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: An apparatus and method for reducing structural vibrations in a disc drive that incorporates a fusible alloy. A fusible alloy portion is constrained between a first and second structural alloy portion through conventional lamination techniques. A fusible alloy can be incorporated into any structural component of the disc drive, including a base plate and an information storage disc. Fusible alloys incorporated into the disc drive absorb energy transmitted by vibrations through anelastic deformation, i.e., through dislocation motion. Suitable fusible alloy materials may include but are not limited to: Lead-Tin, Indium-Tin and Indium-Bismuth.
