  • Patent number: 10344773
    Abstract: A fan assembly includes a motor-driven impeller for creating an air flow, a casing including an interior passage for receiving the air flow, and a plurality of air outlets for emitting the air flow from the casing. The casing defines and extends about an opening through which air from outside the casing is drawn by the air flow emitted from the air outlets. The fan assembly also includes at least one heater for heating at least a first portion of the air flow, and means for diverting at least a second portion of the air flow away from said at least one heater. The plurality of outlets includes at least one first air outlet for emitting the relatively hot first portion of the air flow and at least one second air outlet for emitting the relatively cold second portion of the air flow.

  • Patent number: 10225995
    Abstract: This disclosure relates to agricultural canopies used primarily to control the amount of light, moisture and heat reaching growing plants within the canopy footprint. More specifically, it relates to mechanisms for pulling a flexible canopy over a support structure and then for removing the canopy to uncover the structure and the plants below. The mechanisms include an arm mounted rotationally on a base. When the arm is rotated in one direction the canopy is pulled over the support structure and when the arm is rotated in the other direction the canopy is pulled off the support structure.

  • Patent number: 10000714
    Abstract: Aqueous and substantially crystalline iron oxide nanoparticle dispersions and processes for making them are disclosed. The nanoparticle size and size distribution width are advantageous for use in a fuel additive for catalytic reduction of soot combustion in diesel particulate filters. Nanoparticles of the aqueous colloid are transferred to a substantially non-polar liquid comprising a carboxylic acid and one or more low-polarity solvents. The transfer is achieved by mixing the aqueous and substantially non-polar materials, forming an emulsion, followed by a phase separation into a substantially metal-free remnant polar phase and a substantially non-polar organic colloid phase. A method for rapid and substantially complete transfer of non-agglomerated nanoparticles to the low polarity phase in the presence of an organic amine, and a rapid phase separation of the substantially non-polar colloid from a remnant aqueous phase, are provided.

  • Patent number: 9839352
    Abstract: An apparatus for enabling corneal topography includes an attachment to align a placido disc illumination system with a camera of a mobile communication device. The placido disc illumination system generates concentric rings and reflects the concentric rings off a cornea. A portion of the reflected concentric rings are utilized to confirm vertex distance. The apparatus further comprises a memory, a processor, and computer-readable instructions in a mobile communication device. The camera captures an image of reflected concentric rings and communicates the captured image of the reflected concentric rings to an external computing device. A method for performing corneal topography utilizes a mobile computing and/or communication device, projects a plurality of peripheral concentric rings onto a subject's cornea and projects center rings onto the subject's cornea. The method further includes capturing, via a smartphone camera, an image of the projected peripheral concentric rings and the center rings.

  • Patent number: 9626383
    Abstract: Approaches for managing a library of digital images and information about any editing operations performed on those digital images are provided. A managed library of digital images and a referenced library of digital images may be maintained. Digital images may be moved from the managed library of digital images to the referenced library of digital images, and vice-versa. A preview digital image data may also be generated from master digital image data. Rather than performing image operations directly on the master digital image data, change data that identifies one or more operations to perform to a digital picture represented by either the preview digital image data or the master digital image data may be stored, thereby allowing operations to be performed on the preview digital image data when the master digital image data is not accessible. Digital image may be automatically renamed based on rules for doing so.
