Abstract: Provided herein, is an apparatus that includes a fluid dynamic bearing, a hub, and an induction housing. The fluid dynamic bearing is defined by a stationary component and a rotatable component. The hub is configured to rotate relative to the stationary component. A current is induced within the induction housing resulting from the relative rotation. The induced current creates a repulsive force between the stationary component and the hub.

Abstract: Apparatus and method for environmentally monitoring electronics devices. Each electronics device has an environmental sensor configured to monitor an environmental state. Environmental control logic, including computer instructions stored in the memory, is configured to simultaneously query, with respect to a global clock, at least a subset of the electronics devices to read the respective sensors and thereby obtain a set of environmental data points, and to map the set of environmental data points in relation to the sensor locations forming a transmissibility mode profile (TMP).
