  • Patent 1

    Inventors: A. Shpunt, J. Garcia and Z. Zalevsky, and A. Maziels.
    Title: Method and System for Object Reconstruction.
    Application Patent number: US 20100177164 A1.
    Country: US.
    Date of priority: 2006.
    Status: Licensed IP. In addition with Patent (1), this patent was made in collaboration with PrimeSense Israeli company. They are part of the patent portfolio that is included in the Kinect device, licensed to Microsoft for Xbox 360.
    Brief description: This patent presents a system and method for use in 3D object reconstruction. The system comprises an illuminating unit, and an imaging unit. The illuminating unit comprises a coherent light source and a generator of a random speckle pattern accommodated in the optical path of illuminating light propagating from the light source towards an object, thereby projecting onto the object a coherent random speckle pattern. The imaging unit is configured for detecting a light response of an illuminated region and generating image data. The image data is indicative of the object with the projected speckles pattern and thus indicative of a shift of the pattern in the image of the object relative to a reference image of said pattern. This enables real-time reconstruction of a 3D map of the object.
  • Patent 2

    Inventors: Javier Garcia and Zeev Zalevsky.
    Title: Range mapping using speckle decorrelation.
    Patent number: US 7,433,024 B2.
    Country: US.
    Date of priority: 2008.
    Status: Licensed IP. In addition with Patent (3), this patent was made in collaboration with PrimeSense Israeli company. They are part of the patent portfolio that is included in the Kinect device, licensed to Microsoft for Xbox 360.
    Brief description: This patent describes a method for 3D mapping that includes projecting a set of primary speckle pattern dots from an illumination assembly into a target region (3D volume). Then, a plurality of reference images of the primary speckle pattern are captured at different respective distances from the illumination assembly in the target region. The test image of the primary speckle pattern dots that are projected onto a surface of a 3D object in the target region is captured and compared to the reference images so as to identify a reference image in which the primary speckle patterns most closely matches the primary speckle patterns in the test image. As consequence, the location of the object is estimated based on a distance of the identified reference image from the illumination assembly.
  • Patent 3

    Inventors: Zeev Zalevsky and Javier Garcia.
    Title: Motion detection system and method
    Israeli Patent Application No. 184868 (July 2007); WO/2009/013738
    International Application No PCT/IL2008/001008 (July 2008).
    Status: Licensed IP. Has been licensed for far east countries in Homeland Security applications through a contract held by Bar Ilan University and University of Valencia.
    Brief description: The ability of dynamic extraction of remote sounds is very appealing. In this patent, an optical approach allowing the extraction and the separation of remote sound sources is presented. The approach is very modular and it does not apply any constraints regarding the relative position of the sound sources and the detection device. The optical setup doing the detection is very simple and versatile. The principle is to observe the movement of the secondary speckle patterns that are generated on top of the target when it is illuminated by a spot of laser beam. Proper adaption of the imaging optics allows following the temporal trajectories of those speckles and extracting the sound signals out of the processed trajectory. Various sound sources are imaged in different spatial pixels and thus blind source separation becomes a very simple task.

  • US Patent application 1

    Inventors: Javier GarcĂ­a and Alexander Shpunt.
    Title: Depth ranging with Moiré patterns.
    US Application Number: 20100201811.
    Publication date: 12-August-2010.
    Brief description: In this application, a method for 3D mapping of an object, including projecting with a projector a set of fringes on the object and capturing an image of the object in a camera, is patented. The method further includes processing the captured image so as to detect a Moiré pattern associated with the object and so as to extract depth information from the Moiré pattern, and configuring the projector and the camera so that a locally unambiguous characteristic of the Moiré pattern is related to a depth of the object.
  • US Patent application 2

    Inventors: Zeev Zalevsky, Yevgeny Beiderman, Javier Garcia, and Vicente Mico.
    Title: Optical Sensor for Remote Estimation of Glucose Concentration in Blood.
    US Application Number: 61/457,202.
    Filing date: 28-Jan-2011.
    Brief description: This patent describes the application of the previously presented technology (see Patent 3 of the present list) and its capability to monitor glucose concentration in blood stream. The technique is based on the tracking of temporal changes of reflected secondary speckle produced in human skin (wrist) when being illuminated by a laser beam. A temporal change in skin’s vibration profile generated due to blood pulsation is analyzed for estimating the glucose concentration.
  • US Patent application 3

    Margalit, and Revital Barelly.
    Title: Method and system for non-invasively monitoring biological or biochemical parameters of individual.
    US Application Number: PCT/IL2012/050029.
    Filing date: 02-August-2012.
    Status: Licensed IP. This patent application is the base for a contract for developing and licensing the technology for biomedical applications by a multinational company.
    Brief description: This application covers a system and method aimed to monitoring one or more conditions of a subject's body. The system comprises a control unit which comprises an input port for receiving image data, a memory utility, and a processor utility. The image data is indicative of data measured by a pixel detector array and is in the form of a sequence of speckle patterns generated by a portion of the subject's body in response to illumination thereof by coherent light according to a certain sampling time pattern. The memory utility stores one or more predetermined models, the model comprising data indicative of a relation between one or more measurable parameters and one or more conditions of the subject's body. The processor utility is configured and operable for carrying out the following: processing the image data and determining a spatial correlation function between successive speckle patterns in the sequence, and determining a time varying spatial correlation function in the form of a time-varying function of at least one feature of the correlation function, the time-varying spatial correlation function being indicative of a change of the speckle pattern over time; selecting at least one parameter of the time- varying spatial correlation function, and applying to said at least one parameter one or more of the models to determine one or more corresponding body conditions; and generating output data indicative of said one or more corresponding body conditions.
  • European Patent application 4

    Inventors: Javier Garcia Monreal, Vicente Mico Serrano, Ian Wallhead, Jose Vicente García Ortíz, Jose Ignacio González Toledo, and Cristóbal González Toledo.
    Title: Multi-order diffractive optical element for concentration of broadband electromagnetic radiation.
    European Application Number: 12188757.4-2217.
    Filing date: 17-Oct-2012.
    Brief description: This patent application describes an optical element for collecting broadband electromagnetic radiation and that includes an input face and an output face. The first input face receives electromagnetic radiation of many wavelengths consistent with a broadband spectrum such as the sun. At the second output surface the light exits the optical element in the direction towards a focus where the electromagnetic energy is received by a receiver. One or both of the first input and second output surfaces incorporates a multi-order diffractive component which contributes in whole or in part to the deviation of light rays from their incident direction toward the region of the focus of the optical element.
