically seals the cavity. An electrode is coupled to the cavity that forms a pressure transducer together with the sensor element. The cavity is created by a density changing material.

Abstract: A MEMS switch comprises a top cantilevered conductor that moves downwardly. At least one first insulator layer is positioned below the top cantilevered conductor. At least one second insulator layer is positioned below the at least one first insulator layer such that at least one gap is formed between the top cantilevered conductor and the at least one second insulator layer. The gap has a thickness in the range 0.5 ? to 100 ? when the top cantilevered conductor is at rest. The thickness of the at least one gap decreases when the top cantilevered conductor is moved downwardly. At least one contact conductor is positioned below the top cantilevered conductor. The second insulator layer has at least one opening that exposes a conducting area of the at least one contact conductor within the second insulator layer.

Abstract: The invention is related to an apparatus which includes a first generator configured to generate transfer function values of in-phase and quadrature channels. The apparatus further includes a determiner configured to determine compensation coefficients on the basis of the generated transfer function values of in-phase and quadrature channels. The apparatus further includes a second generator configured to generate compensated frequency domain symbols for at least one frequency pair by using the compensation coefficients.
