Abstract: A method of entangling photons in a distributed quantum-based communication system is disclosed which includes generating sets of entangled photon pairs between a plurality of remote nodes (Nodes Ai and Nodes Bi) and a central entangling node (Node C), wherein Nodes Ai and Bi are in both quantum communication and classical communication with Node C, wherein one photon of a first entangled photon pair set is transmitted Node Ai and one photon of a second entangled photon pair set is transmitted to Node Bi, each over the associated quantum channels, and performing Bell-state measurements between the other photon of the first entangled photon pair and the other photon of the second entangled photon pair, such that if the photons arrive at about same time having about same frequency, then the photon pairs are marked as being entangled.

Abstract: A pilot operated hydraulic directional control valve. The hydraulic directional control valve comprises a valve body, a spool, a spring and a control piston. The valve body comprises four top ports and four bottom ports. When a spring force which is applied to a first end of the spool is less than a piston force which is applied to a second end of the spool, the hydraulic directional control valve is in working position. When the spring force is greater than the piston force, the hydraulic directional control valve is in shutdown position.

Abstract: A system for performing hardware-in-the-loop test of a turbine governor. The system includes a hydropower plant simulation subsystem and a signal interface. The hydropower plant simulation subsystem allows for simulating dynamic and kinematic behaviors of components of a hydropower plant. The hydropower plant simulation subsystem includes a memory having processor-readable instructions stored therein and a processor that accesses the memory and executes the processor-readable instructions, which, when executed by the processor configure the processor to perform a method. The method includes generating a plurality of output signals by solving mathematical models of the components of the hydropower plant for a plurality of inputs. The signal interface allows for communicating the plurality of output signals from the hydropower plant simulation subsystem to the turbine governor.

Abstract: A system for calibrating the trip speed of a mechanical overspeed sensing device by manipulating the compression of a spring of the overspeed sensing device. The system may include a rotatable annular mount, on which the mechanical overspeed sensing device is mounted and a trip sensor. The system may drive a rotational movement of the annular mount with a varying speed over time during a test run. The system may designate a rotational speed of the annular device at which the trip sensor is struck by the mechanical overspeed sensing device as a measure trip speed. The measured trip speeds may be determined for various compressions of the spring of an exemplary mechanical overspeed sensing device and based on a desired tripping speed received from a user, a compression value of the spring may be selected for which the closest measured tripping speed to the desired tripping speed is obtained.

Abstract: A photon entanglement system is disclosed which includes a plurality of remote nodes (Nodes Ai and Node Bi) each without a quantum memory; and a central entangling node (Node C) in both quantum and classical communication with the remote Nodes configured to provide photon entanglement therebetween, and includes a first and second broadband photon generators each adapted to generate sets of photon pairs at: i) random times within time-bins, and ii) random frequency bins, wherein one photon of each pair set is transmitted to an associated remote node over quantum channels, and a multiplexed Bell-state analyzer configured to receive another photon of the pair, wherein if the received photons arrive at about same time, then the received photons are marked as being entangled by the controller which communicates the associated time-bin to the associated remote nodes and thereby entangling their associated photons.
