Abstract: For model predictive control for a spacecraft formation, a method calculates a virtual point that represents a plurality of spacecraft orbiting in a spacecraft formation. The method calculates an outer polytope boundary and an inner polytope boundary relative to the virtual point for a given spacecraft of the plurality of spacecraft. The method maneuvers the given spacecraft to within the inner polytope boundary using model predictive control (MPC) to minimize fuel consumption.

Abstract: A movable platform storage device for off-floor storage including a substantially vertical support member (column) anchored to a concrete floor that defines the deployment axis. The movable platform is connected to the vertical support member (column) and can be raised or lowered to one of any plurality of positions oriented generally transversely to the deployment axis by means of an electric servo-motor power unit and wire cable lifting system. The column is available in different lengths to accommodate ceiling height limitations and desired raised platform heights. The platform storage device can be used as a single stand-alone unit or multiple storage units can be combined in a configuration that creates a unique electric/mechanical powered elevated mezzanine system with increase elevated storage area. The servo motor electric/mechanical wireless power system on each of the combined storage lifts can be programmed identically so that all platforms will raise and lower simultaneously.

Abstract: Apparatus for assembling a pipe-in-pipe pipeline comprises a primary support system, such as an array of rollers, for supporting an outer pipe section and a secondary support system, such as a set of rails, for supporting an inner pipe section. The primary support system supports the outer pipe section centred on a longitudinal axis in common with a trailing end of a partially-completed pipeline. The secondary support system is deployed to support the inner pipe section also centred on that common axis, enabling the inner pipe section to be advanced and welded to an inner pipe of the partially-completed pipeline. The secondary support system is then retracted to advance the outer pipe section, supported by the primary support system, around the inner pipe section. This enables the outer pipe section to be welded to an outer pipe of the partially-completed pipeline.
