Patent number: 8423122Abstract: This invention relates to methods and apparatus for localizing an in vivo imaging device by means of a single magnetic source coil assembly and a single magnetic detector coil assembly. This invention also relates to methods and apparatus to enable the use of a single magnetic source coil assembly to also transmit and receive information, images, and controls signals, as well as for the coil assembly to be used in DC-DC voltage conversion. A user interface with a display provides the user with the option of viewing selected images captured by the in vivo imaging device.Type: GrantFiled: July 6, 2009Date of Patent: April 16, 2013Assignee: Given Imaging Ltd.Inventors: Ben Zion Steinberg, Ido Bettesh

Patent number: 7941020Abstract: A rotating optical resonator, a waveguide and a method of use of waveguide are disclosed. The rotating optical resonator may include at least two modes of different resonant frequencies shiftable towards each other by reducing a magnitude of rotation rate, said modes being joinable into a substantially degenerate mode by setting substantially zero rotation rate, said resonator being of an optical size smaller than five wavelengths of the substantially degenerate mode. The waveguide may include a plurality of coupled evenly degenerate split mode resonators, the split of the modes forming a stop band in a resonant band of the waveguide, the stop band of the waveguide thereby being changeable by changing an angular velocity of the waveguide while the vector of the angular velocity is non-parallel with respect to the waveguide.Type: GrantFiled: July 23, 2008Date of Patent: May 10, 2011Assignee: Ramot at Tel-Aviv University Ltd.Inventors: Ben-Zion Steinberg, Amir Boag, Jacob Scheuer

Patent number: 7738110Abstract: A displacement sensor comprising at least one pair of co-planar photonic crystal waveguide (PCWG) sections aligned along or parallel to a common axis and separated by a gap, one PCWG section of a pair operative to perform a displacement relative to the other section of the pair. In some embodiments, the sensor is linear, comprising two PCWG sections separated by a gap that forms a cross PCWG, the displacement sensing performed preferrably differentially between two edges of the cross PCWG. In other embodiments, the sensor includes Mach Zehnder Interferometer (MZI) configurations with gaps between fixed and moving PCWG sections. Displacement induced changes in the gap widths are reflected in changes in an output parameter of the MZI.Type: GrantFiled: November 12, 2008Date of Patent: June 15, 2010Assignee: Ramot at Tel Aviv University Ltd.Inventors: Menachem Nathan, Ben Zion Steinberg, Oren Levy, Amir Boag

Patent number: 7613367Abstract: An optical device is presented for use in modulation of light and/or in sensing an external field, by at least partially, directly or indirectly exposing the device to the controllable or unknown external field. The device comprises a waveguide structure configured to define at least a first light channel having a light input and a light output, and having a first deformable resonating structure. The device thereby allows exposure of said at least first channel to the external field of the kind affecting a deformation of the first resonant structure thus causing a change in the first resonant wavelength, resulting in a corresponding change in at least one parameter of light output from said first channel, said change in the output light parameter being indicative of the external field.Type: GrantFiled: March 2, 2006Date of Patent: November 3, 2009Assignee: Ramot At Tel-Aviv University Ltd.Inventors: Oren Levy, Ben-Zion Steinberg, Amir Boag, Slava Krylov, Ilan Goldfarb

Patent number: 7385177Abstract: A method and device are presented for use in determining a rate of rotation of an object. The device comprises a light guide comprising an arrangement of a plurality of coupled optical resonators arranged along a curvilinear optical path. This allows for determining a change in at least one of the light phase and frequency affected by the light propagation through the curvilinear path during the device rotation, said change being indicative of the rotation rate of the light guide.Type: GrantFiled: January 5, 2006Date of Patent: June 10, 2008Assignee: Ramot at Tel-Aviv University Ltd.Inventors: Ben-Zion Steinberg, Amir Boag

Patent number: 7026640Abstract: A dynamically controllable photonic crystal comprises at least one micro-cavity, and electrical means to induce carrier refraction in the vicinity of the micro-cavity. In the exemplary case when the photonic crystal is implemented in a semiconductor substrate, localized carrier refraction is achieved using field induced carrier injection or depletion into a carrier concentration column surrounding the micro-cavity. Preferably, if the substrate is silicon, the injection and depletion is achieved using various two or three terminal, unipolar or bipolar structures.Type: GrantFiled: August 4, 2003Date of Patent: April 11, 2006Assignee: Ramot at Tel Aviv University Ltd.Inventors: Menachem Nathan, Ben Zion Steinberg, Amir Boag

Publication number: 20060055605Abstract: An antenna assembly (30) for a communication device (20) includes a feed structure (25), which has front and rear sides (26, 27), and which is coupled to be driven by the device so as to radiate an electromagnetic field in a given frequency band. An electrically reactive surface (28) is positioned adjacent to the rear side of the feed structure so as to define a cavity (35) between the feed structure and the reactive surface, thereby substantially nulling the electromagnetic field on the rear side of the feed structure.Type: ApplicationFiled: December 12, 2001Publication date: March 16, 2006Inventors: Asher Peled, Ehud Heyman, Ben-Zion Steinberg, Raphael Kastner, Amir Boag
