Abstract: A weight sensor includes a plurality of load cells. A first load cell is configured to produce a first electric current based on a force experienced by the first load cell. A second load cell is configured to produce a second electric current based on a force experienced by the second load cell. A third load cell is configured to produce a third electric current based on a force experienced by the third load cell. And a fourth load cell is configured to produce a fourth electric current based on a force experienced by the fourth load cell.

Abstract: An example network device includes a primary node and a standby node. The primary node includes one or more processors implemented in circuitry and configured to execute an operating system providing an application space and a kernel space, execute a replication application in the application space to receive a write function call including data to be written to a socket of the operating system and to send a representation of the data to a replication driver executed in the kernel space, execute the replication driver to send the representation of the data to a replication module executed in the kernel space, and execute the replication module to send the representation of the data to the standby node and, after receiving an acknowledgement from the standby node, to send the data to the socket.

Abstract: The techniques include communicating a plurality of TCP data segments from different TCP connections as a single TCP data segment via a TCP gateway connection. For example, network host devices of autonomous systems may ordinarily transfer TCP data segments across dedicated TCP connections. An Autonomous System Boundary Router (ASBR) on one end of the TCP gateway connection may intercept TCP data segments from different TCP connections and may append the TCP data segments as a single appended TCP data segment and communicated via the TCP gateway connection. An ASBR on the other end of the TCP gateway connection may separate TCP data segments from the appended TCP data segment and determine, based on connection flow information, the TCP connections associated with each of the separated TCP data segments. The ASBR may then forward the separated TCP data segments to their original destinations.

Abstract: A process for production of self-assembled quantum dots is described which does not entail any processing steps before or after growth of the quantum dots. The process uses in situ formation of three dimensional islands which occurs during epitaxy of material with a different lattice parameter than the substrate. Further deposition of the substrate material then produces single or multiple buried two dimensional layers of randomly distributed or selectively positioned and substantially uniform sized quantum dots. These layers are free of defects and interface states. The lateral dot diameters vary between 140 to 300 Angstroms by appropriate choice of deposition parameters.
