A method of malicious network activity detection. The main property utilized by the present invention for maintaining cell-coverage pattern control, when radiating information in two simultaneous beams, is to use orthogonal polarization states for the two beams. The monitoring apparatus comprises a navigation device that can determine the vehicles position, a memory device, and a telecommunication device. In the first process, the lighting device obtains a measurement indicative of the impedance by supplying power to the first impedance device via the second power supply terminal while prohibiting output of DC power for lighting, and determine an operating condition based on the measurement. The bottom of the container has a central elevation projecting inwards and leaving an annular space between the sidewall of the container and the elevation, the applicator head extending into this annular space when the closing device is closing the opening of the container.
