  • MONITORING SYSTEMS
    Publication number: 20200364999
    Abstract: A system can use a video analytic algorithm and/or other input parameters to identify an event (e.g., theft). Optionally, the system can take action in response. For example, the security system can use video analytics to determine that a person has reached into a shelf multiple times at a rate above a threshold, which can indicate that a thief is quickly removing items from the shelf. A monitoring system can monitor other areas for breaches, such as an entrance to a store or residence. Monitoring entrances and/or exits can be used to determine occupancy, or to determine rush events to prompt customer service action, such as opening additional point of sale stations.

  • Process and system for fabricating a colored powder coating composition from solid filaments
    Patent number: 10836077
    Abstract: A process and system for rapidly fabricating small batches of powder coating compositions having desired colors from one or more solid input filaments. An additive manufacturing filament fabricator feeds one or more single-color solid polymer input filaments into a heated mixer in accordance with an input formulation to be liquefied and mixed to produce a homogenous extrudate mixture. The extrudate mixture is solidified on an extrudate receiving platform and is then comminuted by an extrudate mill into a finished powder coating composition having a desired color.

  • System and method for assessing and validating wind turbine and wind farm performance
    Patent number: 10815972
    Abstract: A method for assessing or validating wind turbine or wind farm performance produced by one or more upgrades is provided. Measurements of operating data from wind turbines in a wind farm are obtained. Baseline models of performance are generated, and each of the baseline models is developed from a different portion of the operating data. A generating step filters the wind turbines so that they are in a balanced randomized state. An optimal baseline model of performance is selected from the baseline models and the optimal baseline model includes direction. The optimal baseline model of performance and an actual performance of the wind farm or wind turbine is compared. The comparing step determines a difference between an optimal baseline model of power output and an actual power output of the wind farm/turbine. The difference is reflective of a change in the power output produced by the upgrades.

  • Eye emulator devices
    Patent number: 10817052
    Abstract: Described herein is a human eye emulator device that emulates the human eye's responses to light. The human eye emulator device is based on an electro-optical liquid crystal eye model. The human eye emulator device includes a Pancharatnam berry phase (PBP) liquid crystal (LC) lens, a liquid crystal (LC) shutter glass, and a liquid crystal (LC) lens. The PBP LC lens emulates the cornea. The PBP LC lens receives light and refracts the received light. The LC shutter glass emulates the pupil. The LC shutter glass forms a dynamic aperture that transmits a portion of the light refracted by the PBP LC lens. The LC lens emulates the crystalline lens. The LC lens receives the portion of light transmitted by the LC shutter glass and refracts the received portion of light through the LC shutter glass onto an imaging surface.

  • Apochromatic pancharatnam berry phase (PBP) liquid crystal structures for head-mounted displays
    Patent number: 10809585
    Abstract: A Pancharatnam Berry Phase (PBP) liquid crystal structure for adjusting or focusing light of a plurality of color channels emitted by a display of a head-mounted display (HMD) comprises a plurality of PBP active elements. Each PBP active element of the structure is configured to act as a half waveplate for light of a corresponding color channel, such that light of the corresponding color channel is adjusted by a predetermined amount. In addition, each PBP active element acts as a one waveplate for light of the remaining color channels, such that light of the remaining color channels passes through the PBP active element substantially unaffected. As such, the PBP structure is able to adjust incident light of the plurality of color channels uniformly in an apochromatic fashion.

    Abstract: A near-eye display (NED) has an orientation detection device and a display block. The orientation detection device collects orientation data that describe an orientation of the NED. The display block has a display assembly, a focusing assembly, and a controller. The controller determines an orientation vector of the NED based in part on the orientation data and computes an angular difference between the orientation vector of the NED and a gravity vector. After comparing the angular difference to a threshold value, the controller generates multifocal instructions that adjusts the optical element to display an augmented scene at the selected image plane corresponding to the multifocal instructions.

    Patent number: 10750989
    Abstract: Systems and methods for noninvasively determining the function capacity of the kidney are provided. In the methods, first contrast agent is injected into the vasculature of a subject. The contrast agent is to be bound with functioning glomeruli of the kidney of the subject. Then, the kidney is imaged with a magnetic resonance imaging (MRI) system to acquire MRI images of the kidney. In the images, signal magnitudes or phases of voxels of regions bound with the contrast agent are different from signal magnitudes or phases of voxels of regions not bound with the contrast agent. Afterwards, the function capacity of the kidney is determined using the MRI images. Lastly, a report of the function capacity of the kidney is generated.

  • Apparatus and Methods for Aligning Photopolymers Using an Asymmetrically Focused Beam
    Publication number: 20200257171
    Abstract: A method for aligning a layer of photopolymers includes projecting light onto a rotating optical element and asymmetrically focusing the light transmitted through the rotating optical element onto a layer of photopolymers. The asymmetrically focused light is swept across different regions of the layer of photopolymers while a direction of polarization in the light is varied due to the rotation of the first optical element, producing a pattern of orientations for the layer of photopolymers. The method can be incorporated in a raster-scanning process to produce an alignment pattern in a layer of photopolymers with a large surface area, and is faster and provides improved precision and/or uniformity of the alignment pattern compared to currently available methods. An apparatus for aligning the layer of photopolymers is also disclosed.
