    摘要： It is therefore the object of the present invention to disclose a device for power calibration of an oscillator in the high-frequency range, which has a reduced number of components and/or has less-expensive components. A method for power calibration of an oscillator is also to be disclosed, which eliminates the disadvantages of the known methods, that is, determining the output power of the oscillator via an additional, expensive component. To that end, the input (31) of the control module (40) is embodied as electrically connectable to the HF switch (comprising (22) and (24)) and the output (34) of the control module (40) is embodied as electrically connectable to the HF switch and/or to the amplifier. If the HF switch is then not acted upon by an input signal (pulse or direct voltage), but instead if the voltage is measured at the control input (30) of the HF switch, then the required controlled variable (the HF output power) is achieved, since the PIN diodes of the HF switch rectify the apply HF power and generate a proportional direct voltage.

    摘要： The invention relates to a system for injecting a liquid into a body, comprising an implantable chamber disposed under the skin and an injection device including: a base bearing an injection needle having a free end that is intended to be inserted into the chamber; an injection conduit connected to the needle; means for extracting the needle; means that can be actuated to generate excess pressure in the injection conduit; synchronization means between the extraction means and the generation means for actuating the generation means during a needle extraction phase. The synchronization means can essentially only actuate the generation means when the free end of the needle is located in the chamber during the needle extraction phase.
