  • Patent number: 9971078
    Abstract: Image-sensing devices include odd-symmetry gratings that cast interference patterns over a photodetector array. Grating features offer considerable insensitivity to the wavelength of incident light, and also to the manufactured distance between the grating and the photodetector array. Photographs and other image information can be extracted from interference patterns captured by the photodetector array. Images can be captured without a lens, and cameras can be made smaller than those that are reliant on lenses and ray-optical focusing.

  • Patent number: 9965200
    Abstract: In large complex multi-path storage environments, knowing there is a problem is extremely valuable. Example embodiments of the present invention include a management framework that provides an easy to use and read graphical perspective that allows analysis of faults in a multi-path storage environment. The architecture is not only responsive, scalable, and robust, but also provides “middleware” services to a broad spectrum of enterprise management applications whose domains may extend beyond storage path management.

  • Publication number: 20180091705
    Abstract: An imaging system with a diffractive optic captures an interference pattern responsive to light from an imaged scene to represent the scene in a spatial-frequency domain. The sampled frequency-domain image data has properties that are determined by the point-spread function of diffractive optic and characteristics of scene. An integrated processor can modified the sampled frequency-domain image data responsive to such properties before transforming the modified frequently-domain image data into the pixel domain.

  • Publication number: 20180031372
    Abstract: Binocular depth-perception systems use binary, phase-antisymmetric gratings to cast point-source responses onto an array of photosensitive pixels. The gratings and arrays can be manufactured to tight tolerances using well characterized and readily available integrated-circuit fabrication techniques, and can thus be made small, cost-effective, and efficient. The gratings produce point-source responses that are large relative to the pitch of the pixels, and that exhibit wide ranges of spatial frequencies and orientations. Such point-source responses make it easy to distinguish the point-source responses from fixed-pattern noise the results from spatial frequencies of structures that form the array.

  • Patent number: 9876043
    Abstract: An array of diffraction-pattern generators employ phase anti-symmetric gratings to projects near-field spatial modulations onto a closely spaced array of photoelements. Each generator in the array of generators produces point-spread functions with spatial frequencies and orientations of interest. The generators are arranged in an irregular mosaic with little or no short-range repetition. Diverse generators are shaped and placed with some irregularity to reduce or eliminate spatially periodic replication of ambiguities to facilitate imaging of nearby scenes.

  • Publication number: 20180020157
    Abstract: Image-sensing devices include odd-symmetry gratings that cast interference patterns over a photodetector array. Grating features offer considerable insensitivity to the wavelength of incident light, and also to the manufactured distance between the grating and the photodetector array. Photographs and other image information can be extracted from interference patterns captured by the photodetector array. Efficient extraction algorithms based on Fourier deconvolution introduce barrel distortion, which can be removed by resampling using correction functions. The sensing devices can be made to minimize distortion that results from efficient extraction algorithms based on Fourier deconvolution.

  • Publication number: 20170320668
    Abstract: A material handling hopper includes an integrally formed handling body that defines an inlet, an outlet, and an axis. The handling body has a seamless sidewall extending between the inlet and the outlet. The sidewall is circular in cross section in a plane perpendicular to the axis. The sidewall is curvilinear and defines a first height between an axial location of a first inner diameter and an axial location of a second inner diameter.

  • Patent number: 9808572
    Abstract: A number of racks which are configured to allow a number of devices to couple thereto are provided. In some embodiments, the racks are for use with a number of medical devices. Devices may be coupled to a rack by clamps. The racks may include a number of connectors which provide power and/or a network connection to devices coupled thereto. The racks may include a clamp which allows the racks to couple to a supporting structure such as a pole.

  • Publication number: 20170300011
    Abstract: An optical phase grating produces an interference pattern rich in intensity and spatial-frequency information from the external scene. The grating includes an odd number of repeated sets of adjacent horizontal portions, separated by steps, that fill an area that radiates outward from a central region. At a given distance from the central region and within the area of the phase grating, each of the first horizontal portions is of a first width that differs from a second width of the adjacent second horizontal portions. The interference patterns produced by the grating can be processed to extract images and other information of interest about an imaged scene.

  • Publication number: 20170292527
    Abstract: A centrifugal pump, and components thereof, operable at high speeds, is described under the present disclosure. A hard polymer sleeve can be applied to certain surfaces of a seal casing within the pump. If the sleeve is applied along surfaces near the center shaft, then the hard polymer will withstand the forces and pressures of the system. The hard polymer might not be used along the outer diameter, farther from the shaft, because velocities are higher the further out one goes. The current disclosure allows for the use of fluoropolymer in the lining sleeve. The benefits of fluoropolymer have been unavailable in high speed centrifugal pumps because the forces are too great on the periphery of the seal casing. However, the lower speeds along the interior, near the shaft, allow fluoropolymer to be used.

  • Patent number: 9772432
    Abstract: A sensing device with an odd-symmetry grating projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the spatial modulations are in focus for a range of wavelengths and spacings. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. Used in conjunction with a converging optical element, versions of these gratings provide depth information about objects in an imaged scene. This depth information can be computationally extracted to obtain a depth map of the scene.

  • Patent number: 9746593
    Abstract: Described are imaging devices that employ patchworks of diffractive structures as focusing optics. Each diffractive structure best focuses light over a relatively narrow cone of incident angles, and provides suboptimal focusing for incident angles outside that cone. Different diffractive structures best focus different angular ranges, with the patchwork thus providing an overall focusable response for the relatively broad range of angles required to image a scene. Images can be captured without a lens, and cameras can be made smaller than those that are reliant on lenses and ray-optical focusing.
