A receiver includes two receiving modules, where the first receiving module is extremely parsimonious on battery power and as long as it is successful in developing a proper output signal at a given port maintains the second receiving module off, or substantially off. The vehicle alignment system includes a first telescoping rod having a first base attachable to a hitch of a trailer, and a pair of telescoping rods extending from a cross member with a center magnet attached thereto for attaching to a ball. The heating element is biased against the first plate to provide good heat transfer therewith. One embodiment of the device includes an elongated tubular element that is inserted into the fallopian tube, a grasper that extends out of the tubular element, grasps the interior of the fallopian tube and retracts into the tubular element in a folded bundle of the fallopian tube tissue; and a pusher balloon for pushing a ligating band from the tip of the tubular element onto the tissue bundle. The first apparatus embodiment has a handle with a clip which movably extends over the cup.
