  • Patent number: 11816706
    Abstract: There are provided systems and methods for intelligent interface displays based on past data correlations. A service provider and/or entity may implement a machine learning engine to dynamically adjust data displayed in interface elements of an interface provided by the service provider or entity. The data may correspond to an amount for a voluntary payment to the entity by a user and may be based on correlating and processing past user transactions and received entity payments. Weights may be applied to the data to determine median, average, and/or quartile amounts based on goals set by the user, events occurring at the time of the voluntary payment, and/or time of year. Once the machine learning engine determines one or more amounts specific to the user's payment to the entity, the engine may adjust or output the interface having the user specific data for processing.

  • Patent number: 10045703
    Abstract: An embodiment in accordance with the present invention provides a system and method for imaging living tissue and processing laser speckle data anisotropically to calculate laser speckle contrast preferentially along the direction of blood flow. In the present invention, raw laser speckle images are obtained and processed resulting in the anisotropic laser speckle images. The system and method involve the determination of the direction of blood flow for every pixel within the region of interest (primary pixel) and subsequent extraction of a set of secondary pixels in the spatio-temporal neighborhood of the primary pixel that is anisotropic in the direction of blood flow. Speckle contrast is then calculated for every primary pixel as the ratio of standard deviation and mean of all secondary pixels in this anisotropic neighborhood and collectively plotted using a suitable color mapping scheme to obtain an anisotropic laser speckle contrast image of the region of interest.

  • Patent number: 9977045
    Abstract: An apparatus providing for simultaneous measurement of the wind upstream and downstream of a wind turbine uses either a single LIDAR beam split into two beams, each focused upstream or downstream of the windmill, or a multiple beam LIDAR with a first beam source aimed toward the upstream direction of the wind and a second beam source aimed at the downstream direction after the wind has passed through the wind turbine. The apparatus may also use LIDAR to measure wind direction and speed by making measurements along slightly different lines of sight, or by pointing the LIDAR in different directions. Two lines of sight allow measuring wind direction in the plane defined by the two lines of sight. Three non-coplanar lines of sight provide the information necessary to determine a full 3-dimensional wind velocity vector. Further, LIDAR may also be used to measure wind speed by estimating the wind velocity using inputs from both aerosol and molecular components.

    Abstract: Systems are provided for detecting the flow of blood or other fluids in biological tissue by illuminating the biological tissue with a coherent light source and detecting time-varying patterns of constructive and destructive interference in light received from portions of the biological tissue by an imager. The movement of blood cells and other light-scattering elements in the biological tissue causes transient, short-duration changes in light emitted from portions of the biological tissue proximate to the moving blood cells or other scatterers. High-frequency sampling or other high-bandwidth processing of light intensities detected by an imager could be used to determine the flow of blood or other fluids at a plurality of points in the biological tissue, to detect and/or localize a tumor in the biological tissue, to determine the location, pattern, width, or other properties of vasculature in the biological tissue, or to provide information for some other application(s).

An array of single-mode optical fibers provides an optic signal to the multiple lens array. Numerous fibers in a fiber array project numerous rays to establish many measurement points at numerous different locations. One or more lens groups may be replaced with imaging lenses so a stereo image of the moving surface can be recorded.

    Abstract: In order to determine crosswind effects between a weapon and its intended target (204) a crosswind gradient measuring apparatus (600) directs a first pulsed coherent light beam (646) and a second pulsed coherent light beam (648) to the target (204). Light of both beams scattered back by aerosols in the air is measured by using a detector (652) thus generating a beat frequency in the detector signal. The beat frequency indicates a Doppler-shift due to crosswind as a function of range between weapon and target wherein the range is determined by the time of flight. The information determined by such a Doppler differential interferometer, DDI, is utilised by a signal processor (608) to calculate the bullet's crosswind offset which enables manual of automatic adjustment of an aiming mechanism.

With this, the speed, number and size of particles flowed through a micro-channel can be determined at a time, and associated data can be obtained.

  • Patent number: 8213023
    Abstract: A beam of light or other electromagnetic field is emitted and received in a vacuum, all within an apparatus in motion. The nature of light permits the beam of light to retain the characteristics of its motion in vacuum, regardless of motion of the apparatus in which the emitted light propagates. The light beam retains its position in space relative to the direction of motion of the apparatus. Since both entities, light beam and apparatus, are disposed in the same frame of reference, characteristics of their motion can be compared. The result of this comparison represents the vector of velocity V of the apparatus which is utilized in navigation of the apparatus.

  • Publication number: 20120154787
    Abstract: The present invention is a device to measure the characteristics of droplets within a stream of liquid droplets used in spraying. It comprises: a light source (45) supplying light across the stream of droplets; detection (means 2) to detect change in the light level caused by a passing droplet, the detection means generating a signal according to the change in light; and processing means (59) to analyse the characteristics of the droplets in the stream based on the signal produced by the detection means. The light passes through a slit (3A) in a panel (53) disposed between the droplet stream and the detection means (52), so that the change in level of light detected by the detection means is proportional to the diameter of the droplet. Preferably two or more intersecting light beams (68,69) are used to provide comparative data about passing droplets.

  • Patent number: 8194970
    Abstract: A method for producing three-dimensionally structured surfaces of objects, the object surface being created as a reproduction of a three-dimensionally structured original surface with the aid of a machining tool. Accordingly, the topology of the original surface is first determined, a measured depth value being assigned to each surface or grid element, creating a depth map of the original surface. The depth values are evaluated in terms of their influence on the reflective properties of the surface elements and the reflective properties are stored in the form of parameters. The depth values are then modified in accordance with the reflective values and are used as topological data for the electronic control of a machining tool.

  • Patent number: 8019123
    Abstract: An estimation unit calculates an estimated motion vector between a first source region of a plurality of source regions and a first destination region on a destination picture. The first destination region has the highest correlation with the first source region. A weight calculation unit searches a plurality of second destination regions. Each second destination region is pointed by the estimated motion vector of another source region adjacent to the first source region. The weight calculation unit extracts pixel values of each second destination region, calculates a difference of pixel values between the first source region and each second destination region, and calculates a weight based on the difference. The weight is smaller if the difference is larger. A filtering unit calculates a motion vector of the first source region by averaging the estimated motion vectors with the weight.
