Abstract: Methods for analysis of the magnetic grain using a software program effectively and accurately by improving the magnetic grain boundary contrast from an image prior to analyzing the grain size with an imaging analysis program. A method for automated grain size analysis includes obtaining a SEM electronic image of a magnetic material composed of a plurality of grains and modifying the image by smoothing the image, removing high spatial and low spatial frequencies from the image, improving contrast of the image, pixelating the image, processing the image to a binary image, and clearing outer edges of the binary image to remove at least incomplete grains to generate grain size data from the image.

Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a shared controller adapted to removably couple with each of a plurality of storage cartridges. Data blocks within primary non-volatile memory of the cartridge-based storage system collectively comprise a main store with information-theoretic security. The shared controller incorporates various controls for providing selective data access to individual data magazines and/or cartridges as well as for partitioning user data and writing the partitioned data according to an information-theoretic security scheme and reading the partitioned data and reconstructing the user data from the partitioned data.

Abstract: Evolving function secret sharing is performed on a given function by multiple share parties, A dealer selects a random vector for each share party corresponding to an arrival order. The dealer generates an array of function shares for each share party of the set, each array including a function share based on the random vector corresponding to the share party and one or more function shares cryptographically generated based on the random vector corresponding to each previously-arrived share party. The dealer distributes an array of the function shares to each share party, wherein a first function share result resulting from a computation of a first function share on given input data and at least a second function share result resulting from a computation of a second function share on the given input data are combinable to yield a result of the given function executed on the given input data.

Abstract: An apparatus includes a data storage disc having a read/write surface, and an arm extending along an arm axis and having a head end that supports a head that is configured to interact with the read/write surface. The apparatus also includes a rail extending along a rail axis that is normal to the arm axis, and a carriage coupled to the arm and movably coupled to the rail. The apparatus further includes a latch mechanism configured to releasably hold the carriage to the rail at a fixed position.

Abstract: A data storage system may store a first data block having a first data configuration generated by a host in a non-volatile memory that is connected to a data module. A data strategy may be generated with the data module in response to the storage of data with the data strategy consisting of at least one trigger associated with identifying the first data block as hot. The first data block can be replicated to a different memory location with a second data configuration as directed by the data strategy with the first data configuration being different than the second data configuration.

Abstract: The slow speed of conventional selective electroplating and L-PED (and further requirement of a series of masks in the case of selective electroplating) necessary to generate a metallic three-dimensional object makes conventional selective electroplating and L-PED not viable for mass manufacturing metallic three-dimensional objects. The presently disclosed technology generally utilizes electroplating and L-PED technologies with a screen electroplating process. The screen electroplating process disclosed herein is capable of achieving a faster throughput and a lower workpiece temperature than traditional 3D printing processes can provide, particularly traditional metal 3D printing processes. As a result, the presently disclosed screen electroplating process is able to achieve much faster results in printing a complex three-dimensional metallic structure using electroplating.

Abstract: A data storage system can have a hardware interposer connected inline between a plurality of controllers and a plurality of memories. A bus of the hardware interposer may be monitored with a security breach monitor of the hardware interposer to allow a deviation from a predetermined address range to be detected by the security breach monitor, which prompts the security breach monitor to block access through the hardware interposer for a first controller of the plurality of controllers.

Abstract: A data storage system may have a plurality of memory cells located in different data storage devices that are arranged into a plurality of logical namespaces with each logical namespace configured to be sequentially written and entirely erased as a single unit. An asymmetry strategy may be proactively created with the asymmetry module in response to data access activity to the logical namespaces by the asymmetry module. A new mode, as prescribed by the asymmetry strategy, is entered for at least one logical namespace in response to an operational trigger being met. The new mode changes a timing of at least one queued data access request to at least one logical namespace.
