Abstract: Clamping devices and associated methods that are useful to develop both axial and circumferential clamping forces in response to a common axial clamping force. The clamp is able to use a simple mechanism to generate both kinds of clamping forces from a single, axial actuating force. The clamping devices of the present invention are particularly useful for clamping cover and base deck components of a hard disk drive enclosure together to allow the components to be joined and sealed together using welding techniques.

Abstract: Technologies are described herein for a power dumper module capable of adapting to power requirements of its implementation. An exemplary adaptive power dumper module includes a power dump circuit configured to dump excess regenerative energy from a load when a voltage at an output to the load exceeds a trip voltage level, and an adaptive circuit configured to select the trip voltage level from a plurality of trip voltage levels based on a bus voltage of a power supply supplying power to the load.
