Patent number: 7898265Abstract: A microwave paint thickness sensor includes a single cylindrical cavity, a microwave source, and a signal detector. The cylindrical cavity is open at one end, the open end having a choke joint for interfacing with a painted surface. The cylindrical cavity is designed so that the electronic field is normal to the painted surface. In a preferred embodiment, this is accomplished by providing an optimally designed TM011 mode cavity. In this configuration, the resonant frequency of the cavity is linearly related to the inverse of the paint thickness. In accordance with one aspect of the present invention, the resonant cavity is optimally sized to resonate at a frequency where the sensor footprint can be minimized. Thus with the use of the choke joint, the small sensor interface area of the present invention may easily be applied to a curved surface.Type: GrantFiled: December 4, 2007Date of Patent: March 1, 2011Assignee: The Boeing CompanyInventors: Jimmy S. Takeuchi, Milton Perque, Patrick Anderson, Edward G. Sergoyan

Patent number: 7889135Abstract: An antenna array core comprising a plurality of microwave modules, a control layer, a mounting layer, and a signal distribution layer. The control layer is capable of distributing control signals to the plurality of microwave modules. The plurality of microwave modules are attached to an upper surface of the mounting layer and the mounting layer is made from a heat conductive material capable of cooling the plurality of microwave modules. The signal distribution layer is located below the mounting layer, wherein the signal distribution layer is capable of transmitting microwave signals to the plurality of microwave modules and wherein the arrangement of the plurality of microwave modules on the mounting layer, the control layer, and the wave distribution network form a layered architecture for the antenna core. The architecture is a balance between, size, thermal control, manufacturability, cost, and performance so as to be a unique solution.Type: GrantFiled: June 19, 2007Date of Patent: February 15, 2011Assignee: The Boeing CompanyInventors: Bruce Larry Blaser, Peter Timothy Heisen, Richard N. Bostwick, John B. O'Connell, Stephen Lee Fahley, Julio A. Navarro, Mark Richard Davis, Harold Peter Soares, Jr., Scott A. Raby, Jimmy S. Takeuchi

Patent number: 7495521Abstract: A multi-channel circulator or isolator well suited for use in phased array antennas or other RF devices where space and packaging constraints make the implementation of a conventional circular or isolator difficult or impossible. The multi-channel circulator/isolator can be configured as an isolator by the inclusion of one or more load resistors at one of its ports. In various configurations two or more ferrite substrates are provided that each provide a plurality of transmission ports. One or more permanent magnets are used to simultaneously provide the magnetic flux field through both of the substrates. The substrates can be configured such that they are spaced apart by a small distance, or positioned face to face in contact with one another. One or a plurality of magnets can be used depending upon RF requirements. Each substrate forms an independent electromagnetic wave propagation channel that limits the propagation of RF energy between its ports in one direction only.Type: GrantFiled: June 27, 2007Date of Patent: February 24, 2009Assignee: The Boeing CompanyInventors: Ming Chen, Jimmy S Takeuchi, Douglas A Pietila
