  • Publication number: 20190277463
    Abstract: An LED light fixture is disclosed with an elongated housing that forms a open lower light channel and an upper light channel that is juxtaposed to the open lower light channel with electronics cavity or conduit positioned there between. The open lower light channel includes elongated LED light engines positioned on support edges or structures for emitting indicted and reflected light out from the open lower light channel and the upper light channel includes an elongated LED light engine for emitting light therefrom. The LED light fixture preferably has an elongated reflective insert that extends through the open lower light channel and creates a reflection channel from which the indirect and reflected light is emitted.

  • Publication number: 20190273298
    Abstract: The present disclosure provides systems and methods associated with mode conversion for electromagnetic field modification. A mode converting structure (holographic metamaterial) is formed with a distribution of dielectric constants chosen to convert an electromagnetic radiation pattern from a first mode to a second mode to attain a target electromagnetic radiation pattern that is different from the input electromagnetic radiation pattern. A solution to a holographic equation provides a sufficiently accurate approximation of a distribution of dielectric constants that can be used to form a mode converting device for use with one or more transmission lines, such as waveguides. One or more optimization algorithms can be used to improve the efficiency of the mode conversion.

  • Patent number: 10401493
    Abstract: Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.

  • Patent number: 10400131
    Abstract: The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency.

  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Publication number: 20190263512
    Abstract: A vibration attenuator for a rotor is rotatable about a mast axis and has a frame configured for rotation about the mast axis relative to the rotor. A first mass is axially translatable in a first direction relative to the frame parallel to a first axis, and a first biasing force urges the first mass toward a first-mass rest position in which the first mass is symmetric about the mast axis. A second mass is axially translatable in a second direction relative to the frame parallel to a second axis, and a second biasing force urges the second mass toward a second-mass rest position in which the second mass is symmetric about the mast axis. A selected first or second mass moves radially outward from the rest position to oppose vibrations in the rotor.

  • Patent number: 10386479
    Abstract: Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.

  • Patent number: 10382161
    Abstract: Example devices described herein include endpoint devices which may communicate with an access point device by modulating a channel associated with the wireless communication to encode transmit data. The channel modulation may be performed by utilizing a switch to control an impedance of an antenna at the endpoint device to either reflect or absorb wireless network communication signals received by the endpoint device. The access point device may extract the transmit data by decoding changes in the channel caused, at least in part, by the modulation. Access point devices may transmit a pattern of packets—the presence or absence of which may correspond with transmit data. Endpoint devices may decode this data by using an energy detector to differentiate between the presence or absence of a packet.

  • Patent number: 10372501
    Abstract: Provisioning of computing resources for a workload in a networked computing environment. A method receives a set of provisioning requests in a computer data structure of a networked computing environment, wherein the provisioning requests relate to a workload request. The method further identifies a set of provisioning operations for computing resources in the networked computing environment to perform the provisioning requests. The method determines, for each provisioning operation of the provisioning operations, a respective provisioning time, the respective provisioning time being an amount of time for a particular computing resource to become prepared and equipped to perform a job. The determining the respective provisioning time for each provisioning operation provides a plurality of determined provisioning times.

  • Publication number: 20190200961
    Abstract: A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.

  • Patent number: 10335467
    Abstract: A streamlined method for purifying alpha-1-antitrypsin (AAT) from an AAT-containing protein mixture, such as Coh fraction IV precipitate, is provided. In the method of the invention, contaminating proteins are destabilized by cleavage of disulfide bonds with a reducing reagent, such as dithiol, which does not affect AAT. The destabilized proteins are then preferentially adsorbed on a solid protein-adsorbing material, without the addition of a salt as a precipitante. Spearation of the solid absorbent from the solution leaves a purified AAT solution that is directly suitabale for chromatographic purification, without the need for extensive desalting as in prior art processes. A process incorporating this method, which provides pharmaceutical grade AAT in high yield on a commercial scale, is also described.
