Abstract: A data storage blade includes a plurality of data storage cartridges, with each of the plurality of data storage cartridges comprising at least one data storage medium. The data storage blade also includes shared drive electronics (SDE) external to the plurality of data storage cartridges. The SDE is configured to control data access operations on different data storage cartridges of the plurality of data storage cartridges. The data storage blade further includes a controller-override mechanism activatable to disable communication between the SDE and the plurality of data storage cartridges.

Abstract: An active metasurface includes a number of periodically-repeated unit cells arranged on a substrate that each include a plasmonic waveguide shaped and sized to provide a cutoff mode that captures light of a target wavelength. The active metasurface includes an index modulation controller that controllably varies a voltage differential across each one of the periodically-repeated cells to change a phase of light incident on the metasurface.

Abstract: Features are detected from a sensor signal via a deep-learning network or other feature engineering methods in an edge processing node. Machine-learned metadata is created that describes the features, and a hash is created with the machine-learned metadata. The sensor signal is stored as a content object at the edge processing node, the object being keyed with the hash at, the edge processing node.

Abstract: Method of utilizing a nanochannel in combination with at least one magnetic sensor for detecting (e.g., identifying) molecules, cells, and other analytes. Particularly, the method includes bringing molecules, labeled with magnetic nanoparticles (MNPs), in close proximity to the magnetic sensor to identify the molecules via an output signal from the magnetic sensor. The method is particularly suited for identifying nucleotides of DNA and RNA strands.

Abstract: A system includes a library compartment, a player and a gas generator. The library compartment houses a plurality of data storage disks. The player is external to the library compartment and comprises a head that is configured to interact with at least one of the plurality of data storage disks. The gas generator is fluidly connected to the player. An embodiment includes a partition between the library compartment and player, the partition including a selectively openable interlock. In an embodiment, the player has a negative fluid pressure relative to the library compartment. A method of controlling an environment in a disk player is also described. The method includes detecting a composition of a fluid environment in the disk player and detecting a pressure of the fluid environment in the disk player.

Abstract: A data storage device, and systems thereof, including an actuator arm extending along an actuator axis and one or more rails extending along a rail axis. The rail axis is at an angle to the actuator arm and the actuator arm is movably attached to the one or more rails such that the actuator arm is restricted to linear motion along the one or more rails. Further, the device includes a linear motor positioned adjacent to the actuator arm and adapted to move the actuator arm. In one or more embodiments, the device includes a first actuator arm and a second actuator arm having the distal ends of each connected with at least one head located proximate the connection point.

Abstract: An apparatus includes a detector, a light source configured to emit light, a reflecting apparatus having multiple reflective facets, and a mirror. The reflecting apparatus is configured to rotate around an axis and arranged to reflect the emitted light from the light source and reflect backscattered light. The mirror is arranged to reflect the backscattered light from the reflecting apparatus towards the detector.
