Abstract: A permanent magnet linear motor. The permanent magnet linear motor including a primary comprising a magnetically permeable core having a first face surface on a first side of the core a plurality of teeth forming a plurality of slots on the first side, and a plurality of multi-phase windings wound to have segments thereof in the slots forming a plurality of magnetic poles at each of the first face surfaces; a permanent magnet pair of opposing polarity configured to produce magnetic flux and cause the primary to exert a force on the secondary when the plurality of multiphase windings are excited by a multiphase source; and a passive ferromagnetic secondary adjacent to but spaced from the first face surface, the passive ferromagnetic secondary being moveable with respect to the primary.

Abstract: Disclosed is a pliable bag comprised of a mammal pest barrier resistant to mammal pest passage therethrough. The bag is sized and shaped to receive a ground vehicle, such as an automobile, a truck, a recreational vehicle, farming equipment, construction equipment or the like. Included is establishing access to an interior surface of the bag; by way of this access, moving the ground vehicle into the bag to rest on the interior surface thereof; and while the ground vehicle is resting on the interior surface, closing the bag to envelop the ground vehicle inside the bag and isolate the ground vehicle from mammal pests outside of the bag. In one form, the closure of the bag is provided with a type of zipper.
