DESCRIZIONE
The present invention relates to motor safety devices as used in increasing numbers for the killing (stopping) of engines and motors or disengaging propulsion units from engines and motors, when there are no operators to maintain control of an apparatus or vehicle such as jet-ski, boat, go-kart and the like or personnel to oversee use of a motorised tool or the like. In particular the present invention relates to the control and use of such systems. Motor boat operators on a boat have been known to fall overboard without being detected by the operator of the boat. In such cases, the person Is often lost or is drowned before being found. In addition, sole operators of boats have fallen overboard resulting in the boat continuing its operation without an operator. Such runaway boats have been known to seriously injure the operator of the boat in the water since a runaway boat tends to circle back to the place where the operator has fallen overboard. Such injuries are normally caused by the propeller of the boat cutting the operator in the water, or by the boat itself ramming the operator In the water. The present invention is also applicable to other types of equipment such as motorised gymnasium equipment, hand operated power tools, such as agricultural and arboriculturist equipment and wood working tools. The present Invention seeks to provide a solution to such problems
