Abstract: The present disclosure relates to devices, circuits, and methods of determining power consumption in an electronic device (e.g., HDD) so that the determined power consumption can be used to determine a concentration of the gaseous oxidizing agent component in an interior gas space of the sealed enclosure and/or actively supply gaseous oxidizing agent component to the interior gas space of the electronic device if the determined power consumption is below a threshold value.

Abstract: A system, apparatus, and method may include receiving edge device data, training a remote artificial intelligence (AI) model using the edge device data, and storing resulting remote AI model parameters in a ledger-based data structure. The ledger may also store device health data indicative of electronic device health of one or more edge devices. A ledger node may store a shared ledger. The shared ledger may use blockchain or encryption techniques and may store encrypted data, data pointers, or transfer data. The shared ledger may be accessible by at least two parties to share particular device health data.

Abstract: A self-loading disc head slider includes first and second raised bearing surfaces having outside bearing edges which diverge from one another along a leg portion which extends from a leading portion to a waist portion of the first and second bearing surfaces. A cavity dam defines a sub-ambient pressure cavity between the first and second bearing surfaces. A leading contour extends from a leading slider edge an intersection with first and second bearing surfaces. A notch is positioned within a central region of the leading contour between the first and second bearing surfaces and has first and second side walls which extend from the leading slider edge to the sub-ambient pressure cavity, through the cavity dam. At least one of the side walls is non-divergent from a longitudinal slider center line at the intersection in a direction from the leading slider edge toward a trailing slider edge.
