Radio frequency identification (RFID) probe for detecting flow of liquid through piping system of e.g. bioreactor, has mark that is provided for positioning RFID layer relative to charging station for charging energy storage unit

摘要

A power supply unit has an energy storage unit that provides energy required for the operation of electrical load. The electrical load and the power supply unit are accommodated within the housing. A mark is provided for positioning the RFID probe layer relative to the charging station for charging the energy storage unit in order to ensure an efficient charging of the energy storage unit. The power supply unit is equipped with an induction coil that induces voltage from outer alternating magnetic field. An independent claim is included for charging station.
