Abstract: An EBA system is provided which includes a primary source of pressurized air, a secondary source of pressurized air, hoses leading the primary and secondary sources of pressurized air to an EBA valve, and two hoses for directing pressurized air to the interior of a protective suit for over-pressurization and to a mouthpiece of a user. The valve is constructed and arranged to operate under two modes of operation, in one of which air from the primary air source is directed to an over-pressurization hose and an inhalation hose while air from the secondary air source hose is blocked, and a second mode in which air from the secondary or auxiliary supply is directed to the inhalation hose but not to the pressurization hose.

Abstract: An auxiliary steering device for outboard motors is disclosed. The auxiliary steering device includes an elongated housing defining a longitudinal axis. A reciprocating moving mechanism is coupled with the elongated housing for movement along a line defined by the longitudinal axis. A motor is coupled with the moving mechanism to reciprocatingly drive the moving mechanism along a line defined by the longitudinal axis. A tie rod is coupled with the moving mechanism and the outboard motor to pivot the outboard motor which, in turn, steers the boat in response to the movement of the moving mechanism along the line defined by the longitudinal axis. A controller is also associated with the motor and a mechanism for limiting movement of the reciprocating moving member along the longitudinal axis is provided to limit movement in both directions along the line defined by the longitudinal axis.
