Roger S. Posusta 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).

  • Multi-point distance measurement device
    Patent number: 6759669
    Abstract: A measurement device includes a laser or other light source for producing a light beam, and optics that split the light beam into a plurality of differentiable beam portions, such as a plurality of polarized beams. The optics also direct the differentiable beam portions toward a target to be measured. The measurement device also includes a detection component, such as a plurality of position sensitive detectors, positioned to intercept images created by simultaneous incidence of the differentiable beam portions on the target. The data collected by the detection component is used to calculate measurement data related to the target. When used with a head suspension target, displacement of various regions of the head suspension may be measured relative to a reference region, such as the mounting region of the head suspension.
