Abstract: A system for determining a change of saturation of an adsorbent susceptible to adsorption of species in an adsorption chamber, the system comprising: an adsorbent-holding-ferrite-material cage; a cage holder configured to hold the cage within the adsorption chamber such that the movement of the cage at least in a first axis is restricted to a smaller extent than in a second axis; an exciter comprising a coil arranged at the cage, wherein the coil is connected to a voltage generator and the exciter is configured to induce eddy currents within the cage resulting in oscillation of the cage in the first axis; a spectrum analyzer connected to the coil and configured to analyze the voltage within the coil and determine its frequency response; and a saturation detector configured to determine the change of saturation based on the change of the frequency response determined by the spectrum analyzer.

Abstract: A flow control system for controlling flow in a system of valves connected to a splitter wherein a pressurized fluid is supplied to the splitter by a motor-driven pressurizer, the flow control system comprising: a plurality of flow sensors connected individually at an output of one of the valves to measure output flow from connected valve; a plurality of flow controllers connected individually to one of the valves for outputting a control signal controlling an opening angle of that particular valve in response to an output from a flow sensor connected at the output of that particular valve and an outlet setpoint provided for that particular valve; a main pressure sensor for measuring pressure of fluid output from the pressurizer; a main flow controller for adjusting operation of the motor driving the pressurizer; and a main system controller configured to set the main pressure setpoint based on the control signals.

Abstract: A battery stack comprising: a plurality of batteries (40) arranged adjacently to each other; and bus bars (10) having contact feet (12, 14) at their ends, for connecting the bus bar (10) to poles of the batteries (40); wherein each bus bar (10) connects two poles of two adjacent batteries (40), such as the bus bars (10) form electrical connection between the batteries (40) within the battery stack. At least one battery has connected thereto a battery management system (BMS) (30), for controlling and local optimization of battery charging and discharging parameters, coupled via a contact area (31) to one of its poles (41) such that the contact area (31) of the battery management system (30) is located between the pole (41) of the battery and the contact foot (12) of the bus bar (10), and wherein the BMS (30) comprises a temperature sensor (33) thermally coupled with the contact area (31).
