  • Publication number: 20190255767
    Abstract: A method of fabricating an object, comprising depositing a first layer of first object material on a support substrate electrode; applying a conductive agent material onto the first layer; depositing a first layer of charged powder on an intermediate substrate; conveying the first layer of charged powder on the intermediate substrate proximate to the first layer of first object material; and applying a transferring electric field to cause transfer of the first layer of charged powder from the intermediate substrate onto the first layer on the support substrate electrode, to form a first powder layer on the first layer on the support substrate electrode. Multiple powder layers may be deposited on the first layer. The method may be further comprised of fusing the powder layer(s) to form a first fused layer on the support substrate electrode. A related object fabrication apparatus is also disclosed.

It also relates to enabling multi-user collaboration and interaction in an immersive virtual environment. In particular, it relates to capturing different sceneries of a shared real world space from the perspective of multiple users. The technology disclosed further relates to sharing content between wearable sensor systems. In particular, it relates to capturing images and video streams from the perspective of a first user of a wearable sensor system and sending an augmented version of the captured images and video stream to a second user of the wearable sensor system.

  • Patent number: 10090702
    Abstract: Reconfiguring a power system for an electrical load includes establishing a secondary feed to an electrical load that is receiving power from a primary power source. A set of secondary feed lines is coupled between a donor power source and a power input to the electrical load such that the set of secondary feed lines is configured to supply power from the donor power source to the electrical load. An automatic transfer switch is coupled in parallel with the set of secondary feed lines. The electrical load is transferred by the automatic transfer switch from the donor power source to the primary power source for the reconfiguration.

  • Publication number: 20180179153
    Abstract: A process for preparing diaryl sulfones, such as 4,4?-dichlorodiphenylsulfone is disclosed. The process comprises contacting an aryl compound with sulfur trioxide to provide a benzene sulfonic acid. The benzene sulfonic acid is coupled to additional aryl compound in the presence of a catalyst. During the coupling step, the additional aryl compound is continuously added while water is removed.

  • Publication number: 20180039307
    Abstract: An air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

  • Publication number: 20170208037
    Abstract: A method and system for providing Deep Packet Inspection (DPI) as a service to a computer network are provided herein. The contribution of embodiments of the present invention is two-folded. First, a possible framework of having DPI deployed as a service is detailed, including the necessary algorithms and required adaptations. Second, the superior performance of the suggested design is demonstrated via simulations. Since the focus is on the algorithmic aspects and network design, an SDN implementation of the suggested design is not provided herein. However, many aspects of such an SDN implementation follow closely the guidelines known in the art.

  • Patent number: 8887026
    Abstract: A method for error detection includes storing in an associative memory multiple data entries, each data entry including a data item together with one or more check symbols computed with respect to the data item. A predetermined sequence of search keys is applied to the memory, thereby causing the memory to generate, in parallel, match results with respect to the data entries. The match results are processed in order to identify an error in at least one of the data entries.
