Joerg Melcher 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: 9302623
    Abstract: The invention relates to a device for mounting an object to a structure in a vibration-free manner. The device has an elastic arrangement that supports the object at the structure in a stiff manner in the directions of at least two of the total of six translational and rotational degrees of freedom and in a soft manner in the directions of at least one of the total of six translational and rotational degrees of freedom. Main modes of motion of the object in the directions of the rigid support have natural frequencies that are higher than any main mode of motion of the object in any direction of the soft support at least by a factor of ten. The soft support is undamped, and a damping device is provided for any main mode of motion of the object in any direction of the soft support.

  • Publication number: 20130322663
    Abstract: The invention relates to an acoustically active device (1) comprising a substrate (2) that is transparent at least in a viewing region, comprising at least one first electrode (3) that lies on the substrate (2), comprising a piezoelectric layer (4) that lies on the at least one first electrode (3), and comprising at least one second electrode (5) that lies on the piezoelectric layer (4). The at least one first electrode (3) and the at least one second electrode (5) are transparent conductive oxide layers, and the piezoelectric layer (4) is made of a transparent piezoelectric material that extends over the entire surface of the viewing region.

  • Patent number: 6206460
    Abstract: A motor vehicle, particularly a convertible, with a vehicle body to which longitudinally moving struts are assigned and with a supporting frame which includes a longitudinally moving strut, is constructed so that at least one of the struts is constructed so that its length can be varied and has assigned to it an absorbing unit for determining a longitudinal stress, a control element for bringing about a counterforce as well as a control unit for the control element.
