Self-prioritizing adaptive retry threshold adjustment
Exemplary methods and apparatus are provided for read recovery in solid state devices (SSDs) with non-volatile memories (NVMs). In some examples, a dynamic priority read retry table (PRT) is generated for use with a static read retry table (RRT). In one aspect, a most recent successful read retry entry is determined from among the entries in the RRT. The most recent successful read retry entry is inserted as a first priority read retry entry within the PRT. A subsequent read recovery operation is performed using the first priority read retry entry of the PRT. In some examples, one or more neighboring values are selected for each entry in the PRT starting with the newest entry and proceeding chronologically to the oldest entry. The use of the PRT may help address die-to-die variations, block-to-block variations, or the transient changes that may occur in device physics within NVMs. |

Data migration using write protection
Techniques are presented for implementing non-host-based migration in a manner that is not subject to certain types of data corruption. This may be accomplished by preventing any hosts from having write access to a target LUN until it can be confirmed that all applications that access a source LUN have been shut down. This arrangement prevents accidentally writing to the target LUN while the source LUN is still being accessed. As a further precaution, just in case the confirmations are incorrect, a target data storage system can direct a source data storage system to remove access to the source LUN from all of the hosts, which has a similar effect. The migration can then proceed. |

Push-pull compressor having ultra-high efficiency for cryocoolers or other systems
An apparatus includes a first piston and an opposing second piston, where the first and second pistons are configured to move inward to narrow a space therebetween and to move outward to enlarge the space therebetween. The apparatus also includes a first voice coil actuator having (i) a first voice coil connected to the first piston and (ii) a first magnet connected to the second piston. The apparatus may further include a second voice coil actuator having (i) a second voice coil connected to the second piston and (ii) a second magnet connected to the first piston. Each voice coil actuator may be configured to apply equal and opposite forces on or against the first and second pistons. |

Isolated chamber pump with recirculation of leakages
Vibrating pump with a secondary closed circuit designed for the recovery and reinjection of the fluid that can eventually escape from the compression chamber and which, if not collected, would end up in the force chamber affecting the drive elements (springs, magnetic core) and therefore the proper functioning and useful life of the pump. |

High torque, low RPM horizontal axis wind turbine
A horizontal axis wind turbine which includes a plurality of blades that rotate at relatively low rpms and produce a high torque to rotate a generator is described. The wind turbine provides more power at low to moderate wind speeds than conventional wind turbines, produces more power at low wind speeds while still operating at high wind speeds, begins generating power at very low wind speeds, produces less noise, and reduces animal (e.g., bird and bat) collisions. The method determines the number of blades for the wind turbine based upon the desired rpm for the wind rotor and the generator configuration is based upon the estimated torque generated by the number of blades. |

Methods for manufacturing spar caps for wind turbine rotor blades
The present disclosure is directed methods for manufacturing spar caps for wind turbine rotor blades. In certain embodiments, the method includes forming an outer frame of the spar cap via at least one of three-dimensional (3D) pultrusion, thermoforming, or 3D printing. As such, the outer frame has a varying cross-section that corresponds to a varying cross-section of the rotor blade along a span thereof. The method also includes arranging a plurality of structural materials (e.g. layers of pultruded plates) within the pultruded outer frame of the spar cap and infusing the structural materials and the outer frame together via a resin material so as to form the spar cap. The resulting spar cap can then be easily incorporated into conventional rotor blade manufacturing processes and/or welded or bonded to an existing rotor blade. |

Variable displacement pump-motor
A variable displacement pump-motor includes a pump-motor having a plurality of cylinders and pistons, and further including a main shaft rotatable relative to the system body. A hydro mechanical control system includes a plurality of main stage valves in communication with the plurality of cylinders. Each of the main stage valves is configured to open and close a cylinder of the plurality of cylinders to one or more of high or low pressure fluid sources. A pilot spool valve is in selective communication with each of the main stage valves. The pilot spool rotates with the main shaft. The pilot spool includes coding configured to operate each of the main stage valves to open and close the respective cylinders to the one or more high and low pressure fluid sources according to a translational position of the pilot spool and rotation of the pilot spool by the main shaft. |

Hydrostatic pressure turbines and turbine runners therefor
Hydrostatic pressure turbine runners according to the present disclosure are designed for maximally exploiting the hydrostatic pressure of a flowing fluid, rather than maximizing extraction of kinetic energy from the flow. The design converts less kinetic energy of the flow into hydropower as compared with current run-of-river turbine runner technologies. However, hydrostatic pressure turbine runners according to the present disclosure convert substantially more potential energy into hydropower. As a result, the total amount of energy converted into hydropower is significantly higher than the hydropower available from conventional run-of-river turbine runner designs, and, without promising any particular utility, may be capable of surpassing the upper limit of converted energy as defined by Betz' law. In a run-of-river context, the total amount of converted energy—mainly converted potential energy—may surpass the amount of kinetic energy of the flow engaged by the turbine runner. |
