| 20130044221 | DUAL FIELD OF VIEW MULTI-BAND OPTICS - A dual field of view, all-refractive infrared optical system that images the mid-wave infrared light in one field of view and the short wave infrared light in the second field of view onto the same detector. The two fields of view vary in focal length by a factor of six. The narrow field of view images the SWIR radiation at a slow f/number of 10.0 while the wide field of view images the MWIR radiation at f/1.9. The field of view is changed via a single lens that changes its axial position within the lens, resulting in an axial zoom. The change in focal length and f/number at the same time enables an increased focal length without having to increase the aperture size by the ratio of the focal length change, but rather by the ratio of the focal length change divided by the ratio of the f/number change. | 02-21-2013 |
| 20130042449 | ROCKET MOTOR PROPELLANT SEGMENTING MACHINE - The invention relates to a machine for cutting a radial slice or segment of a metal casing-covered cylinder of rocket motor propellant.

| 20130016270 | Radial Readout Approach to EO ImagersAANM Antesberger; A. WayneAACI WoodbridgeAAST VAAACO USAAGP Antesberger; A. Wayne Woodbridge VA US - A radial based approach to electro-optic imagers, rather than the conventional rectilinear approach, would have basic overall system design advantages. Those system design advantages would apply to the components and the entire system implementation and include approaches to objective optical design, focal plane array FPA with fill factor, FPA layout and associated read-out integrated circuit ROIC, support electronics architecture and associated memory requirements, image processing IP algorithms, display layout and format, and eyepiece optics. A radial based approach to EO imagers would yield a device/system with attributes requiring less complicated optical components, with potentially fewer elements, for both the objective and eyepiece lenses. In addition, alternative objective optics could be more easily employed, such as holographic or wave front coded, due to reduced complexity of implementing correction algorithms as a result of referencing the system around its optical axis. The radial readout EO system would have pixel ‘one’ at the center and be ‘read out and displayed’ like the rings of a tree rather than words on a page. | 01-17-2013 |
| 20120307061 | Apparatus for identifying threats using multiple sensors in a graphical user interface - A system of imaging and non-imaging sensors are used in combination with a graphical user interface (GUI) system on a vehicle to detect items of interest.

| 20120162750 | DUAL BAND INFRARED CONTINUOUS ZOOM LENS - A continuous zoom lens arrangement can image MWIR and LWIR spectral bands to a common image plane. Such an exemplary optical system comprises eight infrared imaging lenses that all transmit over the wavelengths 3.5-11.0 microns and form a collocated image plane for the MWIR and LWIR spectral bands. The lens has six stationary lenses, and two lenses that move in arm axial fashion. A cold stop inside the dewar can act as the aperture stop of the system and control the stray light from reaching the FPA. The pupil is reimaged from the cold stop to near the first lens of the system to minimize the size of the lens. The optic is designed to operate at an f/number of 3.0 and provides a focal length range from 38 mm to 130 mm for a 640×480 element focal plane array with 20 micron square pixels. This has an equivalent image plane diameter of 16 mm. Such an optical system can work with a cold shield height of about 29.46 mm. The range in focal length result in an overall zoom change of 3.42×. | 06-28-2012 |
| 20120161314 | TEMPLATE WAFER AND PROCESS FOR SMALL PITCH FLIP-CHIP INTERCONNECT HYBRIDIZATION - A process is disclosed for high density indium bumping of microchips by using an innovative template wafer upon which the bumps are initially fabricated. Once fabricated, these bumps are transferred to the microchip, after which can be hybridized to another microchip. Such a template wafer is reusable, and thus provides an economical way to fabricate indium bumps. Reusability also eliminates nonuniformities in bump shape and size in serial processing of separate microchips, which is not the case for other indium bump fabrication processes. Such a fabrication process provides a way to form relatively tall indium bumps and accomplishes this without the standard thick photoresist liftoff process. The described process can be suitable for bump pitches under 10 microns, and is only limited by the resolution of the photolithography equipment used. | 06-28-2012 |

For example, an exemplary system can have a sensor that captures infrared line images for personnel detection by scanning through a sensing plane of a linear array's field of view. In such a system, a processor controls the array sensor and stores the resulting images. Velocity characteristics of moving objects are incorporated into the images over time resulting in horizontal velocity profile images. Long wave infrared (LWIR) radiation can be sensed, which works in day and night conditions without illumination. LWIR sensors, such as microbolometers, as well as pyroelectrics, can be used. | 02-16-2012 |
| 20120027034 | Beam Quality of the Monoblock Laser Through Use of a 1.5 Micron External Cavity Partial Reflector - A monoblock laser cavity incorporates optical components for a short-pulse laser.

| 20120001789 | DIGITAL REGISTRATION OF 3D LASER RADAR DATA BASED ON MANUALLY SELECTED FIDUCIALS - A system and method for registering 3D data sets is disclosed based on manual fiducial selection. The technique is useful in imaging obscured targets with 3-D imaging laser radars. For such an exemplary method, which defines a three-dimensional linear shift vector for each data voxel, four fiducials are required to completely define the mapping for a 3D space. An exemplary registration algorithm as disclosed provides an approach to automatically make fine adjustments to the 3D data registration. The tedious technique of shifting data sets relative to each other, in many degrees of freedom, is eliminated. Instead, a fine adjust is applied to the digital mapping function, through fiducial perturbation. | 01-05-2012 |
| 20110317294 | MULTI-FIELD OF VIEW ANNULAR FOLDED OPTICS - An all-reflective afocal lens is comprised of eight-reflective mirrors which can fold the light path into a very compact and thin configuration while maintaining diffraction limited performance. Such an afocal arrangement is usable with a traditional optical imager of an appropriate aperture dimension and FOV range, or with an annular aperture optical system with the appropriately scaled aperture and acceptable FOV angles. When combined the resulting FOV is scaled by the magnification produced by the afocal. The afocal arrangement can be used in either a magnification mode or a demagnification mode. Such an afocal arrangement can be used as either a focal length extender or as a FOV switch enabling a very short length two FOV multi-spectral system with a length that can be an order of magnitude shorter than a known optical system. | 12-29-2011 |
| 20110315878 | SIMULTANEOUS DUAL BAND DUAL FOV IMAGING SYSTEM - A two fields-of-view system has both fields of view imaged simultaneously to the same image plane. For example, an optical system comprising of two or more FOV where a common dual band focal plane array is used in order to image both spectral bands independently. Each spectral band is passed through a common imager, but split off by a beam splitter so that each spectral band sees a different field of view centered at the same point. The two fields of view are separated spectrally but enabled to be imaged simultaneously due to the spectral separation of the focal plane array and the use of a beam splitter. Such a system allows viewing two fields of view simultaneously. | 12-29-2011 |
| 20110292506 | EYECUP FOR USE WITH NIGHT VISION GOGGLES AND OTHER OPTICAL DEVICES HAVING AN EYEPIECE - A vapor-permeable, vented eyecup for night vision goggles and other optical devices having an eyepiece. An eyecup is used to create a light tight seal between the eyepiece and the operator's face. In addition to containing the light from the optical device, the eyecup blocks out external light. When viewing through an optical device using a non-vented eyecup, moisture becomes trapped in the eyecup volume bounded by the operator's eye socket, eyecup, and eyepiece. Fog forms on the eyepiece as a result. This invention reduces the occurrence of fogging by allowing moisture to vent out of the volume through a vapor permeable material. This material allows vapor to pass but blocks larger water droplets, dust, dirt, and light. | 12-01-2011 |
| 20110286476 | Suppression of Parasitic Lasing - A laser gain medium crystal comprising a square rod of laser gain medium material having top and bottom surfaces that are finely ground to introduce scattering surfaces to cancel parasitic lasing.

| 20110240859 | ALTERNATIVE PIXEL SHAPE FOR UNCOOLED MICRO-BOLOMETER - An infrared imaging system including a substrate, a plurality of hexagonal shaped micro-bolometer pixels combined to define a focal plane array. Each pixel is electrically connected to the substrate with a pair of opposing isolation legs. One end of the isolation leg is attached to the pixel's periphery while the other is fixed to that substrate so that the focal plane array and a plane containing the substrate have a parallel, spaced-apart relationship. In this manner, the isolation legs provides an electrical communication path from each pixel to the substrate as each pixel undergoes an internal change in resistance due to absorption of infrared energy. At the same time, the legs separate the pixels from the substrate so that there is no heat transfer between the pixel and the substrate due to direct contact. The hexagonal shape arrangement also allows for a staggered arrangement of adjacent rows in the array, thereby increasing the fill factor for the focal plane array of the device. The addition of stepped areas to the hexagonal pixel provides for improved energy absorption through increase in area and multiple coupling of resonant cavities between the pixel and the substrate. | 10-06-2011 |
| 20110174078 | FIBER-OPTIC, DIGITAL SYSTEM FOR LASER DOPPLER VIBROMETERS (LDVs) - An apparatus and method for non-determination of the surface velocity of a target using optical interference and Doppler shifting of the light reflected from the target are disclosed.

The insert guard covers the receiving cavity and assists in orienting the fork lift receiving side to a location within the cavity where the attachment rod can be inserted through the reception path. A guide path formed in the top layer on the receiving side of the fork lift hitch receiver further aids in guiding the attachment rod to the reception path. A ball and a ball support member are attached to the trailer attachment side. | 03-24-2011 |
