Patent number: 7436498Abstract: An apparatus for determining the shape of a gemstone, including irregularities on its surface, is provided, The apparatus comprises a platform adapted to support the gemstone, a scanning system adapted to provide geometrical information concerning the three-dimensional convex envelope of the gemstone, an illumination system adapted to project on the gemstone a plurality of laser beams, an imaging system adapted to capture reflections of at least a part of said laser beams from the surface of the gemstone, and a processor. The processor is adapted to calculate, based on said geometrical information, a predicted reflection of each laser beam, to compare the captured reflections with said predicted reflections and to relate each captured reflection to its corresponding predicted reflection, to determine said shape of the gemstone based on the comparison and said geometrical information.Type: GrantFiled: June 8, 2006Date of Patent: October 14, 2008Assignee: Sarin Technologies Ltd.Inventors: Avi Kerner, Yedidya Ariel, Nur Arad

Publication number: 20040032398Abstract: A method, device, and system for facilitating the use of and data entry into a computer having a data entry device such as a keyboard and a display device such as a monitor. A camera is disposed above the keyboard and captures a moving image of the keyboard. The image of the keyboard is shown on th display device, preferably in a small portion of the display device. In this way, a person can look at the display device and see both the subject matter he is typing or entering and the keyboard at the same time. An image of the user's hands is made transparent and overlaid onto the image of the keyboard. The image of the keyboard can be manipulated, e.g., made smaller or larger, corrected for parallax and movement, the characters on the keys can be changed, and the like.Type: ApplicationFiled: August 16, 2003Publication date: February 19, 2004Inventors: Yedidya Ariel, Gilad Taub

Publication number: 20030068150Abstract: A method of preventing contamination of the air channels in the capillaries or pores of an air-clad or photonic-crystal fiber during polishing of the end-faces. A glass or silica fiber rod of diameter comparable to the fiber is fused to the end-face of the fiber, cut, and polished to form a thin protective plate having no appreciable affect on the optical properties of the fiber. Alternatively the air capillaries may be sealed by a UV-curable fluid or by melting the surrounding material. The end-face of the fiber thus presents a polished or cleaved surface for optical coupling to other fibers without causing damage or contamination to the air channels of the fiber. Furthermore, treating both end-faces of an air-clad or photonic-crystal fiber in manner provides a hermetic seal for the air-channels and protects the fiber against degradation caused by contamination such as humidity and dust which would otherwise enter the air channels over the course of time.Type: ApplicationFiled: March 13, 2002Publication date: April 10, 2003Applicant: Rayteq Photonic Solutions Ltd.Inventors: Yedidya Ariel, Eilon Sherman, Anatoly Patlakh, Rafael Bronstein
