Patent number: 10345144Abstract: A Compact and Athermal VNIR/SWIR Spectrometer utilizes a slit, a Mangin lens, a pupil lens adjacent to the diffraction grating, corrector lenses, a beam splitter, field lenses and SWIR and VNIR FPAs. In examples, two corrector lenses are used. Some examples do not utilize field lenses and beam splitter, some examples utilize only the SWIR radiation spectrum. By balancing the powers of the optical elements and Abbe numbers of glasses as well as usage of aspheric surfaces combinations, a monochromatic and polychromatic aberrational correction is achieved; by balancing optical elements refractive indices change with temperature an athermalization is achieved. The overall length of the spectrometer does not exceed 4 inches, and in some examples it is 2.5 inches. A wide field of view and a low F number are obtained with an operating wavelength range from approximately 400 to 2350 nm. The spectrometer is particularly suited to airborne applications.Type: GrantFiled: July 11, 2017Date of Patent: July 9, 2019Assignee: BAE Systems Information and Electronics Systems Integration Inc.Inventors: Mark L Oskotsky, Michael J Russo, Jr.

Patent number: 10191275Abstract: An off-axis optical system having a rectangular aperture stop to control rays of incident electromagnetic radiation passing through the optical system along an optical path is provided. The optical system includes one or more optical surfaces along the optical path, each surface being configured to change a direction of each ray on the surface based on a location of the ray relative to the surface. At least one of the surfaces is conjugate to and has the same shape as the rectangular aperture stop. In one embodiment, each optical surface is shaped to avoid vignetting the rays. In one embodiment, the optical system is a three-mirror anastigmat (TMA) and includes a concave primary mirror to collect and focus the electromagnetic radiation; a curved secondary mirror to reflect the electromagnetic radiation focused by the primary mirror; and a concave tertiary mirror to focus the electromagnetic radiation reflected by the secondary mirror.Type: GrantFiled: July 6, 2017Date of Patent: January 29, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Ian B.

Patent number: 9710505Abstract: Described herein are system and methods for mitigating index contention issues in databases. The database server may generate additional storage locations to prevent overloading one or more current storage locations. A variety of database conditions may be used to trigger an increase or decrease in storage locations. In one embodiment, more storage locations may be generated when the amount of data records waiting to be written at a storage location exceeds or equals a threshold amount. Likewise, the database server may reduce the amount of current storage locations when the amount of data records is less than a threshold amount. The record identifiers may incorporate a location reference for their designated storage location. The reference may be a string that includes numbers, letters, or a combination thereof.Type: GrantFiled: July 21, 2015Date of Patent: July 18, 2017Assignee: Amazon Technologies, Inc.Inventors: Grant Alexander Macdonald McAlister, Chelsea C.
