Ralf Weise 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).

  • APPARATUS AND METHOD FOR OPTICAL INSPECTING THREE OR MORE SIDES OF A COMPONENT
    Publication number: 20240230552
    Abstract: The inventions describes an apparatus for inspection of a component comprising an adjustable optical element for image detection in two steps—with focus on the second (or bottom) face of the component and with a focus on the sides. This allows the degree of image degradation in one or more of the images to be reduced.

  • Eye position registering and tracking
    Patent number: 10213104
    Abstract: Embodiments of the invention refer to a system for registering and tracking the position of a person's eye, in particular for refractive ophthalmic surgery. According to embodiments, the system is structured such that eye images containing at least the iris and the pupil of the eye are made at a first wavelength of light and that eye images containing scleral blood vessels are made at a different second wavelength of light. The invention furthermore refers to a corresponding method for registering and tracking the position of a person's eye.

  • Apparatus for determination and decrease of dynamic positioning errors of an ablating laser during refractive laser surgery
    Patent number: 8187258
    Abstract: The above described apparatus and methods provide the possibility to reduce or even eliminate the effects of delay between image acquisition and laser ablation. Thus this will lead to less positioning errors and therefore to better ablation results in laser refractive surgery. The importance of this invention will increase with decreasing ablating beam diameter. The use of synchronization leads to shorter delay times. Hence it follows that the duration of the whole treatment decreases as well.
