Abstract: Some embodiments include a privacy/security apparatus for a portable communication device that includes a housing assembly configured to at least partially attenuate at least one of sound energy, acoustic energy, and electromagnetic energy including light, optical, and IR energy and RF radiation from passing through the housing assembly. The housing assembly includes a Faraday cage with two or more portions, and at least one protective shell coupled to or forming at least one aperture. The at least one aperture is configured and arranged to at least partially enclose the portable communication device so that at least a portion of the portable communication device is positioned within at least one portion of the Faraday cage, and the at least one seal coupled or integrated with the protective shell. The housing assembly can be an articulating assembly, a sliding assembly, and can include an active acoustic jamming or passive acoustic attenuation element.

Abstract: A method for assembling parts. A sealant is placed between a plurality of parts in a stack up to form a workpiece. The workpiece is clamped using a permanent magnet unit and an electromagnetic clamping device in an activated state such that a number of forces caused by a magnetic field clamps the workpiece between the electromagnetic clamping device and the permanent magnet unit. A number of holes are drilled in the workpiece. A number of fasteners are installed in the number of holes.

Abstract: An apparatus may comprise a permanent magnet unit, an end effector, and an electromagnetic clamping device. The end effector may be capable of performing workpiece operations. The electromagnetic clamping device may have an activated state and a deactivated state.

Abstract: An electromagnetic clamping system contains a housing, numerous permanent magnets, numerous low friction surfaces having a number of wheels, an end effector, an electromagnetic clamping device, first, second, and third coil systems, and a core. The end effector performs operations on a workpiece. The electromagnetic clamping device has an activated state and a deactivated state. The electromagnetic clamping device further includes a first coil system generating a first magnetic field causing normal forces on the permanent magnet unit and the clamping device; a second coil system generating a second magnetic field causing side forces on the permanent magnet unit; and a third coil system generating a third magnetic field causing a rotational force on the permanent magnet unit. The core provides access to the workpiece surface for performing operations thereon; and concentrates forces from a number of magnetic fields on the core surface contacting the workpiece surface.
