  • Patent number: 9296399
    Abstract: A method controls a compressed-air braking device of a rail vehicle in the case of automatic, quick, or emergency braking, said compressed-air braking device having a controlled electropneumatic braking device having brake pressure control, an uncontrolled brake pressure control device for producing an uncontrolled brake pressure, and at least one pneumatic brake actuator. In response to a signal to trigger automatic, quick, or emergency braking, the controlled electropneumatic braking device and the uncontrolled brake pressure control device are activated simultaneously and a first value for the brake pressure produced by the controlled electropneumatic braking device or a first value for a pilot control pressure representing the brake pressure and a second value for the brake pressure produced by the uncontrolled brake pressure control device or a second value for a pilot control pressure representing the brake pressure are compared with each other.

  • Patent number: 8672963
    Abstract: The present invention relates to a lancet device, by which a lancet can be displaced along a piercing path for generating a piercing wound in a skin surface, in particular to obtain bodily fluid for diagnostic purposes, comprising a lancet drive having drive means to generate a drive force for a piercing movement of the lancet along the piercing path in the direction toward the skin surface. According to the present invention, the lancet drive comprises a magnet, by which a magnetic retention force oriented opposite to the drive force may be generated, and the lancet drive also comprises triggering means, by which the retention force may be reduced enough that the lancet is accelerated in the direction toward the skin surface under the effect of the drive force generated by the drive means.
