Abstract: A vehicle rail system has a frame mountable to a vehicle, the frame having a plurality of support legs, the support legs interconnected via support beams. One or more fixed rails are mountable to the support frame, each fixed rail comprising a plurality of bearings thereon and configured to receive a sliding rail, the sliding rail having a plurality of grooves for receiving the bearings of the fixed rail so as to be slidable thereon. The bearings are located along regular intervals of the fixed rails on each non-mounted side. The sliding rail is then able to slide along the bearings of the fixed rail, extending to the exterior of the frame mounted in the vehicle.

Abstract: A roof-top rail system has a fixed frame mountable to the roof of a vehicle and a moveable frame mounted to the fixed frame. Bearings attached to the frames may engage channels formed in rails of the other frame in a manner such that as the moveable frame slides backward relative to the fixed frame, the moveable frame extends from the back side of the fixed frame. Simultaneously, a back end of the moveable frame rotates down as it extends from the fixed frame to improve access to cargo securing features of the moveable frame.

Abstract: A driver circuit for first and second coils includes first and second selector switches coupled in series between first terminals of the coils and a first common junction, first and second diodes coupled in series between second terminals of the first and second coils, respectively, and a second common junction and a source of first potential coupled to the first common junction. A modulation switch is coupled between the second common junction and a source of second potential. The selector switches and modulation switches are operated to cause currents of controlled magnitude to flow through the coils. The circuit has improved fault immunity whereby at least one coil can be energized even when another coil has been subjected to a chassis ground fault.
