      We give a very compact account of the overall energy budget of the OUFTI-1 nanosatellite, thereby providing a useful guide for future designs, as well as an explanation of why a nanosatellite can, energetically, survive and do useful tasks in space. Ursi Forum 2012

    • US10208873B2 - Fluidic valveOpen access 

      19 février 2019, Paulus, Nicolas; Frippiat, Cédric; Bomal, Jean-Christian, HE de la Province de Liège
      Brevet
      Hydraulic valves often require actuators or servo motors with dedicated electronics and dedicated electrical power supply. So, you have usually "2 signals" to provide to the actuator/motor : the command signal, which is usually low voltage and/or low current (no real power with it) and the power supply. The actuator/motor requires electronics to handle both signals (and that is expensive, and in ...

    • US11022232B2 - Valve with proportional electromagnetic actuatorOpen access 

      01 juin 2021, Paulus, Nicolas, HE de la Province de Liège
      Brevet
      One limitation of conventional monostable solenoïd actuators, especially the proportional ones (which are not only used in ON/OFF regulation but on whole the stroke window, which require radial and not axial airgaps), is that the force that they can provide is quite limited for a given size of actuator. This is because the mobile part is usually set in the center of the actuator and it saturates ...
