Abstract: An electrically blowable fuse circuit having a fuse which may be placed in a condition to be blown. The circuit includes a first transistor having a body, a source, a drain, and a gate. The source is connected to one end of the fuse and the drain is connected to ground. The first transistor further includes a controllable parasitic device in its body. A second transistor is connected to the parasitic device such that when the second transistor is turned on, the parasitic device turns on the first transistor, allowing the fuse to be blown when the fuse is placed in a condition to be blown.

Abstract: An extruded vehicle frame part having one or more channels along its length which face inwardly into the vehicle in use, and for connection of interior finishing pieces thereto is described. The frame parts are preferably aluminium or plastic, and the vehicle can be a bus. The present invention provides a simple method of conjoining the interior finishing pieces of a vehicle such as a bus to the frame structure. The present invention obviates the need for additional bolts or glue which traditional fitting require. The present invention also avoids the need for holes or apertures be created in the frame parts to receive e.g. bolts.
