US10594743B2 Method, apparatus, and system for implementing a content switch
Some embodiments provide a novel content switching method that distributes requests for different types of content to different sets of content servers. In some embodiments, the method deploys a content switch in the ingress data path of a first content server that is part of a first set of servers that processes requests for a first type of content. This content switch receives each content request that is directed to the first content server, and determines whether the received request is for the first content type that is processed by the first content server.

When the second set of servers includes two or more servers, the content switch in some embodiments performs a load balancing operation to distribute the load amongst the servers in the second set. For each request, the load balancing operation in some embodiments selects one server from the second server set based on a set of load balancing criteria that specifies one manner for distributing the requests among the servers of the second set, and then forwards the request to the selected server.

US10593879B2 Quantum information processing with majorana bound states in superconducting circuits
In a weak link of two s-wave superconductors (SCs) coupled via a time-reversal-invariant (TRI) topological superconducting (TSC) island, a Josephson current can flow due to Cooper pairs tunneling in and out of spatially separated Majorana Kramers pairs (MKPs), which are doublets of Majorana bound states (MBSs). The sign of the resulting Josephson current is fixed by the joint parity of the four Majorana bound states that make up the MKPs on the TSC island. This parity-controlled Josephson effect can be used as a read-out mechanism for the joint parity in Majorana-based quantum computing. For a TSC island with four terminals, the SC leads can address a Majorana superconducting qubit (MSQ) formed by the charge ground states of the TSC island's terminals.

US10593813B2 Vertical rectifier with added intermediate region

The present application teaches ways to combine and optimize these two structures in a merged device so that the resulting combined structure achieves both a low forward voltage and a high reverse breakdown voltage in a relatively small area. In one class of innovative implementations, an insulated (or partially insulated) trench is used to define a vertical channel in a body region along the sidewall of a trench, so that majority carriers from a “source” region (typically n+) can flow through the channel. An added “pocket” diffusion, of the same conductivity type as the body region (p-type in this example), provides an intermediate region around the bottom of the trench. This intermediate diffusion, and an additional deep region of the same conductivity type, define a deep JFET-like device which is in series with the MOS channel portion of the diode. This advantageously permits the MOS channel portion to be reasonably short, and to have a reasonably low threshold voltage, since the high-voltage withstand characteristics are defined by the deep JFET-like device.

The solar cell front side silver paste doped with modified graphene comprises by weight 0.1-5 parts of modified graphene, 88-91 parts of silver powder, 5-15 parts of organic binder, 1-5 parts of organic solvent, 1-3 parts of glass powder, wherein the modified graphene is a surface modified graphene. A solar cell front side silver paste is developed, which is screen printed on a crystalline silicon wafer, sintered at a high temperature, penetrates the SiNx passivation layer in the crystalline silicon wafer, and thus forms a good ohmic contact.
US10593433B2 Device for securing a blanket module to a fusion reactor vacuum vessel
The invention relates to the field of thermonuclear fusion and can be used for securing a blanket module to a vacuum vessel of a fusion reactor. The connecting device comprises a flexible support in the form of rods mounted between an upper flange having a concave spherical surface and a lower flange; a displacement compensator mounted on the upper flange; and a male-threaded locknut. The displacement compensator is fixedly connected to the blanket module and comprises a locking screw and a supporting sleeve, which are pivotally interconnected, a spacer sleeve, and a coupling sleeve with a spherical protuberance. The spacer sleeve is movably connected to the locking screw and pivotally connected to the upper flange of the flexible support and to the spherical protuberance of the coupling sleeve. The coupling sleeve is fixedly connected to a stop surface of the locknut.
