  • Patent number: 11726077
    Abstract: A method is provided for calibrating impedance-spectroscopic biomass sensors that are embodied to detect information regarding the quantity and/or size of living cells in a biomass by means of an electric field having a periodically changing field direction A calibration suspension encompasses an electrically conductive viscously flowable or viscoelastic carrier substance and electrically conductive solid particles and/or solid semiconductor particles received therein. An electric field is generated having a periodically changing field direction, which acts on the calibration suspension. At least one permittivity value is detected, respectively representing a permittivity of the calibration suspension, in a context of at least two electric fields having different field direction change frequencies. A difference value is ascertained that represents a difference between the detected permittivity values. The difference value is compared with a reference value associated with the calibration suspension.

  • Publication number: 20230251329
    Abstract: A method includes performing a test for transformer rectifier unit (TRU) backfeed protection by removing AC power supplied to the TRU but keeping the TRU contactor closed for a first predetermined span of time. The method includes observing the TRU for a second predetermined span of time.

  • Patent number: 11713790
    Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; and spring having a first end coupled to the input shaft and a second end coupled with the output shaft. In a low torque mode, when the input shaft is rotated the spring is compressed by a low amount and transmits a force to drive rotation of the output shaft, whereas in a high torque mode the spring is compressed by a high amount such that the input shaft rotates relative to the output shaft. This relative rotation moves or urges an engagement member so as to either: disconnect the input shaft from the output shaft; or engage a housing to prevent or inhibit rotation of the input shaft relative to the housing.
