Patent number: 11870148Abstract: A planar conductive millimeter-wave lens includes: a planar conductive plate with a first surface and a second surface, wherein the first surface is parallel to the second surface; a plurality of openings from the first surface through the planar conductive plate to the second surface, where an axis of each opening is perpendicular to the first surface and the second surface. A size of each opening is a function of a position of said each opening on the planar conductive plate such that an insertion phase collectively imposed by the openings on an incident wave causes the incident wave to pass through the first surface and the planar conductive plate, exit from the second surface and to focus at a predetermined distance from the second surface.Type: GrantFiled: November 11, 2021Date of Patent: January 9, 2024Assignee: RAYTHEON COMPANYInventors: David D.

Patent number: 11060822Abstract: An apparatus includes at least one transmitter configured to transmit wireless signals that create different localized heating in different portions of a scene. The different localized heating in the different portions of the scene is based on different moisture or liquid content within objects in the scene. The apparatus also includes at least one controller configured to control the at least one transmitter in order to control the different localized heating in the different portions of the scene and to create a desired thermal radiation pattern in the scene. The desired thermal radiation pattern in the scene may include a camouflage pattern that increases clutter in an infrared image, at least one temporary infrared marker, or at least one false shape in an infrared image. The desired thermal radiation pattern could reduce a contrast between a cold infrared background in the scene and one or more targets in the scene.Type: GrantFiled: February 17, 2020Date of Patent: July 13, 2021Assignee: Raytheon CompanyInventor: Hooman Kazemi

Patent number: 9647325Abstract: A flexible, printable antenna for automotive radar. The antenna can be printed onto a thin, flexible substrate, and thus can be bent to conform to a vehicle body surface with compound curvature. The antenna can be mounted to the interior of a body surface such as a bumper fascia, where it cannot be seen but can transmit radar signals afield. The antenna can also be mounted to and blended into the exterior of an inconspicuous body surface, or can be made transparent and mounted to the interior or exterior of a glass surface. The antenna includes an artificial impedance surface which is tailored based on the three-dimensional shape of the surface to which the antenna is mounted and the desired radar wave pattern. The antenna can be used for automotive collision avoidance applications using 22-29 GHz or 76-81 GHz radar, and has a large aperture to support high angular resolution of radar data.Type: GrantFiled: August 29, 2014Date of Patent: May 9, 2017Assignee: GM Global Technology Operations LLCInventors: Kevin Geary, Joseph S.

Patent number: 9252247Abstract: The interface resistance between the source/drain and gate of an HFET may be significantly reduced by engineering the bandgap of the 2DEG outside a gate region such that the charge density is substantially increased. The resistance may be further reduced by using an n+GaN Cap layer over the channel layer and barrier layer such that a horizontal surface of the barrier layer beyond the gate region is covered by the n+GaN Cap layer. This technique is applicable to depletion and enhancement mode HFETs.Type: GrantFiled: January 10, 2014Date of Patent: February 2, 2016Assignee: HRL Laboratories, LLCInventors: Miroslav Micovic, Andrea Corrion, Keisuke Shinohara, Peter J Willadsen, Shawn D Burnham, Hooman Kazemi, Paul B Hashimoto

Patent number: 9171247Abstract: Described is a pattern matching system for matching a test image with a 3D template. The system is initiated by generating a library of templates (each individual template is a three-dimensional array, with each pixel in the array representing a value at a particular x, y, and z coordinate). Each column of pixels along one axis (e.g., z) is converted into a neural input. Each neural input is fed through a neural network to establish a delayed connection between each neural input and output neuron and to generate a template neural network. Separately, a test image is converted into neural inputs. The neural inputs of the test image are input the template neural network to generate output neurons. The output neurons are evaluated to identify a location of the template in the test image.Type: GrantFiled: January 23, 2013Date of Patent: October 27, 2015Assignee: HRL Laboratories, LLCInventors: Heiko Hoffmann, Hooman Kazemi
