Patents by Inventor Hubert Lettenbauer

Hubert Lettenbauer 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).

  • Method and device for determining actual dimensional properties of a measured object
    Patent number: 10767988
    Abstract: A CMM has a measuring head for recording measurement values associated with an object having a plurality of geometric elements. Defined geometric elements are selected from the plurality of geometric elements and test features relating to the defined geometric elements are determined depending on demand data provided for the geometric elements. Initially, a first measurement sequence including first control commands for controlling the measuring head are determined depending on the test features. The first measurement sequence is modified before the individual measurement values are recorded in order to obtain a second measurement sequence with second control commands, which differ from the first control commands.
    Type: Grant

  • Method and device for identifying material boundaries of a test object
    Patent number: 8045806
    Abstract: A method and a device determine material interfaces in a test object. The novel method generates three-dimensional image data of the test object or uses already existing three-dimensional image data of the test object. Image values of the image data are, or were, obtained by invasive radiation. An evaluation line for evaluating the image data relative to the test object is determined, a location of a material interface of the test object is determined by evaluating the image data of image values along the evaluation line so that the value of the first partial derivative of the image values in the direction of the evaluation line has a local maximum at the location of the material interface.
