  • Publication number: 20220009584
    Abstract: A tilt-decoupled steering device of a motorbike includes a handlebar bridge for receiving a motorbike handlebar, a fork bridge for receiving a fork leg, and at least one decoupling device connecting the handlebar bridge to the fork bridge. The handlebar bridge is mounted such that it can rotate about a steering axis and is secured about a tilt axis orthogonal to the steering axis, and the fork bridge is mounted such that it can rotate about the steering axis and about the tilt axis. The decoupling device transfers a steering movement and a steering torque in a steering direction about the steering axis between the handlebar bridge and the fork bridge, and compensates for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge.

  • Publication number: 20210316393
    Abstract: In a method for guiding a cutting head in relation to a material, a position and a speed of the cutting head are set by means of a drive unit depending on a desired position value and a desired speed value established by an interpolator unit, a control signal for the drive unit is determined, a distance between the cutting head and the material is determined with a distance sensor, and a corresponding distance signal is provided. The distance signal is compared with a predetermined comparison distance to yield a distance-control signal, and the control signal for the drive unit is additionally determined dependent upon a distance-control signal. The comparison distance is subtracted from the distance signal and the difference is superimposed on the actual position signal, which is delayed by a first time period, wherefrom the distance-control signal is determined.

  • Patent number: 10481578
    Abstract: A drivetrain for linear movement of a machine component along a linear guide of a machine includes a motor with a motor-measuring system. A length-measuring system is assigned to the linear guide for determining a position of the machine component. To determine rigidity of the drivetrain, a constant acceleration for the machine component is predetermined by a numerical controller for performing closed-loop control of the movement of the machine component. The numerical controller determines a difference between a position of the machine component derived from the motor-measuring system and a position of the machine component measured at the same time by the length-measuring system during the acceleration phase, and the difference is assigned to the acceleration or to a force required for the acceleration and storage in the numerical controller of the pair of values established in this way and/or of a rigidity value emanating from the pair of values.

  • Publication number: 20110178529
    Abstract: A minimally invasive method of introducing an interface element to interface with laryngeal structures of a subject includes forming a subperichondral tunnel on an outside of a cricoid cartilage arch and through the cricoid cartilage arch towards a cricothyroid joint to form an insertion route. The method also includes inserting a hollow needle into the insertion route to a posterior space of a cricoid cartilage plate of the subject, positioning at least one interface element along the insertion route for interfacing with the laryngeal structures of the subject, and retracting the hollow needle back along the insertion route.

  • Patent number: 7156224
    Abstract: A circulating mechanism includes a moving member, e.g. a chain or a belt, which travels along a circulating path and is looped about at least one deflecting member for reversing a travel direction of the moving member. Disposed in a section of the circulating path is a guide assembly for guiding the moving member. A magnetic field generating device is provided for applying a magnetic force upon the moving member at least in an area of the guide assembly so as to draw the moving member against the guide assembly and thereby enhance the travel behavior of the moving member.

  • Patent number: 7152503
    Abstract: A device for compensating a torque produced on a movable axle in a machine tool or production machine by a gyrostatic effect includes a rotating useful machine system attached to the movable axle and producing a useful angular momentum, and a rotating machine counter-system attached to the axle and producing a counter angular momentum. The magnitude of the counter angular momentum is substantially identical to the magnitude of the useful angular momentum. The useful torque produced by a movement of the rotating useful machine system through a temporal change of the useful angular momentum is at least partially compensated by a counter-torque produced by a temporal change of the counter angular momentum. This arrangement represents a simple device for compensating a torque produced by the gyrostatic effect on a movable axle of machine tolls and production machines.
