Abstract: A method, device and system for transmitting wireless data are disclosed. In the present disclosure, a local mobile terminal not only may exchange information with a base station, but also may exchange information with other mobile terminals by using a short distance transmission system of the mobile terminals, and transmit, by combining Local Area Network (LAN) communication and Wide Area Network (WAN) communication are combined, data simultaneously via an LAN and a WAN. A target mobile terminal may also receive and send data via the LAN and the WAN. The present disclosure can implement multi-channel transmission of wireless data, thus relieving network load greatly and improving the efficiency of data transmission.

Abstract: An apparatus for dynamically adjusting a power amplifier of a mobile terminal is provided by the present invention, the apparatus includes: a controlling unit, adapted to receive a dynamically varying control signal from a base band chip and control a voltage adjusting unit according to the control signal; the voltage adjusting unit, adapted to dynamically adjust a power supply voltage and a bias voltage of a radio frequency, RF, power amplifying unit under the control of the controlling unit in the case of the mobile terminal being in a transmitting state; and the RF power amplifying unit, adapted to work under the power supply voltage and the bias voltage and to amplify the power of modulated OFDM signal With the present invention, the following problems and disadvantages of the linear power amplifier are overcome: due to the fixed bias and power supply voltage, the efficiency is low and the power consumption is high in the case of a medium or small power output and the linearity does not satisfy the requir

Abstract: A method and apparatus for processing barrier and metals disposed on a substrate in an electrochemical mechanical planarizing system are provided. In certain embodiments a method for electroprocessing a substrate is provided. The method comprises contacting the substrate with the non-conductive surface of a polishing pad assembly, establishing a first electrically conductive path through an electrolyte between an exposed layer of barrier material and a first electrode, establishing a second electrically conductive path through the electrolyte between the exposed layer of barrier material and a second electrode, applying a voltage to the first electrode to cause a voltage drop between the substrate and the second electrode, and removing the barrier material from the substrate.
