  • Patent number: 10923909
    Abstract: A bidirectional switch and a method of the bidirectional switch including, a first enhancement mode n-channel metal oxide semiconductor field effect transistor (n-MOSFET) and a second n-MOSFET electrically connected in a common source configuration. The emitter of an insulated gate bipolar transistor (IGBT) is further electrically connected to the common sources of the n-MOSFET. A control board regulates a first operation of the IGBT and an operation of the first field effect transistor. The control board additionally receives at least one measured characteristic, from a sensor and determines the measured characteristic is below a predetermined threshold. The control board then regulates an operation of the second field effect transistor and a second operation of the IGBT.

  • Patent number: 9689463
    Abstract: A roller (20) for a pendulum mass (4, 5, 6) of a centrifugal force pendulum (1), including a rolling section (42), a first maintaining section (26) and a second maintaining section (27). The maintaining sections have a larger diameter than the rolling section, and the roller (20) has a width (44) which is smaller or the same size as the first depth (9) of the centrifugal force pendulum. Due to roller (20), a centrifugal force pendulum can be constructed for particularly flat couplings. In particular, the total weight of the friction clutch is reduced and the mounting is simplified.

  • Publication number: 20150224497
    Abstract: A sample collection tube is disclosed for collecting a body fluid sample. The tube includes a closure arranged at an open end to close the open end and a partially evacuated inner space. The closure also includes a base portion connected to the sidewall and a cap portion coupled to the base portion, where the cap portion has an elastomeric material that is pierceable from outside of the tube for collecting a sample into the partially evacuated inner space and where the cap portion can be pivotable with respect to the sidewall such as to make the inner space accessible for withdrawing an aliquot of the sample. Alternatively, the cap portion can be separable from the base portion to make the inner space accessible and the base portion can include a self-resealable valve adapted to allow access of a pipetting unit into the inner space when the cap portion is separated and adapted to re-seal after withdrawal of the pipetting unit. Also disclosed is a work cell for handling sample collection tubes.
