Patent number: 12004308Abstract: Processes for laminating a graphene-coated printed circuit board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may include an inner core, an adhesive layer, and at least one graphene-metal structure. Pressure and heat—which may be applied under vacuum or controlled gas atmosphere—may be applied to the lamination stack, after all materials have been placed. The graphene of the graphene-metal structure is designed to promote high frequency performance and heat management within the PCB.Type: GrantFiled: July 1, 2021Date of Patent: June 4, 2024Assignees: Mellanox Technologies, Ltd., BAR-ILAN University, PCB Technologies LtdInventors: Boaz Atias, Elad Mentovich, Yaniv Rotem, Doron Naveh, Adi Levi, Yosi Ben-Naim, Yaad Eliya, Shlomo Danino, Eran Lipp

Patent number: 11963309Abstract: Processes for laminating a conductive-lubricant coated Printed Circuit Board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may further include a core, an adhesive layer, and at least one graphene-metal structure or at least one hexagonal Boron Nitride metal (h-BN-metal) structure. The materials of the PCB may change in accordance with the invention described herein, including the materials of the core, the materials of the conductive-lubricant coatings, or the metal layers of the conductive-lubricant-metal structures. Doping processes for each change in materials used are also described herein. The conductive-lubricant of the conductive-lubricant-metal structure will promote high frequency performance and heat management within the PCB. Furthermore, a removal process of those materials post-lamination is described herein to promote protection of materials and subsequent removal of protective layers without breakage or tearing.Type: GrantFiled: July 1, 2021Date of Patent: April 16, 2024Assignees: MELLANOX TECHNOLOGIES, LTD., BAR-ILAN UNIVERSITY, PCB TECHNOLOGIES LTD.Inventors: Boaz Atias, Elad Mentovich, Yaniv Rotem, Doron Naveh, Adi Levi, Yosi Ben-Naim, Yaad Eliya, Shlomo Danino, Eran Lipp, Alon Rubinstein, Ran Hasson Ruso

Patent number: 11791562Abstract: A ring focus antenna system has an ultra-wide bandwidth for receiving and transmitting electromagnetic (EM) signals. The system includes a main reflector having an axis of rotation and a splash plate feed assembly consisting of a waveguide and a sub-reflector which is substantially aligned with the axis of rotation. The sub-reflector has surfaces that include segments of a displaced ellipse, having a first focal point which coincides with an ISO phase center located inside the waveguide and a second focal point located on a ring focus of the main reflector. A dielectric support for the sub-reflector has a shaped boundary which eliminates refraction at the dielectric-air interface. In one embodiment, the ultra-wide bandwidth includes EM frequencies belonging to Ku-band and Ka-band communication frequencies. The waveguide may be configured as a quad-ridged polarizing waveguide.Type: GrantFiled: April 4, 2022Date of Patent: October 17, 2023Assignee: ORBIT COMMUNICATION SYSTEMS LTD.Inventors: Alon Leib, Hanan Keren, Shlomo Levi, Itzik Krepner

Patent number: 8648748Abstract: An effective marine stabilized antenna system, in terms of antenna to radome size and antenna/RF performance complies with all relevant worldwide SatCom regulations. The combination of a dual offset Gregorian antenna (DOGA) with a stabilized polarization over elevation over tilt over azimuth pedestal, and a control/stabilization algorithm, ensures antenna orientation restrictions guarantee compliance with side-lobe intensity regulations. Operating a dual offset Gregorian antenna substantially within a pre-determined antenna cut range of a 45 degree angle relative to a configuration of the antenna and a relative position of a target provides antenna performance that complies with applicable SatCom regulations, despite having to flip the antenna 90 degrees to continue tracking the satellite.Type: GrantFiled: February 13, 2011Date of Patent: February 11, 2014Assignee: Orbit Communication Ltd.Inventors: Azriel Yakubovich, Guy Naym, Idan Fogel, Ervin Rozman, Shlomo Levi, Michael Greenspan, Moshe Gvili, Or Dadush, Benny Ben Rey

Patent number: 6630309Abstract: Binding between two members of a recognition pair, e.g. antigen-antibody is determined by utilizing a probe which includes a piezoelectric crystal with electrodes on two opposite faces of the crystal. The crystal carries one or more metal plates which may be the same or different than the electrodes, the metal plates having immobilized thereon a first member of a recognition pair. Binding of a second member of the recognition pair to the first member, or dissociation between the two members and release of the second member from the probe, causes a change of immobilized mass which results in a change to the probe's resonance frequency.Type: GrantFiled: June 4, 1998Date of Patent: October 7, 2003Assignees: Biosensor Applications Sweden AB, Yissum Research Development Company of the Hebrew University of JerusalemInventors: Itamar Willner, Shlomo Levi, Yael Cohen, Eugenii Katz, Arie Dagan
