Abstract: A rotative electrical connector is provided that allows connection of wires to a movable member so that the member can be moved without disturbing the electrical connection or fatiguing the electrical wire. The connector includes a spherical conductive member attached to the electrical wire and a spherical shell encasing the spherical member, which, in turn, is connected to a second electrical lead. Preferably, a conductive lubricant, such as a conductive grease is inserted into the space between the outer surface of the spherical member and the interior surface of the spherical shell so that there is an electrical connection between the spherical member and the shell. More than one electrical lead can be accommodated by using additional spherical members attached to the additional electrical leads, each of them encompassed in a separate conductive shell, the spherical members and spherical shells being insulated from one another but mechanically connected to one another.

Abstract: A water-skier towrope-handling system is provided that provides an alarm to the driver of a ski towboat when the skier falls. The alarm is triggered by the release of the towrope handle by the skier, independent of the tension on the ski rope. Preferably, a back-up switch is provided that activates the alarm upon contact with the water. The back-up switch is mounted on the towrope in close proximity to the handle assembly to signal the boat driver that the towrope handle assembly is in the water. The monitoring system also provides a tracking system that provides signals to the boat driver of the skier's position relative to the towboat. Preferably, the position indicator is frozen at the time of a fall to indicate the relative position of the skier at the time of the fall to facilitate finding the downed skier. The towrope handling system can also be used to vary the length of the towrope without affecting the action of the alarm and position-monitoring devices.
