Patents by Inventor Bernhard Kistner

Bernhard Kistner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7588378
    Abstract: A camera-support head includes a stator and a rotor that is mounted so that it can be rotated about an inclined axis in relation to the stator. The head also includes a compensation device for compensating a load torque that occurs during the inclination, the device having an energy accumulator which exerts a restoring torque on the rotor during the inclination. In addition, the compensation device has an auxiliary device which influences the transmission of the rotational displacement from the rotor to the energy accumulator and thus also the restoring torque that is exerted on the rotor by the energy accumulator.
    Type: Grant

  • Patent number: 6098978
    Abstract: A resistance device for use in an exercising apparatus having a plurality of resistance elements, a force transmission device and a resistance adjusting device. Through the force transmission device, a user can apply an exercise force to the resistance elements which in general provide a resisting force derived from atmospheric pressure. For adjusting the total resistance, the user may operate the resistance adjusting device to determine which resistance element(s) is(are) enabled to adjust the level of resisting force.
