  • Patent number: 10464416
    Abstract: A method for operating a drive train for a motor vehicle, with at least one primary drive axle and at least one secondary drive axle, which are operatively connected to each other via a clutch to an adjustable transmission torque. At the same time it is provided that a vibration amplitude of a vibration of the drive train is determined and in a damping operation type of the drive train, the transmission torque is determined from the vibration amplitude and adjusted on the clutch.

  • Patent number: 10358030
    Abstract: A method for operating a drivetrain for a motor vehicle, said method includes: reducing a transmission torque transmitted between a primary drive axle operatively connected with a secondary drive axle of the motor vehicle via a clutch configured to allow adjustment of the transmission torque when determining at the secondary drive axle a wheel slip which exceeds a defined slip threshold value.

  • Patent number: 9314611
    Abstract: A stimulation device for the application of a transcutaneous electric stimulation stimulus onto the surface of a section of the human ear, which includes a holding element an electrode arranged in a electrode carrier. The holding element has a linear guide. A resting part is arranged at the holding element. The holding rod has a first axis and runs from a first position, which adjoins to the linear guide, to a second position, which adjoins to the electrode carrier. The resting part defines a first plane with a resting area at the ear, on which area a second axis is arranged perpendicular. The first axis and the second axis span a middle plane. The holding rod lies at the first position in the middle plane and departs from the middle plane from the run from the first position to the second position in a first rod section until a reversal point.

  • Patent number: 8751020
    Abstract: The invention relates to a electrode arrangement (1) for the application of a transcutaneous electric stimulation stimulus onto the surface of a section of the human ear (2), which comprises a holding element (3) to be arranged at or in the ear (2) as well as at least on electrode (4, 5), which electrode (4, 5) is arranged in an electrode carrier (6). To allow a simple and comfortable application of the electrode arrangement at the ear and to influence the hearing during wearing of the electrode arrangement as little as possible the invention suggests that the holding element (3) comprises a linear guide (7) in which a holding bar (8) is arranged linear movably in the direction of a longitudinal axis (L) of the holding element (3), wherein the electrode carrier (6) is arranged at the holding bar (8).

  • Patent number: 8688239
    Abstract: The invention relates to an electrode arrangement for applying of a transcutaneous electrical stimulation stimulus onto the surface of a section of the human ear, which comprises a holding element to be attached at or in the ear as well as at least one electrode, which electrode is arranged in or at an electrode carrier, wherein the holding element comprises a linear guide in which a supporting rod is arranged linear movable in the direction of a longitudinal axis (L) of the holding element and wherein the electrode carrier is arranged at the supporting rod. To obtain an improved transcutaneous stimulation the invention proposes that the electrode carrier comprises at least one carrier section on which the electrode is arranged, wherein the electrode comprises at least one cylindrical and/or spherical segment shaped and/or conical surface section.

  • Patent number: 8666502
    Abstract: The invention relates to an electrode arrangement for applying of a transcutaneous electrical stimulation stimulus onto the surface of the human ear. A holding element is attached to the ear. At least one electrode is arranged on an electrode carrier and the electrode carrier is arranged on a supporting rod. The holding element has a linear guide in which the supporting rod is arranged linear movable in the direction of a longitudinal axis (L) of the holding element. A latching mean is arranged between the linear guide and the supporting rod, so that the supporting rod can be latched relatively to the linear guide along the longitudinal axis (L) in predetermined relative positions. The latching means has a rack shaped contour on the supporting rod which extends into the direction of the longitudinal axis (L) of the holding element.

  • Publication number: 20130231729
    Abstract: The electrode arrangement applies a transcutaneous electrical stimulation stimulus to the surface of a section of the human ear. A holding element attaches at or in the ear. At least one electrode is held by an electrode carrier. The holding element has a linear guide on a supporting rod which is linear movable in the direction of a longitudinal axis of the holding element. The electrode carrier is arranged at the supporting rod. To improve the handling of the electrode arrangement latching means are between the linear guide and the supporting rod, so that the supporting rod can be latched relatively to the linear guide along the longitudinal axis in predetermined relative positions. The latching means is a rack shaped contour, which is on the supporting rod and which extends into the direction of the longitudinal axis of the holding element.
