Abstract: A flex button system is disclosed. The system may comprise a top panel. The top panel may comprise one or more cut-through openings and one or more flaps. At least one side of the flap may be edged by the cut-through opening. The flap may be configured to flex with respect to the top panel, in response to a press of the flap. At least one of the one or more cut-through openings may be configured to accommodate one or more fingers.

Abstract: A steering system for amphibious vehicle includes a control connected to road steering means. Ram is conventionally used to assist road steering, but by disconnecting command valves, it becomes a hydraulic master cylinder, driving slave cylinder; and thus marine steering means. Valves and hydraulic reservoir enable the marine steering to be disconnected from road steering. The marine steering means may be center biased by springs. A sensor and control means may synchronize center positions of road and marine steering. The valve and port layout may also achieve this goal. Alternatively, power steering in road mode may be maintained by fitting a master cylinder in parallel or in series with steering means; and may have hydraulic, electro-hydraulic, electric, or magnetic assistance.

Abstract: A steering system for amphibious vehicle (100) comprises control (144) connected to road steering means (126). Ram (134) is conventionally used to assist road steering, but by disconnecting command valves (165), it becomes a hydraulic master cylinder, driving slave cylinder (148); and thus marine steering means (121). V represents a layout of valves and hydraulic reservoir enabling marine steering to be disconnected from road steering. The marine steering means may be centre biased by springs. A sensor and control means may synchronize centre positions of road and marine steering. The valve and port layout of FIG. 4 may also achieve this goal. Alternatively, power steering in road mode may be maintained by fitting a master cylinder in parallel or in series with steering means (126); and may have hydraulic, electro-hydraulic, electric, or magnetic assistance.

Abstract: Motor vehicle 12 is towed by a second motor vehicle 10. The towed vehicle has a hydraulic or pneumatic suspension with rams 44 at wheels 46, pressure feed hoses 58, height sensors 60, and signal wires 62. Ride height is normally maintained by an electric motor and pump unit 48. Hydraulic control unit 52 and ECU (electrical control unit) 30 co-operate to pressurize and regulate the suspension when ignition switch 38 is activated. Accumulator 55 may be provided to reduce the number of pump cycles. To allow towing of vehicle 12 with suspension height maintained, but ignition switched off, electrical socket 24 is provided on the towed vehicle. This may be connected by cable 26, 28 to socket 16 on the towing vehicle. A spur (41, 43; FIG. 2) may be taken from the cable to provide power to a trailer-type lighting board. The towed vehicle may be an amphibian.
