A manually operable safety control for use by a diver utilizing an electric motor for propulsion, the safety control serving to automatically prevent an unsafe powered ascent of the diver. This novel safety control comprises a motor control operatively associated with the electric motor, with the safety control utilizing at least a portion of a dive computer interconnected with the motor control. The dive computer has a pressure sensitive device responsive to changes in depth and serving to calculate rate of change of depth, with the computer being operatively connected to the motor control. The motor control is deprived of electric power in the event of the diver ascending too rapidly. In accordance with one embodiment of my invention, the safety control may utilize only the ascent limiter, but another embodiment may also comprise at least one tilt activated switch interconnected with the motor control and serving to automatically prevent an unsafe horizontal operation of the vehicle. The tilt activated switch, upon the vehicle assuming an unsafe horizontal angularity, causes the motor control to deprive the propulsion motor of electric power.
A manually operable safety control for use by a diver utilizing an electric motor for propulsion, said safety control serving to automatically prevent an unsafe powered ascent of the diver, said safety control comprising a motor control operatively associated with said electric motor, said safety control utilizing at least a portion of a dive computer interconnected with said motor control, said dive computer having a pressure sensitive device responsive to changes in depth and serving to calculate rate of change of depth, said computer being operatively associated with means connected to said motor control, latter means causing said motor control to deprive said propulsion motor of electric power in the event of the diver ascending too rapidly.
A manually operable safety control for use by a diver utilizing a vehicle powered by an electric propulsion motor, said safety control serving to automatically prevent an unsafe horizontal operation of the vehicle, said safety control comprising a motor control operatively associated with said electric motor, said safety control utilizing at least one tilt activated switch interconnected with said motor control, said tilt activated switch, upon said vehicle assuming an unsafe horizontal angularity, causing said motor control to deprive said propulsion motor of electric power.
A manually operable safety control for use by a diver utilizing a vehicle equipped with an electric motor for propulsion, said safety control serving to automatically prevent an-unsafe powered ascent of the diver, said safety control comprising a motor control operatively associated with said electric motor,.said safety control utilizing at least a portion of a dive computer interconnected with said motor control, said dive computer having a pressure sensitive device responsive to changes in depth and serving to calculate rate of change of depth, said computer being operatively associated with means connected to said motor control, latter means causing said motor control to deprive said propulsion motor of electric power in the event of the diver ascending too rapidly, said safety control also comprising at least one tilt activated switch interconnected with said motor control and serving to automatically prevent an unsafe horizontal operation of the vehicle, said tilt activated switch, upon said vehicle assuming an unsafe horizontal angularity, causing said motor control to deprive said propulsion motor of electric power.
