  • Publication number: 20190137580
    Abstract: A circuit arrangement for an MRT system and a method for operating an MRT system are disclosed. The circuit arrangement includes a gradient amplifier having a switch-mode output stage, a regulator device, and a modulator connected therebetween in the circuit. To ensure patient safety, a control path is integrated into a drive path of the circuit arrangement or the MRT system provided for driving a gradient coil, the gradient coil being connected to an output of the switch-mode output stage. The control path includes a limiter stage connected downstream of the regulator device, the modulator, the switch-mode output stage and its supply voltage. The limiter stage is connected in the circuit between the regulator device and an input of the modulator, to limit a control signal output by the regulator device and limit the voltage for the gradient coil provided by the switch-mode output stage at its output.

  • Patent number: 10024433
    Abstract: A crankshaft seal flange has a support made at least partially of a plastic material. The support has a passage with an inner wall. The support has at least one dynamic seal that extends about a circumference of the inner wall of the passage. At least one sensor is provided that detects crankshaft rotary speed and crankshaft position. The at least one sensor encompasses an electronic component group that is integrated into the plastic material of the support.
