Abstract: A portable container includes flexible walls defining an interior compartment and a support feature within the interior compartment providing a surface to support an item within the interior compartment, where the item is suspended above a wall. In at least some implementations, one of the walls is a lower wall and the support feature holds the item above the lower wall. In other implementations, a container includes a plurality of walls connectable together to define an interior compartment. At least two separate walls are selectively movable to and from open and closed positions. One movable wall is an upper wall and another movable wall is a wall adjacent to the upper wall. This permits, for example, items to be loaded into and unloaded from the container both through the top and through a front, rear or side wall.

Abstract: A control system for and method of controlling a switched reluctance generator to maintain stable control of the generator in the continuous current mode. This is achieved by sensing the load on the generator, the speed of the rotor and the position of the rotor with respect to each phase winding in order to derive switching command signals to maintain the volt-seconds applied to the winding in each phase period so as to inhibit progressive flux growth in the phase windings by actuation of the controller switches.

Abstract: A switched reluctance motor has groups of adjacent poles of the same polarity. A starting magnet is fitted to one side of one or more of the poles in one or more of the groups. The polarity of the magnet can be the same as that of its host pole. The starting magnet influences the rest position of the rotor when it is not being driven so that the rotor will not be in an orientation such that it will not start when the stator poles are energized.

Abstract: An electric motor comprises a laminated stator core supporting windings to define similar adjacent poles. A rotor is mounted to rotate within the stator. The similar poles in a group define flux paths with adjacent pole groups. Thus the flux paths required are restricted to those between adjacent dissimilar pole groups. In this way the material of the core between the flux paths can be reduced as it is not required to carry flux itself. This redundant portion of the core can be shaped to accommodate neighbouring components or to reduce the material of the core laminations.
