Patents by Inventor Yehuda Borenstein

Yehuda Borenstein 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: 8736805
    Abstract: A mirror system, comprising a spectrally selective liquid crystal reflective assembly, designed and constructed to substantially absorb or transmit light at wavelengths corresponding to mesopic conditions, while reflecting light at other wavelengths. In one embodiment, the reflectance level of the mirror system is altered in response to a voltage applied across the selective liquid crystal reflective assembly.
    Type: Grant

  • Patent number: 7733464
    Abstract: A vehicle mounted imaging system and method, enabling selective imaging of objects in a low-visibility environment. The system includes a light source providing non-visible light pulses and a camera having an image intensifier enabled to gate selected received images. The light source may be a laser generator, which may be enabled to generate a pulse width related to the depth of a field to be imaged. The gated image intensifier may determine gating time spans according to the depth of a field to be imaged.

  • Publication number: 20080205076
    Abstract: An automatic dimming mirror system is disclosed. The mirror system comprises a liquid crystal reflective assembly being responsive to voltage applied across the assembly, and an electronic circuitry for varying a level of the voltage at a predetermined rate thereby to a alter a reflectance level of the assembly at the predetermined rate.

  • Patent number: 7319219
    Abstract: The application disclose a system for handling light that is amenable for intensification by an Image Intensifier and a method for handling the same, wherein the system includes light regulating means for regulating light intensity of the transmissive MEMS (Micro Electro Mechanical System) type in order to prevent light rays emanating from intensely bright light areas from reaching the input plane of the image intensifier, or (instead of using said transmissive MEMS), the system implement light regulating means of the reflective MEMS type and while utilizing the reflective MEMS, the image intensifier is driven to operate in a gating mode, in order to time the light intensifying action of the intensifier to start upon the specific time slot that was essentially completed, of deflecting the light rays emanating from intensely bright light areas away from the input plane of said image intensifier.
