Abstract: An active shock-absorbing boat seat system has a seat system mounted to the boat deck through an active shock absorber. Sensors monitor both the shock to be passed from the deck to the seat as well as the shock actually received by the seat after passing through the shock absorbing system. A controller monitors the shock levels and provides a continuing control signal to the shock-absorbing unit to control the response of the shock-absorbing unit during the duration of the shock. The control system can provide for adjustment of various operating parameters for the system, including initial position of the seating system, overall ride stiffness, maximum allowable shock, and other parameters.

Abstract: A seating system especially well adapted for use in high-speed and high-performance water craft provides improved support for a user, in both standing and sitting positions. The seating system includes a fixed base upon which is mounted a frame positionable and lockable in a chosen forward/aft position. The frame supports independent backrest and seat units, each of which is independently vertically positionable along the frame. The seat unit further includes bolster and seat portions which are pivotable between a first position in which the seat portion is operative and a second position in which the seat portion hangs downwardly, in an inoperative orientation, and where the bolster provides support for the standing occupant.

Abstract: An improved boat seat includes an adjustable footrest and an integral steering control mounted to an armrest. The footrest is height-adjustable, and is pivotable between operative and retracted positions at any chosen height. The steering control is mounted to the distal end of the armrest, and is at least partially embraced and covered by an armrest pad.

Abstract: A muscle exercise and/or rehabilitation apparatus includes a fixture against which a force can be applied; a sensor which senses the force applied to the fixture and produces a load signal corresponding thereto; a speed detector which produces a velocity signal corresponding to the speed of the fixture; a servo motor which produces a rotational output of an output shaft thereof; a closed loop servo circuit which controls the motor in response to the load signal and the velocity signal to control rotation of the output shaft of the servo motor; and a conversion device connected between the fixture and the output shaft of the servo motor for translating the rotational output of the output shaft to linear motion of the fixture, the conversion device including a frame formed by a base, two spaced vertical support bars extending upwardly from the base, and an upper cap securing upper ends of the vertical support bars together, two vertical guide rods supported by the frame, a slide movable along the guide rods in

Abstract: A back attachment for a muscle exercise and/or rehabilitation apparatus of the type having a motor driven output shaft with a central axis, includes seat for supporting a person thereon; a back exercising frame connected to the output shaft for pivoting the back of the person about the central axis when the person is seated in the seat; a support stand for fixedly supporting the seat at a downward angle of approximately 15 degrees toward a front portion of the seat, regardless of the angle of pivot of the back exercising frame; securing straps for securing the person to the seat and back exercising frame; an adjustable foot rest connected to the seat for supporting the feet of the person, during pivoting the back exercising frame, the adjustable foot rest being adjustable along the length thereof toward and away from the seat; a lumbar support connected with the back exercising frame for supporting the lumbar region of the person about an axis offset from the central axis, during pivoting movement of the back

Abstract: An apparatus for controlling the pressure in a tracheal cuff used with a tracheal tube to seal the walls of the trachea with respect to the tube, the cuffed tracheal tube being of the type used with an automatic respirator which cycles between an inhalation mode and an exhalation mode.

Abstract: A thermodilution injection system comprising a syringe for delivering a measured amount of injectate in an accurately predetermined time period, and an injectate cooling device positioned in serial relation to the syringe for cooling the injectate when it is dispensed from the syringe.

Abstract: A thermodilution injector is presented in which a pneumatically powered piston operates the plunger of a syringe to deliver a measured amount of injectate in an accurately predetermined time period.

Abstract: A reciprocating infusion pump is presented having a pair of syringes activated by individual actuating cylinders. The actuating cylinders are interconnected with a hydraulic fluid, and the cylinders and alternately pneumatically actuated whereby the cylinders alternately act as drive and follower cylinders whereby one syringe delivers fluid to a patient while the other is refilled from a reservoir. A directional adapter set is affirmatively actuated in synchronism with the actuating cylinders to control the direction of fluid flow from the reservoir to the syringes and from the syringes to the patient.

Abstract: A waste disposal system for a boat equipped with a head and a waste-holding tank for receiving sewage therefrom. A dual deck fitting and associated equipment permits conventional dockside pumpout of the holding tank and also permits overboard dump of the contents of the tank. The dual deck fitting is provided with a pair of plugs, one of which embodies a pivotable handle which facilitates threading and unthreading of the plug in the deck fitting and also a lug which engages a slot in the other plug to facilitate threading and unthreading of the latter plug in the deck fitting.
