Eric G. Gesner 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: 10776950
    Abstract: An alignment system for an imaging sensor of a coordinate measuring machine incorporates a reference surface associated with a stage of the measuring machine but instead of imaging the reference surface as a location marker, the reference surface is incorporated into a combined imaging system together with the imaging sensor for imaging a feature associated with the imaging sensor. The imaged feature can be an internal part of the imaging sensor, such as an internal aperture, or an external feature in a fixed relationship with the imaging sensor, such as a lens hood.
    Type: Grant

  • Patent number: 7859649
    Abstract: An adapter and method for through the lens (TTL) laser range sensor probes enables use of a TTL probe of a given exit pupil size to be used with a shared objective lens requiring a entrance pupil size, as entered from the laser range sensor, that is different from the TTL probe exit pupil size. Embodiments of the adapter include optics, such as a first lens and a resolving second lens that expand or contract the TTL laser radiation depending on whether the first lens is a diverging, a negative focal length lens, or a converging, positive focal length lens, and the second lens is converging or diverging, respectively, in a Galilean arrangement. Embodiments also provide a Keplerian arrangement, can function with non-collimated radiation, and can include mirrors to yield a more compact adapter. Additional embodiments include at least one adjustable lens element between the first and second lenses, the at least one adjustable lens element being connected to an actuator for movement along the optical path.

  • Patent number: 7808617
    Abstract: A distance detecting arrangement employs at least two sensors having different ranges and resolutions of operation. Embodiments disclosed contemplate at least four modes of operation. In a first mode, only one sensor is employed. In a second mode, a longer range and lower resolution sensor is employed until a threshold value of distance is reached, at which point a shorter range and higher resolution sensor is employed. In a third mode, both the longer range and shorter range sensors are employed simultaneously. In a fourth mode, a low resolution profile is used to rescan the object with the high resolution sensor to provide a high resolution profile measurement. Embodiments facilitate the method disclosed by including a beam redirecting apparatus and preferably include a servo position system that can move the sensors and the object relative to each other.
