Abstract:
Systems and methods to generate virtual spot beams are provided. The system includes a first antenna that provides a first physical spot beam that represents a radio frequency (RF) signal received from a remote source. The system also includes a second antenna that provides a second physical spot beam that represents the RF signal received from the remote source. The system further includes a beam formation module that is communicatively to the first and second antennas and that performs a beam formation operation on the first and second physical spot beams to generate one or more virtual spot beams.

A polymeric flexible substrate that meets the barrier requirements for oxygen and water, while exhibiting thermal stability or transparency may be formed from functionalized graphanes bonded with polymers.
Abstract:
A method for providing an augmented reality includes capturing a real image from information contained in a visible light; generating a virtual image from the captured image; displaying on an augmented reality device a view selected from the group consisting of the real image and the virtual image; displaying the view of the real image in response to detection of a motion; and displaying the view of the virtual image in the absence of detected motion. An augmented reality device and a computer program product are disclosed.
Abstract:
Polymeric barriers for organic light emitting diodes are formed in-situ by encapsulation or polymerization. Encapsulation with melamine-cyanurate is performed using sublimation reaction technique. An encapsulation technique involves curing a layer of resin made by mixing a polyaza aryl compound, such as melamine, melam, or melem, with a cyanuryl triglycidyl ether. Another encapsulation technique involves curing a layer of resin made by mixing the polyaza aryl aromatic compound in 2,4,6-tricyanatophenyl glycidyl ether or tetracyanatobenzene applied to an organic light emitting diode. Photo catalytic curing of the coating may be achieved in the presence of catalysts such as titanium IV oxide acetylacetonate.
Abstract:
In some embodiments, a light-emissive device may include a reflector assembly, a dielectric layer, an electrode pin, a second semiconductor, and an electrode connector. The reflector assembly may define a cavity, a light opening, and an electrode pin opening. The dielectric layer may be positioned adjacent to the reflector assembly. The dielectric layer may define an electrode pin aperture and an electrode connector aperture. The electrode pin may include a head and a shaft. The head may be positioned in the cavity and coated with a first semiconductor. The shaft may be at least partially positioned in the electrode pin opening and through-mounted to the electrode pin aperture. The second semiconductor may be disposed in the cavity. The second semiconductor may surround the first semiconductor. The electrode connector may be electrically coupled to the second semiconductor and through-mounted to the electrode connector aperture.
Abstract:
Techniques described herein generally include methods and systems related to circuit switching in a network-on-chip. According to embodiments of the disclosure, a network-on-chip may include routers configured to pre-reserve circuit-switched connections between a source node and a destination node before requested data are available for transmission from the source node to the destination node. Because the circuit-switched connection is already established between the source node and the destination node when the requested data are available for transmission from the source node, the data can be transmitted without the delay or with reduced delay caused by setup overhead of the circuit-switched connection. A connection setup message may be transmitted together with a memory request from the destination node to facilitate pre-reservation of the circuit-switched connection.
Abstract:
Techniques described herein are generally related to retrieval of data in computer systems having multi-level caches. The multi-level cache may include at least a first cache and a second cache. The first cache may be configured to receive a request for a cache line. The request may be associated with an instruction executing on a tile of the computer system. A suppression status of the instruction may be determined by a first cache controller to determine whether look-up of the first cache is suppressed based upon the determined suppression status. The request for the cache line may be forwarded to the second cache by the first cache controller after the look-up of the first cache is suppressed.
Abstract:
Technologies are generally described for a failure recovery scheme for a cloud system. In some examples, the cloud system may include one or more computing nodes, and one or more network switches configured to relay one or more packets among the one or more computing nodes. A respective one of the computing nodes may include a first processor configured to process the one or more packets to communicate with at least one of the network switches, and a second processor configured to process the one or more packets to communicate with at least one of the other computing nodes in the cloud system.
Abstract:
Filtration systems and methods for removing a filter residue from a filter employed in filtering a liquid (for example, grey water). The filtration system may include a vessel having an inlet through which a liquid can be introduced during use and an outlet through which filtered clean liquid can exit. A filter configured to filter the liquid is disposed within the vessel between the inlet and the outlet. The filtration system may further include at least one transducer disposed on or adjacent to the filter. The at least one transducer may be configured to generate one or more pressure waves effective to dislodge at least some residue materials collected on an upstream side of the filter.
