The invention relates notably to a method for controlling the transmitter part of a radio transceiver, the transmitter part comprising an IQ modulator, the radio receiver further comprising a receiver part comprising an IQ demodulator, the radio transceiver being dedicated to transmit modulated information signal over an air interface. The air-tight reclosable processed food container, an upper part of which is opened and includes a container body that forms a space with a bottom surface and an container wall and a lid coupled to the container body capable of being opened and closed. The method further includes adjusting, by the controller and based on the comparison, one or more properties of the output to the at least one ionizer to neutralize the charge on the object during a second time period following the first time period, and periodically repeating steps – for successive first and second time periods. The tip-sample interaction is modeled as an impulsive force applied to the cantilever in order to detect the presence of sample. The apparatus is characterized in that for changing the pitch with which the rib is wound on a base tubular element, formed on its turn by the winding coil of the ribbon, at least two twisting bars operated by a crank are used to rotate the supporting elements with a pre-defined angle. The planarizing medium can have a planarizing surface configured to engage the substrate assembly and a backside to face towards the table.
