Abstract: An aerosol generation device includes a power system and a controller. The power system includes a first supercapacitor module and a second supercapacitor module. The controller is configured to control a power flow of the first supercapacitor module to power a heater associated with the aerosol generation device, and control a power flow of the second supercapacitor module to charge the first supercapacitor module.

Abstract: An aerosol generation device includes a power system and a controller. The power system includes a first energy storage module and a second energy storage module. The controller is configured to control a pulse width modulated power flow of the power system to a heater associated with the aerosol generation device. The pulse width modulated power flow includes one or more pulse width modulation cycles each having an on period and an off period. The controller is further configured to control the second energy storage module to charge the first energy storage module during the pulse width modulation cycle off period.

Abstract: A radar fill-level measuring device for measuring a fill level of a fill substance in a container using the travel time principle, comprising a circuit board with a sending/receiving system for sending and receiving high-frequency radar waves, wherein the circuit board has at least two openings, a hollow conductor having at least two lateral edge projections, wherein lengths of the at least two projections are greater than the thickness of the circuit board, wherein the at least two projections are led through the at least two openings, so that the at least two projections extend partially out from a second side of the circuit board, a lid, which is secured to parts of the at least two projections, which extend out from the second side of the circuit board, such that the hollow conductor is secured to the circuit board by means of the lid.
