Abstract: A method of treating a metal carbonate salt includes hydrolyzing a metal halide salt to form a hydrohalic acid and a hydroxide salt of the metal in the metal halide salt. The metal includes an alkaline earth metal or an alkali metal. The method includes reacting the hydrohalic acid with the metal carbonate salt, wherein the metal carbonate salt is a carbonate salt of the alkaline earth metal or alkali metal, to form CO2 and the metal halide salt. At least some of the metal halide salt formed from the reacting of the hydrohalic acid with the metal carbonate salt is recycled as at least some of the metal halide salt in the hydrolyzing of the metal halide salt to form the hydrohalic acid and the hydroxide salt.

Abstract: A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing defining a passageway, and a connector body having a first end and a second end positioned opposite the first end, with the connector body having a connection member configured to be secured to a mating connector. One of the housing and the connector body includes a tab and the other of the housing and the connector body defines a channel that receives the tab, with the connector body movable relative to the housing between a first position where the connector body is restricted from rotating relative to the housing in a first rotational direction and free to rotate relative to the housing in a second rotational direction, and a second position where the connector body is free to rotate in the first and second rotational directions.

Abstract: Described apparatuses and methods facilitate bus training with multiple dice, such as multiple memory dice. A controller can communicate with multiple dice to perform bus training by sending a test pattern and receiving in return a feedback pattern indicative of the bits detected by the dice. Because suitable signal timing can differ between dice, even those using the same bus, a controller may train each die separately from the others. In some situations, however, individualized training may be infeasible. To accommodate such situations, logic associated with two or more dice can combine, using at least one logical operation, bits as detected from the test pattern into a combined feedback pattern. A timing parameter that is jointly suitable for multiple dice can be determined, and the bus training may be concluded, responsive to the combined feedback pattern matching the test pattern. The multiple dice may be stacked or linked.

Abstract: Described apparatuses and methods relate to adaptive memory registers for a memory system that may support a nondeterministic protocol. To help manage power-delivery networks in a memory system, a device includes logic that can write values to memory registers associated with memory blocks of a memory array. The values indicate whether an associated memory block has been refreshed within a refresh interval. Other logic can read the registers to determine whether a block has been refreshed. The device also includes logic that can access data indicating a row address that was most recently, or is next to be, refreshed and write values representing the address to another register. The register can be read by other logic to determine whether a wordline potentially affected by an activation-based disturb event is near to being refreshed. These techniques can reduce the number of refresh operations performed, saving power and reducing costs.

Abstract: Techniques are provided for repairing a primary slice file, affected by a storage device error, by using one or more dead replica slice files. The primary slice file is used by a node of a distributed storage architecture as an indirection layer between storage containers (e.g., a volume or LUN) and physical storage where data is physically stored. To improve resiliency of the distributed storage architecture, changes to the primary slice file are replicated to replica slice files hosted by other nodes. If a replica slice file falls out of sync with the primary slice file, then the replica slice file is considered dead (out of sync) and could potentially comprise stale data. If a storage device error affects blocks storing data of the primary slice file, then the techniques provided herein can repair the primary slice file using non-stale data from one or more dead replica slice files.

Abstract: Described apparatuses and methods facilitate bus training with multiple dice, such as multiple memory dice. A controller can communicate with multiple dice over a bus to perform bus training by sending a test pattern and receiving in return a feedback pattern indicative of the bits detected by the dice. Because suitable signal timing can differ between dice, even those using the same bus, the controller may attempt to train each die separately from the others. In some situations, however, individualized training may be infeasible. To accommodate such situations, logic associated with two or more dice can combine the bits as detected from the test pattern into a combined feedback pattern. A timing parameter that is jointly suitable for multiple dice can be determined, and the bus training may be concluded, responsive to the combined feedback pattern matching the test pattern. The multiple dice may be stacked or linked.

Abstract: An atom trap integrated platform (ATIP) comprises a substrate, a membrane, and a suspended waveguide. The substrate has an opening formed therein. The membrane extends across a portion of the substrate opening. The suspended waveguide is formed on the membrane such that the suspended waveguide extends from a first edge of the substrate to a second edge. A magneto-optical trap (MOT) is formed around the suspended waveguide by emitting a plurality of cooling beams and a repump through the substrate opening. Evanescent fields are established above the suspended waveguide by coupling two trapping beams through the suspended waveguide, which trapping beams are red-detuned and blue-detuned with respect to the resonant optical transition of the atoms. By forming the MOT within the evanescent fields, an evanescent field optical trap (EFOT) is formed.

Abstract: A joint decorticator instrument configured for single use. The joint decorticator has a metal rod affixed within a polymer sheath. The polymer sheath has a longitudinal channel configured to receive an alignment protrusion with a working channel for maintaining the joint decorticator in a proper alignment relative to the working channel. The joint decorticator may include an integrated extraction mechanism involves an extraction lever pivotally connected to the handle portion of the polymer sheath. The extraction lever has an eccentric cam mechanism. When the extraction lever is pivoted toward an open position, the cam exerts a force onto a collar of the working channel and an opposite force on the connector pin that pivotally connects the extraction lever to the polymer sheath, thereby dislodging the abrading head of the joint decorticator from the joint.
