Publication number: 20240151895Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.Type: ApplicationFiled: June 2, 2023Publication date: May 9, 2024Inventors: Wilson Dau, Robert C.

Patent number: 10534080Abstract: A system is provided for synthetic aperture radar image formation within a distributed network. A radar antenna receives successive echoes of a plurality of pulses of radio waves transmitted in an environment of a target. A processing system defines, from the successive echoes, an array of data elements representing a density of a reflective surface of the target at locations within the environment. The processing system also partitions the array into a plurality of subarrays based on a predefined array partitioning scheme. A respective node of a plurality of nodes receives and applies at least one algorithmic transform to a subarray of the plurality of subarrays, and determines a respective portion of a volume of space occupied by the target based thereon. The respective portion is combinable with other respective portions to determine the volume of space and thereby form an image of the target.Type: GrantFiled: March 28, 2016Date of Patent: January 14, 2020Assignee: The Boeing CompanyInventor: Brian H.

Patent number: 8134489Abstract: A method for monitoring an area that involves transmitting a first electromagnetic wave signal from a mobile platform moving over a ground surface, toward the ground surface. A receiver is used that is located remote from the mobile platform to receive the first electromagnetic wave signal after the signal is reflected from the ground surface. The first electromagnetic wave signal is processed to form a first synthetic aperture radar (SAR) image. Subsequently the receiver is used to receive a second electromagnetic wave signal transmitted from the mobile platform at a time subsequent to transmission of the first electromagnetic wave signal. The second electromagnetic wave signal is then processed to obtain a second SAR image. The first and second SAR images are then coherently analyzed to determine areas of non-correlation between the images.Type: GrantFiled: July 14, 2008Date of Patent: March 13, 2012Assignee: The Boeing CompanyInventor: Brian H.

Patent number: 6850464Abstract: A method and apparatus for dimensioning and, optionally, weighing a cuboidal object. Four distance sensors are employed, one downwardly facing the top of the object, one facing one side thereof and two respectively facing mutually parallel sides of the object perpendicular to the one side. Distances are measured between the sensors and the top and sides of the object and subtracted from known distances to determine the length, width, height and spatial volume of the object. The object may be weighed as it is being dimensioned. Spatial volume and a “dim weight” for the object may be calculated.Type: GrantFiled: February 5, 2003Date of Patent: February 1, 2005Assignee: Quantronix, Inc.Inventors: Eve A. Carlsruh, Craig R.

Patent number: 6111535Abstract: A method of minimizing leakage energy in a synthetic aperture radar (SAR) system is based a Lagrangian function constructed from image-domain magnitude, and a "penalty function" based upon the choice of aperture. Broadly, the choice of penalty function is related to an estimate of undesirable energy lying outside of the main lobe of the impulse response introduced by the given aperture. Since there are no non-analytic constraints, the output image is purely an analytic function of the input, resulting in a more straightforward analysis and implementation while lessening the likelihood of pseudo-random phenomena. A tunable relative coefficient betveen the sidelobe energy estimate and the output magnitude allows control over a physically well-understood tradeoff between clutter contrast and point resolution. The generality of the technique may be extended to a multi-parameter minimization with possible applications in super-resolution, gap-filling, interferometry, and ultrasonic imaging, and ATR.Type: GrantFiled: August 24, 1998Date of Patent: August 29, 2000Assignee: Veridian ERIM International, Inc.Inventor: Brian H.

Patent number: 5517063Abstract: A power bridge assembly for providing electric current to stator windings of an electric motor used in an electric propulsion system for an electric vehicle. The power bridge is assembled on a laminated bus bar. An upper plate of the bus bar connects to one side of a high voltage battery, a lower plate of the bus bar connects to the other side of the high voltage battery, and an insulation layer is sandwiched between the upper and lower plates. Electrical switches and capacitors sandwich the laminated bus bar. With this structure, two fasteners, one for positive voltage and one for negative voltage, can connect the bus bar, capacitors, and switches both electrically and mechanically. The sandwich structure eliminates parasitic inductance from the electrical connections.Type: GrantFiled: June 10, 1994Date of Patent: May 14, 1996Assignee: Westinghouse Electric Corp.Inventors: David L.
