Hansjoerg Petschko 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 for determining position, laser beam detector and detector-reflector device for a system for determining position
    Patent number: 8259311
    Abstract: The invention relates to a system for determining a position by emitting a first laser beam (7) by a laser source (6) positioned in a reference system onto a detector (1) and simultaneously detecting the first laser beam (7) by the detector (1), thus defining an emission direction of the laser source (7). The detector (1) has a segmented detection area comprising a plurality of discrete partial detection areas (17), each having a defined partial detection direction and at least two partial detection directions thereof being different. When detecting the first laser beam (7), an impingement point (9) of the first laser beam (7) on the detector (1) is detected by means of at least one partial detection area (17), and when determining the incidence direction (10), said direction is derived from the at least one partial detection direction. The location of the detector (1) relative to the laser source (6) and the reference system is then determined using the emission direction and the incidence direction (10).
