  • Device for the purpose of influencing the transfer of vibration between two units
    Patent number: 9644698
    Abstract: The invention is a device for influencing transfer of vibration between two units, one is mounted so that it can vibrate and the other is mounted to be damped. A parallel circuit is connected indirectly or directly with both units, which comprises at least one elastically deformable element, with an associated first force path and at least one force generator, providing a second force path, oriented parallel to the first force path and associated with a lever, connected indirectly or directly with the one unit, which lever at one end is rotated about a first axis of rotation oriented orthogonally to both force paths.

  • Activation unit with an actuator
    Patent number: 9441592
    Abstract: An activation unit is disclosed having at least one actuator having a variable length disposed around at least one first axis. The activation unit operatively interacts with an activation element mounted so that it can be bi-directionally deflected along a second axis. The front side of the actuator is indirectly or directly engaged with a first piston, which can be deflected along the first axis in a mechanically positively driven manner. The first piston has a front side facing away from the actuator which axially borders at least regions of a transfer medium on one side. The transfer medium is radially surrounded relative to a first axis by a housing radially to the first axis, and axially borders at least regionally a front side of at least one second piston. The at least second piston can be deflected in a mechanically positively driven manner, and engages the activation element directly or indirectly.

  • Method for the continuous real time tracking of the position of at least one mobile object as well as an associated device
    Patent number: 7139582
    Abstract: In a method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, at least one mobile transmitter module is attached to at least one mobile object and the signals from the at least one module are received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by each transmitter module are electromagnetic waves sent within a frequency band range using time division multiplexing techniques.
